Tiny House 3D-Printed On-Site, Cheaply, in Just 24 Hours
San Francisco-based 3D-printing startup Apis Cor has successfully finished a residential house printing project - built in just a day, on-site, at a cost of around $10,000. The main components of the 400-square-foot-home, including the walls and partitions, were printed solely with a concrete mixture. After printing out the walls, the company's large crane-like 3D printer was removed, and contractors installed insulation, windows, and a roof. The house consists of a hallway, bathroom, living room, and kitchen and is located in one of Apis Cor's facilities in Russia. These houses could be used to help quickly re-house people affected by natural disasters.

00:00:00 [Music] this house was built in 24 hours [Music] how thanks to modern technology happy score 3d printing [Music] Happy's core building the future today [Music] 3d printing I think I've heard about it oh well but it is still expensive I
00:00:36 don't think it's possible right now but occurred yes I've heard that you can make some stuff some little stuff the house in 24 hours and no way very intelligent mode office of economic bilasa Clarkie gracias - el modo for the most vulgar a cultural experience must balance in must accessing Fringe house why not why not I think it's a good idea well it can't be
00:01:05 the same just like other houses well banana terracotta 3d forged either origami melon Cochran sounds interesting construction 3d printing and its advantages has been known for a long time but it didn't need the facilities of closed factories existing printers are big and bulky have a portal design have height restrictions or printed buildings as well as are difficult to
00:01:30 transport and assemble on site this is an expensive novelty which could never find a wide application in the construction industry these printers print only separate walls and sections of buildings and subsequent assembling is inevitable the walls of this house were printed entirely on site this is the world's first actually printed house
00:01:59 with the advent of APIs core technology construction 3d printing opens a new round of evolution thanks to the innovative design of the printer a piece core technology consists of a mobile Construction 3d printer and automatic mix and supply unit which combine to make the construction printing process as much automated as possible and almost eliminates the human factor this
00:02:25 equipment is unique and has no analogues in the world today a Peace Corps is compact dimensions high printing speed ease of transport and maximum automation of the system commissioning on-site takes no more than an hour with so many advantages the 3d printing technology easily accounted for competition with traditional methods of construction the testing was successful and the
00:02:53 technology is ready for Matthew Oh [Music] our project has been implemented at the coldest time of the year application of the concrete mixture that is used as the ink is possible at temperatures from 5 degrees Celsius above zero the equipment can operate at temperatures as low as minus 35 degrees
00:03:20 Celsius however the problem was easily solved by installing the protective test which supported the required temperature time of printing amounted to 24 hours to using new materials such as geopolymer concrete houses could be printed in both summer and winter in the printing process we used horizontal fiberglass reinforcement for the walls the quality of the printed wall surface allows to
00:03:54 perform final finishing immediately which significantly reduces the cost of finishing works the roof of the printed house in accordance with the architectural project is flat such a roof can effectively withstand high snow loads and durability requirements its cost is comparable with steep roofs which are common for our country a Peace Corps construction 3d printing
00:04:22 technology adapted for different methods of printed walls thermal insulation this project used loose dry insulating material on one part of the house and polyurethane filler composition on the other technology does not require fixtures and fills all voids in the space between the bearing wall and the outer concrete structure avoids the formation of cold bridges on the inside
00:04:50 the printed house is no different from a regular concrete house it is also comfortable and reliable the house interior includes a hall a bathroom a living room and a compact functional kitchen with the most modern appliances the house size is 38 square meters construction costs amounted to 10,000 $134 which corresponds to approximately $275 per square meter and this in view
00:05:23 of the shape complexity of the building prices include all works and materials for the construction of foundation roof exterior and interior finishing works installation of heat insulation of walls windows floors and ceilings a regular square house made using materials of an average price category would cost about two hundred twenty three dollars per square meter the use of APIs core
00:05:50 construction 3d printer allows to save up to 70% on erecting buildings boxes compared to traditional material and labor intensive construction methods the APIs core company and its partners are confident that this house was the first step which convinced the world that 3d technology on the market today is a reality 3d printers enters a global market and construction site worldwide
