What is 3D Printing and How can it help in Construction

3D printing or also known as additive manufacturing is a process where three-dimensional objects are created from just a digital file. The creation of the 3D printed object is done by using an additive process. In this process, the object is created successive layers of materials until the object in mind is created. Each of the layers is seen and then thinly sliced horizontal of the eventual object. 3D printing is actually the opposite of what is called subtractive manufacturing which is hollowing or cutting out a piece of plastic or metal with a milling machine. 3D printing enables you to create different complex shapes using traditional manufacturing methods and less material.

The construction industry

In the construction industry, 3d printing can create different construction components that can print actual buildings. The construction is suited to 3D printing as most of the information that is needed to create an item which will exist as a result of the process. The construction industry is experienced in computer-aided manufacturing. Most air compressors used within these industries have made use of the technology of 3D printing that helps them in producing those spare parts that are customized for the industry. The recent technology of BIM building information modelling can facilitate the greater use of 3D printing. 3d printing can allow for more accurate and faster construction of the complete items and the ability to lower the about costs which will, in turn, produce less waste. It can also enable the construction to be done in more dangerous and harsh environments but is not yet suitable for use in space.


Construction projects can split their costs into different categories of materials, labour and finance. 3D printing can erase the significant amounts of money that bring construction projects to market by shorted project times and a reduction in wasted resources.

The technology can replace the labour-intensive trades including plumbers, builders and electricians. There are over one million that are employed within the construction industry and that is just in Australia when it comes to using 3D printers you are going to create such prototypes of the early products and be able to complete small manufacturing orders that will impact the number of workers needed which can be of concern. Smaller businesses that have a 3D printer can create their own prototypes so they can then bypass the manufacturing process which gives them more power for the start-ups.

However, there are still indications that 3D printers will be able to create more jobs through a technique known as contour crafting which has been developed to help builders create bigger projects with the 3D printer. 3D printers are more accessible, and they will move to the home soon where consumers are able to create their own products starting from air compressors used in a small garage to the air ventilation technology needed in the kitchen. The blueprints for these products will become more valuable.

There are six different types of materials that are used in 3D printing from metals, concrete, plastic, paper, ceramics and edibles. The materials are produced in wire feedstock which is also known as 3D printer filament, liquid resin or powder form. The different 3D printing techniques that can all be used in construction used these materials. There are so many ways that 3D printing is changing the construction world and with technology growing each and every year it is only going to get better and better over time.
