PolyCast Synthetic Investment Casting Wax
PolyCast is an excellent synthetic investment casting wax filament that can be 3D printed. Detail reproduction is good for most applications. Casters report that for thick section parts some ash occasionally remains otherwise they say it integrates well into their investment process. Alcohol sealing often smooths or rounds the edges of details.
