Filament Polmask PETG PB01043 — Polyethylene Terephthalate Glycol (PETG) 1.75 mm, Black, 3 kg
Filament Polmask PETG PB01043 is a 3 kg spool of black PETG (Polyethylene Terephthalate Glycol) with a 1.75 mm diameter designed for FDM/FFF 3D printers. PETG balances printability and mechanical performance, offering better impact resistance and chemical stability than PLA while being easier to print than ABS. This makes it suitable for functional prototypes, mechanical parts and durable household items.
Polmask PETG delivers balanced mechanical properties, good layer adhesion and increased impact resistance compared with PLA, while remaining easier to print than ABS. The material also shows chemical stability suitable for many functional applications. A 3 kg spool provides a longer printing runtime for larger projects.
PETG is not as rigid as some engineering polymers and may not be ideal for parts that require very high heat resistance or extremely high stiffness. While easier to print than ABS, PETG can be prone to stringing and may require tuning of retraction and cooling settings to achieve optimal surface finish.
Load the 1.75 mm filament into your FDM/FFF printer and set the nozzle temperature to between 230 °C and 240 °C with the heated bed at 70–80 °C. Use a printing speed of 30–50 mm/s as a starting point and adjust based on print quality. For direct drive extruders start with a retraction distance of about 1 mm at 20 mm/s; for Bowden/indirect drive setups try 3 mm retraction at 40 mm/s. Enable a cooling fan for improved surface finish, reduce or disable it for stronger, more impact-resistant parts. If the filament has absorbed moisture, dry it at 65 °C for about 6 hours before printing.
For a compromise between surface finish and mechanical strength, try printing with 20% fan and the recommended temperatures. Use the lower retraction values for direct drive extruders and higher values for Bowden systems; adjust speeds within 30–50 mm/s to find the best balance for your printer and part geometry.
