This was a test I made to see how viable lost PLA casting is and at what resolution would I need to print at. These PLA prints were not cast in wax but rather vested and burnt out directly. This saves on a lot fo time and money although the print being cast needs to be perfect.
From left to right is a .04mm print, .06mm print and a .1mm print. The .06mm and .1mm prints have clear resoltion lines in the final bronze.
You can see some of the original prints at .06mm and .1mm. The striations are still visible in the bronzes. Only the .04mm prints seems to be fine enough not to need any clean up.
