### PC-PBT (PBT Infused Polycarbonate)
PBT flaccifies the polycarbonate but preserves PC's strength and shatter resistance in the cold, making it one of the few cold-resistant filaments.
- Lower print temp
- Improved print quality
- Very low warping
- One of the easiest filaments to print in
### PMMA (Polymethylmethacrylate) ### PMMA (Polymethylmethacrylate)
Also known as acrylic plexiglass, the high transparency of PMMA is the only advantage it has over other polycarbonates for printing. Also known as acrylic plexiglass, the high transparency of PMMA is the only advantage it has over other polycarbonates for printing.
