Construction 3D Printing (c3Dp) or 3D Construction Printing (3DCP) refers to various technologies that use 3D printing as a core method to fabricate buildings or construction components. Alternative terms are also in use, such as Autonomous Robotic Construction System (ARCS) Large scale Additive Manufacturing (LSAM), or Freeform construction (FC), also to refer to sub-groups, such as ‘3D Concrete’, used to refer to concrete extrusion technologies.
There are a variety of 3D printing methods used at construction scale, these include the following main methods: extrusion (concrete/cement, wax, foam, polymers), powder bonding (polymer bond, reactive bond, sintering) and additive welding. 3D printing at a construction scale will have a wide variety of applications within the private, commercial, industrial and public sectors.
Potential advantages of these technologies include faster construction, lower labor costs, increased complexity and/or accuracy, greater integration of function and less waste produced. A number of different approaches have been demonstrated to date which include on-site and off-site fabrication of buildings and construction components, using industrial robots, gantry systems and tethered autonomous vehicles. Demonstrations of construction 3D printing technologies to date have included fabrication of housing, construction components (cladding and structural panels and columns), bridges and civil infrastructure, artificial reefs, follies and sculptures.
The technology has seen a significant increase in popularity in recent years with many new companies, including some backed up by prominent names from the construction industry and academia. This led to several important milestones, such as the first 3D printed building, the first 3D printed bridge the first 3D printed part in a public building, the first living 3D printed building in Europe and CIS, the first 3D printed building in Europe fully approved by the authorities (COBOD International), among many others.
Time management with technology
In India, survey shows that it takes almost 6 months to 1 year to build a house that is of a rough area of 2000-3000 SQ FT. Not only that, it takes numerous visits, attempts to find skilled labour, trial and errors and a lot of your toil and sweat to finish the dream of building a house!
It’s now time to get rid of all those tensions as 3D printed house enters India. It hardly takes 24-48 hours to get this small cosy house ready and it was all done apart from manual labour. Ozaz Global brings machine built construction to the country for the first time.
“Using 3D robotic technology and make in India concept we want to construct your dream house,” says Joshua Paul Voola, CEO, Ozaz Global.
A few key features of 3D Houses include cost effectiveness, durability, no manual labour hassle, time effectiveness and also saves water.
The technology reduces costs of anyone who wishes to build their house. The area where one saves a lot of money is hiring labour everyday, spending for raw materials and logistical expenses. This technology just requires one to programme the required design of the house one intends to build, say “a castle” or “a bunker”. The rest is done by the machine itself.
Also, this technology ensures that the entire structure that is built is crack free for 100 years or more. The composition used in the pre-mix is so solid that even the USA uses this technology to make Military Bunkers which needs to be rock solid. Using this technology will ensure that the houses once constructed are solid and crack free for a long time. This technology is eco-friendly as well. The general usage of water while curing of a house is very high when we talk about construction. But with this technology, the water is added to the premix and then on there is no water needed for curing. This saves a lot of water.
