Rest Devices has the goal of creating a nursery in the age of the smart devices. One of their big products, Mimo, is a wearable device for infants that monitors a baby’s sleep patterns, breathing, and movement, and updates the parent on their child’s health through a smartphone app with live data. Always pushing products forward, quickly prototyping, and developing novel concepts to improve the lives of parents tending to their children, the company’s entire design to product stream is kept in house. They design, they prototype, and they even make their own manufacturing equipment for their products. They keep everything in house to easily make changes to improve their customers’ experiences, and as a result the company is always on the lookout for new products to increase their product development efficiency. The Mimo baby sleeping monitor all depends on a small, plastic turtle. Housed inside this plastic sea creature are the brains of the product, a sleep and breathing monitor that sends information and alerts to parents. But their existing manufacturing solution quickly became a manufacturing nightmare when the force of the automated press started to crack and break the molds, producing unusable products. With product deadlines to meet and a broken machine, they needed a much faster and much cheaper solution.


Using the Mark One, Rest Devices 3D printed molds that resisted the force of the press and improved product consistency. Very quickly, Rest Devices could make up for lost money and time from their broken machine. The printer’s strength, capabilities, and quality were able to help Rest Devices pull through and fulfill the promises they made to their customers. The Mark One was an instant hit at Rest Devices, allowing the company to prototype strong parts without the fear of operation complexity on a milling machine or the price and lead time of a third-party manufacturer. The Mark One has exponentially decreased prototyping time and costs at Rest Devices, improving company processes in almost every aspect of their design and manufacturing stream. This has made their 3D printed wearables transition from prototype to reality even faster. With a critical manufacturing problem solved, Mimo now focuses on using the Mark One to speed up their prototyping process and is even exploring the possibility of printing end-use parts for greater control and customization of their expanding product line.


  • Reduced cost of prototyping by 90%
  • Reduced time to prototype by 85%
