Actually... for once... I disagree
Kitchen printing is one useful application for a domestic 3D printer. For once.
There is no requirement for robustness, as long as it hold together until it is moved to the dining table it is OK and at the end of the day it will be eaten anyway. That is a much better scope/niche for 3D printiing compared to people trying to do DIY and print spare parts. Printed replacement for a gear sprocket? Printed replacement for a gear level? Printed replacement for a valve? No thanks. Rather not.
Printed "To the best mum" on a cake for mum's birthday? Why not if you have the money to waste, end of the day it costs less than a full set of celebrity cook endorsed kitchen tools.
