Pond Springs Elementary School Students love guessing what the 3D printer is printing! Last year, Ms. Cook and Ms. Shipp’s 4th and 5th SWEET group built a 3D printer from a Makerfarm Pegasus kit. Now, that printer is in the library window, and students love to stop and watch it as they go to and from class. Next time you are at school, stop by and guess at what is printing!
