The job of a maintenance technician requires diagnosing and repairing equipment quickly. 3D technology makes it possible to create digital twins of machinery, making it easier to locate faults without disassembling parts. For example, a 3D scanner can capture a broken part and print a temporary replacement in hours, avoiding long downtimes. Programs like Fusion 360 or Blender model the parts, while Cura or PrusaSlicer prepare the files for printing.
Scanning and modeling for precise diagnostics 🛠️
The workflow begins by scanning the damaged component with a device like the Einscan SE. The capture software generates a point cloud that is converted into a mesh in MeshMixer. Then, in Fusion 360, the model is refined by adding fit tolerances. Finally, it is exported to STL and processed in Cura for the 3D printer. This method reduces the waiting time for original spare parts and allows adapting parts to old equipment without documentation. A technician with these tools can solve breakdowns in one shift.
When the spare part arrives on the printer, not on the truck 🚛
Of course, there will always be the boss who says: And what if the printed part breaks in three days? Well, print another one, that's what it's for. Veteran technicians will look at the printer with suspicion, used to filing metal by hand. But when they see that a conveyor belt bearing is manufactured while they have coffee, they even ask for a colored filament. 3D technology doesn't replace experience, but it prevents the technician from ending up talking to themselves in front of a machine that's down on a Friday at six o'clock.
