Prototypes and One-Off Parts

Waterjet and laser cutting need no hard tooling, so a single part costs a setup and a cut, not a die. That makes them ideal for prototypes, design changes, and short runs. Send a sketch, a file, or a sample and we will help turn it into a part you can test.

Why cut prototypes by waterjet or laser

  • No dies or tooling, so a design change is a new file, not a new tool
  • The same process scales from one part to a production run
  • Waterjet cuts the real material, including plastic, rubber, and stone, not a stand-in
  • Parts can be bent, welded, drilled, and tapped in the same shop

From idea to part

You don’t need a finished CAD model to start. Many prototypes begin as a sketch with dimensions or an existing part that needs a change. We will ask the questions needed to make it and flag anything that will be expensive or hard to cut.

Then short runs

Once the design is settled, we can cut the next 10 or 100 from the same file. Repeat customers send revisions and reorders the same way.

Common questions

Is there a minimum order?

No. We quote single parts. The setup is spread over fewer pieces, so one-offs cost more per part than a run.

What materials can a prototype be cut from?

Steel, stainless, aluminum, copper, brass, titanium, plastics like HDPE, rubber, foam, stone, tile, and non-tempered glass.

What do I need to send for a quote?

A DXF or DWG file is ideal, but a PDF drawing, a STEP file, a sketch with dimensions, or a photo of the part with a tape measure in the shot is enough to start. Tell us the material, thickness, quantity, and when you need it if you know them. If not, we will ask.
