By applying 3D printing, Roy eliminated most processes involved in the creation of the insole. The Raise3D N2 is able to directly build a final production model with customized insole geometry and will automatically leave the space and slot exposed for circuit setup. After installation, the printer will completely enclose the electronics by printing the consecutive layers over them. Labor cost, facility and equipment cost, and lead time are shortened by this automation. Most importantly, his Raise3D printer allows him to combine insole customization and circuit setup together in one print run. As a result, the price of the insole is reduced to 500 HK dollars from 100,000HK dollars. Lead time is reduced from 2 weeks to less than 5 days. The equipment required is reduced to a computer, scanner and printer instead of a foam pad and thermoforming machine and grinding machine.
