As always, Thank you for your time and effort! If you don't believe your accomplishing enough, that's just the enemy trying to discourage you. Don't let it! I had friends bring me a paper straw from their world travels. That meant more to me than the t shirts!
Hello. My husband has been in the plastic industry for 40 years. I asked him his opinion on using a release agent for your sheet press. He suggested using powdered zinc sterate, easily accessible, fairly cheap, works great. Back in the day that’s all they used. May work for you. Keep up the great work you do!!
If hdpe is melting during cnc cutting it is because you are cutting too slow (not too fast as stated). You must increase chip size, by slowing rpm or ideally increasing ipm speed.
It's so inspiring to watch these monthly visa, Im always look forward to watching them. Living sustainably and making people aware of plastic pollution is awesome and the community you have built seems so healthy and fun! I'm under 18 and doing an apprenticeship course and know nothing about plastic properties but I would love to one day join the precious plastic fam!
To cut plastic on the CNC machine, use single flute cutter and air for cooling. I used around 15000 to 20000rpm with 6mm cutter and 1000mm/min feedrate. For better finish use 0.3mm -0.5mm finish cut.
To make the table less wobbly you can use octagonal shape instead of rectangle. Cool idea! Just plastic nothing more, no screws no glue I see a potential in this thing, ikea may be interested in products like this :)
Dave I’ve watched your videos for awhile. You always had such great content. I usually don’t tune in for a year or more so seeing this crazy large team and all of this progress you’ve made is freaking awesome. YOU ARE FIXING THE PLANET!!!!!
Love the community and the great new ideas, some ideas for the cold press: Maybe the introduction of venting channels used in casting applications can direct excess material to certain point of the mold and help the plastic spread. The introduction of detachable sides ( frame and plate construction, like old baking forms from grandma) of course bolted or sleeved construction in your case can help to detach the big plastic plate. You can also implement a Cooling circuit from a parted out car to help cool the tool during and after the press cycle. Good luck and blessings to you all
For mould release you could try glycerine from biodiesel manufacture. Its the waste left over from making biodiesel and has some interesting properties one of which is form release for concrete or for the beds of trucks transporting tarmac. It can also be used for cutting fluid, making soap, chainsaw bar oil, and much more. It's also easy to make if you can find a source. Oh its biodegradable too :)
I really like those big panels! A room walled in panels like that would be great! A shower room would be interesting. A plastic tiled wall? Floating shelves? Made into Stairs? Or some paintings on them. Some are pretty by themselves but I’d like to see them used as “canvases” for artwork. Lovely!
And..for my 2 cents worth...I know iso code for Maho milling equipment. Water cooling is used to cool cutting distortions. You will make tons more product and thus money by concentrating on smaller products. A punch press stamping out nursery pots would be tens if thousands of items a day, made from thinner thus faster produced more energy efficient production. Key chains, bottle stoppers, pouring spouts. Heck, to raise money, a set of plastic Christmas cards. I'll buy a box. Never have to mail the person who gets one another! The problem with the world is always what's new. Tubing square or round will never go out of demand. Plastic covered wooden handles for your garden hoe. Why grind 2 or 3 liter bottles up? Hot press them into the next item. They don't need to hold soda, dirt is more useful. Grow food or ornamental plants.
With the plastic bottles, fill them with water and put a LED inside, the water will help the light to spread. each bottle is a pixel and you could have any light show you want, world map, Precious Plastic logo..... With the hot press would it be possible to have the aluminium plates coated with PTFE like a frying pan, maybe help with the wrinkling. With the cold press you have the tubes welded together to form the plates, could steam be used inside the tubes to turn it into a hot press and also cold water to help with cooling. Just a couple of ideas.
Hi there, you guys were saying you have some trouble with sturdiness on your furniture. Just after watching this video I found some good examples of how to use these recycles plastic sheets or even recycled plastic cylinders. Search for "playforce", they produce playground and leisure equipment, you can get yourself some inspiration form there. They use stainless steel brackets to mount the plastic sheets to each other or use similar methods as you with cutouts, so they fit together. I think you are almost there, just a bit more tinkering to get the know how to create a sturdy structure. For instance with your stool, you had the long side of the plastic profiles in only one or two dimensions, you need them in all three dimension to give it strength, otherwise it will bend vertically to the short side of the profile. For instance, if you create a rectangle, it will be weak and probably collapse into a parallelogram, so one thing to stop this, would be to put a diagonal brace into it. If you have something to keep it form rocking in all three dimensions, your are there. Have a look at traditional wood joinery as well, as they will have the same issues. Lots of design out there, without nails, screws and brackets, if you like to go that way. IKEA can also be a goo inspiration for good designs. I am wishing you all the best and keep it up, don't let anybody tell you, you cannot do it. With persistence you can achieve anything.
Wish I could go there. Unfortunately I'm broke and can't afford the airfare, lodging, food etc.. Looks like an awesome community you have made there. Love the atmosphere. There's also soo much I could learn there. Planning on starting a consumer product business and planning on using mostly recycled plastic.
to get faster cooling on the presses, you can run a glycol or water loop on the metal plate surfaces and use the 'waste' heat in the liquid to pre-heat something else (domestic hot water, water-based space heating equipment, etc). with so much energy going into just electric process heat you can really increase the energy efficiency at your space by re-purposing the 'waste' heat. double benefit with efficiency and improved cycling time on your press!
Interesting video. Does anybody still reads new comments seven months after the video has been released? Plastic (new or recycled) is just a material, like everything else. You can apply techniques from other branches of industries. For example with the hot press for the sheets you might take a look how (industrial) bakers do not have their products (bread and so on) stuck to the baking plate. The foil does not work 100%, maybe oil or grease does? The same is for the stool. It was mentioned and shown that it is a kind of wobbly. Watch and uses techniques how wooden stools are made. Btw thanks for the ideas how to you old coffee grout (or how is it called?).
Hahaha thank you for putting my comment 0:42 . I love what you do and its interesting how your machines are upgrading and all of your projects ,keep up the work!
Idea for the mould: Build it out of a flat metal plate and a frame that can be screwed off to remove the plastic after the melting process. Idea for the presses: Add active cooling with air or water. Air cooling shoud be easy on the cold press, just add some ventilators to the pressing plates. For the hot press, I would use copper or aluminium pipe and a water cooling. After the cooling, use compressed air to empty the pipes before you heat the press up again.
Really interesting... 👍 A step forward on the explanation of the news of Version 4. Thanks a lot for the sharing to the video team ... Ps: @mike hard worker 😉
the wobbling table; use angled plastic(like angle line steel) for the legs. with that you can make them even as thin as 6mm and they'll be much sturdy. The 30,000 plastic bottles. sounds like a huge quantity given the number, but very light when weighed. I've been doing a housing project here in Kenya with plastic bottles but needs tonnes of plastic. I'd suggest you build some dog kennels with them. I can share some ideas about that with you...
These huge amounts of plastic material can be used for the organic growing vegetable in the air kits, to sell to the public for home and commercial vegetable industry.
The best use for those thousands of bottles I can think of is the TrussFab project by Hasso Plattner institute in Germany. It is both artistic and utilitarian at the same time. I have attached a link in the reply.
For joining plastics: try ultrasonic welding. That might be too industrial, but it would be amazing if you could come up with a cheap method. It’s great to follow your progress.
Nice guys. For the shaping and testing on how far things can go you shoukd get incontact with a composite decking material such as aztec decking and try and learn that there processing and manufactuing. They might be able to help withthe learning curve since they probably already have the experience of testing and what works amd doesmt work. Alot of composite decking is extruded with a internal frame structure instead of a solid block. Which would help with the wobblyness such as the table. Also you shoukd take an oven that warms the plastic up (not melt) so you can curve and re shape.
The small coffee table is wabbly because you don't have ties lower down on the legs. Get them on no wabble. Pressed sheet is the simplest form of injection moulding. Make the injection mould with water cooling on both cavity and core sides use screw to inject the melted plastic and hydraulic clamp to hold down the mould while cooling. 30,000 bottles can make a hell lot of broom sticks. I'll include the link to my FB page if you are interested.
make a biodigestor to recycle all your vegetable waste and the poop from all of the workers. You can make biogas with it to heat the workspace! made one for my final work on school, and worked great!
One thing is that your furniture uses a lot of plastic. The industry is focused on making products designed for narrow purpose with necessary strength requirements, little weight and material use. Making shipping palettes, reusable creates, furniture and by making it all by using triangles and corrugated sheets of plastic. So the shipping costs and CO2 impact would be low. Plastic is pricey! We need efficient automated processes to recover it. From collecting, disassembly, sorting, recycling, manufacturing, distribution.
Hi guys! For you mould release issues and wrinkling in the ptfe look into LUX or spray ptfe. Let me know if you are still having issues. Happy to come support.
What may be a way to help with the releasing of the plates in the cold press is by adding big draft angles to your mold (lets say 20 to 30 degrees). I saw in the video that you guys have 0 degrees draft angle. I'm working at a company that makes a biodegradable packaging solution and when designing the packaging I seriously need to take draft angles into account. (production is very similair to plastic injection moulding) Cheers and good luck ps. (Planning to make my own little household recycle plant and filament extruder to use in my 3d printer)
Use water jets to cut plastic that will not melt i guess and again with the grinder, you can use more water while cutting the shits which will remain cool while cutting and that will help in getting a clear cut. good job guys
Hey Dave! We here in eastern Germany, especially Zeitz, have a looooot of free space, infrastructure and a developing artist community. Since many people left when the wall fell there are concepts needed to fill in all those empty houses. Reach out to Philip Baumgartner from Kloster Posa here in Zeitz/ or shoot me a message.
You should take the bottles and build an island then grow food on top of the artificial island in a hydroponic system utilizing solar/ a bicycle to power the pump
the time spent into making these plastic sheet machines could be used to make plastic brick making machines... plastic bricks seems more useful than plastic sheets, because we can build houses with them... just an idea, but it always amazes me the progress and creativity! keep up the awesome work!
I love what your group is doing. To help, I recommend dry PTFE (Teflon) lubricant for the cold sheet press. Remove all plastic and polish the pan as best you can, to make it as smooth as possible. Clean with alcohol to remove any polishing compounds, grease from fingers, etc. Then spray with dry PTFE lubricant. This may also work with the hot press to reduce wrinkles, instead of using the PTFE sheets. Since you are currently in the Netherlands, here is a link for one such product, on their major online shopping site: www.bol.com/nl/p/motip-ptfe-droog/9200000058270611/
perhaps using some kind of silicone mold with an aluminum plate at the back to keep it rigid. Then you could flex the mold to release the plastic assuming it doesn't bond with silicon.
also, to answer the last question, in the end of the video, about what to do with the 30,000 plastic bottles, it would be great if you guys did build a plastic brick making machine (or just a mould) and for the next exposition next year you made a HOUSE with those 30,000 bottles (and gave it to a homeless person for free), showing that all that pollution became a house for someone in need of it.
"It is believed that the first bottle house was constructed in 1902 by William F. Peck in Tonopah, Nevada. The house was built using 10,000 bottles of J. Hostetter's Stomach Bitters which consisted of various herbs in a solution of 47% alcohol." from: en.wikipedia.org/wiki/Bottle_wall @@kevinwamaya6899
molds are the area you guys should should focus on making, because most things in the plastic industry are made through the molding process, things are thinner and stronger when you make things in a 3 dimensional mold. I would focus on injection molds and press close molds!
If you guys have to move, and are thinking of a different country. Why not Alaska? Most houses have 3000sq ft shops and are priced in the 200-350k range. Plus our recycling transfer sites just end up at a central land fill.
Find more info about sheets and sheet pressing right here: davehakkens.nl/community/forums/topic/v4-sheet-press-development/ join the discussion and send me your ideas
Hello Dave and all. I have just found your channel. I am a lecturer on Forestry in Indonesia. My students and I are doing paper recycling. How could I have more info on plastic recycling and of course also on your program. Thank you.
Hello fellas, I really love you're ideas. But there's one question in my mind. Isn't the maine problem with plastics that it ends up as microplastics polluting soil and water,... . There are barely studies about microplastics, but I don't expect good news. What's you're opinion how to tackle the issue of microplastics?
I cannot speak for these guys, but I believe, that micro-plastics are generated by degradation of plastics, especially in uncontrolled environments (non-recycled rubbish floating about in the seas and ending elsewhere in nature). The UV radiation and physical erosion will turn plastics into micro plastics. So from my understanding, the easiest way to avoid micro-plastics is to recycle the most you can, that way you minimize the plastic that just rots away unseen outside the cycle. When you recycle it, melt it down again and mould it, it will basically give the same plastic a fresh start, so it prolongs the total lifespan. You can also throw anti-UV additives into the mix, too. When it actually is micro plastic and then trying to collect it again, that will be hard, unless you count, what the food chain automatically does, right now, as it is filtered through lots of organisms including us and stays in our bodies until we die. This will work, I believe, similarly to mercury, it will likely build up as you go up the food chain. So we, wales, high up predators will get the worst of it.
I built an extrusion machine and just use cold water on the mould to create shrinkage for the release of materials. It might ruin your metal mould eventually but provides release in seconds. I've also got a friend that irons plastic bags together (fuses them - www.aoracreo.com ) and then vacforms that sheet into all kinds of things, maybe your guys should have a look at building a vacformer (its super easy)? Love what you are doing, keep it coming!
Dave did you see Shifphones? It might be worth a look. They're working on fair repairable and modular phones...now that you brought up Phonenblocks again for a second ;)
Wish I could use this in the Arizona Desert but Steel companies here are asking way to much to make the parts to make the extruder alone is over $4000 to have the parts made if you are starting from scratch do you have resource that we can go to in the copper state of Arizona USA? I would like to make many projects with recycled plastic but do not know where to start or get help to get the machines built. I will keep looking for junk yards and other metal places to see if they can help but the pro shops to get the parts made is crazy expensive for normal people to get a hold of. Take care love the project and hope more people int he US will follow this project :)
hey i just got to discover your channel but each time i try to download ur schemes and blueptints i just get a blank page telling me i cant get to the page, anything i can do to get them, i am really eager to start building my own machine and get into action i am tired of just watching videos
There's an English famous UA-camr that just made a very nice double jaw shredder... His name vanish from my mind now... The fireworks one... Fuck my memory!
Is it possible to do an internship more or less at your place? I'm very interested in this whole concept of your channel and what this community tries to accomplish and I thought an internship could support my current studies in engineering.
ola amigo davehakkens tudo bem manaus AM brasil eu gosto das suas ideias e aproveitando gostaria de saber como ficaria uma telha feita a partir do PET. e que tipo de material pra fazer a forma pra não ficar falha, nesse forno de pizza seria viável a fabricação da mesma grato
As always, Thank you for your time and effort! If you don't believe your accomplishing enough, that's just the enemy trying to discourage you. Don't let it! I had friends bring me a paper straw from their world travels. That meant more to me than the t shirts!
Hello. My husband has been in the plastic industry for 40 years. I asked him his opinion on using a release agent for your sheet press. He suggested using powdered zinc sterate, easily accessible, fairly cheap, works great. Back in the day that’s all they used. May work for you. Keep up the great work you do!!
I am Portuguese and can assist! I offer my assistance mooonnnths ago before Dave visited Portugal!
If hdpe is melting during cnc cutting it is because you are cutting too slow (not too fast as stated). You must increase chip size, by slowing rpm or ideally increasing ipm speed.
Thank you we'll work on that 😬
Correct!
It's so inspiring to watch these monthly visa, Im always look forward to watching them. Living sustainably and making people aware of plastic pollution is awesome and the community you have built seems so healthy and fun! I'm under 18 and doing an apprenticeship course and know nothing about plastic properties but I would love to one day join the precious plastic fam!
You guys are awesome!! Love and miss you all!
To cut plastic on the CNC machine, use single flute cutter and air for cooling. I used around 15000 to 20000rpm with 6mm cutter and 1000mm/min feedrate. For better finish use 0.3mm -0.5mm finish cut.
To make the table less wobbly you can use octagonal shape instead of rectangle. Cool idea! Just plastic nothing more, no screws no glue I see a potential in this thing, ikea may be interested in products like this :)
Dave I’ve watched your videos for awhile. You always had such great content. I usually don’t tune in for a year or more so seeing this crazy large team and all of this progress you’ve made is freaking awesome. YOU ARE FIXING THE PLANET!!!!!
Love the community and the great new ideas, some ideas for the cold press:
Maybe the introduction of venting channels used in casting applications can direct excess material to certain point of the mold and help the plastic spread. The introduction of detachable sides ( frame and plate construction, like old baking forms from grandma) of course bolted or sleeved construction in your case can help to detach the big plastic plate. You can also implement a Cooling circuit from a parted out car to help cool the tool during and after the press cycle. Good luck and blessings to you all
For mould release you could try glycerine from biodiesel manufacture. Its the waste left over from making biodiesel and has some interesting properties one of which is form release for concrete or for the beds of trucks transporting tarmac. It can also be used for cutting fluid, making soap, chainsaw bar oil, and much more. It's also easy to make if you can find a source. Oh its biodegradable too :)
Speaking you guys shoud get into that for a fuel sourcesince youll need power in the kamp
In Portugal there are cheap big places i and a lot of patrimony like (Nazaré , Algarve...) And there's is a lot of elderly
And my dad knows a lot of cool places and cool communities
What about polishing those aluminum plates on the flat sheet press to a super fine finish and just use them bare or lather it with some cooking oils?
I really like those big panels! A room walled in panels like that would be great! A shower room would be interesting. A plastic tiled wall? Floating shelves? Made into Stairs?
Or some paintings on them. Some are pretty by themselves but I’d like to see them used as “canvases” for artwork. Lovely!
And..for my 2 cents worth...I know iso code for Maho milling equipment. Water cooling is used to cool cutting distortions. You will make tons more product and thus money by concentrating on smaller products. A punch press stamping out nursery pots would be tens if thousands of items a day, made from thinner thus faster produced more energy efficient production. Key chains, bottle stoppers, pouring spouts. Heck, to raise money, a set of plastic Christmas cards. I'll buy a box. Never have to mail the person who gets one another! The problem with the world is always what's new. Tubing square or round will never go out of demand. Plastic covered wooden handles for your garden hoe. Why grind 2 or 3 liter bottles up? Hot press them into the next item. They don't need to hold soda, dirt is more useful. Grow food or ornamental plants.
I love the heat and cold press machines. really cool
With the plastic bottles, fill them with water and put a LED inside, the water will help the light to spread. each bottle is a pixel and you could have any light show you want, world map, Precious Plastic logo.....
With the hot press would it be possible to have the aluminium plates coated with PTFE like a frying pan, maybe help with the wrinkling.
With the cold press you have the tubes welded together to form the plates, could steam be used inside the tubes to turn it into a hot press and also cold water to help with cooling.
Just a couple of ideas.

Thank you beautifull people for trying to make the world a better place!
This press is amazing!!
For mould release we use silicone to protect the interior of the cars ... Greetings from Colombia - Plástico Infinito
hot and cold sheet press are awesome and results are awesome. I would like to see gigantic shredder and the blueprints too. You guys are amazing.
The cloth press, you could try to use compressed air to cool/release and get flattened results after melted material was place in pan and compressed.
Interesting video. Does anybody still reads new comments seven months after the video has been released?

If you want to get good clean cuts in the sheets you should try using a water jet cutter.
These huge amounts of plastic material can be used for the organic growing vegetable in the air kits, to sell to the public for home and commercial vegetable industry.

Nishant Agarwal cool project, but it would be boring to just copy it. Definitely good inspiration though.
You should get a bigger CNC and make the stuff from Opendesk. That new sheet is very exciting! Waiting on V4 to build our kit! Good luck guys!
For joining plastics: try ultrasonic welding. That might be too industrial, but it would be amazing if you could come up with a cheap method.

Pressed sheet is the simplest form of injection moulding. Make the injection mould with water cooling on both cavity and core sides use screw to inject the melted plastic and hydraulic clamp to hold down the mould while cooling.

Think about a continuous sheet making machine using heated rolls pressing molten plastic to a certain thickness. It cools down the road.
make a biodigestor to recycle all your vegetable waste and the poop from all of the workers. You can make biogas with it to heat the workspace! made one for my final work on school, and worked great!

Hi guys! For you mould release issues and wrinkling in the ptfe look into LUX or spray ptfe. Let me know if you are still having issues. Happy to come support.
i though about making some kind os sheets / plates to use as kitchen tiles, those that u guys showed are pure ART
What may be a way to help with the releasing of the plates in the cold press is by adding big draft angles to your mold (lets say 20 to 30 degrees). I saw in the video that you guys have 0 degrees draft angle.

I look forward to developing this model in Vietnam to help children know more about environmental protection !
Use water jets to cut plastic that will not melt i guess and again with the grinder, you can use more water while cutting the shits which will remain cool while cutting and that will help in getting a clear cut. good job guys
Water is (maybe)even more precious than crude oil. Maybe it is possible to use salt water.
wooly pully marine corps sweater! nice!

Hello from Fiji...i think you guys are awesome. 😊
I love the new machine
I would love taking all those bottles melting them into sheets and then building a boat.
Good job 👍👍👍👌
Hey guys :) Did you think about a machine to create yarn? Everything gets easier if there´s a way to weave and sew. Keep on going, guys. You rock!

You're lovely team
perhaps using some kind of silicone mold with an aluminum plate at the back to keep it rigid. Then you could flex the mold to release the plastic assuming it doesn't bond with silicon.
also, to answer the last question, in the end of the video, about what to do with the 30,000 plastic bottles, it would be great if you guys did build a plastic brick making machine (or just a mould) and for the next exposition next year you made a HOUSE with those 30,000 bottles (and gave it to a homeless person for free), showing that all that pollution became a house for someone in need of it.
30,000 plastic bottles can't make a house, maybe a kennel.
"It is believed that the first bottle house was constructed in 1902 by William F. Peck in Tonopah, Nevada. The house was built using 10,000 bottles of J. Hostetter's Stomach Bitters which consisted of various herbs in a solution of 47% alcohol."

molds are the area you guys should should focus on making, because most things in the plastic industry are made through the molding process, things are thinner and stronger when you make things in a 3 dimensional mold. I would focus on injection molds and press close molds!
Why not coat the heat press with High temperature rtv silicone?
I think we can use non stick layer, like we use in non stick pans.
If you guys have to move, and are thinking of a different country. Why not Alaska? Most houses have 3000sq ft shops and are priced in the 200-350k range. Plus our recycling transfer sites just end up at a central land fill.
Also for the hot press, had you considered using cold water coils for cooling?

Joh in Helmond zag ik! Zoveel creativiteit in mijn eigen home town! Waar zitten jullie dan?
Have you thought about trying water Jets for cutting. they aren't to complicated to make.
1:40 Hello darkness my old friend
Hello Dave and all. I have just found your channel. I am a lecturer on Forestry in Indonesia. My students and I are doing paper recycling. How could I have more info on plastic recycling and of course also on your program. Thank you.
Make a giant plastic bottle out of plastic bottles. Mind blown.
Hello fellas, I really love you're ideas. But there's one question in my mind. Isn't the maine problem with plastics that it ends up as microplastics polluting soil and water,... . There are barely studies about microplastics, but I don't expect good news.
What's you're opinion how to tackle the issue of microplastics?
I cannot speak for these guys, but I believe, that micro-plastics are generated by degradation of plastics, especially in uncontrolled environments (non-recycled rubbish floating about in the seas and ending elsewhere in nature). The UV radiation and physical erosion will turn plastics into micro plastics. So from my understanding, the easiest way to avoid micro-plastics is to recycle the most you can, that way you minimize the plastic that just rots away unseen outside the cycle. When you recycle it, melt it down again and mould it, it will basically give the same plastic a fresh start, so it prolongs the total lifespan. You can also throw anti-UV additives into the mix, too.
When it actually is micro plastic and then trying to collect it again, that will be hard, unless you count, what the food chain automatically does, right now, as it is filtered through lots of organisms including us and stays in our bodies until we die. This will work, I believe, similarly to mercury, it will likely build up as you go up the food chain. So we, wales, high up predators will get the worst of it.
Maybe a powerful suction cup could help with the mold reales
For the chair and table construction have you tried to crossbrace?
Good ol' Presh Plastic 😊

I built an extrusion machine and just use cold water on the mould to create shrinkage for the release of materials. It might ruin your metal mould eventually but provides release in seconds. I've also got a friend that irons plastic bags together (fuses them - www.aoracreo.com ) and then vacforms that sheet into all kinds of things, maybe your guys should have a look at building a vacformer (its super easy)? Love what you are doing, keep it coming!
Next year can you make an exhibition with 10,000 plastic water bottles to represent the amount used over an average lifetime? :)
The project is very nice. How can i make my own machine? Do you have a tutorial or something like that?
Place an i section to the legs of table it will not wabble after that like a frame nearly to the ends of the legs
Dave did you see Shifphones? It might be worth a look. They're working on fair repairable and modular phones...now that you brought up Phonenblocks again for a second ;)
Wish I could use this in the Arizona Desert but Steel companies here are asking way to much to make the parts to make the extruder alone is over $4000 to have the parts made if you are starting from scratch do you have resource that we can go to in the copper state of Arizona USA? I would like to make many projects with recycled plastic but do not know where to start or get help to get the machines built. I will keep looking for junk yards and other metal places to see if they can help but the pro shops to get the parts made is crazy expensive for normal people to get a hold of. Take care love the project and hope more people int he US will follow this project :)
What program / service / website / language is used to display the website content like that !!! (@ 6:17 ish)
Thank you !!

Do the same light show & display in a bigger city. Come to miami
You use ptfe foil, maybe a coating is an option (if possible)
Pls streaming every day!!!!!!
I wish someone was doing this here in Portland Oregon. Does anyone know of anyone processing plastic in this grassroots way in the Pacific Northwest?
Use plastic in farming for plant mediums in hydroponics try share about information
what if you use a zig zag plate for the weld press instead of the flat one?
Hello from Nepal 🇳🇵🇳🇵🇳🇵
What software do you use for visuliation 6:16 ?
hey i just got to discover your channel but each time i try to download ur schemes and blueptints i just get a blank page telling me i cant get to the page, anything i can do to get them, i am really eager to start building my own machine and get into action i am tired of just watching videos
What do you do with those plastic sheets?
There's an English famous UA-camr that just made a very nice double jaw shredder... His name vanish from my mind now... The fireworks one... Fuck my memory!
Is it possible to do an internship more or less at your place? I'm very interested in this whole concept of your channel and what this community tries to accomplish and I thought an internship could support my current studies in engineering.
I'm From Portugal! Actually trying to build some of your machines, i would really like to help
polished metal like stainless steel or ceramics.
when will v4 be presented?

davehakkens tudo bem manaus AM brasil eu gosto das suas ideias e aproveitando gostaria de saber como ficaria uma telha feita a partir do PET. e que tipo de material pra fazer a forma pra não ficar falha, nesse forno de pizza seria viável a fabricação da mesma grato
