The job of a computer technician involves repairing hardware that is sometimes no longer manufactured. 3D technology makes it possible to create spare parts, brackets, or custom casings. For example, if a laptop's anchor clip breaks, an exact replica can be modeled and printed instead of searching for an impossible-to-find replacement. The necessary programs are modeling software like Fusion 360 or Blender, and a slicer like Cura or PrusaSlicer to prepare the file for the printer.
Rapid Modeling for Hardware Solutions 🛠️
For part design, Fusion 360 allows creating geometries with precise tolerances, ideal for mechanical fits. A technician can scan a broken connector with a reference camera and model a mounting base for a graphics card. Tinkercad is a simple option for beginners. Printing in PETG or ABS offers thermal and mechanical resistance. With a 200-euro 3D printer, adapters for power supplies or brackets for hard drives can be manufactured without relying on external suppliers.
The Day I Printed a Mouse and It Worked 🖱️
A client brought in a gaming mouse with a sunken left click. Finding the original part was like looking for a needle in a junk haystack. So I modeled a button cover in PLA and printed it. It was a bit crooked, but the client said it gave it a retro touch. Now, every time a keyboard fails, my boss looks at me and says: Are you going to print another invention?. And I'm happy, while filament dust accumulates on my desk.
