Product description
Filamentree PETG Matt-7 Jet Black 1kg
Filamentree PETG Matt-7 Jet Black is a highly stiff, matte PETG filament developed for technical and functional prints where strength, precision, and professional appearance are key. The matte jet-black shade hides layers, looks very elegant, and is ideal for housings, technical components, and design models.
Matt-7 Material Characteristics
The number “7” in the name Matt-7 indicates the level of brittleness on the manufacturer's internal scale from 1 to 10 (1 = very flexible, 10 = very brittle). A value of 7 means higher stiffness and hardness than standard PETG, with minimal elongation. This ensures:
- High dimensional stability – parts hold their shape better and do not deform
- Minimal flexibility – suitable for precise mechanical components
- Professional matte surface – reduces reflections and helps hide layers
Main Advantages
- Matte Jet Black surface – deep, rich black color with a modern matte effect
- Stiff and strong PETG – suitable for functional technical parts
- Excellent layer adhesion – lower risk of delamination even for taller models
- Resistance to chemicals and moisture – suitable for parts in more demanding environments
- Good heat resistance (up to approx. 80 °C) – usable where PLA would not suffice
- Stable diameter with tolerance < 0,03 mm – reliable performance even on more sensitive extruders
Recommended Use
This filament is ideal for:
- Technical and functional components – brackets, mounts, assembly elements, structural parts
- Electronics housings and enclosures – where both appearance and mechanical resistance are important
- Presentation and design prototypes – clean matte surface without distracting reflections
- Jigs and fixtures – workshop aids, assembly / auxiliary tools
Printing Recommendations
| Parameter | Recommended value* |
|---|---|
| Nozzle temperature | 230–240 °C |
| Bed temperature | 60–70 °C |
| Printing speed | 40–300 mm/s (depending on printer) |
| Fan | low to medium power |
| Closed chamber | not necessary, but helps stability |
*Specific settings may vary depending on the printer and conditions. For best results, we recommend performing flow and temperature calibrations and starting at lower speeds in the range of 40–80 mm/s.
