A part breaks that is no longer made or that never had a drawing. The manufacturer no longer exists, no replacement is available, and the machine or equipment is idle. Reverse engineering is for exactly such cases.

Step by step

1. Assessing the part. We look at the part, its size, material and function. We decide whether it can be scanned and which technology to use to make it.

2. Scanning. We scan the part with a 3D scanner. You can bring or send smaller parts, and for larger machines we can scan on site.

3. Creating the model. The scan produces a polygon mesh. From it, we build a model in CAD software. Where the part is damaged or worn, we complete or adjust the shape according to the function of the part.

4. Approval. You can check the model before production.

5. Production. We make the part with the technology that suits its purpose: 3D printing (for example FDM, SLA or SLS) or CNC milling from metal or plastic.

6. Documentation. If needed, we also prepare a drawing so that the part can be ordered again in the future.

When it helps

  • classic cars and older equipment where parts are no longer available,
  • production lines with worn parts and no documentation,
  • modifying an existing part that needs improving,
  • archiving and digitising parts for future production.

What affects the result

  • Condition of the part: damaged areas have to be remodelled.
  • Surface: shiny or transparent surfaces need treatment before scanning.
  • Material and load: this determines whether 3D printing or metal is suitable.
  • Fit requirements: for functional parts, it is worth checking a test piece.

Examples from practice

This is how, for example, a replacement for a seat belt cover for a classic car and an aluminium part without a drawing were made.

Tip: If you have the old part, keep it. Even a damaged piece is a good reference and preserves information that would be lost by guessing.
