Yes it could be done, in injection industrie is common to add fillers to your mixture, this could be chalk, fiberglass, carbon fiber, this is usually done to improve stifness or heat resistance

No it can't. It'll be able too, but for specialized pellets you need specialized equipment, to ensure longevity. All sort of fibers in this process would act like abrasives, both in the machine and in the mold. My job is making molds, running sims and choosing the appropriate machine for the job. The other comment is wrong, while fibers are used, it's very rare, for the exact reasons i just listed. In 99,99% of all cases we're able to just use a different plastic that has the properties we need for that specific job. BTW I've never heard about chalk or any filler, plastic pellets is very cheap, mixing it with a filler just end up costing way more. As a rule of thumb, at least 10 new plastics are invented everyday. If you can't find the plastic that has the properties you need, you probably haven't looked close enough

hypothetically could it handle using Carbon nylon filament cut up into pellets? I mean hobbyist 3d printers handle it with a steel nozzle so I assumed a mostly steel injection machine would as well. I'm not trying to say reinvent the wheel or make a mixture of carbon fibers and normal pellets or make a new custom material. @@VikingRul3s

@@jordanhorst6 Well i'm off today, so guess i'll write you a rough guide. So, it'll be able too, but it's a matter of how many before your mold get bad, which will be the weakest link by far. Let's split it up. Machine: An injection machine runs with very high pressure and the internals is vastly different then a 3d printer. It would be easier to just search for how they are build up to understand how much more need to be a special alloyed hardened steel. It's possible to DIY harden steel, but the parts need to be uniformly heated (extreme difficult DIY) and if it turns out that a special alloy is needed (as i would expect) is practically impossible DIY and you would then need to hire a company specialized in hardening. Mold: Now that you have your machine upgraded to your needs, you'll need a proper mold, to ensure accuracy. This means getting a mold CNC milled, then surface hardening by hardening company and after either DIY polished or hire a mold polish company. This is not nearly as expensive as upgrading the machine. A mold like the one in the video, made properly (cause even in plastic video poster did a very poor job) will cost north of 2000$ for an very basic mold Sum: Now you're good to go, you'll now be able to create a lot of accurate products. This is a very cheap setup, i'm guessing the total price will be less then 30.000$. Longevity is still an issue, but you're now in the 10.000-50.000 per renovation (mold need more frequent checks, machine renovation will be far apart, at least 25.000, likely over 100.000). The downside is that is you don't spend on all the upgrades, regular steel will fail fast, meaning the internals of the machine will fail very fast. So while it'll be able work with carbon fiber plastics, your "per product cost" will be high and unstable enough that it could sky rocket compared to your estimates, meaning you'll have sold the products to cheap and first realize it when you machine is broken down Keep in mind that an injection machine opens the door to literally 1000x more materials then we can use in cheap 3D printers. It's extremely likely that you can find a material with the right properties for such a machine and thereby completely avoid the upgrades (you'll likely still need a proper steel mold) Happy development

​@@VikingRul3sI have a question for you. I have some parts made from glass fiber reinforced polypropylene. I commonly end up with ones which have broken mounting tabs. When I have both pieces, I can melt them back together with a soldering iron, using the same material for filler, and it seems to be as strong as one which wasn't broken. I've often wondered if I could make a mold which would go over the remaining part of the mounting tab and inject new GF-PP to replace what is missing. Would the new plastic melt into the existing plastic, or would it just form a cold joint which would break easily?

20 is far optimistic 😅

layer adhesion issues

Thanks 😃

Per the spec sheet on their website, the maximum injection volume is 44 mL. Not very many at once…

Same cost as about 80,000 golf tees xD

He already did it dumbo jumbo
