3D Printing on Diffraction Grating Sheets

These are diffraction grating sheets and they’re are mostly used in optics.

This film can have different number lines per millimeter and this actually splits light into separate beams of color. We used the Double Axis Diffraction Grating sheet 13,500 lines/inch.

The Single Axis sheets did not transfer any diffraction features.

This stuff has tons of applications from creating laser light shows to making spectrometers.

So you can get a roll of this stuff online and use it for making DIY arts and crafts.
