Aerospace precision.
Maker-shop soul.

Seattle Prototyping was born in the shadow of the aerospace giants of the Pacific Northwest. Our founders cut their teeth on flight-critical components where tolerances are measured in thousandths and failure is not an option.

That background is in our DNA — but so is the pure joy of making things. We love a good challenge whether it's a flight bracket for a UAV, a custom prop for a film set, or a one-off gadget that just needs to exist in the world.

Engineering-first

We think in tolerances, materials, and load paths — not just aesthetics.

Speed without shortcuts

Fast turnaround is a feature, not an excuse to skip the hard parts.

Creative problem-solving

The best solution isn't always the obvious one. We like to surprise people.

Services

Whether you need one-off prototypes or small production runs, we have the tools and the team.

Rapid Prototyping

Concept to physical prototype in days, not weeks. We work from sketches, CAD files, or napkin drawings — whatever stage you're at, we can take it forward.

  • Concept development
  • Design for manufacturability review
  • Iterative build cycles
  • Functional testing support

Our Process

01

Brief

Tell us what you need — rough idea, detailed spec, or anything in between. We'll ask the right questions.

02

Design Review

We review or create CAD, flag design-for-manufacturing issues, and confirm the scope and timeline.

03

Build

We make it. You'll get progress updates and can check in at our shop in South Seattle whenever you want.

04

Deliver

Inspection, documentation, and delivery. We stand behind our work and support you through integration.

Let's build something.

Whether you have a detailed spec sheet or just a wild idea — we want to hear it. No project is too small, too weird, or too ambitious.

Tell us about your project — what you're building, rough timeline, and any specs you have. We'll get back to you within one business day.
