- How to use a 3D Printed Injection mold for high volume production!
Step 1: Print the mold in a material with a higher melting temperature than the plastic you are intending to manufacture. I used PCTG here and it works great.
Step 2: Weigh out your filament. This mold uses exactly 6 grams of plastic. I used purge filament which provided a cool effect.
Step 3: Melt down your filament into a pliable material. I used PLA and set my oven to 450°F which is around 230°C. During this step you’ll want to manipulate the plastic into a shape that can fit in your mold. You should use metal tweezers or pliers.
Disclaimer: Wear proper PPE and perform at your own risk. Inhaling fumes probably isn’t good for you and you’ll dealing with hot materials. Be careful!
Step 4: Quickly use your tools to remove the plastic from the oven and into the mold.
Step 5: Squeeze the mold as tight as you can. Let cool, remove the mold, and you’ll have your item!

That is more of a compression mold, not injection
Not me waiting for him to inject the plastic... ;-;
Works surprisingly well... Try adding mold release or some some vaseline on the mold for a much easier removal.
What is a very good idea for home recycling, at least better than in some waste sorting. Personally, I have already made more of them and I would like to give you some tips on how to make your work easier. First of all, it is good to print the form to the lowest possible layer height, then the product does not stick as much in the form. In addition, I use cooking oil. It helps a lot to release the products. cool the mold in cold water, for example, and the last idea I used filament pla ht 110 and thanks to this I can also recycle PETG without it sticking, this material can withstand a higher temperature than PETG, in any case, I am very happy for this way of recycling and as soon as I fine-tune the production process, I will start with other forms
Co to je velice dobrý nápad na domácí recyklaci aspoň lepší než v nějaké třídění odpadu. Já osobně už jsem jich udělal víc a rád bych vám tedy dal nějaké tipy jak si ulehčit práci za prvé je dobré tisknout formu na co nejnižší výšku vrstvy pak se výrobek nedrží tolik ve formě navíc používám olej na vaření velice pomáhá vydání výrobků další je dobré nechat formu ochladit třeba ve studené vodě a poslední nápad použil jsem filament pla ht 110 a díky tomu mohu recyklovat i PETG aniž by se prilepilo tento materiál vydrží větší teplotu než PETG každopádně jsem moc rád za tuto cestu recyklace a jakmile doladím výrobní postup pustím se do dalších forem
Use a jacking screw to force the part out.
very cool
Very interesting
Thank you for confirming this works. I have a CNC Mill on its way from China... and I was thinking about doing this exact same thing with PLA and a machined mold.
No problem thanks for watching.
Broke my first file like that when i was a kid. Never use them that way since.
Yes, they're hardened and brittle
I cut my finger the first time I tried to cut a pumpkin. I never tried it the same way again 😅
Definitely try using a release agent so the parts can come apart easy. I think just basic Vaseline would work well.
Interested in how you calculated or designed the mold for precisely 6 grams of PLA?
No idea how the designer did it, I just found it on MakerWorld and printed it makerworld.com/en/models/437241?from=search#profileId-342435
For melting that small amount of PLA sure a heat gun would be quicker and more efficient?
Probably but it will take longer
Injection?
Have you tried injecting the filament straight from the extruder?
I have not but I feel like that would take a while
Can you tell us where you got the file for the mold?
... do you know how boolean in cad works?
@@wchodala9263 do you know how tolerance works?
Right here! makerworld.com/en/models/437241?from=search#profileId-342435
Just wish 3D printing was better at doing shallow slopes..oh well, this obviously isn't the only use for this concept :p
lower the layer height, you'll still get steps but less visible
@@bastv2417 I was thinking more than non-planar thing, but even that isn't perfect..
Depending on the geometry you could also sand the molds. Or print in something like ABS/ASA and then smooth it.
how did you calculate 6 grams of PLA?
The model instructions told me how much to weigh. Here's the STL I downloaded. makerworld.com/en/models/437241?from=search#profileId-342435
