トゲトゲをアルミ鋳造したら『こん棒』になりました【砂型鋳造】

I made a thorn mold with a 3D printer and cast it in aluminum. The wooden part is made from driftwood. A hole appeared in the middle of shaving the wood, and I almost broke my heart, but somehow I was able to repair it with wood glue and scraped wood. ○Sand casting method A sand mold uses two or several mold frames (called flasks) on the top and bottom.
