Riven’s quick re-scaling tool

Auto sales finally got back above pre-recession levels in 2014 with August sales reaching a seven-year high. After six long years, sales levels have matched 2007’s pace. More importantly, several research groups expect 2015 continue to grow. Today’s Motor Vehicles allows marketers direct access to this healthy industry with continued growth.

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.
