Provide You With Strong NC Machining Resource Support

Iterate part designs quickly and accelerate product development with quick-turn parts. Our automated design analysis will help spot any difficult to machine features before your design is sent to the manufacturing floor and save you from costly reworks further down the product development cycle.

Eliminate downtime spent waiting for parts and safeguard in-house machining with on-demand relief and infinite manufacturing capacity.

We stock more than 30 engineering-grade plastic and metal materials that are suitable for various part applications and industries. Materials range from plastics like ABS, polycarbonate, nylon, and PEEK to aluminum, stainless steel, magnesium, and copper.

Across our six 3D printing technologies, we use a range of commercial-grade thermoset resins, and thermoplastic and metal powders to 3D print parts that are suitable for various part applications and industries. 

If required for your parts, we offer a variety of post-process options such as heat treating, secondary machining, plating, painting, and dyeing to further enhance mechanical properties and cosmetics.

Our industry-leading tolerances and surface finish quality stems from a dedicated process engineering and quality team for each 3D printing technology. We also offer a proprietary material called Microfine™, which can build features as small as 0.0025 in.
