We help you shape your vision into a clear, manufacturable concept. Our team supports inventors, startups, and engineers with CAD design, product prototyping plans, and design-for-manufacturing (DFM) analysis.

A Prusa MK3S 3D printer with the file sliced on the computer next to it. It is actively 3D printing a prototype for a client. This is a fundamental machine for rapid prototyping and it produces prototypes using a plastic filament. This is known as (FDM)

Rapid Prototyping

Using 3D printing, CNC machining, and metal/plastic fabrication, we deliver functional prototypes in days—not weeks. This stage allows you to test usability, refine features, and make informed decisions before scaling.

Large format resin (SLA) 3D printed part for a large automotive group. This large format print was part of a small batch run of parts for Lomar Machining.

Low-Volume Production

Once your design is proven, we offer small batch manufacturing, short-run production, and custom part machining. This helps you move seamlessly from prototype to market without the overhead of mass production.

Injection molding die plate for Vaucluse Gear. This injection molding die plate was made out of P20 steel, and it was used to produce 20,000 backpack spacer frames, and it was manufactured by our partner, Cove Plastics, in Dayton, TN.

Mass Production

Once your design is proven, we offer small batch manufacturing, short-run production, and custom part machining. This helps you move seamlessly from prototype to market without the overhead of mass production.
