About Project

Replacement parts can be expensive, especially when they’ve been discontinued by the manufacturer. FacFox can quickly reverse engineer replacement parts to lower your maintenance costs or create custom parts to better suit your needs.

One of our clients bought his BMW 7 several years ago. Recently a gear inside the doorstop just broke and the suppliers did not offer the spare parts anymore. He came up with the idea of using 3D printing to make a new one.


  • Step 1: Images of the part are submitted via email and evaluated. A preliminary price is quoted to the customer based on the images provided. The client then sends the physical part. If it differs from the original photo, the price may be adjusted.
  • Step 2: The part is measured with precision tools to accurately capture its shape and size. This information is used to create a 3D model of the part using SolidWorks.
  • Step 3: The completed 3D CAD file is then used by FacFox to manufacture with FDM 3D printing technology. We recommend using ASA as it’s a strong, UV resistant FDM material available in 10 colors for rapid prototyping and production parts.
