Mentoring students in 3D printing

I taught for 3 academic semesters an introductory course on CAD design using PTC Creo 3.0 for a total of little bit less than 300 students. These are some of the projects that my students designed in CAD and built prototypes using 3D printers. I was fortunate to mentor very smart students with some very interesting solutions to everyday problems as you can see in the slides below. Triangle [Read More]

Combustion Chamber

I designed a combustion chamber with optical quart glass access and instrumentation ports for my research during graduate school. The chamber had to be leak proof in vacuum and when pressurized up to 200psig. Previous design were complicated with many parts, so the new design was simplified to have 3 main blocks bolted together and housing the quart glass as seen in the CAD model below. CAD drawing of main chamber showing 3 blocks and quartz glass: I decided to go with stainless steel material SS304 for its low thermal conductivity, high strength, and good corrosion properties.
