Building 3D printers is complicated. Many different systems (optical, mechanical, electrical, and chemical) need to work in harmony to create high-precision 3D prints on your desktop. In this talk, Dávid Lakatos, head of product at Formlabs, discusses the makings and testings of the Form 2 desktop 3D printer. From putting the machine through the equivalent of 2 million cycles of machine parts operation, 36 months of regular operation, and dust conditions of the Sahara Desert, Lakatos details the many processes and behind-the-scenes in designing for quality and reliability for 3D printing.
