What we do.
FDM contract manufacturing across prototyping, tooling, replacement parts, and short-run production, with in-house 3D scanning for reverse engineering.
FDM / Additive Manufacturing
Production-grade fused-deposition printing for functional end-use parts and assemblies.
Rapid Prototyping
Fast iteration on form, fit, and function: concept to physical part in days, not weeks.
Jigs & Fixtures
Custom tooling, alignment fixtures, and assembly aids tailored to your process.
Replacement Parts
Obsolete, hard-to-source, or discontinued components reproduced from drawings or samples.
Low-Volume Production Runs
Repeatable short-run manufacturing with consistent dimensional output unit to unit.
3D Scanning & Reverse Engineering
Digitize an existing part into a working model when there are no drawings. Legacy hardware, worn components, and one-off samples.
In-House Design Support
Design-for-additive guidance and modeling to turn requirements into printable parts.
The full process portfolio. Nothing is listed as live until it is running in the shop.
Design / CAD
In-houseLIVEEvery product starts as an in-house model. Design-for-additive guidance and drawing support included.
FDM Additive Manufacturing
In-houseLIVEProduction-grade FDM in PETG, PCTG, ABS, and ASA. Prototypes through low-volume production.
3D Scanning
In-houseLIVERevopoint POP 4 handheld scanner, in-house. Rated 0.03 mm single-frame in laser mode and 0.03 mm + 0.05 mm/m volumetric, on parts up to 2 m. Delivered tolerance depends on part geometry, surface, and finish. Ask and we will tell you what is realistic for yours.
