Volume Graphics’ Version 3.5 is said to improve non-destructive testing, analysis, and geometry repair of parts made by injection molding, casting, or 3D printing

May 10, 2021

CHARLOTTE, N.C.—Particularly in the automotive, aerospace, and defense industries, engineers who are exploring novel materials and manufacturing methods are increasingly turning to computed tomography (CT) scanning to achieve a more accurate, non-destructive evaluation of product robustness and performance. The latest version of Volume Graphics’ high-end CT data analysis software suite, version 3.5, is reported to enhance manufacturers’ capabilities for inspecting parts and improving designs—however they are made.

Volume Graphics is a developer of software technology that interprets CT data from scans of almost any material to detect, analyze, and visualize minute structural deviations that might affect part quality. For more than 20 years, the company has been developing software for non-destructive testing based on industrial CT. Customers around the world—from the automotive, aerospace, and electronics industries—use Volume Graphics software for quality assurance in product development and production.

Volume Graphics’ Version 3.5 is reported to provide more powerful, automated design-geometry adjustment and repair tools that can be used to correct and offset issues stemming from the manufacturing process itself. Moldmakers, casting shops, and additive manufacturing (AM, also known as 3D printing) providers can employ the software to detect and visualize material and design defects or distortions. They can then employ sophisticated capabilities to correct their CAD designs, compare values against nominal limits, and ensure that final part quality meets applicable industry standards, Volume Graphics said in a release.

Version 3.5 of Volume Graphics’ CT data analysis software suite includes VGSTUDIO MAX, VGSTUDIO, VGMETROLOGY, VGinLINE, and myVGL.

A completely reworked manufacturing geometry correction module

 The software module is said to benefit all those who work with a mold, including injection molders or casters. Enhancements in usability, with continuous updating and feedback on quality, give the CAD designer valuable information that can be used to improve manufacturability. Filtering out points that can cause erroneous compensation results, the software fine-tunes surface fitting and provides compensations that are within tolerances. Users  can immediately see if their design changes are compatible with mold-making, the company said.

Enhanced mesh compensation

 For those working in simulation and additive manufacturing/3D printing, the module is said to provide easier navigation and understanding of the relationships between elements for better interpretation of part warpage, deformation, and displacement. It also automatically compensates designs to correct for such deviations from manufacturing intent.

Mesh updating is reported to be 10 times faster, with improved results when scan and reference objects differ greatly in size or show other significant deviations. The module also provides a greater number of control points, allowing for more granular and accurate results. In the case of lattice structures and other complex geometries, a uniform control-point placement function ensures full analysis of a design. The software can also shorten the 3D-print-and-test process by automatically running two sequential design-compensation results to move a design for AM closer to nominal before the first print, according to the release.

Capability enhancements support engineering across many industries

Other enhancements in version 3.5 are said to strengthen existing functionalities that support science, R&D, medical device development, and other industries in addition to automotive and aerospace and defense. Among these is advanced reporting, which is now more user-friendly and fully integrated with viewing, the company said.
