Parchment Paper Paired With 3D-Printed Grid Gives a Nice Glow

A custom enclosure for an RGB LED matrix utilizes a 3D-printed grid and parchment paper to create a smooth, pixelated display.

The design features a 3D-printed grid that acts as a light blocker for each LED, preventing light bleed between adjacent LEDs. This grid was created by utilizing slicer settings to print a flat square with a grid pattern infill and no solid top or bottom layers, effectively generating the grid structure.

Finding an economical diffuser solution proved challenging. While professional diffuser films and acrylic sheets exist, a household DIY option was sought. Plain white paper blocked too much light, and wax paper had poor handling and off-angle viewing. Parchment paper was found to be the optimal solution due to its thinness, ease of handling, even color, and sufficient opacity for diffusion while allowing adequate light transmission.

The final assembly involves layering the 3D-printed grid over the LED matrix, followed by parchment paper, and finally a sheet of clear plastic. The article notes that achieving effective light diffusion in DIY projects can be difficult and suggests this method as one of many potential solutions.
