Top new features in Simufact Additive 3.1

Orientation assistant to determine the best build orientation

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:

  1. Support area
  2. Support volume
  3. Projected area
  4. Design height
  5. Local minima

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.

Automated distortion compensation

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

  1. select the function and
  2. specify the tolerable deviation.

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.

 

Identification of manufacturing issues

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.

  • Recoater Contact: It indicates the probability of contact between recoater and part.
  • Possible Part Failure: A traffic light system indicates how likely it is that the part cracks while printing.
  • Layer Offset Intensity: During the printing process it is possible that a layer offset occurs. The layer offset is a change in the powder bed which can lead to a surface defect of the part. Employing this function helps the user to identify critical areas of the part.

Particle tracking to create history plots and advanced path plots

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.
