    Nice work again Eric. Showing the fails with the success is something missing in many of the tutorials out there. It's a great way to learn how and why things go wrong, and how to avoid it again in the future. An interesting thing we've found with WC-85DM rigid clear polyurethane when it comes to moisture sensitivity; you can avoid moisture bubbles if you cast into a heated mold (around 120F/50C) at ambient pressure (no pressure tank) OR simply pressure cast it. You got the benefit of both by pressure casting with heat, so you can create bubble-free parts faster and with much better "green strength" upon demold compared to a room-temp cure. Keep up the good work!

    I did this for a few years. We made a lot of toys as well as some pieces for the Keurig coffee machines. Worst mistake i ever had happen was while pouring a few Chewbacca figures for Hasbro, the resin we used was mislabeled and instead of part a mixing with part B, the same material was in both 5 gallon containers. The next morning, after opening all the pressure pots, i opened up the first mold to find thick gooey resin pouring everywhere. And it took forever to clean all those molds. Chewbacca has a lot of hairlike features that creates a LOT of area to wash out!!!!

    Thank you for such an informative video on casting such small parts, including the issues you've found. I really need to make parts roughly the same size, if not smaller. Do you think it would be possible to do this without the pressure/temperature chamber that you used on your video? If so, would there be any problems I might face not using it. (some of my parts will be roughly 2mm thickness.) again, thank you for a great video.

    Interesting use of golf tees to use as a sprue and venting holes. For the pouring vent, definitely use an actual funnel so it will be less mess and the pour sprue will be easier to remove.
    The funnel shank should be the same diameter as the cental shank of the tee

    Interesting stuff. But I can't help but think that it would have been easier to design and resin 3D print. Still, incredibly informative video. Cheers mate.
    Having said that, I have absolutely no idea what 120 degrees Fahrenheit is in centigrade.

    Hello
    when you making 3 d print and after you do silicone form -what you use for smooth the surface?
    did you paint or what can yse ,because lot of matarials is reacting with silicone and not dry

      Most places that sell resin will sell colorant as well. But the so strong colors from smooth on have been decent, but there are many pigment supplies out there. Just make sure it's alcohol-based

    Why do you degas the silicone befor pouring? couldn't you degas it in the mold? same for the resin. thanks for your content!

    • @EricStrebel
      @EricStrebel  Před rokem

      Good question, you wouldn't do yes the silicone because you could ruin your master, and you wouldn't degass your resin once it's in the mold because you wouldn't get a good part and you could easily trap bubbles.

    I think you could have released the ring from the first mold. Next time try shooting some compressed air inbetween the silicone and the part to break the seal. If that doesn't work, I would have carved out of the a cone/core from the center of the ring. This would have allowed more room for the ID silicone to be pinched and flex which should have given enough wiggle room to remove the part.

    Eric, have you ever had an experience with uneven shrinkage of polyurethane? How do you get over it?

    • @EricStrebel
      @EricStrebel  Před 2 lety

      No, use good PU

    • @bjbenterprises
      @bjbenterprises Před 2 lety +3

      Sometimes uneven shrinkage can come from a lack of vents and "make-up material" in those vents as the material cures and tries to shrink. The vents work in two ways, they channel air out of the mold as the mold fills with urethane, but then those columns of material act as small reservoirs to feed the curing part. That's why fill ports are often sucked in after the part is cured. You want those vents to be roughly similar size to the wall thickness of the part so they don't exotherm too quick and starve the part from make-up material. If you have a very thick walled cast part, you need to make sure there are plenty of vents to avoid this issue or you'll end up with sink-back marks on the part or what we call "worm wood" marks.
