In Amsterdam, a 3D printed home takes shape

"In the three weeks since "construction" started, a 3-meter high corner of the house has been printed, reported The Guardian."
Typically a townhouse of this size built out of standard CMUs (concrete blocks) would have had all the block work completed and might even be "dried in." The economics of this on site 3-D printed plastic concrete block/mold exercise are... terrible. There are already injection foam block/mold poured concrete systems available - but also not competitive. Petroleum based plastics (even bio-plastics are petroleum dependent at scale) are only going to become more and more expensive and less competitive as major construction components - as peak oil begins to exert its economy altering effects.
Living in a house made of plastic sounds as inviting as as living in a greenhouse - will it not be too hot ?
Kind of why houses are traditionally made of brick, concrete, stone, steel, wood etc. with assorted covering and insulation material's similar - certainly not plastic, apart from roofing sheeting between the tiles/slates and the woodwork structure of the roof.
Like Drones, EV's, Wind Turbines, someone always takes it waaayy to far, and into the realms of stupidity.
Some of the 'solutions' 3D printing has been attached to of late are ridiculous, as modern industrial polymer injection moulding, carbon fibre or traditional construction methods will win on cost, speed, and I think probably overall longevity of the end material in many of this scenarios.... in the same way laser printing after several decades, is still hugely more expensive/troublesome, than traditional bulk printing methods - newspaper, magazine, pamphlet, books etc.
@Neil Postlethwaite @dduggerbiocepts Whatever the economics of laser vs traditional printing might be, printing businesses are an endangered species because the overall cost of of printing in house is often lower than it is for outsourcing that function. This is happening in parallel with the trend towards outsourcing as many functions as possible.
Depends what you are printing - the kit a print bureau has whether digital or litho presses, and the collation, cutting and binding equipment and the economies of scale will win out for the foreseeable future. Just try and print some brochures, raffle tickets, or some internal magazines and you'll see costs of materials and your time expended towering over the costs of a bureau/printer, unless you have an in house print shop..
