DLP Projector UV Filter Removal Guide

Increase the UV output from your DLP projector by nearly 3 times with this simple 5 minute modification. Most people may not realize that there DLP projectors have multiple components that filter UV light. In this guide I'll show you how to remove the strongest filter (the one directly on the halogen lamp).

This is applicable for anyone with a DLP style 3D Printer or anyone wishing to do PCB fabrication with adhesive UV sensitive masks. It literally only takes a few minutes and significantly increases the UV output from your projector.

DLP Printers use UV light from a halogen bulb with a DLP projector to cure resin layer by layer until a 3D part is produced. DLP Printers tend to print fast than FDM or Laser based SLA printers because they can cure an entire layer at a time. However DLP Projectors are not designed for UV output and the standard UV output from an unmodified projector is much lower than the actual UV output from the halogen bulb. Therefore to optimize the performance of your DLP Printer a few modifications to its DLP Projector are necessary.
