Using Smart Slice

The Validate workflow

The Validate operation computes the performance of the printed part based on the load case and the current print settings. The performance metrics are the maximum part deflection and the minimum safety factor. Validate typically takes between 10 seconds and 1 minute to complete and is therefore useful for quickly understanding how a part will perform. In a matter of seconds you will know if your part is over-designed or under-designed.

Validate is an easy method for understanding the influence of individual print settings. For example, to see the influence of the wall count, simply run a Validation with Wall Count = X and then run a 2nd Validation with Wall Count = X + 1. Compare the computed results to gain insight into how influential the Wall Count print setting is.

The general steps for Validate are:

  1. Open Cura and import the part geometry.

  2. In the Prepare stage, select the material and adjust the print settings as desired.

  3. Enter the Smart Slice stage and define the load case by selecting the anchor and load faces and define the load magnitude and direction.

  4. Click Validate and wait for the solution.

  5. Investigate the computed values for max deflection and minimum factor of safety.

  6. If satisfied, proceed to slice and print the part.

  7. If unsatisfied, have Smart Slice automatically optimize the print settings or manually adjust the print settings and run Validate again.
