Product description

Prof. Lab PETG Black 5 kg

The large 5 kg spool of PETG filament Prof. Lab in an elegant Black color is an ideal choice for users who print in larger volumes and want a reliable, strong, and dimensionally stable material. PETG is a great compromise between easy-to-print PLA and durable ABS – it doesn't break, doesn't deform as much as ABS, and can handle higher loads and temperatures.

This description is based on verified parameters and typical properties of PETG Prof. Lab (1 kg variants), adapted for the large 5 kg spool of the same material.


Main advantages of PETG Prof. Lab

  • High mechanical resistance – excellent toughness and impact resistance
  • Moderate flexibility – less brittle than PLA, suitable for functional parts
  • Good chemical resistance – resists common chemicals, oils, and moisture
  • Higher temperature resistance than PLA – more suitable for warmer environments
  • Low shrinkage and warping – stable dimensions, fewer deformations during printing
  • Matte black surface – representative appearance of technical and design parts
  • Large 5 kg spool – minimum downtime, ideal for farms and serial production

Typical use

Black PETG Prof. Lab is particularly suitable for:

  • Functional and technical components – brackets, covers, grips, fixtures
  • Parts exposed to moisture – components for aquariums, gardens, humid environments
  • Outdoor use – signs, boxes, covers, mounting elements (tolerates UV and temperature better than PLA)
  • Spare parts and prototypes – mechanically stressed, shape-stable parts
  • Serial printing – thanks to the 5 kg package, ideal for long print series without spool changes

Recommended printing parameters

Parameters are based on verified data for PETG Prof. Lab (1 kg spools of the same material and manufacturer):

  • Nozzle temperature: 230–250 °C
  • Bed temperature: 80–90 °C
  • Printing speed: 30–70 mm/s (recommended 40–60 mm/s)
  • Cooling: approx. 50–70 % (turn on after the first 2–3 layers)

For a large 5 kg spool, it is advisable to ensure smooth unwinding (sturdy holder, possibly bearings), and for longer prints, we recommend dry storage of the filament (sealable boxes, silica gel), as PETG is moderately hygroscopic.


Properties and material

  • Material: PETG (polyethylene terephthalate glycol)
  • Type: filament for FDM/FFF 3D printing
  • Surface: rather semi-matte to matte in black color
  • Stiffness: high, with some flexibility (doesn't break like PLA)
  • Resistance: good against impact, chemicals, UV, and moisture
  • Suitable for: interior and exterior use

Note: Specific settings may vary depending on the printer, hotend, bed, and airflow. We recommend performing a short test print and fine-tuning the parameters.


Storage and handling

  • Store in dry conditions, ideally in a sealable box with desiccant
  • Protect from direct sunlight and high temperatures
  • For large spools, ensure stable mounting and smooth unwinding to prevent skipping or uneven filament tension

Who is PETG Prof. Lab 5 kg ideal for?

  • For companies and workshops with regular production of functional parts
  • For custom 3D printing operators and print farms
  • For advanced hobby users who want a robust, versatile material in a large package

PETG Black 5 kg Prof. Lab allows you to print at scale, without compromising print quality and with minimum downtime for spool changes.

Key features:

  • Large 5 kg PETG spool for long print series without frequent filament changes
  • Combines mechanical resistance of ABS with easy printing similar to PLA
  • Black color with a technical look suitable for functional and design parts
  • High resistance to moisture, chemicals, and weathering
  • Low shrinkage and good dimensional stability – lower risk of warping
  • Suitable for serial and professional printing in 3D printer farms
