Prototype Machining

First articles and functional prototypes in days, not weeks. Iterate fast with a shop that gives you DFM feedback before you commit.

Small-Batch Production

Repeatable quality from 1 to 1000 pieces. Documented processes, inspection data, and consistent parts — every run.

DFM & Design Support

We review your CAD before quoting and flag manufacturability issues upfront. DFM advice always included.

Finishing & Assembly

Anodizing, tumbling, and anything else — managed in house or through our network of vetted finishing vendors so you get complete products, not just machined parts.

Problem vs Solution

Not Your Typical Machine Shop Experience

The Typical Experience

Small orders get deprioritized — or quietly turned away.

Quotes take a week. Follow-ups take longer.

You get a price, but no insight into what's driving it up.

Once the PO is signed, you hear nothing until it ships.

You're a line item in their system. They don't know your product.

Working With Bivy Works

No job is too small. 1 piece or 1000 — same attention, same priority.

We'll get on a call within 24 hours to discuss your project. Guaranteed.

DFM review included with every quote. We flag cost savings before you commit.

Track your job's progress anytime through our customer portal.

We learn your product and your goals. The more we work together, the better your parts get.

Common questions

Frequently Asked Questions

Do you have a minimum order quantity?

No! We take on single prototypes through 1000 piece production runs. No job is too small.

What files do you accept?

STP, STEP, IGES, Fusion 360, SolidWorks, and most native CAD formats. Don't have a CAD file yet? A sketch or concept works too — we'll help you figure out the rest.

How fast can I get parts?

It depends on complexity and quantity, but most prototype jobs ship within 1–2 weeks. We'll give you a clear timeline before you commit.

What materials do you work with?

Aluminum alloys (6061, 7075), stainless steels, carbon and alloy steels, titanium, nickel-based superalloys, brass, copper, engineering plastics and more! If you're unsure what material is right for your application, we can help you decide.

What if I only have a rough idea, not a finished design?

That's fine. We work with teams at every stage — from napkin sketch to production-ready CAD. Book a call and we'll figure out the best path forward together.
