What Is Rapid Prototyping?

CNC prototyping makes real parts from real materials — fast. Unlike 3D printing, your prototype is made the same way as your production part. This means you can test fit, function, and strength before committing to a full run. El Segundo teams use our rapid prototyping to test fit, form, and function before committing to production.

1

Validate Your Design

Upload your CAD file and pick a material. We check your design before cutting.

2

Test Real Materials

Get a real metal or plastic part. Test strength, weight, and fit on your assembly.

3

Iterate Fast

Make changes and get the next version in days. Lock in your design before production.

Built for Speed & Iteration

Your prototype deserves a machining partner who moves as fast as your team — without cutting corners on quality.

Speed — 3-Day Rush

Prototypes ship in as few as 3 business days. Same-day quotes keep your project on track. No waiting weeks for simple parts.

CMM Inspection

Every prototype is CMM inspected before shipping. You get a documented inspection report — not a guess. Know your part is right before you test it.

Design Iteration Support

Update your file and get a new part fast. We store every version so you can compare revisions. Most teams go through 3 to 5 rounds before locking in.

Low-Volume Friendly

Order one part or fifty. No minimum quantity and no setup fees on most orders. Perfect for testing multiple versions or investor demos.

Prototype Part Types

From functional test parts to investor demos — precision machined and ready to test.

In El Segundo, aerospace companies drive demand for rapid prototyping. Local teams working with Boeing Satellite Systems and Northrop Grumman Space Park rely on fast-turn CNC prototypes to test fit, form, and function before production.

El Segundo also has a strong defense presence that drives demand for fast-turn CNC prototypes to test fit, form, and function before production. Teams at Los Angeles Air Force Base and Raytheon Space & Airborne Systems use our services for critical components. El Segundo is a critical command center for national defense, home to the Los Angeles Air Force Base and RTX (Raytheon) Space and Airborne Systems.

Enclosures & Housings

Prototype electronics enclosures, sensor housings, and device shells in aluminum or stainless. Test fit, thermal performance, and assembly before committing.

Al 6061 & 7075

Structural Brackets

Load-bearing brackets, motor mounts, and structural interfaces. Test strength and stiffness on real materials before finalizing your design.

From CAD File to Prototype in Days

Three steps. No runaround. Built for teams that move fast.

Step 1

Upload Your CAD File

Send your STEP or IGES file. Select material, quantity, and finish. We review for manufacturability and respond fast.

Step 2

We Machine & Inspect

Your prototype runs on our CNC mills and lathes. Every order gets CMM inspection. We verify every critical dimension before anything ships.

Step 3

Test, Iterate, Scale

Test your prototype for fit and function. Need changes? Send a new file and we turn it around fast. Ready for production? We scale up with the same tooling.

Common Questions About CNC Prototyping

Most prototypes ship in 5 to 7 business days. Rush orders go out in as few as 3 days. Simple aluminum parts are the fastest. Complex multi-setup parts take a bit longer.
A single aluminum prototype starts around $75 to $200. Steel and titanium cost more. Price depends on size, features, and finish. Upload your file for an exact quote the same day.
Yes. We have no minimum. Order a single part to check fit, or order 10 to test different versions. Many teams order 1-piece first, then 5-10 after design changes.
Verify ITAR registration and secure file transfer protocols before sharing satellite or radar model files in El Segundo. RivCut provides full material traceability, CMM inspection on every part, and first-article inspection reports on request.
El Segundo is a premier global aerospace hub, home to the Los Angeles Air Force Base, Aerospace Corporation, Boeing Satellite Systems, and Northrop Grumman Space Park. This creates strong local demand for Rapid Prototyping services with fast turnaround and rigorous quality standards.
Yes. Beyond aerospace, we also serve El Segundo's defense sector with the same precision and documentation rigor. Teams supporting Los Angeles Air Force Base and other local defense firms use our services.
Yes. We sign NDAs before we see your files. Your early-stage designs stay private. Startup founders and defense teams trust us with pre-launch prototypes.
We take STEP, IGES, DXF, PDF, SolidWorks (.sldprt), and STL files. STEP is best for prototyping because it keeps full geometry and tolerances.
Yes. That is the biggest win of CNC prototyping. Your prototype uses the same process as production. When you are ready for volume, we already have your toolpaths and material specs locked in.
