Print out a house

WikiHouse explores the idea of anyone designing a house and printing it out on a giant machine which basically takes a sheet of plywood or MDF(toxic!) and burns out shapes which you then assemble yourself. Kind of like those dinosaur things from (my) childhood, but a real-size building!!

Don't really know how liveable, costly,  long lasting, weatherproof, sustainable, sanitary etc these things would be but its a fun start!
