I don't know how much printing experience you have, apologies if this may come off patronizing, but- If the material is curing but you're not getting successful prints- if you're just getting supports or a raft, that kind of thing- the issue is with the part setup, not the printer. Part orientation, support density, support geometry, all of that is what matters. I would look at that first, because there's a very good chance a replacement printer will do no better. People successfully use even hobbyist printers to print materials that are significantly more challenging than lucitone base wrt viscosity, and all these printers more or less use the same mechanisms in the way we care about. You might need to tweak the material profile a bit if your light source is less intense than nominal, that kind of thing. But if you can print other resins successfully, you ought to also be able to print lucitone with that equipment given the right setup.
