Lost PLA Casting - An Introduction
What is Lost PLA Casting?
In the latter part of 2018 I was happily trying to teach myself the ancient art of Lost Wax Casting, but in early 2019 something happened to change my casting focus - I bought a 3D Printer. I'd long since heard of Lost PLA Casting, but now I had a means of trying it.
For those not aware, with Lost PLA Casting, an item is printed in PLA filament. This is then set inside casting plaster (much as with Lost Wax Casting). The PLA is then melted away to leave a void the exact same size and shape as the original print. Molten metal is then poured into this void and a metal shape created. So the PLA is "Lost" - it's burned away - hence the name.
