Compare 3d Printer Filaments – Side-by-Side Specs

Start with the manufacturer's recommended range—usually on the spool label or product page. PLA: 190-220°C (typically 210°C). PETG: 230-250°C (typically 240°C). ABS/ASA: 230-270°C. TPU: 220-235°C. Lower temps reduce stringing but may hurt layer adhesion; higher temps improve strength but increase stringing and oozing. Run a temperature tower to optimize for your printer and environment. Bed temps: PLA 60°C, PETG 80-90°C, ABS/ASA 90-110°C.

Stringing occurs when molten filament oozes during travel moves. Solutions: reduce print temperature (try 5-10°C lower), enable retraction (4-6mm for bowden, 1-2mm for direct drive), increase retraction speed (40-60mm/s), and enable coasting/wiping in your slicer. PETG strings more than PLA—it often needs lower temps and higher retraction. Dry your filament; wet filament strings badly. Slow down travel speed to give retraction time to work.

Warping is caused by uneven cooling and shrinkage. For PLA: ensure bed is level and clean, use 60°C bed, add a brim or raft. For PETG: 80-90°C bed, avoid cooling fan for first layers, use adhesive (hairspray, glue stick) if needed. For ABS/ASA: use an enclosure to maintain ambient temp, 90-110°C bed, avoid drafts. Enclosure is almost mandatory for ABS. Slower first layer speed and higher first layer temp also help.
