An auto-curing chamber for SLA prints

  • Posted by admin on July 4, 2018

If you have a 3D printer, it’s probably the fused deposition modeling (FDM) type that deposits melted material onto a bed, eventually building up whatever you had in mind. Stereolithography (SLA) printers, however, work in the opposite way using light to solidify liquid material, which is then pulled out of a vat. 

While an interesting process, one consideration is that after generating the print, materials, especially those that are biocompatible, must be left alone under the proper light and temperature conditions in order to solidify fully.

To help with this task, makers at Fablab Irbid designed their own Arduino Uno-based “Post-Curing Box.” It features UV LEDs and a rotating platform, along with a temperature sensor for monitoring conditions. Brightness, rotation, and cure time are set with a simple user interface consisting of an LCD screen, knobs, and buttons. 

This project not only produces ideal conditions for finished parts, but certainly helps with the temptation to poke around—especially since you can see in with its partially translucent viewing window!
