Additive Manufacturing Simulation

Additive manufacturing (AM) is changing the way products are made. Revolutionary new machines and processes are rapidly pushing AM from the prototype environment to the shop floor. Simcenter 3D software 's additive manufacturing capabilities are used to predict skews 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

Improved inherent stress approach

Print right the first time

Fully integrated into the NX end-to-end workflow

Providing a platform for multidisciplinary simulation

Simcenter 3D's high-quality simulation capabilities are critical to the industrialization of AM. During the simulation of the MA process, the parts are accurately meshed with tetrahedral meshes and later sliced, which gives better results when compared to voxel meshes .

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

The calculated distortions can be used to compensate the part before the printing process. The initial geometry can be automatically transformed into pre-compensated shape and replaced in the built-in tray for later analysis, or it can be sent directly to the printer to print correctly the first time.

Simcenter 3D for MA is seamlessly integrated into the end-to-end Siemens* Digital Enterprise Software MA workflow . The process is simplified to be used by non-computer-aided engineering (CAE) users as well.

The Simcenter 3D AM solution is part of a larger multidisciplinary simulation environment and is integrated with Simcenter 3D Engineering Desktop at the core for centralized pre/post processing for all Simcenter 3D solutions. This integrated environment helps you achieve faster CAE processes and streamline multidisciplinary simulations that integrate additive manufacturing with any of Simcenter's 3D solutions, such as thermomechanical, vibroacoustic, or more complex analyses.


Industry applications

Aerospace and Defense

Industrial machinery

Auto Industry

Today, AM is still primarily a research and development (R&D) activity, as this process remains expensive and slow, precluding its use in large projects, such as in the automotive industry.

However, some industrial applications are already linked to the printing of complex parts, which are difficult to produce using traditional methods. The main objective of this is to create light parts with 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.

The space industry already produces structural parts for launchers. The objective is to produce light parts with good mechanical properties.

The aeronautical industry is also developing this technology, but it is in a more exploratory phase with the aim of producing components with complex geometry.

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

Lightweight structures Generative design can be used to find new proposals that can be manufactured with additive manufacturing technology.



Simcenter 3D Additive Manufacturing simulates the MA process for Selective Laser Melting (SLM). The one-piece configuration on the constructed tray, including support structures, is used as a base. The user selects the parts to simulate and sets the printing process parameters (material, number of parts, layer slicing, laser parameters, etc.) and runs the simulation. The result is temperature distribution and part distortion.





Simcenter 3D Additive Manufacturing is used to calculate distortion of parts during the MA process. Part distortions can be transferred to the starting geometry to pre-deform it using powerful contour representation model based geometry modification (BREP) techniques. A new offset part file is generated and can be used to replace the original part in the build tray. The compensated geometry is then used for validation and can be sent directly to the printer.
