After many months designing and redesigning multiple times, the team was able to solve the compatibility issues. The last step was to pass the UL certification, which tests for the safety and compliance of the machine with US and international laws. To help speed things along, the team had the boards tested for standard electromagnetic conduction compliance by an outside lab. The results came back positive, and the boards were sent to UL. Running a more in-depth test would have taken too long, so the team, confident with their success in the tests so far, moved forward with the certification. Unfortunately, the results from the FCC requirements, which were more stringent than those tested, were not met by less than 5%. It was time to go back to the drawing board one more time.
After a few more weeks of trials and errors, the team was finally confident enough to try again with UL. The printer was sent for testing on March 29, 2018, and testing began immediately. The following week, the results finally came back, and allowed the team a deep sigh of relief. The printers were finally fully compatible and fully certified.
This certification starts the final stages required to move forward and begin the final production of the printers for Kickstarter Backers and Pre-Order Customers. The boards will be produced following the latest design and then installed into the 20,000 already-assembled printer bodies. Then, it’s just a matter of getting the orders packaged and shipped to those who have been patiently waiting.
