Prof. Lab PETG Grey 5 kg

Prof. Lab PETG Grey 5 kg – high-capacity grey PETG for long and reliable prints

Prof. Lab PETG Grey 5 kg is a high-quality PETG filament in a neutral grey color, designed for long print jobs and small serial production without interruptions. Thanks to the large 5kg spool, it significantly reduces the number of filament changes, which is ideal for 3D printer farms, professional workshops, and demanding hobby users.

PETG from Prof. Lab is known for its stable diameter, reliable spool winding, and consistent quality throughout its length. The grey shade is perfect for technical parts, prototypes, mechanical components, covers, holders, and functional models where a professional, neutral appearance and good readability of details are required.

Main advantages of PETG Prof. Lab Grey 5 kg

• Large 5kg spool – ideal for long-term printing (production, printer farms, large models)
• High toughness and strength – suitable for functional and mechanically stressed parts
• Good thermal resistance – higher temperature stability than PLA
• Low shrinkage and minimal warping – stable dimensions, suitable for precise technical parts
• Excellent interlayer adhesion – strong prints without delamination
• Neutral grey color – professional look, masks small imperfections well
• Quality spool winding – smooth material feeding, without crossing and jams
• Good chemical resistance – suitable for parts exposed to moisture and common chemicals

Recommended use

We especially recommend grey PETG Prof. Lab for:

• Technical and functional parts – holders, grips, covers, brackets, auxiliary tools
• Prototypes and test models – product development, functional verification samples
• Machine parts with higher loads – low-speed gears, stops, stop blocks
• Outdoor and workshop use – elements exposed to moisture and variable temperatures
• Serial production – repeated prints of the same parts, long print series

Printing properties and recommended settings

Parameters are typical for PETG Prof. Lab (specific values may vary slightly depending on the printer and conditions):

• Filament diameter: 1,75 mm (tolerance typically ±0,03 mm)
• Recommended nozzle temperature: approx. 220–245 °C
• Recommended bed temperature: approx. 70–90 °C
• Print speed: usually 40–80 mm/s depending on the model type
• Cooling: rather medium, higher for fine details, moderate for mechanical parts

For the best results we recommend:

• print on a clean and degreased print bed, possibly with an adhesive agent (glue, spray, textured sheet, etc.)
• limit drafts and sudden temperature changes around the printer
• store the filament dry, ideally in a sealable box with silica gel to prevent moisture absorption

Why choose Prof. Lab PETG Grey 5 kg

• Economical packaging – 5 kg on one spool means less packaging waste and less downtime during filament changes.
• Stable quality of the Prof. Lab brand – a proven filament manufacturer used throughout Europe.
• Universal use – suitable for most open FDM/FFF 3D printers on the market.
• Tuned PETG parameters – a combination of strength, durability, and reasonable printability even for advanced hobby users.
