Our parts are draft-fit prototypes printed in PLA Tough+ (Gray) only.
Intended for fit, clearance, and general prototyping — not cosmetic finish or production strength.
Not for life-safety, medical, food contact, vehicles/aviation, or mains-powered electrical use.
PLA softens around ~60 °C; not suitable for hot cars, outdoor/UV exposure, or solvents.
Typical tolerances: ±0.3 mm (XY), ±0.4–0.6 mm (Z). Visible layer lines and light support marks are expected.
Thin features (<1.0 mm walls/pins) are “best-effort” only.
Max single-part size: ~180 × 180 × 180 mm (~7.1″ cube).
Material: Bambu PLA Tough+ (Gray) only (no sanding/painting by default).
Prints are not certified (no UL/CE/flammability ratings).
For bench prototyping only; keep away from mains voltages and heat sources.
We don’t print weapons or weapon parts (including receivers, frames, suppressors, conversion devices), illegal items, or designs that infringe IP or law.
We may refuse or cancel a job at our discretion.
We email a written quote with scope, price, and ETA. Printing starts only after your email approval.
If files or settings change after approval, we’ll requote.
If we make a mistake, we reprint at no charge. Otherwise, changes or new scope are quoted.
