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. Orlando teams use our rapid prototyping to test fit, form, and function before committing to production.
Validate Your Design
Upload your CAD file and pick a material. We check your design before cutting.
Test Real Materials
Get a real metal or plastic part. Test strength, weight, and fit on your assembly.
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.

What Engineers Say About
Working With RivCut
Real reviews from real engineers. Every project matters — including yours in Orlando.
We went through two shops before finding RivCut. Night and day difference. Parts come in right. Communication is clear. They held ±0.002" on a titanium bracket that two other shops couldn’t get right.
Aerospace PartsThey caught a tolerance issue in our drawing before production started. That saved us a full revision cycle and three weeks of delays. You don’t find that kind of attention to detail at most shops.
Medical DeviceWe needed fast turnaround on 5-axis parts for a new enclosure. RivCut delivered in 6 days. Quality was excellent. These guys move fast without cutting corners.
