Hight quality PETG 3D-Printer Filament Material in 2.85mm
PETG Filament 2.85 mm – Durability for Ultimaker & Co.
Our 2.85 mm PETG Filament combines the ease of printing of PLA with the durability of ABS. It is specifically optimized for 3D printers with 2.85 mm / 3.00 mm extruder systems (such as Ultimaker, BCN3D, LulzBot). PETG (Polyethylene Terephthalate Glycol) is the ideal material for functional parts that are mechanically stressed and require a certain degree of flexibility.
Why PETG in 2.85 mm Format?
The diameter of 2.85 mm is particularly advantageous for Bowden extruders when printing with PETG. Since PETG is slightly more flexible than PLA, the thicker diameter prevents unwanted compression or buckling inside the guide tube. This ensures extremely precise retraction and reduces the "stringing" often associated with PETG.
- High Impact Resistance: Does not break as easily as PLA or acrylic.
- Temperature Resistant: Dimensionally stable up to approx. 75 °C (ideal for technical parts).
- Chemical Resistant: Resistant to many oils, greases, and alcohols.
- Excellent Layer Adhesion: Parts are watertight and very stable.
- Low Warping: Minimal warping, much easier to print than ABS.
Technical Processing Instructions
PETG 2.85 mm is excellent to process but requires slightly higher temperatures than PLA. A clean "retract" setting is important to avoid stringing. The material adheres very strongly to the print bed (often too strongly on glass/PEI), so a release agent (glue stick or hairspray) is recommended.
Recommended Parameters (Z3D PETG 2.85 mm)
- Hotend Temperature: 230 °C – 250 °C (requires more heat to melt)
- Print Bed: 70 °C – 85 °C (heated bed recommended)
- Cooling: Part fan at 20 % – 50 % (too much cooling weakens layer adhesion)
- Print Speed: 30 – 60 mm/s (PETG prefers slower speeds compared to PLA)
Applications for 2.85 mm PETG
- Mechanical functional parts (gears, brackets, snap-fits).
- Housings for electronics (heat resistance).
- Watertight containers and vases.
- Outdoor applications (more weather-resistant than PLA).
- Transparent objects (Natural PETG is very translucent).
PETG vs. PLA – The Difference
While PLA is very stiff and hard, PETG offers higher toughness. It yields slightly under load before breaking, making it indispensable for mechanical parts. Additionally, it withstands temperatures (e.g., inside a car in summer) where PLA would already start to soften.
