3D Printed Molds for Casting 3D Prints!

Let's see if we can make our own 3D Printed Mold Boxes that we can pour silicone into for casting or melting 3D Prints!

This is so dang cool!!! Probably the easiest and most useful way of reusing PLA so far. 👌

The rice trick isn't for checking weight, it's for checking volume. Airsoft BBs are better media for that technique because they won't get rice dust in your molds.

Just a heads up.. If you print your molds from RESIN they will prevent the silicone from curing at the surface that contacts the mold and you'll have a sticky mess. Resin printed molds will need to be primed and painted and mold released.

This is so cool and inspiring! Love it!

I've been doing this same process for my products for the past couple of years. It's helped me prototype a lot of stuff for both myself and my clients.

[Alex-wlsp]

I think the coolest part of this process is that after you make the silicone mold, the mold box becomes another old print that you can melt down to make things.

I'm excited that you're getting into casting. Such fun!

[cocvhecv]

I love the idea of using filament scraps. Great job.

[masterarselyn]

This was enlightening, thank you for that. I was looking around wondering how to do that for candle molds and now i know a bit more, thanks

[Vko______]

Great video! Love your energy, I was literally smiling when you were demolding! haha what a success.

[barbarafidler]

best video so far, thanks for the information

Have you tried preheating the silicone moulds? It might encourage faster surface contact melting & lower the number of voids

[Zeldur]

For the molds, Punished Props is also a great resource. Also, Smooth-on goes into detail on of their different products. I know they have one that's for high temps like molten aluminum.

While these are melting, maybe try using a hot air gun to heat up the most exterior most print scraps to prevent the pockets? I'm excited to see more experiments using this method

I came up with the idea (not saying I originated it) of building a box abound my designs some years ago in order to pour silicon molds. However, I wasn’t planning on pouring plastic into the silicon molds but rather melted chocolate. Other candies may have worked too. The important thing being that if food is involved your silicon has to be specifically food safe. I also used the walled technique to create molds for chocolate using cookie presses as the positives for the mold.

This is 🔥- my inner child is going nuts right now❤ Happy new year

[rezincreative]

I love the idea of making molds. I ordered some Smooth-On also and didn’t realize how short the life span was. Never got around to it because of it solidified. It’s not cheap either.

[cleio]

Very cool idea. Love mold making from 3d prints. You may need to melt the PLA bits into a liquid or semi liquid before putting them in the mold to avoid the little bubbles. or perhaps heat them in a low temp kiln to ensure completely even heating, im not sure how even that little oven would heat something considering the heating coils are usually on top or on bottom.
Can't wait to see more.

I've thought of this awhile back, procrastination and work kept me from trying it out. Glad to know the concept works in practice. Now if I get around to it, casting one of my prints in tin. Some silicone can survive high temperatures.

[tamsinp]

Just a thought for avoiding the divots - rather than filling the moulds completely, just put a little bit in at a time, let it melt, add some more, let it melt, rinse & repeat until the mould is full and all the plastic has melted.

[williampflugfelder]

I'd like to see more of these. Thanks
