Agreed. At the end of the day, manufactured parts are driven by constraints outside of the CAD environment so analyzing 3D data as the foundation of an AI system strikes me as attacking the problem from the wrong direction. i.e. Simple optimization of a part for injection molding can take it from requiring a bunch of side actions and collapsing cores to a simple 2 sided mold and save hundreds of thousands of dollars in tooling. None of that is obvious from 3D data alone.
That said, I am excited for AI assisted CAD tools. Things like creating and applying global variables to an existing part, complex assembly analysis for part reduction or just making a starting base part can be incredibly tedious and are low hanging fruit for improving CAD workflows with AI imo.
It really depends on what your end goal & use case is. Resin printers are pretty phenomenal for any kind of product development and are very much a useful tool in the industrial design space.
That said, casual hobbyists should almost always start with an FDM (filament) printer as a first printer. Sorry to hear you had such a bad experience :/
They also use totally different mechanical concepts to move the pieces. The Phantom uses an etch-a-sketch style 2 access CNC machine with a magnet head embedded in the board (I think). For the Chessnut, each of the pieces are their own little micro robot that can drive around the board surface.
Really neat to see different mechanical solutions to the same automation problem!
