The Optimize workflow

Let SmartSlice automatically determine the ideal print settings.

The Optimize operation takes Validate to the next level. Instead of evaluating part performance using a single print setting configuration, Optimize treats the print settings as variables and iterates through many different print setting configurations with the objective of meeting the user-defined requirements while minimizing print time and part mass. Since there are many solutions that must be computed, an Optimization takes more time to complete. In general, Optimize takes between 10 minutes and 1 hour to complete, with some models requiring more time.

Optimize is a powerful tool for automatically optimizing print settings to meet structural performance requirements. Sometimes, it is not possible to meet the requirements because the part, even when printed as a solid (100% infill) is simply incapable of meeting the requirements. In this case, the requirements should be adjusted. If the requirements can not be adjusted, then the geometry should be changed.

The general steps for Optimize are:

  1. Open your slicer and import the part geometry.

  2. Select the material and adjust the print settings as desired.

  3. Select SmartSlice and define the load case by selecting the anchor and load surfaces and define the load magnitude(s) and direction(s).

  4. Define the SmartSlice Requirements, which are the minimum factor of safety and the maximum deflection. These are the targets that the optimization algorithm aims for when adjusting the print settings.

  5. Click Validate and wait for the solution.

  6. Compare the computed values for max deflection and minimum factor of safety to see if the part is over-designed or under-designed.

  7. Click Optimize and wait for the solution.

  8. After the solution completes, a list of viable print setting configurations will be presented in a table. Hover the cursor over any solution to quickly see the print settings for that solution. Some solutions use modifier meshes. Slice the part to review the internal structure.

  9. If desired, select an alternate configuration from the SmartSlice table or results and repeat step 8. If satisfied, print the part.

See the Optimize tutorial for an example.
