The prototype of automatic card shufflers is in the final stage prior to tool release. The larger components of automatic card shuffler are designed and assembled in detail, with the parts requiring high tolerance and high measurement accuracy when produced. With SLA 3D printing, parts cannot be printed with accuracy to perform well due to the instability of its dimensional accuracy. In the following example, the SLS technology of Nexa3D® develops and demonstrates the features of printing accuracy and durable mechanical properties.
