3D Printing Certification
The LEVEL 1 3D Printing Certificate at NAU will offer a unique experience that ranges from state-of-the-art software in computer-aided-design (CAD) and computer-aided-manufacturing (CAM), to general manufacturing and 3D printing/additive manufacturing-specific techniques. The Certificate will be a NON-credit micro-credential. The Certificate will be housed in the Mechanical Engineering (ME) department.
The Certificate starts students out in a computer-aided-design software package where they will learn the fundamentals of engineering graphics specific to mechanical design. Students will then learn about various manufacturing techniques (including 3D printing) for them to understand how to properly select the appropriate processes for manufacturing a solution. Then finally, the students will finish the certification by gaining more 3D printing-specific CAD-CAM knowledge, practice printing parts on machines at NAU, and ultimately generating a solution to a real-world problem of their own – if they wish.
How long will the certification take to complete, and when does the course begin?
The certificate coursework will occur across two weeks – one week of asynchronous/remote activities (July 15-21) and one week of in-person/on campus activities (July 22-28). Expect to dedicate 10-15hrs during the first week on your own time and 15-20hrs the second week in person – though more time may be available in the labs if needed/if wanted.
What do I need to take the course?
A computer is needed by the student along with internet connectivity to the quality needed for video consumption and file submission. For ease of accessibility during the certificate, software has been selected for ease of learning and diversity in devices that could be used. Specifically, Onshape will be used for its cloud-based CAD which lends itself well to be used on any computer, through any web browser, or as an application on devices such as tablets. Ultimaker Cura was selected for our general 3D printing CAM/Slicer needs because of its wide range of usability from novice to expert. Other CAM software may be used in the IDEA lab as well – such as GrabCAD print. If the student would like to use Solidworks and/or Fusion 360, the certificate instructor and staff will be able to support that as well. A 3D printer is not needed for this certification as students will be interacting with 3D printers on campus. But a hobby-scale printer would be a good companion purchase if the student would like to gain more hands-on learning. If desired and would like some feedback, reach out to the instructor for recommendations.
