3D scanning, reverse engineering and 3D printing create an end-to-end digital process from capture to the finished component.
This allows spare and wear parts to be manufactured faster, more precisely and independently of supply chains.
Practical example: defective timing belt cover was recorded, reconstructed and printed in optimized form in just one working day.
The challenge
In industrial production, a single defective component can bring entire systems to a standstill. But what can you do if original drawings are missing or the manufacturer has long since stopped supplying spare parts?
This is where the combination of 3D scanning, reverse engineering and 3D printing comes in – a digital process that radically simplifies the procurement of spare parts.
The process
Step 1: 3D scan – the digital basis
Before anything can be printed, it must be available digitally.
High-precision 3D scanners are used to capture the existing part – even if it is damaged – to an accuracy of a hundredth of a millimetre. Different methods are used:
Laser scanners, Structured Light scanners or even CT scanners for internal structures.
This creates an exact digital image of the component within a few minutes.
The advantage: Even complex geometries or fine details can be reconstructed – regardless of whether CAD data exists or not.
Step 2: Reverse engineering – from scan to model
Engineers digitally reconstruct the component based on the scan data. Missing geometries are added, weak points are identified and, if necessary, improved.
The result is a 3D model that can be used for design purposes and either corresponds to the original or has been specifically optimized – for example through topology optimizations or adaptations to operating conditions.
This makes reverse engineering the decisive link between reality and digital production.
Step 3: 3D printing – from model to ready-to-use spare part
The physical component is then created from the digital model – layer by layer, precisely and functionally.
The right process is selected depending on the application:
From plastic printing processes such as FDM or SLS to metal-based technologies such as Laser Powder Bed Fusion or Electron Beam Melting.
The result: precisely fitting spare parts in the shortest possible time – without tool costs, without delivery bottlenecks, without downtime.
You want to reproduce your parts individually and quickly. This is possible with our 3D printing services:
The interplay: digital, fast, independent
The true strength lies in the interaction of these technologies.
A defective part is scanned → digitally reconstructed → optimized → and directly reprinted.
This creates a seamless, fully digital process that dissolves traditional supply chain dependencies and drastically reduces downtimes.
Our practical example shows what this looks like in reality:
A defective timing belt cover was replaced within a few hours using 3D scanning, reverse engineering and 3D printing – from capture to installation within one working day.
