Polymaker PB01057 PETG Filament 1.75 mm 1 kg Dark Purple High Toughness Heat Resistant

Printing with standard PETG can be a challenge—warping, poor layer adhesion, and brittleness often ruin functional parts. Polymaker PB01057 PETG filament solves these issues with a formulation that delivers high toughness, heat resistance, and excellent layer bonding, making it ideal for durable, end-use components.

Who is it for

This filament is for makers, engineers, and professionals who need strong, heat-resistant parts for automotive, mechanical, or outdoor applications. It works with any FDM 3D printer that accepts 1.75 mm filament.

Main features

• High toughness and impact strength – withstands stress without cracking
• Heat resistant – can handle temperatures up to 65 °C under load
• Excellent layer adhesion – reduces delamination for stronger prints
• Low warp – prints reliably on standard build plates
• Consistent diameter – ±0.03 mm tolerance for smooth extrusion
