Print Settings Guide for Prusament PETG
PETG requires slightly more dialing than PLA but rewards patience with strong, semi-flexible parts. Set your nozzle to 230-250°C — PETG needs heat to bond properly. Bed at 85°C with a PEI or glass surface; avoid smooth glass without adhesive as PETG can fuse to it permanently. Use 50-75% fan cooling — PETG benefits from some cooling but too much weakens layer adhesion. Print speed of 50 mm/s is a good baseline. PETG is prone to stringing; increase retraction to 5–7mm (Bowden) or 3–5mm (direct). First layer: slow down to 20–25 mm/s and set your Z-offset slightly higher than PLA to avoid the nozzle sticking to the layer.
Why Choose Prusament PETG
Prusament PETG sits in the sweet spot between PLA printability and ABS mechanical strength. Prusament PETG is formulated to minimize the notorious stringing tendency of glycol-modified PET while maintaining good inter-layer bonding. Heat resistance up to 80°C makes it viable for parts that live in warm environments — dashboards, outdoor fixtures, and mechanical housings. The semi-flexible nature prevents brittle fracture under impact. Community feedback on PETG from respected brands consistently calls out dimensional accuracy and consistent melt flow index as key differentiators between good and mediocre PETG.
What to Print with Prusament PETG
Prusament PETG is the go-to for functional mechanical parts: hinges, clips, brackets, enclosure panels, and snap-fit assemblies that need to survive real use. Food-safe when printed through a clean, uncoated brass nozzle with 100% infill (no dyes in contact layers). Outdoor fixtures, drone frames, and camera mounts benefit from PETG's UV and moisture resistance compared to PLA. Water-tight vessels are achievable with 4+ perimeters and high infill. Replace any PLA part that lives in a car, near a heater, or outdoors with PETG — heat deflection at 80°C vs 60°C makes a meaningful difference.
Common Issues & Fixes
Stringing: most common PETG complaint — raise retraction, lower temp 5°C, increase travel speed. Bed adhesion too good (part fuses): apply glue stick or hairspray as release agent on glass. Layer splitting: increase temp 5–10°C or slow down. Blobbing at seam: enable seam hiding, use linear advance. Z-banding: mechanical issue, not filament. Moisture absorption: dry at 65°C for 4–6 hours if prints look rough or have bubbles.
Notes
Lower speeds reduce stringing. Dry before printing if humid.
