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.

Advantages

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.

Suitable for

• Functional prototypes and mechanical parts
• Household items and fixtures requiring impact resistance
• FDM/FFF printers using 1.75 mm filament
• Models where a balance between printability and durability is needed

When it may not be suitable

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.

Key specifications

• Material: Polyethylene Terephthalate Glycol (PETG)
• Colour: Black
• Diameter: 1.75 mm
• Spool weight: 3 kg
• Recommended printing temperature: 230–240 °C
• Recommended bed temperature: 70–80 °C
• Typical printing speed: 30–50 mm/s
• Fan: 0–20% depending on desired surface finish vs. strength
• Drying (if moist): 65 °C for 6 hours

How to use

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.

What to consider before purchase

• Confirm your printer supports 1.75 mm filament and can reach the recommended temperatures
• Consider whether you need low flex (stiffer) material or a balanced strong/printable material like PETG
• Plan for possible tuning of retraction and fan settings to minimise stringing
• Store filament dry and sealed to avoid moisture absorption

Usage recommendations

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.
