What 3-D Printing and Design is all about!
3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the entire object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.
• Integrated with Google Classroom
• Learn 3D design with STEM project implications
Johnson Middle School has started a 3D Printing and Design class taught by Mr. Coatney. Besides learning the ins-and-outs of the actual AirWolf 3D printers, the different printing filaments, and the computer software, the students are learning the basics of CAD (computer-assisted drafting) and CAM (computer-assisted manufacturing). The students have been designing and printing out different everyday objects, as well as some of their own designs and creations. One of the most exciting aspects of this STEM-based class is our new affiliation with Enabling the Future (enablingthefuture.org), a non-profit organization that provides free prosthetics to people around the world. The class printed up a Raptor Reloaded prosthetic hand, assembled it, mailed it in to Enable, and have been approved to make hands for any matching recipients in our area. The original test hand will be given to a person in need, and the class is very excited to see who will get it and how it will change their life. The class also has printed and assembled a larger version of a Raptor Reloaded prosthetic hand as a sample for display, for testing, and to perhaps give to someone in need in the future. It’s a fun, innovative, and exciting time at Johnson Middle School in the 3D Printing and Design class.
