exaSIM™ utilizes advanced solvers to predict residual stress and distortion during metal AM production. A user supplied STL file or build file is automatically meshed and used to predict stress and strain evolution. Maximum stress components are stored and used for support generation. Users can download distortion and stress predictions along with a suggested support structure.
exaSIM™ offers three operational modes: 1) Uniform Assumed Strain, 2) Scan Pattern Dependent Strain, and 3) Thermal Strain. Uniform Assumed Strain provides the fastest approximation using an isotropic strain assumption. Scan Pattern Dependent Strain offers a higher fidelity solution by considering local scan pattern based anisotropy. Those who need a more informed answer can perform a thermal strain analysis to consider the complete thermal history, scan vector-by-scan vector and layer-by-layer. All exaSIM products are available in a secure Cloud environment. GovCloud is available for ITAR-sensitive industries.
