We want to make sure that all of our products live a long, happy life. To get there, we designed tests that pushed every major component in our 3D printers to its physical limit. Each of the 50+ components that make up a Formlabs 3D printer were put through the equivalent of 36 months of regular operation. This meant over 2 million cycles of machine parts sliding, turning, peeling, hoisting etc. All of our components had to survive this endurance test before they were considered. It’s important to note there are many factors that affect both the calculated and actual lifetimes, so lifetime can vary from printer to printer.
