3D-printed part re-scaling tool

Recognizing that all 3D printed parts shrink or warp during the printing process, Riven is introducing a new re-scaling tool that makes it easy to print parts more accurately. Riven’s software automatically computes re-scaling factors as compared to the original CAD. All processes, from FDM through metal 3D printing, can be made more accurate with quick 3D re-scaling. Unlike checking limited dimensions with calipers or a CMM, Riven uses a full part capture to compute an optimal solution based on the entire part shape to produce a more accurate result. 

It takes only minutes for Riven’s quick re-scaling tool to create results with clear indications of the location and degree of variance from the intended design.

Quick re-scaling result on the left for a first FDM part clearly shows the problem areas. After applying Riven’s re-scaling factors, the CAD-compare result for the second printed part on the right shows that it is more accurate with deviations reduced significantly in critical areas.

Once Riven’s software has checked a test part, new parts can be quickly adjusted using the established re-scaling factors. This technique can be used for FDM, resin-based printing, powder bed fusion, and most metal 3D printing.

New parts printed with the benefit of Riven’s re-scaling factors are more accurate on the first try. The part shown below had deviations relative to the CAD model reduced by a factor of 4.

Fast 3D re-scaling data can save hours, iterations and costs and produce significantly more accurate parts. With only a few minutes for a quick scan and automatic CAD-compare, Riven keeps your projects running smoothly even when you change materials, settings or print in a different location in the print volume. Riven’s re-scaling tool can even be used to calibrate the entire build volume for binder-jet and other professional machines.
