I’d like to print 3D models produced by Altium (Electronics CAD software) - the output is a STEP file of the PCB with component objects placed on it. The bodies of these components often sit slightly proud of the PCB meaning there’s many floating “Blocks” that are only inreconnected by the fine legs of the components . PreForm doens’t seem to recognise these gaps and lets me attempt to print the model. Often this works because the gaps are sufficiently small that the resin manages to solidify in these gaps, but it’s not guaranteed.
I’ve been trying to use SolidWorks to “wrap” the object - like the inside skin of a mold, which SolidWorks can do for single parts, but not for assemblies. My local SolidWorks support vendor can’t come up with any solution to “shrink wrap” a model so that all minor/directional cavities woud be filled-in by an outer shell/skin.
If SolidWorks is no use, what else can I look at? This is a regular workflow for me, so hand-editing dozens/hundreds of components each time I want to print isn’t really viable - I want some automated solution.
