Proto Labs, an internet CNC machine shop, uses subtractive machining combined with proprietary automation software to deliver real parts, really fast.
We employ both milling and turning:
3-axis milling and 5-axis indexed milling to produce complex geometries.
Our turning process includes live tooling to create off-axis holes, flats, slots, and grooves.
More than 30 engineering-grade plastics and metals available, including: PVC, aluminum, brass, stainless steel, titanium, polycarbonate, and more.
