Prototype Development Services

A prototype answers the questions a screen cannot. Does it fit? Does it clear the bracket next to it? Is it comfortable to hold, easy to install, strong enough where it matters?

DCD builds prototypes from Martinsville, Indiana for customers across Indianapolis and Central Indiana, usually as a step between CAD design and production.

Why prototype first

Finding a problem in a prototype costs a few days. Finding the same problem after a production run costs the run.

Prototypes catch the mistakes that are almost invisible in CAD: a fastener that cannot be reached with a real wrench, a cable that has nowhere to route, an assembly order that only works if you have three hands, a part that is technically within tolerance but feels wrong. These are the details that separate a design that works on paper from one that works in the field.

Different prototypes for different questions

Not every prototype needs to be a finished part. A quick 3D print is often enough to check fit and clearance — cheap, fast, and entirely adequate when the question is geometric.

When the question is about strength, wear, heat, or how the part behaves under real load, the prototype needs to be made closer to the real thing, in the real material, by the real process. That costs more and takes longer, so it is worth being clear up front about what you are trying to learn.

I will recommend the cheapest prototype that actually answers your question, not the most impressive one.

Iteration is the point

The first prototype is rarely the last. Because designs are modeled parametrically, revisions are usually quick — change the dimension, update the drawing, print the next version.

Most projects go through two or three rounds before the design settles. That is a normal, healthy process, not a sign something went wrong.

From prototype to production

Once a prototype proves out, the same CAD carries into production: drawings, cut files, and manufacturing data all come from the model you already validated. Parts are produced hands-on where capability allows, or through a trusted manufacturing network when that is the right route.

That continuity is the advantage of having design and production planning handled by the same person — nothing gets lost in a handoff.

Getting started

Bring a design, a sketch, or a problem. If CAD already exists, prototyping can start immediately. If not, the design work comes first, and the prototype follows from it.
