I had the privilege to see one and get parts printed with it...
At home it does not make much sense, because of the heat-up and cool-down times, the fact that printing a single small part will not only take longer and cause more garbage (as not all material can be recycled)...

The ceramic powder printers with inkjet won't have the heat/cool issue but even with modern curing resins can't be as thin and flexible as plastic parts. Their benefit is the possibility to print color models and cheap powder (in case of DIY projects).
Fun fact: Even some commercial power printers use HP inkjet catridges.
