Import the resin model and the FDM support model into the slicer
Align both models to the same coordinate system and build plate origin
Scale the support model to match the resin part dimensions if needed
Place the support model directly under the resin overhangs or contact points
Set the support model as a separate object or modifier mesh
Use support blockers to prevent automatic supports on the resin model where the FDM support will be used
Enable custom supports or manual support painting if available
Generate supports only for the FDM support model
Disable supports for the resin model if the FDM support is replacing them
Adjust support density, interface layers, and contact Z distance for the FDM support
Slice and preview the toolpaths to confirm the FDM support matches the resin geometry
Export the G-code for the FDM printer
Print the FDM support and use it as the physical support structure for the resin part
If needed, create a negative or mold-style support shape by duplicating the resin geometry and offsetting it in the slicer
Use mesh editing or CAD software first if the slicer cannot generate the required support geometry directly
