Prusament PETG Anthracite Grey 1.75mm 1kg Spool - Precise PETG

In this review of the Prusament PETG Anthracite Grey spool the bottom line is clear: this filament is aimed at makers and professionals who want dependable dimensional accuracy and consistent color for functional prints. The reviewer found the biggest reason to buy is the manufacturer transparency and traceability - every spool can be inspected online - combined with a tighter diameter tolerance that reduces print tuning time. For anyone printing strong, slightly flexible PETG parts where uniform extrusion matters, this PETG delivers consistent, usable results.

Key Features

• In-house manufacturing: Made by Prusa Polymers as part of the same company group, the spool benefits from integrated quality control from formulation to winding.
• Diameter precision: The filament is produced to a tight tolerance of +/- 0.02mm, which helps reduce layer variation and improves first-layer reliability when settings are dialed in.
• Traceable spool data: Each spool includes a QR code so users can inspect measured parameters online and verify color and mechanical consistency before printing.
• Color consistency: Anthracite Grey is monitored for uniform color across the spool to avoid visible shifts in multi-part prints or long runs.
• Thorough testing: The manufacturing process measures string diameter, color, and mechanical properties so most spools arrive ready to print without surprises.

Who It's For

Prusament PETG Anthracite Grey is best for hobbyists, small workshops, and engineers who prioritize repeatable prints and want the ability to check spool metrics before committing to a job. The filament suits functional prototypes, mechanical parts, and aesthetic prints that need a neutral, consistent grey finish.

Those who need specialty PETG blends, flexible TPE materials, or ultra-adhesive beginner-friendly filaments may want to look elsewhere; bed adhesion results reported by customers are mixed, so expect to spend a little time dialing print surfaces and first-layer settings for reliable adhesion.

Pros & Cons

Pros

• High manufacturing precision (+/- 0.02mm) reduces dimensional surprises across prints.
• Full spool traceability via QR code lets users verify measured parameters and color consistency.
• Premium in-house quality control yields strong, functional PETG prints with good color consistency.
• Well suited for parts that require strength with a bit of give.

Cons

• Adhesion performance can vary between printers and beds, so some users report needing extra bed prep.
• Not a specialty filament for extremely flexible or high-temperature engineering applications.

Our Verdict

Prusament PETG Anthracite Grey is a solid choice for users who want a reliably manufactured PETG with verifiable spool data and tighter-than-average diameter control. It represents good value for projects that demand consistent extrusion and color, though you should be prepared to tune bed adhesion for your specific printer and surface.

Frequently Asked Questions

Can I check the spool data before printing?
Yes, each spool includes a QR code linking to measured parameters and quality data for that specific spool.

What diameter is the filament?
The filament is 1.75mm with a manufacturing tolerance of +/- 0.02mm.

Is this PETG easy to get to stick to the bed?
Adhesion results vary by printer and surface; many users get reliable adhesion with proper bed prep but some report needing additional measures like glue stick or textured sheets.
