Case Study: ZetrOZ achieves rapid, production-quality redesign of the sam ultrasound device with 3D Systems' ProJet 5500X 3D printing

ZetrOZ Reduces Product Time-To-Market With MJP Multi-Material 3D Printing

ZetrOZ, a privately funded medical device startup of about 20 employees, developed sam® (Sustained Acoustic Medicine), the world’s smallest FDA-cleared ultrasound therapy system for drug-free pain relief. After a year on the market the company needed a more attractive, comfortable and rugged consumer-ready casing that could withstand drops, dirt and everyday home use.

ZetrOZ partnered with the Connecticut Center for Advanced Technology (CCAT) and used the ProJet 5500X multi‑material 3D printer to produce realistic, over‑molded prototypes (rigid cases with soft grips) in about a week per iteration. The rapid, low‑cost prototyping—allowing multiple design concepts and material tests—yielded a refined, durable design slated for early 2016 release and accelerated the product’s development compared with traditional molding methods.
