Contact Point Settings

Theoretical Background & Mechanics

The success of a resin print depends on a continuous mechanical tug-of-war. For every layer cured, the printer must peel the newly formed cross-section away from the flexible release film (FEP, nFEP, or PFA) at the bottom of the vat. The support contact points are the anchors that transmit the tensile and shear forces necessary to achieve this separation.

Mechanical Loading on Support Contacts

The total peeling force ($F_{\text{peel}}$) experienced by a layer during lift-off is a combination of multiple physical forces:

Slicer Parameters & Configuration in ChiTuBox

ChiTuBox offers precise control over how the support structure connects to the model. Understanding these parameters allows you to tune the contact interface for different resin types and model geometries.
