PCTG is an excellent alternative if you're looking for a filament with PET-G properties, but with increased impact strength. Printing temperature 250-270°C, bed temperature 90-110°C.
PolyTerra™ PLA and PolyTerra™ PLA+ are based on the same eco-friendly formula however PLA+ was optimized for better layer adhesion and overall strength. Printing temperature ranges from 190 °C to 230 °C (25-60°C for build plate).
