Service (04) — Iterate In Days

Rapid Prototyping

Test fit, form and function while the design is still fluid. Our rapid prototyping lane moves your CAD from upload to physical part in as little as 48 hours — with an engineer reviewing every revision.

What It Entails

Speed with engineering judgement

Rapid doesn't mean rushed. Each prototype revision gets a manufacturability review, the right process for what you're testing, and clear feedback on what to change next — so every iteration teaches you something.

  • Looks-like models for stakeholder reviews and user testing.
  • Works-like prototypes for fit checks, tolerance trials and mechanisms.
  • Revision tracking across versions so nothing gets lost between rounds.

Concept validation

Cheap, fast first articles to prove the idea before investing in detail design.

Fit & assembly trials

Print mating parts together and verify tolerances before committing to tooling.

Pre-production pilots

Bridge quantities that look and behave like final parts for field testing.

Capabilities

Pick the lane that fits your deadline

Express 48h

Single-part FDM sprints for urgent design reviews and demos.

Standard 2–4d

The default lane: reviewed, inspected prototypes in days.

Multi-process

FDM bodies with SLA detail parts in one coordinated order.

Iteration packs

Discounted 3-round bundles for teams iterating weekly.

Process

From file to finished part

  1. 01Tell us what you're testing.Looks, fit or function — we match the process and material to the question.
  2. 02Review & print.Same-day file feedback, then priority scheduling on the fastest suitable machine.
  3. 03Learn & iterate.Test, send notes, and we fold improvements into the next revision.

FAQ

Prototyping questions, answered

Files approved before noon can ship within 48 hours for single FDM parts. Multi-part or SLA/SLS prototypes typically take 3–5 days.

Yes — mutual NDAs are standard for prototype work. Your files are never shared, shown or reused, and can be deleted on request after delivery.

Every order includes a free manufacturability review with concrete suggestions — wall thickness, orientation, tolerance relief — before we print.
