Prof. Lab PETG black 5 kg

Prof. Lab PETG black 5 kg

The large 5kg spool of Prof. Lab PETG filament in an elegant black color is an ideal choice for users who print in higher volumes and want a reliable, strong and dimensionally stable material. PETG is a great compromise between easily printable PLA and durable ABS – it does not break, does not deform as much as ABS and can handle higher loads and temperatures.

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

Main advantages of PETG Prof. Lab

• High mechanical resistance – excellent toughness and impact resistance
• Slight 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 5kg spool – minimum downtime, ideal for farms and serial production

Typical applications

Black PETG Prof. Lab is especially suitable for:

• Functional and technical components – holders, covers, mounts, jigs
• Parts exposed to moisture – components for aquariums, garden, humid environments
• Outdoor use – signs, boxes, covers, mounting elements (handles UV and temperature better than PLA)
• Spare parts and prototypes – mechanically stressed, dimensionally stable parts
• Serial printing – thanks to the 5kg package, ideal for long print series without changing the spool

Recommended print settings

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

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

For the large 5kg spool it is advisable to ensure smooth unwinding (solid holder, possibly bearings) and for longer prints we recommend dry storage of the filament (seal-able boxes, silica gel), because 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 (does not break like PLA)
• Resistance: good against impact, chemicals, UV and moisture
• Suitable for: indoor and outdoor use

Technical specifications

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 a dry place, ideally in a seal-able 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 operators of on-demand 3D printing and print farms
• For advanced hobby users who want a robust, universal material in a large package

PETG black 5 kg Prof. Lab allows you to print in large volumes, without compromising print quality and with minimal downtime for spool changes.

Key features:

• Large 5kg spool of PETG for long print series without frequent filament changes
• Combines the mechanical durability of ABS with printability 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
