Description
Batch-tested blue PETG — a dependable all-rounder. The classic blue gives prototypes and functional parts a clean, professional look, 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
- Classic blue — professional look for prototypes and end-use parts
- High impact resistance and durability
- Weather and UV resistant — suitable for outdoor use
- Minimal warping, no heated chamber required

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: functional prototypes, brackets and mounts, enclosures, machine parts, outdoor equipment.
