    I did the same thing you did with the molds the first time I did something similar to this.
    Change your mold to have a pinhole on the bottom. And then cover it with tape before you pour.
    When you're all done with your parts, pull the tape off and push the compressed air hose against the hole and you'll pop your part out.

      @johnblackwell5805 2 года назад +1

      That’s a great tip! I was thinking I’d make the mold thinner so it’s easier to smash(!) or submerge in hot water to soften the Mold but this air idea sounds much more elegant! 👍🏻

      You could also print the mold in PVA and then just dissolve it in water when you're ready to release your part.

      Having just ventured into this myself, I tried the Pin-hole method with little success and had a >50% demoulding success. Instead I introduced a 4mm Hole into the model on the base of the mold, tapped and used a pointed M5 Grub Screw with the point protruding into the bottom of the mould. With this i have a 100% Success rate with demolding.

    Great work! To be honest, this took a different turn than I thought it would. A buddy of mine got some "poly bushings" for his Toyota Starlet earlier this year, and they were 100% 3D printed, probably from TPU or similar. I could tell they were printed from the visual layer lines and print lines on the first and last layer. I figured you were gonna do the same, and watched to see what filament you used. But...I might actually prefer this method.

      I 3D print TPU bushes but not for suspension parts, just used for holding power steering pipes. I don’t think fully printed suspension bushes would be a good idea due to layer bonding. Yes TPU does bond well but it’s not 100% guaranteed to have a perfect bond.

    • @supergiantbubbles
      @supergiantbubbles 3 года назад +1

      I thought the same, that they'd be printed out of TPU. I think it would be worth a try. If a person has a direct drive printer and a high flow hotend (Sidewinder X1 for example) along with a large nozzle they could print a working bushing in a couple of hours at most. If I had a track car project I'd give it a try as I print a lot of TPU.

    I made some rear shock bushes for my car and although it was a very good outcome. After a few months one of them fell apart. I need to invest into a pressure pot to push all the bubbles out of the resin for it to hold up better. Even pouring slowly gave me bubbles with a 2 part mould.

    Those bushings looked good. You talked about a draft but I didn't see any. Don't worry about the draft and instead optimize your bushing shape. That mold is going into the garbage either way. Maybe a small arbor press would be faster than cutting them out. It's probably layer lines locking it in the mold, a light sand would take care of that. But all and all the end product looks good, costs much less than a commercial product and offers infinite customization. This is what I wanted the future to be.

    Since the polyurethane is just poured in at room temperature and not under any additional pressure, maybe you can adjust the mold design to have 8 vertical notches along the outer circumference like on the crust of a pizza pie after being sliced, and a ridge along the circumference of the bottom face, so that when you apply some pressure in the vice the mold just breaks at those points.
