Molding & Casting Small Urethane Resin Parts with two part silicone molds

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 really appreciate you showing the failed attempts because I'm currently struggling with a project and my fails are killing my motivation to keep trying. So, seeing a video where someone else is failing abit and still trying is inspiring.

Thank you for showing us when things go wrong. Because things do go wrong. It’s good to show that even professionals encounter issues so that beginners do not get discouraged when things go wrong.

I LOVE that you show the fails, it helps us so damn much in learning the process.

Legos are best for infinite mold boxes and are reusable.

Thank you once again Master for teaching your know-how, for showing possible mistakes and your desire to continue, showing that he who persists wins. A huge hug

I think it was Da Vinci who said that a true artist makes their own tools. Looking at what you have in your shop, you are a true artist sir.

Awesome. I liked you showing the failure part since we learn a lot from the work around.

Love your technique. Gave me some ideas I never thought of .

We’ll done! I’ve played your other videos on small part casting a million times. I’ve learned a ton from ya, thanks for making these videos!

I love this. Making mistakes is the key part of learning. I'm glad you are showing us your learning process. I fail all the time, learn from my mistakes, wipe my tears and try again.

Thank you for showing the hurdles!

Great tip for getting deep blacks

Very good, and great to see that it doesn't always work first time!

It is really valuable and nice that you add the mistakes you made in production to the video. Well done, you are doing a super job.

Again wonderful video Eric! That reaction between ckear and opaque silicon was similar to my problem trying to make fake polyester resin gems: never cured, always sticky

I've never seen this method of high pouring resin from an empty tube. Very interesting and I'll have to try it.

Really appreciate guys like you sharing the knowledge 🙏. I 3d print a lot.. I’m wondering what your views are from small scale perspective?… clearly there would be a lot of time in cad for me to replicate these parts and with potentially not the strength in a single cast product. Just really interesting your perspective and I’m so pleased I found this Real gem… the reality of yes some fail even with best intentions they still go boom pleased you kept them in 💯🙏👌🏻

I really appreciate the attention to detail and the workplace organisation, it shows a great deal of dedication to the art by having the workspace be very "purpose built" and not just stuff lying around.

your casting/ resin series rocks😃 I would like to see a version of your apple power adapter made in resin using your 3dp parts. thanks
