Ceramic materials offer a variety of desirable material properties, but due to being particularly hard and brittle, are challenging to machine in subtractive processes. Additive manufacturing of ceramics parts requires costly machines and raw materials, limiting the use of additively produced ceramic parts to the professional realm. Fused Filament Fabrication (FFF) has become a widespread additive manufacturing technology, due to low cost of machines and materials (typically polylactic acid (PLA) and ABS)).
