Darlie develops dozens of toothbrushes every year, but many designs are abandoned due to the final effect, and only about ten kinds of mass production are achieved, resulting in a great waste of personnel and cost. Because it can only be painted by painting, some new technologies such as color separation injection and in-mold injection cannot be realized realistically on the hand board. Even if the hand board is made, the problem cannot be completely solved.

After 3DPlink uses full-color printing to help Darlie make samples, many of the designer's ideas can be quickly verified, including multi-color printing, in-mold injection and other effects can be realistic, and even print color soft and hard combination. The sample can not only verify the appearance but also further experience the touch and use effect, effectively improving the design effect and work efficiency of the R&D department.
