Calling it a resin printer is like calling a FDM printer and injection molding machines in the same category, both can melt ABS but the way they work and capabilities are completely different.

Same thing here hardly anything common with hobbyist resin printers beside using some kind of UV curable resin. And as with other 3d printing technologies Stratasys is decade ahead in terms of research and commercialization sitting on all the relevant patents and selling expensive machines (sometimes as a result of acquisition).

Once the patents ran out maybe there will be more advancements and general availability. Although I expect much longer delay compared to FDM and SLA/DLP 3d printers. Inkjet printing on paper is already complicated and finicky enough, It's not something a hobbyist can make from scratch in a garage. Add a resin which will by design solidify when exposed to light potential destroying the inkjet nozzles, and doesn't necessarily behave as regular ink when attempting to spray it through inkjet head and you get the need for some serious investment to recreate the technology even with patents expired. The recent hobbyist 2d UV printers are step in this direction, but commercial/industrial UV printers have existed for quite a while. To me this suggests there is additional gap in patents/technological challenges between textured 2d UV printers, and full 3d UV inkjet printing.
