Lid (80/60 mm) With Pouring Basin For Lost Wax Casting

thingiverse

I had to recreate VegOilGuys design because my flask is smaller. I use one with 80 mm diameter - and I wanted to use it for lost-wax-casting with a wax sprue. You can use 9 mm sprues for example those that were casted with my mold. https://www.thingiverse.com/thing:4082778 I first printed the lid from PLA, but it didn't work out as I had hoped. It tore apart when I tried to remove it from the plaster. Maybe a release agent would have helped in this situation. Instead, I printed the next one out of TPU (flexible) and it worked great. Yesterday, I successfully completed my first lost wax casting and it turned out well for me. The only issue was that the plaster had some cracks. To improve this process or find a better investment plaster is now on my to-do list. I would like to take this opportunity to thank VegOilGuy! I built a vacuum-chamber following his video and discovered many more helpful tips on his channel: https://www.youtube.com/channel/UCkEYj8wtK3aEW8vSGhlB43g To enhance the effect of the vacuum, you could use the Straw Technique as described by VOG here: https://www.youtube.com/watch?v=5GkLZynNvNs I utilize a Flask-Liner - also based on a thing by VegOilGuy: https://www.thingiverse.com/thing:4132885 I made it customizable for different flask-sizes. UPDATE: I added a version for a smaller flask (60.3 mm) and the freecad-file.
