Analysis TaskThe Dynardo ANSYS optiSLang ALM workfl ow enables the simulation and prognosis of component stresses caused by 3D printing, such as temperature fi elds, deformations (distortions), residual stresses, irreversible strains or pos-sible cracking.

Solution MethodologyThe workfl ow can process arbitrary geometries for prin-ting, slicing (seperation of printing layers) and thermo-mechanically coupled simulation of the additive layer manufacturing process. The entire thermal-mechanical simulation workfl ow is parametrically built. Thus, process, discretization and material parameters can be varied and made available for impact examination in sensitivity analyses or robustness evaluations. The results are then used for calibration and optimization.

SIMULATION OF RESIDUAL STRESS AND DISTORTION OF ADDITIVELY MANUFACTURED COMPONENTSParametric Additive Layer Manufacturing (ALM) simulation workfl ow for calibration and optimization of the manufacturing process with ANSYS optiSLang

optiSLang automatically identifi es the relevant input and output parameters and quantifi es the predictive capabili-ty using the Coeffi cient of Prognosis (CoP) and the Meta-model of Optimal Prognosis (MOP). Another special option of the simulation workfl ow is the implementation of an anisotropic, elasto-plastic ma-terial model for printed metals as a key to real-life residu-al stress and crack prognosis.

Customer Benefi tsVirtual process optimization using ALM simulation pre-vents time-consuming trial & error tests by:

• Prediction and minimization of residual stresses and distortion of components

• Prediction and optimization of temperature develop-ment in components and base plate

• Predicting and avoiding the risk of cracking caused by the manufacturing process

Plastic Strain

Distortion

• Simulation and target-oriented planning of post-treat-ment processes

• Optimization of process parameters, component place-ment and support structures

• Quantifi cation of risks using sensitivity analyses, identi-fi cation of optimization potential

• Coupling of component and process optimization, shortening of development times, reduction of deve-lopment costs

Dynardo supports you with over 17 years of experience regarding targeted software solutions and consulting services with ANSYS and optiSLang for additive manufac-turing.
