3D printing for programmers: more than a geeky hobby

Published on May 16, 2026 | Translated from Spanish

3D technology is not just for industrial designers or makers. A programmer can use it to visualize complex software architectures, create prototypes of physical interfaces, or even generate custom work tools. For example, a virtual reality programmer can print a mount for their eye-tracking sensors, saving time and money on commercial parts.

A programmer holds a 3D-printed mount for eye-tracking sensors, next to a monitor displaying a complex software architecture.

How to integrate 3D into your development flow 🛠️

To get started, you need modeling software like Blender (free) or Fusion 360 (with an educational license). Then, a slicer like Cura or PrusaSlicer to prepare the file. The typical workflow involves designing a part that solves a physical problem, such as a mount for your development camera or a cable organizer for your desk. Finally, you export to STL and send it to the printer. The result: less time searching for parts in stores and more time debugging code.

The day I printed a keyboard and almost cried 😅

I decided to print my own mechanical keyboard. After 30 hours of printing and 200 grams of filament, I discovered the keys didn't fit because I measured the microcontroller pins wrong. Now I have a keyboard-shaped paperweight that I use to hold cables down. Moral of the story: programming is easy, measuring in millimeters is where the drama begins. But hey, at least I learned how to use a ruler.
