Our club currently has two 3D printers. The first one is a Flashforge Creator. We received it as part of a generous grant from Monsanto's Grow Rural Education grant. It is a dual extrusion printer with a heated bed. It prints in either ABS or PLA plastic.
The second printer we just received as part of a grant from Ekocycle and the FIRST robotics program. It is also a dual extrusion printer but it prints in PET plastics. The plastic for this printer is partially created from recycled pop bottles!
Our students have printed all sort of interesting things. They range from rings to cell phone cases. They have designed unique objects and one student is currently working on printing a model of some industrial equipment for a area company to use at trade shows!
