Digital Fabrication and 3D Printing

The MPML manages digital fabrication resources in our Materials Teaching and Design Lab when used for research purposes. A ULS VLS4.60 laser cutter, a Minitech CNC Micromill, 3D scanners, and a suite of 3D printers with complementary capabilities: two Formlabs Form2 SLA printers, an Ultimaker 5S printer, two Ultimaker3 printers, and a Stratasys Objet Connex 350 high-resolution polyjet printer. The MTDL provides instruction and resources for students to explore the next generation of material fabrication techniques. It is also used extensively for MRSEC outreach programs, especially during the summer.
