Our Capabilities –

Prototyping Methodology

We’re an internationally approved supplier with in-house capabilities to create impactful designs on a limited budget. Together, we can execute your concept through world-class machinery, printing resources, and proprietary processes.


This printer is known as an FDM (Fused Deposition Modeling) printer. This is good for rough concept prototypes and form study models.


Ideal for high-resolution finishes on medium to large projects, SLA is a cost-effective way to get a durable, aesthetically pleasing prototype on a tight deadline. Outsourced SLA prints allow for more fine detail and a larger material selection.


This powder-based additive is great for detailed projects that involve a high level of complexity, organic geometries, and parts that need to be durable.


MJF is quickly becoming the go-to choice for prototypes and production parts—enclosures, electronic housings, ducts, lattice structures, and parts that require great detail and durability.


This process uses a vacuum to fill a mold, giving the designer an air-free solution for details, undercuts, and wire/fiber reinforcement. Vacuum casting is the closest prototyping solution to a final injection molded production part, with the most accurate materials possible.


To round out your prototype or production material, we can achieve high-quality finishes through painting, electrochemical processes, protective coatings, and more.

Program & Skills

No tool or machine is as important as the mind behind it. As a product design firm, we rely heavily on rapid prototyping for development. We’re experts in 3D printing and consistently are at the cutting edge of its burgeoning technology. We’re highly trained in CAD software and a variety of 3D printing slicing software to achieve a high level of detail and precision for your project.


We can help you hone your idea with the process in mind, giving input on the CAD model, printer, and materials based on your budget and goals.


Through our experience in product design, we can help you make your print by strategizing the project based on your goals— prototyping, sizing, color, durability, etc.


Once the idea and printing strategy is set, we can use our 50+ years of combined experience to refine CAD models for optimal printing and execute detailed perfection.
