What Is Rapid Prototyping?

Rapid prototyping involves specialized manufacturing techniques for making high-quality physical models of a 3D design idea. Prototypes are useful for design improvement, as stepping stones to full production or for engineering testing. They are meant to be quick and economical, without the need for the investment in hard tooling. Many of our clients need to produce a physical part quickly in order to validate a design or to capture a fleeting sales opportunity.

Advantages Of Making A Prototype

How can making a prototype help you and your business? Here are just some of the ways:

  • Show your customers and investors a physical model of your product

  • Demonstrate the appearance, dimensions and features of your product

  • Test the market with your product before production

  • Save time and money by identifying and reducing design flaws

  • Improve and streamline the production process

  • Create multiple versions with different colors, surface textures and finishing processes

CNC Machining

CNC machining is ideal for making high-quality rapid prototypes from plastic or metal without investing in expensive tooling. Your parts will achieve tighter tolerances with better surface finishes than with other prototyping methods. We can also machine all the features needed for a fully functional part, including tapped and threaded holes and precisely flat surfaces.

We have over 30 CNC mills, lathes and EDM machines in-house for all your CNC needs. We also have a multilingual support team to ensure your product development journey is smooth and worry free. Learn more about our CNC machining service.

Metal 3D Printing

Metal 3D printing is ideal for making complex shapes that combine light weight with high strength. You don’t need to invest in hard tooling and parts can be printed in hours rather than days or weeks.

We use a state-of-the-art Renishaw AM250 printer to create fully dense parts for ultimate performance. Just as importantly, we have expert technicians in-house who provide you with an unparalleled degree of engineering expertise to ensure you get the highest quality finished product.

Vacuum Casting

Polyurethane vacuum casting molds create up to 30 high-fidelity copies from your original master pattern. Parts can be molded in a variety of resins, including engineering grade plastics, and even overmolded in multiple materials.

We are experts in making production quality cast copies from master patterns. Not only will you benefit from our exceptional attention to detail, but we also provide a full suite of finishing services to bring your part up to showroom quality. Learn more about what our vacuum casting service can do for you.

SLA/SLS

SLA and SLS are two of the earliest 3D printing or additive manufacturing processes for plastic. Not only are these techniques fast, but they allow you to produce complex internal features impossible to make with traditional manufacturing. We use SLA to make master patterns for vacuum casting molds.

Both are ideal for making small volumes of finished parts or prototypes. If you need larger quantities, try one of our low volume manufacturing services.
