Many issues can arise for 3D-printed parts with physical threads, leading to unusable designs and subsequent prints. Threads without appropriate clearance often cannot be assembled as intended once printed.   

Two new options have been added to the “Thread” command to help users define physical thread clearance when designing parts to be 3D printed. These new options allow users to enter additional clearance values by percentage orby an absolute value. The thread’s internal diameter will be increased, or the external diameter will be reduced by the percentage of the nominal diameter or absolute value. Clearance values vary by the material, process, and 3D printer.
