Simcenter 3D Additive


Simcenter 3D Additive

Additive manufacturing (AM) is changing the way products are made. New revolutionary machines and processes are rapidly pushing AM from the prototype environment onto the production floor. The additive manufacturing capabilities in Simcenter™ 3D software are used to predict distortions and defects before parts are printed, thereby reducing the number of test prints and improving the quality of the final print.


High-quality simulation environment


The high-quality simulation capabilities of Simcenter 3D are paramount to industrializing AM. During the AM process simulation, the parts are meshed accurately with tetrahedron meshes and sliced afterward, which gives better results than voxel meshes.


Enhanced inherent strain approach


A new approach was developed that was brought to the market with Simcenter 3D. The layer-by-layer build process during the powder bed fusion printing leads to layer shrinkage during the cool down of the layer. The stiffness of the printed structure has a strong influence on part distortion.


Aerospace and defense


The space industry already produces structural parts for launchers. The goal is to produce parts that are light-weight and have good mechanical properties. The airplane industry is also developing this technol - ogy, but is in more of an exploratory phase with the goal of producing components with complex geometry.


Industrial machinery


Power generation appears to be an industry that is exploring AM to produce turbine blades and other combustion chamber components. AM can also be applied to repairing existing turbines.


Automotive industry


Lightweight structures for racing cars and completely new bionic designs can be manufactured with additive manufacturing technology. Generative design can be used to find new proposals that can be manufactured with additive manufacturing technology.



Providing a platform for multidiscipline simulation


The Simcenter 3D AM solution is part of a larger, inte-grated multidiscipline simulation environment with Simcenter 3D Engineering Desktop at the core for centralized pre -/postprocessing for all Simcenter 3D solutions. This integrated environment helps you to achieve faster CAE processes and streamline multidisciplinary simulations that integrate additive manufacturing with any of the Simcenter 3D solutions, such as thermal mechanical, vibro-acoustic, or other more complex analyses.


Industry applications


Today, AM is still mainly a research and development (R&D) activity as this process remains expensive and slow, preventing its use for large projects such as in the automotive industry. However, some industrial applica-tions are already linked to the printing of complex parts, which are difficult to produce by traditional methods. The primary goal is to create parts that are lightweight and have good mechanical properties. Repairing parts previously produced by traditional processes can also be a valuable application of AM due to the unique nature of each component.

Simcenter 3D Additive Manufacturing


Simcenter 3D Additive Manufacturing simulates the AM process for selective laser melting (SLM). The setup from a part in the built tray, including support struc-tures, is used as a basis. The user selects the parts to simulate and define printing process parameters (mate-rial, number of parts, layer slicing, laser parameters, etc.) and run the simulation. The result is the tempera-ture distribution and distortion of the part.
