Objective:
Review the key parameters for the fixture creation step in the basic jigs and fixture workflow and how changes in their value affect the workflow.
Applies to:
- Stratasys, nTop, FDM Fixtures
Procedure:
Fixture Shape
Edge to Cavity Margin
Fixture Height
Fixture Depth
Part Clearance
Minimum Pillar Thickness
Cavity Detail
Fixture Shape
Choose between a rectangular outline or part outline shape to create the fixture design.
Edge to Cavity Margin
The offset distance between the cavity and the outer perimeter of the jig.
Fixture Height
The total height of the fixture is measured from the maximum height and the minimum height of the object. Additional height is added to the floor of the fixture to maintain the same Fixture Depth.
Fixture Depth
How deep the part sits in the fixture design space to create the jig. A larger fixture depth increases the depth of the resulting jig. Fixture depth should not exceed the total height of the input design.
Part Clearance
The clearance distance from the input part and the fixture. The clearance value should not be greater than the cavity detail parameter.
Minimum Pillar Thickness
If the bottom of your part has holes or something similar, this parameter accounts for this to avoid creating pillars.
Cavity Detail
The level of detail you want to preserve in the cavity of the jig. A lower value increases the level of detail captured but is more computationally expensive. This value should be the minimum feature size of your part. The Cavity Detail should not exceed the clearance value of the part.
