Hello all!
For a while I have been wanting to make metal castings (aluminum in my case) for various projects I had in mind. Either as art projects or as practical parts and components to be used on various vehicles I have. And for a while I have been aware of the lost PLA casting method and a DIY built propane forge. That is, making a casting using a 3D printed model that gets melted away inside a traditional mold. Today's video is a recording of my very first attempt at producing a piece using this method plus a Plaster of Paris mold, as a greensand alternative. I have chosen commercial grade Plaster of Paris (the kind you can find at a big hardware and construction material store - the reason I did not use green sand is to attempt to do this on very easy to source materials) plus fine aquarium sand in a 50-50 ratio. The role of the sand is to add strength to the mold and prevent it from breaking. Which by the way, I am happy to say it did not happen - the mold did not crack even though it had to withstand two casting attempts (see in the video why). So, my casting attempt was done, it wasn't a complete success but it wasn't a failure either. In the end, it is a journey of discovery, and I do hope you will enjoy what I am about to share with you.
