This course teaches dynamics, one of the basic mechanics subjects of Mechanical Engineering. Students would be able to organize their knowledge about force and motion, work-energy, impulse-momentum in view of Newton's 2nd law and its integration over time and displacement. The Engineering Dynamics consists of two parts: particle dynamics and rigid body dynamics. This is the … [Read more...] about Particle Dynamics

Material Jetting and Stereolithography
This course looks at two photopolymer resin-based processes: material jetting and stereolithography. We walk through the build preparation, printing, and post-processing for both processes, and discuss the kinds of applications for which these processes are well suited. The necessary elements for each course are lecture videos, knowledge checks, and project completion. For … [Read more...] about Material Jetting and Stereolithography
Shape and Property Control of Metals I & II
This course introduces students to the basic concepts of shaping materials and their impacts on properties and structure. An introduction to the fundamentals of diffusion in a solid follows. We present different types of diffusion mechanisms and their dependence on temperature. The role of dislocation on mechanical properties and how it can be used to strengthen materials … [Read more...] about Shape and Property Control of Metals I & II
Material Extrusion
This course is a deep dive into the most commonly used method of additive manufacturing: material extrusion. We specifically examine the fused deposition modeling process, and then look at the related composite extrusion process which can extrude a continuous fiber (such as carbon fiber) along with a thermoplastic. The necessary elements for each course are lecture videos, … [Read more...] about Material Extrusion
Design for Additive Manufacturing
Should a part be made with additive manufacturing? If so, what process should one select, and what design choices should one make? This course seeks to answer these questions by providing a framework called the DFAM staircase, and by providing a scorecard for assessing appropriateness for additive manufacturing. The necessary elements for each course are lecture videos, … [Read more...] about Design for Additive Manufacturing
