Rescaling tool minimizes 3D printing design iterations

Recognizing that all 3D-printed parts shrink or warp during the printing process, Riven has developed a new rescaling tool that reportedly minimizes design iterations and yields more accurate parts. The tool works with AM technologies ranging from FFF and resin-based printers to most styles of metal printers.

The California company’s software automatically computes rescaling factors by comparing a printed part to the original CAD file. The rescaling tool generates data in minutes that indicate the location and degree of variance between the printed part and the part design. Once the software has checked a test part, the design for subsequent parts can be quickly adjusted to correct flaws.

The deviations between the part shown above and its CAD model, for example, were reduced by a factor of four.
