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
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!
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.
Really interessting video! Also that you can just 3d print the molds is insane. Makes the whole process much cheaper than using metal. Genius!
Amazing, some time ago I have an idea to make injection molding using resin mold turns out you already make real working one. Awesome
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
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!
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 :)
Great videos on injecto 2.0 I love this machine!!
Cool stuff as always!
It’s cool to see injection molding machines making it to the consumer market. Good job!
That looks amazing!
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.
You have been making a lot of stuffs. Congratulations!!
How awesome!!! What a great video
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
Sounds like you need a modular rig for actuating the extraction pins. Then you'll be able to run the whole process faster
Why yes I would love an injecto 2.0!!
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 😃
Really cool device. Maybe I will build it in future
Love this idea
Those clear moulde are awesome !
Thanks 😅. Glad you enjoyed the video 😃
I'm a mechanical engineering student and I find your injection molding video's so fascinating. I love your video's!
Thank you 😃
Very nice! 😀
That machine INJEKTo 2.0 is awesome 🤩
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.
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.
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.
cool project
That's so cool
Where did you get the pellets?
Also, can you use abs filament as a substitute?
That's very impressive for such affordable tools
OMG I want this machine.
That’s awesome
this is amazing, injection molding is usually prohibitively expensive especially for high output of parts. The resin molds can revolutionize small scale injection molding
Very cool machine
Very Nice machine!
I would have so much fun using that. I love to design things for real world use, less than toys.
That’s cool with one of these imagine what you can create 😱
What was TH-cam thinking that I found this interesting.
Well TH-cam was right 😂
Looking good
Love your Videos 🥰, please make more interesting videos!
Very ccoool!!!
I realy want and need this machine 👍
Oh, I wish I had an Injekto 2.0. Good luck everybody .
O.O i need this tool!
very cool vid btw
Kid: Mom, can I have Lego?
Mom: We have Lego at home.
Lego at home:
Hahaha that’s hilarious 😂
thx man
What a nice idea
Thanks Julian 😃
Injecto 2.0 is soo cool nice work😎 I am currently studying Industrial design and really appreciate the simplicity and efficiency of your machine design. Keep up the great work cant wait for the next video💪
These videos are good like candy
What kind of plastic are you using ? Can you use hdpe to inject to this printed mold?
Thank you.
woozer!
Great concept
Thank you
@@ActionBOX I saw lot of DIY IMM but yours project is better.
This will be really cool way to reuse 3d printer supports
Great tool
Thanks 😊
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.
Awesome
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.
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.
Where do you get the energy to do such amazing things?
Cool
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.
Good video
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
Great video! Greetings from Argentina
Thanks Roberto 😃
Nice Video
You should add a leader to your lures. That way there's something to tie a fishing line to.
Thanks for the suggestion! 😄
Would this work for fishing baits as well?
Edit: Nvm. It was already covered lol
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 😂
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 😃
I need Injecto 2.0 :D
If I had this I will make America Great Again, that will be the truth 😃 thanks for sharing 🙏
Glad you liked the video.
Video idea: Try to build a shell of the mold only. Hollow, with the side facing the vice jaws open. Then fill it with some other cheaper material, like some two part resin or something. Maybe even with some filler to make it even cheaper.
This is a great idea. Thank you.
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.
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
This 2.0 looks really good.
Thanks 😃
Nice :)
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
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.
I am subscribed
Did you ever end up testing a mould without a vent channel? I was super looking forward to seeing you test that one bolt mould, but I watched the video twice and it seems like you gave up on the idea after changing the mould design to avoid warping in your vise.
Oh, and while I'm here, someone mentioned polishing the clear moulds to get a better view of the injection process. Speaking as someone who's spent a lot of time fiddling with ways to clarify 3D printed resin, I think polishing would be a waste of your time. The best method would be to design a number of small through-holes into the clear moulds so that you could just fasten them together with some long M3 machine screws that wouldn't obscure the faces that are already clear.
That said, if you *really* want to polish the other faces of the moulds, just sand them with some medium-coarse sandpaper (maybe 320 grit), wipe any dust and debris off with some 99% isopropyl alcohol, brush a layer of uncured resin onto one of the freshly-sanded faces, set it flat on the film at the bottom of an empty vat on one of your resin printers (being careful not to trap any bubbles), then do a full-bed UV exposure for a few seconds to cure the resin. Once you peel it off the bottom, you'll have a surface that's clearer and smoother than anything you could achieve with manual polishing, in a fraction of the time. Chamfer the edges with a bit of sandpaper, then repeat the process for all additional faces you want to smooth.
Whatever you do, I wish you the best of luck! Thanks for making once complicated and expensive manufacturing processes accessible to the rest of us!
I love your comment on how to make the sides clear. I will definitely do that. We tested the molds with no vent, those were the ones that overflowed significantly from the top. I’m glad you liked our video 😃. Cheers, Dave
@@ActionBOX Oh, got it! I was focused on how the vise pressure was causing the moulds to separate at the top, so I didn't realize that one of them was the un-vented mould. It might be interesting to try that again with a better-sealed mould, though you'd probably get a similar outcome.
Anyway, thank you very much for taking the time to read through my long comment and to answer my question! Cheers!
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
we need that machine at Argentina 100%
It would be cool with RUBBER LEGO BRICKS... really soft silicone type durometer...
You have to make a bionicle mask with this. Please, I'd love to see it
That would be pretty awesome! Haha
Hi from Iceland, I love your videos and hope win 🙏😃
Are you able to create a mold from resin on a resin printer? Am I understanding this right?
Yessir, and then use INJEKTO to fill the mold.
@@ActionBOX that's really cool I'm learning more about these methods and always assumes your mold bad to be made of metal due to the heat involved.

Very impressive. You mentioned that the 3d printed molds don't last too long. Could you specify roughly how many uses that equates to?
I would say around 20 injections. Hope that helps.
