First Layer PETG in blue is a filament for FDM 3D printing with a round 1.75 mm strand. The spool carries 1 kg of plastic, or 320–330 m, at a density of 1.29–1.4 g/cm³. Coils are laid in rows without crossovers. It is intended for functional parts and decorative pieces.

What you get
- Winding you can rely on — coils sit in rows without crossovers, so the strand is not pinched on the spool.
- 320–330 m on one spool — 1 kg of PETG means fewer pauses for spool changes during a batch.
- Round 1.75 mm strand — the format for FDM extruders built for this diameter.
- Slicer data — a density of 1.29–1.4 g/cm³ for correct part mass estimates.
- One material for two jobs — blue PETG for working parts and for decor.
- Room to mix colors — nine more PETG shades are available in this format.
Who it suits
Makers and owners of FDM printers with an extruder for 1.75 mm filament who print working parts or decorative pieces and want blue PETG on a 1 kg spool.
Who should skip it
Anyone whose printer takes a different filament diameter, owners of resin printers, and buyers who expect a ready temperature profile from the maker, since none is listed.
Use and compatibility
FDM 3D printing of functional parts and decorative pieces. Compatibility with specific printers is not stated; the key points to check are FDM technology and a 1.75 mm strand.

Questions and answers
What filament diameter is this?
1.75 mm with a round cross-section. Before buying, confirm that your printer extruder works with this diameter.
Is one spool enough for a large model?
The spool holds 1 kg of plastic, or 320–330 m of filament. Compare that length with your slicer estimate for the model.
Which print settings are recommended?
The maker does not list nozzle or bed temperatures. Find your settings with a test print such as a temperature tower.
What can I print with this PETG?
Functional parts and decorative pieces that need to be blue.
