The new orientation assistant supports the user during model set up. This new function offers a striking view of the build orientation, which makes the evaluation easier and more intuitive.
This function is based on 5 criteria, which are balanced among each other:
Users determine the best build orientation by selecting one or more criteria which are most suitable for their process. The assistant displays the results for the component alignment in the form of a sphere. The colored illustration (green to red) shows the user how good or bad the component alignment is within the selected criteria. By clicking on the sphere, the part is automatically rotated in to the corresponding build orientation. This interactive and intuitive handling enables the user to get a preview of the build orientation. It is also possible to use this functionality with multiple parts, but the user needs to adjust every single part.
The automated distortion compensation helps users to optimize the distortion of the part and save time even easier and faster. Two steps need to be taken beforehand:
The user must
Once this is done, the software automatically calculates the deviation of the manufactured part to the initial part – based on a “best fit method”. This process is repeated several times. After 3-5 iteration steps, the user receives a geometry that shows minimum deviations to the initial part. Simulations with multiple or complex parts are possible as well but naturally will need more time.
During the deviation calculation the user is still able to work on additional projects in the software.
This new feature is essential since virtual distortion compensation replaces time consuming and costly try-outs.
This function consists of three methods that support the user while evaluating the results. Overall, all three functions enable the user to identify critical areas in the part.
Particle tracking to create history plots and advanced path plots enables the user to identify the material properties and material states in the different layers of a printed part over time. Applying the powder bed layer by layer can cause changes in the underlying layers due to heat influences of the laser. These can now be visualized with the particle tracking. In addition, a path plot function is available which allows the user to plot results not over time but over the distance between the particles.
In addition to the proven pure mechanical inherent strain method Simufact implemented in version 3 a thermo-mechanical calculation method. The build process is simulated layer wise by a thermo-mechanical method. It allows users to make statements at an early stage about global thermal behavior in the part, for example, to detect thermal peak loads. This method is physically more comprehensive, since real machine parameters are used, including thermally relevant parameters such as laser power, laser speed and predetermined temperatures in the construction chamber. This brings the simulation closer to the familiar manufacturing process.
During the additive manufacturing process, distortions and residual stresses occur both in the workpieces and in the base plate. The latter can affect the properties of the support structures and the component. With Simufact Additive 3 you can determine the influences of the base plate. As a practical application, the user for instance may determine when the base plate has become too thin and an exchange is required.
Simufact Additive 3 offers a Linux solver in addition to the Windows Solver. Thereby the software is now available for simulations on Linux computers for instance on high performance Linux clusters. The operation of the software through the GUI continues in the Windows environment
In practice, several geometries are usually arranged and printed in the build space simultaneously. With Simufact Additive 3, the user quickly and easily models the thermal printing process of several geometries in the build space and recognizes at which point the components influence each other.
In Simufact Additive 3, users can compare simulation results and reference model (e.g., CAD data) by mouse click using "best-fit" positioning. In the best-fit method, the software automatically determines the position at which the deviations are lowest. The visual presentation of the results, based on measurements, allows the user to quickly assess whether the deviations are within the permissible tolerances. For this function, Simufact has integrated Hexagon's 3DReshaper technology.

Simufact Additive 2 provides special handling to determine the most efficient positioning of parts on the base plate and allows for iterations to be made that optimize the build-up-orientation. Positioning the part is very intuitive, due to the easy-to-use-interface.
Simufact Additive 2 takes into account orthotropic material properties, which enables a more realistic representation of support structures stiffness. Coarser meshing provides reliable results with a simultaneous reduction of the required calculation times.
An effective, fast optimization of the entire process chain, including printing, heat treatment, cutting/removing of supports, and HIP. With Simufact Additive 2, users are now able to stop and re-start the simulation process at any stage of the process chain. Each process step can be optimized separately based on the previous results. Simufact Additive 2 further shortens the simulation calculation times.
Simulating the HIP process (Hot Isostatic Pressing) in Simufact Additive 2 now includes the parts porosity and its densification – based on the hollow-sphere model. The component density affects the product lifetime, which can be significantly longer, the less porous the work piece is.
Simufact Additive 2 enables users with a comparison of simulated parts with the target design or 3D measurement data as a reference. Users can also evaluate deformations relative to the reference geometry. Users can measure the actual part and import the results into Simufact Additive. This ultimately provides engineers with an easier way to compare their results, which ensures a more efficient workflow.
