Product and Machine Design in Chattanooga, TN

ProtoProof provides product and machine design in Chattanooga, TN, for startups and engineers across the Southeast, turning raw ideas into manufacturable 3D CAD designs engineered for safety, performance and scalability from the start.

Product and Machine Design With CAD and DFM

We guide startups and engineers through CAD modeling and rigorous design-for-manufacturing (DFM) analysis. We simulate part interfaces early to save both time and capital on redundant prototypes.

How a Design Project Runs

[01]

Needs Discovery

We identify critical constraints like operating temperatures, tolerances, and biocompatibility.

[02]

CAD Modeling

We create or refine detailed 3D files in Fusion 360, Solidworks, and Rhino.

[03]

DFM Analysis

We evaluate geometry and thermal expansion to ensure scalable manufacturability.

[04]

Prototyping Plans

We outline the most cost-effective path forward for your specific material needs.

[05]

Material Selection

We consult on polymers ranging from carbon-fiber nylon to silicone-like materials.

[06]

Custom Fabrication Planning

We design sacrificial molds and custom weld joints for oversized components.

Questions About Machine Concept & Design

[01]

What CAD Software Do You Use?

Fusion 360, Solidworks, Rhino and CREO.

[02]

What Is DFM Analysis?

Design for manufacturing (DFM) analysis checks your part's geometry, thermal expansion and material shrinkage, so the design can be produced at scale without costly redesigns.

[03]

Is My Design Kept Confidential?

Yes. We review your files under a mutual NDA.

Let's build it better.
