In this video I experimented the first time with lost PLA metal casting, I used as always recycled aluminum scrap for this project, I created in the past x2 3d printings using photogrammetry method of two statues, since then I created various sizes of the statues 3d printings but always wanted to have them from a more solid material. I decided to make an experiment with four hollow 3d printed patterns, x2 in 2mm shell thickness and x2 in 1mm shell thickness. My assumption was correct where the two 2mm aluminum casting failed and the other two in 1mm turned out much more successful.
