Easy PETG Refill Graphite 850g Fiberlogy
REFILL – environmentally friendly and economical solution
REFILL is a spool-less filament that easily mounts onto the Fiberlogy reel. This solution helps to reduce waste, optimise transport costs and support the zero waste concept. REFILL retains all the properties of standard filaments.
Installation is extremely easy: open the spool, insert the REFILL, close it and cut the fixing strips. Your reel is ready for printing.

Product Description
- High quality PET-G filament combining easy printing, excellent appearance and high mechanical strength
- Provides a balance between strength and printability comparable to EASY PLA
- Resistant to mechanical stresses, chemicals and external conditions thanks to the glycol content
- Allows the creation of transparent details with excellent adhesion between layers
- Minimizes typical PET-G problems – stringing, bubbling and burnout
- Easy to print – achieves aesthetic and robust models even with standard 3D printers
- Suitable for both hobby users and professional applications
- Available in 1.75 mm diameter, in transparent and opaque versions
- Available in a wide range of rich colours with a modern and attractive look
- Ideal for decorative items, electronics boxes, containers and functional parts
Recommendations and settings
