Metal Casting


Recently I’ve become interested in metal casting 3D printed objects.

After some research I decided to use Grant Thompson’s Mini metal foundry design and make my own. It’s powered by charcoal or in my case BBQ briquettes which seemed to do the job.

After my first attempt the foundry appeared to be hot enough I was able to briefly melt some aluminium cans until the bottom of my recycled crucible made out of a old fire extinguisher started to melt and eventually gave way followed by a short bust of sparks.

To solve this problem I was be investing in a graphite crucible to insure success whilst smelting aluminium for casting.
