Yellow Square blue PETG is a filament for FDM 3D printing: a round 1.75 mm strand with 1 kg of material on the spool, or 320–330 m. Density is 1.29–1.4 g/cm³, and the spool is row-wound without crossovers. It is meant for functional parts and decorative pieces.

What you get
- Stock for a batch of parts — 1 kg of PETG on one spool, or 320–330 m of strand.
- Even feeding — row winding without crossovers keeps a loop from pinching the strand mid-print.
- A clear filament format — 1.75 mm diameter with a round cross-section.
- More accurate weight estimates — enter the 1.29–1.4 g/cm³ density in your slicer material profile.
- Blue color — for parts you want to stand out in an assembly or on a shelf.
- Nine more colors in the same format — from black to white, so multi-color builds stay in one material.
Who it suits
Anyone printing on FDM equipment with 1.75 mm filament: makers, modelers and engineers producing working parts, plus hobbyists printing decor who want 320–330 m on a single spool.
Who should skip it
Owners of printers built for a different filament diameter or of resin printers. It also will not suit anyone expecting ready-made temperature settings from the maker: none are listed, so you will need to tune them yourself.
Use and compatibility
Use: FDM 3D printing of functional parts and decorative pieces. No list of compatible printer models is provided; check that your extruder takes 1.75 mm filament.
What is in the box
A spool of blue PETG filament, 1.75 mm, 1 kg.
Questions and answers
How many meters of filament are on the spool?
320–330 m, with a filament weight of 1 kg.
What temperature should I print at?
Print temperatures are not specified. Find them with a test model, changing the nozzle temperature in small steps.
Will the filament tangle on the spool?
The winding is neat, in rows and without crossovers, so coils do not lie across each other and the strand pays out evenly.
Which other colors come in this format?
Black, red, purple, gray, blue, pink, orange, green, yellow and white.
