Filament PETG Prof. Lab 1.75mm 1kg Blue High-Strength

The material is characterized by slight elasticity, which translates intoexceptional impact strength and resistance to cracking under the influence of dynamic stress. PETG is naturally 100% insensitive to moisture, water and a wide range of chemicals and acids. Thanks to minimal processing shrinkage, this filament adheres perfectly to the substrate and does not require the use of a closed working chamber. A saturated blue shade with a delicate, glass shine gives the models a professional look. It is an ideal choice for the production of functional parts, moving mechanisms, housings operating in difficult conditions, handles and all outdoor applications. The product works with most open FDM/FFF 3D printers.

Why choose engineering filament Prof. Lab PETG?

• High mechanical and chemical resistance: The copolyester structure provides excellent resistance to impacts, friction and the effects of detergents, oils and atmospheric factors.
• Dimensional stability (Low Warping): Minimal thermal shrinkage allows for trouble-free printing of large engineering details without the risk of corners peeling off the print bed.
• Excellent bonding of layers: High processing temperature guarantees strong inter-layer cohesion in the Z axis, making the finished elements extremely consistent and durable.
• Rigorous precision of diameter: Fixed line size of 1.75 mm with a tolerance of up to ±0.03 mm guarantees fully stable material dosage, preventing blocking of the extruder.

Recommendations and working tips for PETG material:

PETG is a material with very strong adhesion to some surfaces, which requires appropriate preparation of the working platform.

• Table surface protection: Due to the extremely strong adhesion of PETG to clean glass or smooth PEI boards, it is recommended to use separating agents (e.g. PVA glue, dedicated adhesive varnishes). This prevents damage to the table surface when removing the finished model.

• Cooling control: To obtain maximum mechanical strength and cohesion of the layers, it is recommended to limit the cooling airflow (suggested values: 20-50% depending on the geometry). Too intense airflow may weaken polymer bonds.

• Compatibility: Fully compatible with Prusa, Bambu Lab, Creality (Ender), Anycubic devices and other 3D printers supporting nozzle temperatures up to 240°C.

Packaging and storage information:

The filament is wound on a stable, stiff spool in a completely orderly manner, which prevents the line from crossing and tangling during many hours of work sessions. Each spool is factory-packed and hermetically packed in a thick barrier foil in a vacuum cover with an active moisture absorber (silica gel).

Tip: PETG plastics have a natural tendency to absorb moisture from the air superficially (hygroscopicity). After opening the package, it is recommended to store the spool in a dry place, a dedicated dry box container or a tight string bag with an absorbent. If the material becomes damp, it is worth drying it before printing (approx. 60°C for 4-6 hours), which will completely eliminate threading (stringing) and the formation of air bubbles in the structure of the walls.
