Accordingly, if you are going to use injection molding for your production, you should also try to find ways to use injection molding in your prototyping.

@@juriaan5786 yep your right, 3D printing fills a gap for sure. I actually run a farm making rapid prototyping types for 4 local businesses. Nearly all the parts are pla as they mostly are testing cad designed parts on equipment before they move to another step in producing the part. Sometimes I’ll make 8-10 revised parts before they get everything right. Rarely I’ll be asked to resin print something but it has happened. But I think the ability to test an injection mold is a huge money savings and a game changer, and for limited production small run parts likely far far cheaper then ever making any tooling. I used to work in plastics, and worked in a mold shop in a thermoforming factory. That company brought mold making in house due to the expense. I’ll bet at this point they have 3D printers to do prototyping and some testing.

If your parts will be produced by injection molding, it is great to have a prototype tooling platform that provides the benefits of 3D printing (mainly low start-up costs, short lead-times and design freedom)

This is really interesting because some manufacturers might never scale beyond 500 or 1,000 parts threshold where a $20K tool would start to make sense, but it's more interesting that the technology makes it possible to injection mode single piece parts that would be impossible with any other technology. That said, thee $6 per part tooling is not including the cost of chemicals or the disposal of the dissolved resins. Also, he mentions machining being wasteful, but the environmental impact of machining depends completely on the source of the energy. I think the environmental aspect of the technology is being overstated a bit.

I would, however, invite you to consider how soluble inserts might substitute mold action (sliders, collapsible cores etc.) in a conventional metal tool. Key benefit of this approach is that you reduce investments in metal tooling (by eliminating the action) while at the same time reducing unit costs (by reducing the size of the parts to be printed). We see manufacturers use this approach as they scale from the prototyping to the small-volume production. Let me know if you'd be interested in hearing more.

Metal chips from machining are completely recyclable by processes well over a century old. BTW if the resins can be combined with another chemical to make the end product inert that would solve the disposal problem much as painting a disposable surface produces an inert (as far as HazMat regs are concerned) result with many paints.

This also eliminates storage space for the molds. Often the manufacturer has a store house to hold the molds when not in use. Often customers will run a batch of say 10k parts maybe 2x per year so when not in a batxh run, you must store those molds. Mind you, now you need to occupy some of that reserved space with the dissolve bath now but much smaller space required. The avility to remove the limitations of the mold design is huge. Much more complex single parts can be made now. Awesome win!

That is actually pretty amazing. I've seen how expensive molds for injection are and multi part molds even far more expensive.

This is very useful for small scale testing of turbines and propellers. You can makes changes to the design, and have a new part the next day. Where as the prep and running of a CFD simulation can take much longer. Also unlike normal 3d printing you can use plastics that just aren't possible with filaments, that is a huge thing for low volume parts with complex geometry. Like custom sized medical implants. Just like the powdered metal 3d printers improved knee and hip replacements.

Yes, but these would also work with the injection molding resins of other manufacturers. The key here is that you are not limited by the mold geometry.

You know, injection molding and 3D printing actually have a lot in common, and it gives me an idea... What if you could make a 3D printer, that doubled as an injection molding machine, and could print it's own injection molds? Like all you do in injection molding is you heat plastic and inject it as a liquid into a mold. And with 3D printing you heat plastic and deposit it on a build plate. If you 3D printed a mold with a high temperature PLA, and then had a second higher pressure extruder inject it with a lower temperature plastic, then boom, 3D printing and injection molding combined into one.

This is super cool, but I wonder what the limit of interior cavities is? I don’t imagine it comes up that often, but if for example, you want to reduce material use to lighten apart, and therefore you want to have a cavity inside, one imagines that the system would be appropriate for that. I guess what I’m asking is, what are the limitations of the type of objects you can make with this, and how does the system help you prevent creating parts that will not have the dissolvable materials stuck inside?

This is an industry changer.

We are also pretty fascinated by the need for spare parts on demand that surfaced as supply chains started falling apart during the Covid. It appears to be easier to qualify a spare part made in the original material, and w. the original process :-)

This and the comments here scratches only the surface of the possibilities, we machine hydraulic seals out of full materials with CNC lathes if they aren't standard size. Even at 10K piece that is cheaper than a new mold. If you can make a cheap mold that can last 1000 pcs it would be amazing as cnc cutting 10K is a lot work.

I absolutely agree, @psxtuneservice - we are only scratching the surface still. And the integration of CNC into the toolchain of Freeform Injection Molding is one of the things I am looking forward to exploring more as it may help us lower costs and speed up work further.

Linus will be mad when he sees this video. Bro THIS is the stuff.

Could the plastic mould handle the 350 to 400 Celsius needed to injection mold PEEK?

Absolutely, @ZacDolenc.

Where can I invest? O.o

What ultimately becomes of all that dissolved plastic?

Depends on local regulations. We treat it as standard industrial waste to ensure that the waste stream is controlled.
