Prototyping Services
Physical prototypes built, tested, and refined until your product performs exactly as intended — using the right method for your design.
Build Your PrototypePrototyping technologies we use
FDM 3D Printing
Fused Deposition Modeling produces affordable, fast concept models and functional prototypes in a wide range of thermoplastics — ideal for early-stage validation and fit/function testing.
SLA 3D Printing
Stereolithography delivers high-resolution, fine-detail parts with smooth surface finish — the go-to method for aesthetic prototypes, presentation models, and parts with tight tolerances.
CNC Machining
Computer-controlled subtractive machining produces precise metal and plastic components with tight tolerances — essential for structural parts, mechanical assemblies, and functional testing under load.
Injection Molding
Low-volume injection molding creates parts in production-representative plastics — critical for validating mold design, gate placement, and material behavior before full tooling investment.
Lost Wax Casting
Investment casting enables complex metal geometries — internal channels, undercuts, and organic shapes — that are difficult or costly to machine. Ideal for jewelry, aerospace, and custom hardware.
Hybrid & Custom
Many products require a combination of methods — machined metal components assembled with 3D-printed housings, for example. We design the prototyping strategy that best fits your product.
Our Prototyping Process
Prototype Strategy
We evaluate your design and goals to determine the right prototyping method, material, and iteration plan. One method doesn't fit all products.
Build
Prototype parts are fabricated — either in-house or through our trusted vendor network — with RMA overseeing quality at every step.
Test & Evaluate
We test against your functional requirements: fit, load-bearing, ergonomics, environmental conditions. Every test result is documented.
Iterate
Based on test findings, we identify what changes are needed, update the CAD, and build the next iteration. Most products need 2–3 rounds.
Validation
The final prototype iteration is signed off against your requirements checklist. This becomes your manufacturing reference.
