After inventing INJEKTO 2.0, our DIY desktop plastic injection machine, we promised you all a detailed video about using custom 3D printed molds. NO MORE NEED FOR OUR DIY CNC MACHINE! In this video we demonstrate how we successfully made molds for custom building blocks (similar to LEGO), bolts, and fishing lures. We hope this testing helps anyone who has been interested. Enjoy!
P.S. This homemade machine works great in tandem with SHREDII, our DIY plastic recycling machine, to turn old 3D prints and other plastic waste into pellets that can then be injected into 3D printed molds.

In the 80's I worked at an injection shop. We made CD cases and such. When making your product, that is thin, you will need to heat the mold so the plastic won't chill before the mold is full. It also helps to use higher pressure as this will get the plastic to the far ends sooner. Next mold, build in a clamping device into the mold itself so you don't need a vice. Take a look at big machines, they keep the mold at a fairly constant temp, use hydraulics to force them together, and use lots of pressure to push the plastic in. We used to make plastic army helmets and getting the mold setup and up to temp took a while.
Thanks for your input 😃.
Something I always recommend to people that want to build a home shop version of an industrial machine is to look at patents and schematics of stuff that already exists. It helps cut out the guess work and gives ideas to what needs to be done, especially as most industry/mass production machines tend to not have any unnecessary pieces. They do the job they’re meant to do and not much else.
@@embers_falling also: go to trade shows and try to talk to the engineers who worked on the product. The first person you talk to is usually a sales person. Ask really technical questions until they refer you to their emergency engineer (mandatory at any trade show). They will usually be ecstatic to talk about all the technical details of their work.
@@WurstPeterl haha so true
@@WurstPeterl ah yes, attacking the weak point of any trade secret: the overly eager engineer
Try waiting 10 seconds or so before taking the injection pressure off. That will fill the sink marks out better!
Agree'd more injection duration
The detail on the resin prints were insane, the fact that the resin looked so clear looked awesome. I look forward to see what you do in the future.
It's quite amazing how far at-home manufacturing technology has advanced, 20 years ago, all you had was a block of wood and a chisel, but now the possibilities are endless. It's also crazy how fast you can now replicate 3d prints at home. Thank you for introducing me and a lot of other people to this amazing technology. :) Good luck in the future
Thank you 😊. Glad you enjoyed. Cheers, Dave
I Absolutely LOVE How easy it is becoming to MAKE things! soon people will be able to HOME Produce professionally made Toys, Statues, Prototypes... and run small productions from their own homes. imagine if He-Man or Ninja Turtles had started like this?!
Love these diy machines. With enough time and tools we can make almost anything. Currently making a mini mill and so far it's been pretty fun.
these home size kits and machines are life changing! you've done amazing work!
Really interessting video! Also that you can just 3d print the molds is insane. Makes the whole process much cheaper than using metal. Genius!
If you make the "escape channels" a zig zagging line or a thin wafer that zig zags between the mold halves, it will more rapidly cool the escaping plastic, allowing the molten plastic still being injected to feed any larger mass areas where you are seeing shrinkage, or "sink marks" as you call them. Search die cast or injection mold chill vent to see what I'm talking about. You can additionally add vacuum to the chill vent to allow for a faster mold fill time (in aluminum die cast at least). I would love to see this replicated on the small scale, with a cross-section of test parts with and without all of those things to see the resulting internal porosity. Very interested in this as a prototyping/small production mechanism for my shop.
That’s a great idea. Thanks for leaving me this comment. I’ll give it a try in one of our next videos. Cheers 😃
It's amazing to see how rapidly you are improving your projects.
It feels like the injecto 1.0 was only three months ago or so, now I see this. You guys are getting better and better :)
I'm so excited for this! I've been waiting for you guys to make 2.0 for a while, this is so awesome!
This injector machine is so cool. I've been following this project for a while. Awesome video
Great videos on injecto 2.0 I love this machine!!
Amazing, some time ago I have an idea to make injection molding using resin mold turns out you already make real working one. Awesome
Looks a great piece of kit. For short runs, resin looks like a great mold material. Deffo want one
I love this, I will definitely try making one for myself!
Very nice! 😀
Cool stuff as always!
I'm a mechanical engineering student and I find your injection molding video's so fascinating. I love your video's!
Thank you 😃
Really very impressive. It is very cool that this is possible. And maybe the concept of using resin printed molds can be used for other purposes as well (for example, candles, who knows what more)
That’s a very cool idea hahah.
The fragility of wax makes it not the best candidate for rigid moulds. It would make more sense to make a resin mould for casting a silicone mould for casting a wax candle, though you're entering mouldception territory at that point.
That looks amazing!
How awesome!!! What a great video
It’s cool to see injection molding machines making it to the consumer market. Good job!
Awesome! Especially liked the clear resin idea...
McMaster-Carr has many 3D .stl files of common fasteners, bearings, clamps, and most things in their catalog too!
And, for the fishing lure, recommend adding a metal eyelet on the forehead for tying off the fishing line.
Thanks for your input 😃
I freaking love your work, your content and your ideas!
I own 2 businesses and I need the Injecto 2.0 for the creation of several inventions, soon I will buy at least one Injecto!
Which you the best success buddy!
Thank you for your support 😃. We look forward to hearing more from you. Cheers, Dave
Excellent product and idea. Sharing to all My colleagues. Keep it up!
Thanks Francis 😃. We appreciate that. Cheers, Dave
cool project
Sounds like you need a modular rig for actuating the extraction pins. Then you'll be able to run the whole process faster
Wow that $1750 will safe small companies soooo much money and waiting time in the future, I didn't know "at home" injection molding was a thing yet and I love it.
Great work and nice video.
You have been making a lot of stuffs. Congratulations!!
Very cool machine
That's so cool
Very Nice machine!
Love this idea
Really cool device. Maybe I will build it in future
Very ccoool!!!
That’s awesome
very cool vid btw
Why yes I would love an injecto 2.0!!
That machine INJEKTo 2.0 is awesome 🤩
I don’t know if anyone else mentioned it already, but Polishing/Lapping/Buffing the Clear Resin can make it more transparent. Was still a great visual even without that though!
Thanks Eric, I’m definitely going to try that for the next video. Cheers.
OMG I want this machine.
Love your Videos 🥰, please make more interesting videos!
Those clear moulde are awesome !
Thanks 😅. Glad you enjoyed the video 😃
Looking good
Really cool, it could be used for making bigger blocks and using scrap plastic such as hdpe, I'm thinking house brick sizes, endless possibilities.
Good video
thx man
What was UA-cam thinking that I found this interesting.
Well UA-cam was right 😂
I realy want and need this machine 👍
Great concept
Thank you
@@ActionBOX I saw lot of DIY IMM but yours project is better.
What a nice idea
Thanks Julian 😃
O.O i need this tool!
Great tool
Thanks 😊
Where do you get the energy to do such amazing things?
Kid: Mom, can I have Lego?
Mom: We have Lego at home.
Lego at home:
Hahaha that’s hilarious 😂
That's very impressive for such affordable tools
Quick question…
recently I rebuilt some of my older sets and I noticed some important pieces missing (be it a piece of a certain colour or just a piece I can’t substitute), how compatible would the pieces be with the actual pieces.
And also, there are some sets I wasn’t able to get that I really liked . How would I go about making molds for the pieces I don’t own (have no reference for)?
These videos are good like candy
That’s cool with one of these imagine what you can create 😱
Cool
woozer!
me: mom can we get legos
mom: we have legos at home
legos at home:
i just had to make the joke lol
Hahaha so funny 😂
Love this! So great to see at home injection molding. How many parts do you typically get per mold? I wonder/assume different resins would last different amounts
Edit:fix autocorrect changing resins to reasons
Thanks Will 😊. The answer really depends on the quality of material you buy for the molds. There are resins more specific to this task but we used the cheapest possible resin and got about 20 parts out before the molds gave up. Hope that helps. Cheers, Dave.
Nice Video
Would this work for fishing baits as well?
Edit: Nvm. It was already covered lol
Awesome
What kind of plastic are you using ? Can you use hdpe to inject to this printed mold?
Thank you.
I am subscribed
Great video! Greetings from Argentina
Thanks Roberto 😃
I would have so much fun using that. I love to design things for real world use, less than toys.
Oh, I wish I had an Injekto 2.0. Good luck everybody .
If I had this I will make America Great Again, that will be the truth 😃 thanks for sharing 🙏
Glad you liked the video.
for the clamping issue: did you try "dome-ing" one side of the mold? I would think that you could shape it so that it doesn't splay out like that under pressure.
Great suggestion Richard. We will give it a try for our next video. Cheers.
this is amazing, injection molding is usually prohibitively expensive especially for high output of parts. The resin molds can revolutionize small scale injection molding
Nice :)
I need Injecto 2.0 :D
When I was in high school or junior high we had an injection molding machine which we could make all kinds of stupid stuff. From chess pieces, rubber bottle caps and a bunch of other stuff. It was super cool. I do not recall how we clamped them.
That’s pretty cool for a high school shop.

Where did you get the pellets?
Also, can you use abs filament as a substitute?
You can easily get the pellets online either on Amazon or eBay. We have successfully recycled 3D prints made of ABS and used them for injection molding, so yes, you can use ABS filament :)
@@ActionBOX Good. I wanted to make sure because I have some filament and want to put them to good use sometime.
Injekto 2.0 can be used to inject plastic into a mini soldier figure (with high details and thin parts) 3d printed mold?
Yes. We will make a video about it
I make tons of plastisol fishing molds at home, would be interesting to see what can be done with thermoplastic. The lures need to be hollow inside with chambers for rattle and balance as well as a way to tie them on.
I'm sure there is a way to do it if you put time to think it through. We've done many interesting projects with INJEKTO.
sadly it's out of my budget right now but maybe a few years down the line@@ActionBOX
we need that machine at Argentina 100%
Billie Ruben's method of using wax to smooth the interior of your mold may help produce smoother results and might also ease the removal process.
I enjoy the projects you do. Any thoughts on selling plans for the bigger machines?
Which machines specifically? Cheers
@@ActionBOX Any. I'm most interested in the full-size injection molder.
sink marks will appear if the wall thickness is thicker than it's surroundings, this means that there is more hot material that will take more time to cool off and therefore it will contract at one side.
solution: Make a new cavity that decrease the total volume of the buttons by follow the outline and have a uniform wall thickness
Thank you 😃
Hi from Iceland, I love your videos and hope win 🙏😃
Is i possible to make long mold to make plastic 8020 rails
That’s an interesting idea. I assume it’s possible with the right equipment.
This will be really cool way to reuse 3d printer supports
Would the sanded(?) sides of the clear molds become more see-through if you added a layer of oil or clear lacquer or something similar on it?
Yes they would. In fact we should have done that in the video. Thanks for a great suggestion.
Which clear resin did you get? I want:-)
Just some stuff we found on Amazon. It was the cheapest option. Works great. Cheers.
You should add a leader to your lures. That way there's something to tie a fishing line to.
Thanks for the suggestion! 😄
wow! this is so great! I hope I win!!! good luck to everyone else as well!
Nice
Thanks
what material or resin are the grey blocks, did you resin print them or 3d print them ?
We resin 3d printed them out of the cheapest resin we found on Amazon
interesting🙂 looks ABS like@@ActionBOX
Dam I wish I had the money for one of these I never knew you could even get a desktop injection machine 😱😱😱
You can now. It’s called “Injekto” Cheers, Dave
This 2.0 looks really good.
Thanks 😃
If you keep recycling PLA with your injection machine will the quality get worse over the cycles?
Yes, it will. Hope that help. Cheers
