On Wednesday, June 28th 2017, ONO received positive results from one of the supplemental tests asked of UL. In order to ensure the safety of users’ phones, additional tests beyond the minimum requirements were requested by ONO on the reliability of the ONO printing film, which separates the liquid resin from the phone. UL verified the strength and the reliability of the film over long periods of time and elevated temperatures. The film strength was tested after being held at 100C for one week, 90C for three weeks, and 82C for 8 weeks. The results were a success, showing that the film, though just 40 microns thick, is capable of stretching up to six times its length without tearing. This means that when properly applied, users’ phones are completely safe, even under extreme conditions. This is the first 3D printing film or resin tank to be UL-certified at this level.
The positive results were followed by less comforting news. Following a previous redesign for stability purposes, the new PCB boards had been sent to UL for recertification. UL identified a component that did not meet their stringent FCC electromagnetic interference standards, and pointed the team to a compliant component. The component requires sourcing, implementation into the production, and further testing by ONO, after which it will be sent back to UL for final testing. The team is expected to start shipping of all orders in 4-5 weeks.
While waiting for the results from UL, ONO has been proactive in continuing production and assembly of 20,000 printer bodies, so that once the boards are certified and ready, it will take very little time to install them and ship packages promptly.
