I love PolyCast, and have achieved great results making musical instrument components, which require an exceptional degree of precision, up to +/- two thousandths of an inch in key areas. However, a significant drawback of the material is that layer lines within the part viewed through a polished exterior, and layer lines not yet removed, are visually indistinguishable even under strong magnification.
As I wrote in my idea submission, I acknowledge management of ash production is key for a castable filament, but a properly vented kiln will have oxygenation sufficient to completely oxidize a pigment such as pure carbon black. Especially when working with complex parts or high tolerance applications, technology like the Polysher simply cannot maintain sufficient dimensional accuracy and completely remove layer lines.
Preparation of the part by hand while it is still plastic is essential for cost efficiency when working with complex assemblies or hard final materials like aluminum bronze.
I feel this simple and cheap addition of carbon black or a similar pigment would strongly enhance the user experience of PolyCast for jewelers, modelmakers, instrument makers, and high-tolerance applications.
