CAD design services typically cost anywhere from a few hundred dollars for a single simple part to five figures for a complete multi-part product engineered for production. Hourly rates for professional mechanical CAD work in the US market generally run from roughly $50 to $200 per hour depending on seniority and firm type, with freelancers at the lower end and established engineering firms at the higher end. The wide range is honest: "CAD design" covers everything from tracing a sketch into a printable model to engineering an injection-molded assembly with tolerance stacks and full production drawings. This guide breaks down what drives the price and what you should receive for your money.

What Drives CAD Design Pricing

  • Complexity and part count: a one-piece bracket is hours of work; a snap-together enclosure with buttons, seals, and internal bosses is days to weeks.
  • Purpose of the model: a concept model for visualization is far cheaper than a production model with draft, tolerances, and material callouts ready for design for manufacturing.
  • Surfacing: organic, sculpted consumer-product surfaces (the domain of industrial design) take specialized skill and more time than prismatic mechanical shapes.
  • Analysis: if the part must survive loads, heat, or drops, expect engineering calculations or simulation on top of modeling.
  • Iterations: revisions after prototype testing are normal — clarify whether they are included or billed hourly.

Typical Price Ranges

  • Simple single part (bracket, adapter, knob): low hundreds of dollars.
  • Moderate part or small assembly (enclosure with lid, mount with hardware): high hundreds to a few thousand dollars.
  • Full consumer product (multi-part housing, mechanisms, production intent): several thousand to tens of thousands of dollars, usually delivered inside a broader mechanical engineering effort.
  • Reverse engineering an existing physical part: hundreds to thousands, depending on scan complexity and required accuracy.

Treat suspiciously cheap quotes for production-intent work with caution. A model that ignores draft angles, wall thickness, and tolerances will be redone — by someone — before a factory can use it.

Deliverables You Should Insist On

The files you receive matter as much as the design itself. A professional package includes:

  • Native CAD files (SolidWorks, Fusion, Onshape, etc.) — not just exports — so future engineers can edit the design. You paid for it; own it.
  • Neutral formats (STEP for manufacturing, STL/3MF for printing) for quoting and prototyping.
  • 2D drawings with critical dimensions and tolerances for any part a factory will make.
  • A bill of materials for assemblies, including off-the-shelf hardware.
  • Renderings if you need marketing or crowdfunding visuals.

Freelancer, Firm, or In-House?

Freelancers are cost-effective for well-defined single parts. Engineering firms cost more per hour but bring multidisciplinary review — a mechanical designer who talks daily to electronics and manufacturing engineers catches problems a solo modeler cannot. Our guide to product development services explains how CAD fits into full-service development, and if you are comparing partners, see how to choose a product design firm.

How to Brief a CAD Designer and Keep Costs Down

  • Bring sketches, reference products, and dimensions — even rough phone photos with a ruler in frame cut hours of guesswork.
  • State the end goal: 3D print, CNC, or injection molding. The target process shapes the model from the first feature; our overview of prototype development shows why.
  • Fix the requirements before modeling starts; changing them mid-project is the most common source of budget overruns.
  • Ask for a fixed quote with a defined revision count for well-scoped work, hourly only for exploratory work.

From CAD Model to Physical Part

A good CAD package flows straight into prototyping — 3D printing for fast iterations, then production processes when the design stabilizes. If your designer cannot tell you how the part will be made, they are drawing pictures, not engineering parts.

Projects House provides production-grade CAD design as part of complete product engineering: models built for real manufacturing processes, with drawings and files you fully own. Describe your part or product in our contact form and we will give you a clear, fixed-scope quote.
