We’re always trying to find ways to create teaching tools using our printers to show our material processes. So last week we made a quick illustrative video using a F2 printed Batman Bust from Thingiverse. First we made a quick silicone mold and then cast some clear polyurethane in to show how to deal with trapped air bubbles. You might notice a cameo of another releated item made with our materials that likes to pop up from time-to-time. Anyway, enjoy and let me know if you have any questions on the topic. https://bjbenterprises.com/index.php/wc-786-a-b/
Oh, and if you’re wondering why the frosted appearance vs a shiny clear… this is entirely dependent on the finish of the piece you molded off of. If we were to have painted a glossy clear coat over the model, the part would look more like a glass or ice sculpture. Having said that, a frosted finish reflects light much better and works good for this purpose.
