Our CNC Prototyping Service

  • Speed

    CNC prototyping delivers fast turnaround times, allowing you to quickly iterate through multiple design versions. The automated machining process enables building parts in hours/days rather than weeks.

  • Accuracy

    Precision CNC machines provide tight tolerances down to ±0.005 inches or less. Parts match the 3D CAD model dimensions and operate as designed for concept validation.

  • Flexibility

    CNC can handle plastics, metals, foam, wood, and more. It supports complex geometries and can make small batches with different materials. The process is easily adjustable for design changes.

Cases of CNC Prototyping Service

Medical Device
Medical Device

A medical startup needed to test prototypes of a new laparoscopic surgery device for ergonomics and functionality. They partnered with a CNC prototyping shop to produce multiple design iterations out of plastic resin, enabling surgeons to trial the grip, weight, and usability of the device before finalizing the design. Rapid CNC machining provided cost-effective prototypes in 1-2 days, allowing quick design modifications throughout the development process. This accelerated the path to regulatory approval and product launch.


An engineering team was building a robot arm for warehouse order fulfillment but needed prototyping services to test their aluminum alloy design. The CNC shop quickly machined the complex robotic arm components to fine tolerances for assembly. The fully functioning prototype allowed the engineers to evaluate strength, range of motion, and precision for the robot's picking and placing capabilities. Multiple versions were iterated via CNC until the perfect design was achieved.

Consumer Product
Consumer Product

When launching a new electric toothbrush, the consumer goods company used CNC prototyping to test and modify injection molds, production line jigs and fixtures. This process refinement saved significant time and money during full-scale manufacturing. The CNC shop quickly machined mold and tooling prototypes from aircraft-grade aluminum, enabling the company to fine-tune the production system prior to high volume output.

  • Q

    What is an advantage of CNC Prototyping?


    CNC prototyping enables fast fabrication of highly accurate parts, allowing for rapid design validation and testing before committing to full production.

  • Q

    What is the difference between lost-wax casting and CNC Prototyping?


    Lost-wax casting involves sculpting a wax model, molding and casting it, then melting the wax out. CNC prototyping uses automated machining to precisely cut parts from raw material like metal or plastic.
