Description
Batch-tested black PETG — the workhorse color for functional and mechanical parts. The deep, uniform black hides layer lines for a professional-looking finish, while the filament resists impact, moisture, and UV far better than PLA. Every spool passes diameter and printability checks before packing, so extrusion stays steady from the first meter to the last.
Why choose this filament
- Deep uniform black — hides layer lines for a professional finish
- High impact resistance and durability
- Weather and UV resistant — suitable for outdoor use
- Chemical resistance for workshop and industrial use

Printing Tips for PETG
PETG bridges the gap between easy-to-print PLA and tough engineering plastics. Run the nozzle at 230–245 °C and the bed at 70–80 °C, and slow the first layer to about 20 mm/s so the part locks down without a brim. Keep part cooling low — around 30–50% — which is enough to sharpen detail without weakening the layer bond that gives PETG its impact resistance.
- Leave a little extra nozzle clearance: PETG is tacky and over-extrusion builds up on the hotend
- A PEI sheet, or glass with a light glue stick, releases PETG cleanly without tearing the surface
- Hold flow rates around 40–60 mm/s for strong, glassy layers
Storage and Batch Quality
PETG absorbs moisture faster than PLA, and wet PETG shows it immediately as popping, stringing and cloudy layers. Keep sealed spools with the desiccant pack, and dry an opened spool at 65 °C for 3–4 hours before a long or load-bearing print. Every batch is measured across the full spool at ±0.02 mm and vacuum-sealed the day it is extruded, so performance stays consistent from your first order to your fiftieth.
Applications: machine parts, brackets and mounts, enclosures, jigs and fixtures, everyday functional prints.
