Prof. Lab PETG Grey 3 kg
Prof. Lab PETG Grey is a high-quality technical filament that combines the
strength and durability of ABS with the
printing comfort of PLA. Thanks to its grey shade, it is ideal for
prototypes, functional parts, mechanical components, holders, covers, and technical models where a professional neutral look without reflections is important.
PETG (polyethylene terephthalate glycol) material excels in
high toughness, low brittleness, and resistance to moisture and chemicals. Prof. Lab filament is manufactured with a
precise diameter tolerance of ±0.03 mm, which ensures
stable material flow and minimizes the risk of nozzle clogging or fluctuations in the extruded track width.
Main advantages of Prof. Lab PETG Grey
- Very good strength and toughness – suitable for stressed functional parts
- Excellent chemical and moisture resistance – ideal for parts in demanding environments
- Easy printing similar to PLA – prints well even on standard desktop 3D printers
- High winding quality and constant diameter – 1.75 mm diameter with ±0.03 mm tolerance
- Neutral grey color (Cool Gray shade) – suitable for technical prototypes and visually clean models
- Compatible with most FDM/FFF printers – standard spool and diameter
Recommended use
Prof. Lab PETG Grey 3 kg is especially suitable for:
- Functional mechanical parts, holders, grips, brackets
- Structural and functional prototypes
- Electronics covers, boxes, technical models
- Parts for outdoor use where higher resistance than PLA is required
- Components exposed to moisture or common chemicals (cleaning agents, etc.)
Thanks to the 3 kg packaging, the filament is also suitable for
long print jobs and series production, where continuous printing without frequent spool changes is a major advantage.
Printing parameters
- Filament diameter: 1.75 mm
- Diameter tolerance: ±0.03 mm
- Recommended nozzle temperature: 220–250 °C
- Recommended bed temperature: 95–110 °C
- Print bed: ideally heated, glass/PEI/buildplate with suitable adhesive
For optimal first layer adhesion, a
clean and degreased bed surface is recommended, and possibly the use of a suitable adhesive (glue stick, spray, special adhesive surface). For larger parts, a
brim or raft can help limit corner warping.
Compatibility
Prof. Lab PETG filament is compatible with most common FDM/FFF 3D printers that support PETG printing and a 1.75 mm filament diameter, for example:
- Creality, Prusa, Anycubic, Artillery, Ultimaker (with appropriate hotend), Ender, and others
Standard
spool with a diameter of approx. 195 mm and a 75 mm hole is suitable for most spool holders.
Logistics and packaging
- Filament weight: 3 kg
- Material: PETG (polyethylene terephthalate glycol)
- Manufacturer: Imagine s.c., brand Prof. Lab
- The filament is usually delivered in a sealed protective package; storage in a dry place is recommended – ideally in a resealable bag with desiccant.
