One of the best things I’ve 3D printed are Lithophanes. It has a magical feeling when the light shines through the lithophane for the first time after printing one. 

Lithophanes are created by converting an ordinary image into a 3D printable part. They work by varying the density of the material, depending on the grey scaling of the image. 

In short, thicker parts of the material will block more light and can be seen as darker parts on a lithophane. Thinner parts will block less light and therefor can be seen as lighter parts.

The best part about lithophanes is that you can make them of every image. You can make them with a picture of your family, your pets, your favorite Netflix series, just about everything. 

And with the help of ItsLitho, you can also do it very easily!

Up until 3 months ago, if you asked me what my favorite thing to 3D print was, I would have told you Lithophanes. However, the Coronavirus has changed that. Owning a 3D printer has allowed me to create Face Shields and give them away to our health care works who are sacrificing themselves to help us all live through the effects of the Coronavirus.

This Face Shield by 3DVerkstan, is simple to print, and uses a standard whole punch to attach the shield to the 3D print. I used some cheap transparency sheets as the shield, since they are most likely discarded after a single use.

No need to worry about it lasting a week.
