Today our visitors were Peter, Dan and Priya from a PrintME 3D. First they showed us some of the things they've already made with their 3D printers, like a ukulele, the London Eye, a castle, a mini squid, and a robot hand. Then I got to use the 3D printing pen. The 3D pen is like a pen that works with white plastics that is soft when it comes out but gets really hard and sets after a little while.
I also found out about the Choc Edge. The Choc Edge is also a kind of 3D printer that make things with real chocolate so you can eat it!
This is the link to the video about Choc Edge so you can see how it works.
