Is it possible to produce 3D printed optical lenses with a 3D printed lens grinding machine?

In this video I show how to produce 3D printed optical lenses in relatively good quality. I have designed and built a 3D printed lens grinding and polishing machine. With this machine it is possible to grind and polish 3D printed optical lenses precisely. I show some experiments to find out the focal point. I measure the transparency of the lenses with an Arduino and a photoresistor and build a simple magnifying glass. With the lenses it is possible to build simple telescopes, magnifying glasses or many other optical devices. I show all experiments and exact details about the production of optical lenses on my website: https://fraensengineering.com/how-to-... 👉 Follow me on Instagram for exciting updates, projects, and insights:   / fraensengineering   If you would like to carry out optical experiments yourself, you can download the files here: https://www.etsy.com/at/listing/16071... or here: https://cults3d.com/de/modell-3d/werk... 🔽If you would like to support my work: 👉 www.https://buymeacoffee.com/fraensengine...
