The Intermediate 3D Printing class starts online (through Pasadena City College Extension) on Thursday August 21st. It's entirely online, but with synchronous meetings 7-9 PM on Thursdays for four weeks. If you know what an STL file is and have some idea how to slice one to create G code, you will be fine in the intermediate class. Sign up here.
The Advanced class starts October 2nd. General information on all the Makertech classes at PCC can be found here.
And of course check out the in-store workshops at Deezmaker! Current list is here.
