What We Do

Our Rapid Prototyping Services: From File to Physical in Days.

Rapid prototyping bridges the gap between digital design and physical reality. We transform your CAD files into functional prototypes that you can hold, test, and refine — before committing to expensive production tooling.

Our capabilities span multiple technologies, allowing us to match the right process to your material, surface finish, tolerance, and timeline requirements.

FDM 3D Printing

Fast, cost-effective plastic prototypes for concept validation. Best for early-stage design reviews.

SLA / SLS Printing

SLA provides high-resolution, smooth appearance prototypes, while SLS produces durable nylon parts for functional testing and complex geometries.

CNC Machining

Metal and plastic prototypes with production-grade accuracy. Best for stress testing and functional validation.

Urethane Casting

Small batches of production-like plastic parts from silicone molds. Perfect for pilot runs of 10–100 pieces.

Prototype Injection Molding

Fast aluminum or simplified tooling for injection-molded parts in production materials. Ideal for validating fit, function, assembly, surface quality, and molding performance before committing to production tooling.

Our Process

Rapid Prototyping Process: File to Prototype in 5 Steps

A streamlined process built for speed without sacrificing accuracy or quality.

01

File Review & DFM Check

We review your CAD files for manufacturability, dimensional risks, material requirements, and process-specific constraints before prototype production begins.
02

Process & Material Selection

We recommend the optimal prototyping method and material based on your functional and aesthetic requirements.
03

Prototype Production

Parts are produced using the selected technology — 3D printing, CNC machining, urethane casting, or prototype injection molding — based on the required material, quantity, and validation goals.
04

Post-Processing & Finishing

Sanding, painting, plating, or coating applied as needed to achieve the desired surface finish and appearance.
05

Quality Inspection & Delivery

Each prototype is measured against your drawing tolerances before being securely packaged and shipped.

Use Cases

When to Use Rapid
Prototyping

Concept Validation

Test your design concept early — before spending money on tooling. Identify and fix flaws when changes are still cheap and fast.

Functional Testing

Validate fit, form, and function with parts that behave like production components — test mechanisms, stress, and assembly.

Investor & Sales Samples

High-quality appearance models to present to investors, trade shows, or early customers before production begins.

Tooling Verification

Validate critical geometry, assembly interfaces, draft-sensitive features, and parting-line concepts before committing to production tooling.

Market Testing

Produce small batches using urethane casting or prototype injection molding for pilot builds, market testing, and customer evaluation before full production tooling.

Regulatory Approval

We can produce evaluation samples and supporting inspection documentation based on project requirements. Suitability for formal certification testing depends on the specified material, manufacturing process, and applicable standard.

Benefits

Benefits of Rapid Prototyping

Rapid prototyping enables manufacturers, engineers, and product designers to evaluate concepts before investing in expensive tooling and production equipment. By creating physical models early in the development cycle, companies can identify design flaws, verify functionality, and improve product performance.

Our rapid prototyping services support a wide range of industries including consumer electronics, automotive components, medical devices, industrial equipment, and household products. Whether you require a simple concept model or a fully functional engineering prototype, we can recommend the most suitable manufacturing process.

Combining 3D printing, CNC machining, urethane casting, and prototype injection molding allows us to balance speed, cost, accuracy, material performance, and production relevance throughout product development.

FAQ

Rapid Prototyping FAQ

Everything you need to know before ordering your first prototype.

What file formats do you accept?

We accept STEP, IGES, STL, OBJ, and most major CAD formats including SolidWorks, Fusion 360, and Rhino files. If you only have 2D drawings or sketches, our team can help create the 3D model.

FDM prototypes can be ready in 1–3 days. SLA/SLS typically takes 2–5 days. CNC machined parts take 5–10 days depending on complexity. Rush orders can often be accommodated — contact us for availability.

Yes. Our CNC machining capability covers aluminum, stainless steel, titanium, brass, and various engineering plastics. Metal prototypes are ideal for structural and functional testing where plastic substitutes won’t suffice.

Absolutely. We offer full end-to-end product development — from rapid prototyping through mold design, mold manufacturing, and injection molding production. No vendor handoffs required.

Yes. We can sign an NDA before confidential project files are shared. CAD data, drawings, and project information are handled under controlled access throughout development.
