This 3D printed window decoration celebrates all thing rainbows and prisms with the use of a magical material called diffraction grating.
Diffraction grating is a plastic film that is able to act like a prism which separates the wavelengths of light being emitted from a white light source (like the sun or very bright incandescent lightbulbs). There’s actually a pretty good chance you played with this stuff in a grade school science class when you were learning about the physics of how light travels. For this project, it gets used to create a geometric sun-catcher that can hang in a window or on a porch with spotted shade.

Diffraction grating – I didn’t know much about how to buy diffraction grating but after some outreach to friends, I was directed to the folks over at Rainbow Symphony. (https://www.rainbowsymphonystore.com/) They worked with me a lot to answer my heap of annoying questions and when I said I’d be publishing this project on Instructables, they said I graciously included this promo code for others who may want play with diffraction grating – AUDREY15 – I used their 13500 line film.
3D printing filament – https://amzn.to/2HQ5Yjy – I used clear, but also liked the way it looked with black and ‘marble’.
Fast tack flexible bond glue – https://amzn.to/2STV4zB
Glue syringes – https://amzn.to/37MIqXe – a necessary item for precision glue application.
3D printer – https://amzn.to/37TUGoS – I use a heavily modded Monoprice Maker Select Plus. One day maybe I’ll make a video about all the work I’ve put into it, next time I’ll just buy a fancier printer.
Desktop cutting machine – https://amzn.to/38T0mRb – I use a Silhouette Curio
Binder clips or small A-clamps – https://amzn.to/38YpQwE – for holding glue-ups.
