3DSIM has just announced beta testing of its additive manufacturing (AM) simulation software exaSIM. This cloud-based 3D printing computer-aided engineering (CAE) tool will help metal sintering users preview how their designs will distort and handle residual stresses.

“Were using advanced computational solvers to predict residual stress and distortion in a layer-by-layer fashion,” said Brent Stucker, chief executive officer and a cofounder of 3DSIM LLC. “exaSIM Beta offers two operational modes for predicting distortion and residual stress. A third mode will be introduced during the course of the program. All modes can be used to generate supports, conduct trend analysis, and ultimately, reduce the likelihood of build failures.”

Using these predictive algorithms, 3DSIM hopes engineers will be able to reduce the trial and error associated with 3D printing. The goal is to print designs right the first time, thus accelerating time to market. As the beta program progresses, 3DSIM will add physics and optimization features to the solver.

“Our vision is focused on moving the manufacturing industry away from reliance upon costly experimental testing toward predictable, safe and timely production. We see exaSIM as another step in advancing AM toward its true potential,” added Stucker.

Beta users for exaSIM will be able to choose between Basic, Advanced, Complete and Enterprise versions. It seems odd for 3DSIM's marketing team to name one of its products ‘Complete’—perhaps unintentionally implying that the Basic and Advanced versions are somehow incomplete. A representative of 3DSIM assures that the name might change when the Beta is finished.

However, when comparing the versions, what differentiates them is the number of users, cloud-based storage size and some functionality:

  • The ability to assess thermal strain (Complete and Enterprise versions only)
  • Scan pattern-dependent strain (not available in the Basic version)
  • Thermophysical materials database (included in the Complete and Enterprise versions but available at extra cost for the other versions)

In addition, the Enterprise version has added features that focus on technical support and training.
