I've managed to print a prototype of a kitchen that fits onto a shelf of my bookcase: 56 cm width, 30 cm depth and 25 cm height.
I've printed out the kitchen blocks and cupboards on a Felix 3D Printer version 3. Used filament: PLA. I used a special version (for this 3D printer) of the Cura Engine to slice the objects with 24 % infill, printed with 55 mm speed and normal quality.
Average printing time for each block or cupboard: 10 to eleven hours.
The small attributes I added to this kitchen were printed with my UP! Mini 3D printer in ABS plastic.
