A-dec is an Oregon-based manufacturer of dental equipment, including specialty chairs, delivery systems, medical lightning, and supplies. They are always looking to improve the ergonomics of designs since better ergonomics results in better care and experience for patients. A-dec was no stranger to 3D printing. They first adopted traditional 3D printers a decade ago, to assist in product development. However, due to limits on speed, strength, and detail, they were forced to outsource many of their prototypes. When they adopted HP’s full-color solution, they first used it for prototypes and quickly expanded to jigs, fixtures, and assembly aids. They were impressed with the improved surface quality, mechanical properties, and speed. But another important characteristic was the geometric tolerances, allowing assemblies to fit together accurately. Initially intended for only prototypes and tools, engineers began to see the machine’s potential for end-use parts. They started to make replacement parts for their subtractive machines. On older subtractive machines, replacement parts may not be available from the OEM, which requires costly outsourcing. This was also the case for a customer’s dental machine. The customer needed a replacement part for a 20-year-old dental unit. Previously made by vacuum forming, the tool to create this part had been destroyed [...]
