Polyurethane Casting

Ғылым және технология

This is my first attempt at casting a 3D printed part in resin. In the end I think I used a bit too much silicone for the mould, however I still have enough to make several more in the future. I will also try to pre-mould the alignment keys to prevent some of the flashing forming around the seam line.
Please note that this is not an instructional video. If you want a very good tutorial for casting, I recommend these two videos by BJB Enterprises:

The silicone and polyurethane I am using came from polycraft.

    Alot of mold for small part. Instead of tape. Hobby store or walmart has rubber bands. Easier helpful Instead of funnel. Can use injector. Like off a food injector. Once you inject resin. Can suck up rubbing alcohol for cleaning it. I got some goof off residue remover. Gonna see how good it cleans it. I recently got a pressure pot. For removing air bubbles. Hope this helps

    You could have made 4 moulds from that amount of silicone… :D Also if you have parts with a flat surface, you can just make it an open mould - then sand to flatten perfectly.

    Since this was my first mould, I wasn't sure how much silicone was needed. The second version I made used about 1/6 the amount of silicone.

    No worries, happened to me too :-) I also highly recommend some pigments. I use nail supplies from Aliexpress - they got some cool stuff, like thermochromic and all sorts of neon.

    Yes, but it's much cheaper and faster in the long term compared to 3D printing. There are also no layer lines.

    Do you need to use a lot of silicols for a small cast?

  • @Ryzler13

    Such a small part, so much silicone and resin. You could make 3 moulds and 3 parts with all that.

    I used cling film to hold mould together, and a large volume syringe for injecting the resin.

    It tilts the mould so that there is a low point and a high point. It is best to fill with resin from the low point and vent the air from the high points to improve material flow and reduce air bubbles.

    Yes. When casting things in clear it's best to put the resin in a vacuum chamber or pressure chamber to remove any bubbles that make it look cloudy. With opaque parts like these a vacuum isn't really necessary, especially since the viscosity is so low.
