Rapid Prototyping

A Prototype on Your Desk in 5 Days — Not 5 Weeks.

We've built prototyping into the DNA of our shop since 2009. That means dedicated proto machines, small-batch-friendly pricing, and engineers who understand that a prototype is about learning, not just a part.

  • ▸CNC prototypes: 3–7 days from PO to shipping
  • ▸Vacuum cast prototypes (10–50 pieces): 7–10 days
  • ▸Sheet metal prototypes: 5–7 days
  • ▸Combined assemblies (metal + plastic + finish): 10–14 days

Design guidelines

Follow these rules for optimal cost and lead time. Our engineers flag any DFM issues during quote review.

01
Start With What You Can Test

A prototype that looks perfect but can't validate your assumption is wasted time. Tell us what you want to learn — fit, strength, appearance, assembly — and we'll recommend the right process.

02
Don't Over-Specify Tolerance

Blanket tight tolerances double prototype cost. Call out only the mating features that matter. We'll hold ISO 2768-m everywhere else.

03
Consider Process-Appropriate Material

CNC in production material (aluminum, steel) for mechanical validation. Vacuum cast ABS-like for fit, aesthetics, and marketing samples. SLA for form-study only.

04
Send a Drawing, Even if It's Simple

A quick PDF with critical dimensions, tolerances, and surface finish speeds up quoting by 24 hours. A 3D model alone requires us to guess at intent.

05
Include Assembly Context

If the part mates with an existing component, send that model too. We'll check fits during DFM review instead of discovering issues after machining.

06
Iterate Fast

We quote revisions in 4 hours for returning projects. Most customers iterate 2–3 times before committing to production — that's what prototyping is for.

FAQ

Frequently asked questions

Q01How fast is 'rapid' really?+
For simple CNC prototypes in aluminum or POM, we ship in 3 business days from PO. Complex multi-setup parts or exotic materials take 5–7 days. Assemblies with surface finishing add 2–4 days. These are real numbers from production, not marketing claims.
Q02What's the cheapest way to prototype?+
For appearance-only prototypes, SLA 3D printing. For fit and mechanical testing, CNC in your actual production material. For 10+ parts, vacuum casting beats CNC economics. We'll tell you honestly which is right for your use case.
Q03Can I get a prototype in the final material?+
Almost always. We stock or can quickly source aluminum, steel, stainless, PEEK, Ultem, POM, titanium, brass, copper, and most engineering plastics. For exotic alloys, add 3–5 days for material procurement.
Q04Do you support medical device prototyping?+
Yes — including PEEK, medical stainless (316L), titanium Gr 5, and FDA-safe plastics. We're not ISO 13485 certified, so final production should move to a certified supplier, but for design validation and 510(k) submissions, we deliver consistently.
Q05Can you keep my project confidential?+
We sign NDAs routinely and protect drawing confidentiality per our internal information security policy. Our parent group has served Japanese OEMs for 15+ years where confidentiality is non-negotiable.
