Optimal settings for flawless results with 3DTrcek PETG Refill Filament
PETG is easy to print and does not require an enclosed chamber. It is suitable for most FDM printers and standard nozzles.
These recommended settings serve as a starting point. Although they work for most printers, we recommend fine-tuning for your specific printer setup.
Our materials are tested in our in-house lab to ensure exceptional strength, layer adhesion, and durability. No shortcuts—just reliable, engineering-grade performance.
Tensile and flexural testing validates strength characteristics and ensures reliable mechanical performance.
Thermal analysis ensures consistent melting characteristics and prevents print failures due to temperature variations.
Melt flow index testing ensures predictable extrusion behavior and prevents clogs or under-extrusion issues.
High-precision laser micrometers continuously measure filament diameter to ensure consistent extrusion and layer adhesion.
Cross-sectional analysis ensures perfect roundness for smooth feeding through extruders and consistent print quality.
We inspect every detail on the spool to make sure your prints come out clean, sharp, and perfect.
Everything you need to know about switching to refills
Not at all. Just slide, click, and print. The refill snaps securely into place in under a minute — no tools, no tape, no guesswork. It’s designed to be frustration-proof, even for beginners.
We use industrial-grade machines to wind every spool with exact tension and alignment — no overlaps, no slack. Tangles simply don’t happen.
Absolutely. Our refill coils are designed to fit most standard reusable spools like Bambu Lab right out of the box. For the smoothest experience, we also offer our own reusable spool engineered for perfect compatibility and lightning-fast reloads.
Absolutely! Our spools are specifically designed to work perfectly with Bambu Lab Automatic Material Systems. Thousands of Bambu Lab users have successfully switched to our refills.
Each refill saves approximately 220g of plastic compared to traditional spools. For the average maker printing 10 spools per year, that's 2.2kg of plastic waste prevented annually!
