Prototyping & Rapid Sampling
Fast, iterative prototyping through our network of fabrication partners in China — from 3D-printed form studies to functional CNC prototypes that look and perform like production units.
Most founders skip prototyping and discover problems after tooling is paid for.
The pressure to move fast leads founders to skip validation. They see prototyping as a delay rather than an investment. But a prototype costs hundreds. A tooling mistake costs tens of thousands.
Without structured testing, issues that could have been caught in days take weeks to fix once tooling is cut. Fit problems, material failures, and tolerance stack-ups all become exponentially more expensive after production starts.
- Rushing to tooling without validating fit, form, or function
- Using the wrong prototype method — a 3D print when you need a CNC functional part
- Skipping documented test criteria and relying on "looks good" approvals
- Losing prototype iteration history, forcing production to start without known risks documented
Prototype Strategy
Determining the right prototyping approach for your stage — form studies for investor pitches, functional prototypes for user testing, or pre-production samples that match final specifications.
Rapid Fabrication
Access to 3D printing (FDM, SLA, SLS), CNC machining, silicone molding, and low-volume production lines — with turnaround times measured in days, not weeks.
Design Validation
Structured testing of prototypes against performance requirements — fit checks, drop tests, material compatibility, and user ergonomics — with documented findings that feed back into the specification.
Production Handoff
A clean transition from validated prototype to production — the final prototype becomes the reference standard against which all production samples and inline inspections are measured.
Strategy & Method Selection
We determine the right prototyping approach for your stage — form studies, functional prototypes, or pre-production samples — with documented test criteria.
Rapid Fabrication & Validation
We coordinate with 3D printing, CNC machining, and low-volume production partners. Each iteration has a hypothesis, a test, and a documented result.
Golden Sample & Handoff
The validated prototype becomes the production reference. We deliver a complete handoff package: CAD, BOM, and quality acceptance criteria.
A prototype costs hundreds. A tooling mistake costs tens of thousands. The math is simple.
Prototyping is the most undervalued phase in product development. Founders rush to production because it feels like progress — but skipping validation creates problems that multiply in cost at every subsequent stage.
We coordinate prototyping through trusted fabrication partners in China, treating each iteration as an engineering discipline, not an art project. Each iteration has a specific hypothesis, a defined test, and a documented result. When the prototype passes, you know your design is ready for production.
What Makes Our Approach Different
- Multiple fabrication methods matched to the right stage — not one-size-fits-all
- Every iteration has a hypothesis, a test, and a documented result
- Clean handoff to production with the prototype as the reference standard
Common Questions
Expedited fabrication takes 24–72 hours for 3D prints and CNC parts. Full prototype-to-production-handoff cycles typically run 2–4 weeks.
Form studies (FDM), visual prototypes (SLA/SLS), functional prototypes (CNC from production materials), and pre-production bridge runs (50–500 units).
Yes. Every iteration has documented test criteria: fit checks, drop tests, material compatibility, and user ergonomics. Results feed back into the specification.
I deliver a complete handoff package: golden sample, prototype history, master reference package, and quality acceptance criteria. Production starts with full context.
