Senior Design Team sdmay18-05 • 3D Metal Printer
Our team is working with Dr. Timothy Bigelow to create a 3D metal printer which has nondestructive evaluation capabilities. Though metal 3D printing is not novel, the act of evaluating the the printed part as it is being printed is a novel idea. Our team is building a full sintering 3D metal printer which has 3 lasers. First, there is the usual main melt laser which most all metal 3D printers have. In addition to this, there is a pulse laser and a third laser with an interferometer; these lasers are used in conjunction to perform nondestructive evaluation of printed parts.
This project is unique in that it requires a diverse range of engineering skills- there are mechanical problems, optics problems, as well as electronics and controls problems. Our team has a diverse background as well, and we are very motivated to solve all of these problems.
Currently, our team is finishing up the overall mechanical layout of the printer and deciding how all of its components are going to be controlled. As these initial designs are solidified, this page will be updated with more recent images and operation descriptions. The current CAD model of our design is pictured below.
