Great video. Thanks for sharing. I am doing molds in Fussion, and I am sculpting the final part itself, then the mold where I leave a 4-5 mm gab between the part and the rigid mold. I then print booth and I pour silicon between the part and the mold. This way I can use your technique but also have a silicon mold that allows undercuts and easy removal. Just a small way to make it.
I’m going to create molds for reproduction of motorcycle fork boots that are no longer made. Hopefully I can find the right materials and process to make this work
Nice work at home , few suggestions, 1st you should think about injector pins , 2nd thing for glass type of component you should rotate mould with some speed that will gives better finish to component and even wall thikness , anyway love to watch it 👍👍👍👍👍
Well done. If you're 3d printing the mold though, you can create it in blendr without having to design it. You can still add the mold keys in there as well. It's all done from the model you want to mold. It's unbelievably easy. I was shocked how easy it is.
I would imagine it's a very similar process to mold creation on Fusion 360...basically just a boolean operation to remove the part volume. Is that how blender handles it?
Hello, Awesome video! i am looking to get into foam molding, and just looking for recommendations on flexible foams, similar to like a koozie consistency. do you have any you would recommend?
Thanks! This started with me making my own actual nerf rival balls. Its tough to get the right firmness without making them too hard on a consistent basis though. I will be testing smooth rival balls in an apollo eventually to see if I can reduce the magnus effect trajectory curvature.
I've made silicone chocolate molds, but I'm not sure if that's the process you're referring to. Is that the process you mean or are you thinking the vacuum formed molds you pour into?
@@EngineeringAfterHours it's similar but the overall sicone used in commercial ones are very little. I believe they use a 2 part silicone method to achieve those results vs doing it home made with just pour in method seems to waste a lot of silicone.
So Ive designed a two part 3D printed mold with keys, using Flex Foam It 15 Tuff Stuff, and petroleum jelly for release. So far the results have been horrible. The skin is very poor with holes all over. I know its not recommended but should I try the Mann 200?
Amazing video! I have some many questions, I’m trying to make silicone molds from a 3D printer to mold resin. Are there any resources or tutorials you’d recommend? Anyone’s input would be great! Thanks. P.S. Subscribed :)
Were you ever able to get the "skin" on the foam 15? I 3d printed molds and used foam 14 and could never get any sort of outer layer to form. It was always way softer than the samples.
Hey great video, helped me with my attempt to find a solution. I'm currently printing an item that is like an arm about 5in long 2.5in wide in PLA. 3D printing them is taking too long and want to make quantity in shorter time. We don't need the final item in PLA but just some plastic (ideally not flexible), what would you recommend using for doing this? Injection mold approach would cost $2k-5k in just the tool and then the mold itself. I saw someone using milliput as an option and even epoxy for molds. Any advice would be greatly appreciated. Thanks
I literally made my own Injection mold machine, learned how to pour metal and made my own foundry, 3d printed a master negative mold, then poured it in aluminum for the plastic Injection machine. Now- I can make anything I want in mass (ish I mean Injection isn't SUPER fast). All I have to do is print, cast, Inject. Have tried a handful of epoxies and none of them last anywhere near what you'd need for plastic injection, but the epoxy WOULD last for ever for anything not 550° lol.
I don't believe food safe means suitable for prolonged contact with skin, but you may check with the material suppliers. I use smooth on and alumilite mostly
It really depends on how you define complexity. But I would generally use Silicone molds for complex stuff with undercuts as shown in this video: ua-cam.com/video/LBnUZ-AEuWw/v-deo.html You could also do a multi part mold like you see in production tooling.
"The Fleshlight material is a secret combination of high-quality mineral oil and rubber polymers, and it's protected by a series of U.S. patents." Not anymore!
did you make the launcher at :35? I've looked through your videos trying to find a tutorial because you said it was in your last video but I don't see any info on it
I am looking to make a mold for a ridged piece. The piece you did in this video when you filled the bottom with the resin and put the top on where did the displaced resin go? do I need to design a place for the extra to bleed out of?
There's a few ways to do it, and I have 3 other videos on molds so you may get an example from those that will work on your parts. Generally, I like to allow for overflow in all of my molds
Can glass fiber strands and hard urethane make a good tank track? It takes for ever to print 120 tracks. I was thinking of making them using this molding technique. I'm not sure if it's cheaper or more expensive that filament. What say you?
I have a resin printer. What can I use to fill the molds? I usually do amazing casting resin but I'm sure it will adhere to the 3d printed mold... please help!
@@EngineeringAfterHours so just to understand it right you print the object you want to print then you spray on it a release and then you pour silicon on it ? And that would be the mold if yes do you have a video explaining the procedure like for example what silicon is used and how and if a vacuum is needed thanks in advance
Silicone doesn't stick to much of anything so you can use quite a few options. I generally go with what's easiest for me to get a good surface finish on, but you may contact the silicone vendor if you have special needs or concerns.
It depends on the foam you use...I would check with the manufacturer. These foam molds were either PLA or Eco ABS. Epoxies and such commonly cure hotter.
I've never made a cigar mold and dont know much about them... But if it's just a mold to shape cigars I dont see why you couldn't. Unless it was a complex geometry...I would still prefer to CNC it.
Hi, thanks for the interesting video first of all! 🙂 I do have some remaining questions however ... hope they reach you. It would really help me out! - when printing my molds, the surfaces don't align very well. Which causes leaks... (and nightmares) Wondering if this is due to the printer, printer settings or some other stuff. In other words how do you avoid this? - How can you avoid / minimize parting lines on theproduct? (If it even is possible) Thanks !! Looking forward to the answers. @engineeringafterhours
It sounds like your printer may be distorting the molds a little if the surfaces are flush in your CAD model. The parting line issues can come from mismatch between mold halves, large layer lines and even high injection pressures distorting molds. Maybe cleaning up the parting line and solving the issues with distortion would clear all that up.

thanks for sharing, i always look out for 3d printed mold stuff, im amazed youtube held out and didnt show me your vid for 9 months!
UA-cam is a mystery sometimes. Thanks for the kind words!

As I watch this video, I'm wondering how have handled the print lines in the final mold so that there are no lines showing up in the cast
Thx I learn before is always good
Brilliant work mate

Thought about using TPU for printing moulds for ridged material? you's have the flexibility to remove the part then.
Sounds like a fun project. I may have to give it a shot at some point when I start working with TPU.

Nice. Finally I will try it.
Great Video.. and I wonder what material you using.. to printed 3d mold.. filament ABS? I think this is best way than create mold using silicone..
Amazing video, well explained, awesome video footage! You got a new sub ;)
Thank you for the kind words!
Great video
Interesting video good job.
Awesome topic and decent video edit. Good work.

You should so a candy/Chocolate mold that are similar to commercial made. I would love to see that process being done.

hi thanks for the instructions, I want to make a pla mold for epoxy resin, what do you think I should use as mold release ?
If I want to make a solid 3d mold what would you suggest I use I know I want a extra large printer but I need to learn how to use it too

Mate I need a molding stuff like rubber just like you used. What would you suggest?
What's the density on the foam your worked with for this video ?
Are there any food safe epoxy so you could make a mold for a mask/respirator
I don't believe food safe means suitable for prolonged contact with skin, but you may check with the material suppliers. I use smooth on and alumilite mostly
Any tips on very complex parts? This geometry are usually very ease to cast, but what about a rigid part with a little complexity in geometry.
It really depends on how you define complexity. But I would generally use Silicone molds for complex stuff with undercuts as shown in this video:
ua-cam.com/video/LBnUZ-AEuWw/v-deo.html
You could also do a multi part mold like you see in production tooling.
LOL I wonder how many nerds just got inspired to make a fleshlight.

Thanks man
Happy it helped!
did you make the launcher at :35? I've looked through your videos trying to find a tutorial because you said it was in your last video but I don't see any info on it
I did and for some reason I pulled the video down. It was just basically a t shirt cannon.
I am looking to make a mold for a ridged piece. The piece you did in this video when you filled the bottom with the resin and put the top on where did the displaced resin go? do I need to design a place for the extra to bleed out of?

Could you show please from where we can buy the materials? For example could show the links on Amazon (DE) please?
I couldn't find the material on Amazon(de). Recently I've bought directly from smooth-on or alumilite.
Can glass fiber strands and hard urethane make a good tank track?
It takes for ever to print 120 tracks. I was thinking of making them using this molding technique.
I'm not sure if it's cheaper or more expensive that filament. What say you?
It will probably cost more than filament...but it'll be mechanical superior.
Which silicone molding material were you using? Thanks!
Most likely a smooth on product. The foam was for sure smooth on, sometimes I use Alimulite.
0:42 I thought this was dog food 😂
Do the layer lines show up when using 3d printed molds out of the pla?
Yes
@@EngineeringAfterHours I figured but there was that slight hope somehow, thank ya
The million dollars question is which 3D printer was used to print that molds ?
Dremel 3D45. It's been a very solid printer.
I have a resin printer. What can I use to fill the molds? I usually do amazing casting resin but I'm sure it will adhere to the 3d printed mold... please help!
are you looking for a mold release? In this case I just used chap stick or Vaseline.
so you are making a mold for a silicon modl to use it later with epoxy ?
I have made silicone molds multiple times and should have a few examples of that on other mold making videos.
@@EngineeringAfterHours so just to understand it right you print the object you want to print then you spray on it a release and then you pour silicon on it ? And that would be the mold if yes do you have a video explaining the procedure like for example what silicon is used and how and if a vacuum is needed thanks in advance
@@EnergySeeker ua-cam.com/video/LBnUZ-AEuWw/v-deo.html
I think this one explains it.
@@EngineeringAfterHours thanks a lot
This is great!
What filament material would you recommend for silicone Molding?
Silicone doesn't stick to much of anything so you can use quite a few options. I generally go with what's easiest for me to get a good surface finish on, but you may contact the silicone vendor if you have special needs or concerns.
2:27 come on, we know that's a fleshlight! Just admit.
does the foam cure hot or cold? I'd like to know if I can use PLA or need to go buy abs.
It depends on the foam you use...I would check with the manufacturer. These foam molds were either PLA or Eco ABS.
Epoxies and such commonly cure hotter.
@@EngineeringAfterHours huge temp difference in pla or abs. I called smooth-on, said only 90f, so thats probably wha i'll try! tyty
Eco ABS is actually just a modified PLA product that dremel markets as having ABS like properties. It has a much lower temp rating than true ABS.
@@EngineeringAfterHours ah, so many choices... sounds like pla will work just fine for me in this case. Fingers crossed!
@@DarksealStudios just make sure to take into account the foam expansion!
And best of luck! I had many failures before finding out what worked.
So what type of silicone is the red one?
The floppy red one is soma foama from smooth on. The more rigid and cleaner looking red foam parts are made of alumilite flexible foam.
Can you make a cigar mold out of plastic ??
I've never made a cigar mold and dont know much about them...
But if it's just a mold to shape cigars I dont see why you couldn't. Unless it was a complex geometry...I would still prefer to CNC it.
