When considering 3D printing, individuals imagine creating small plastic objects. However, it has a lot of power and is used to create many products and systems.For example: furniture, movie props, medicinal equipment, even and space parts. But now with the advent of printable building materials, 3D printing has gained much popularity as it replaces physical labor with machines and tools that build and assemble structures, creating a more cost-effective, convenient and environmentally friendly way to develop and create new structures.
This blog by Stonedge construction provides an explanation of 3D printing technology in construction, how it works, its uses and benefits, and more.

What is 3D printing technology in construction ?
3D printing, an innovative process for creating three-dimensional objects from computer-aided design (CAD) models. It works with a simple concept called step-by-step construction.3D printing adds materials in successive layers to build an object.The process starts with a digital 3D model designed using specialized CAD software or obtained through 3D scanning technology. 3D printers are helpful for both on-site manufacturing and off-site production of components that can be assembled later. These layers guide the 3D printer as it deposits materials, typically plastic, concrete, metal, or other composite materials, following exact instructions from the digital design.The printer takes dimensions from a software program and builds the structure on a platform using materials such as cement, plastic or liquid metal.
Large 3D printers are often used for printing buildings by extruding controlled building materials based on pre-programmed designs. The printer deposits material layer by layer to build a digital model or design.

Uses of 3D printing in construction :
3D printing can be used in several construction scenarios. Some of these are –
Creating architectural models :
Modeling is when construction companies or architects scale proposed projects to a size that you can view in a smaller space. This allows clients to inspect the design, layout and other elements of a structure. With traditional construction, people typically design structures through software and then build models manually. 3D printing can quickly build models once you’ve created the structure in your computer program and the printer has your materials, allowing you to create more architectural models.

.
Buildings :
Increasingly, 3D printers are producing entire buildings and other structures, including temporary shelters, permanent homes and offices, and bridges. This offers a less costly and quicker construction process.
.
.
Creating prototypes :
Prototypes are preliminary models of structures that give people an example of what something could look like. For example, if a company wants to build a new office, a 3D printer could create a prototype for the office much easier than a construction company could level the ground, hire labor and prepare full construction sites. Although there’s still a cost, 3D printing provides clients with the ability to create these prototypes much quicker and at a lower price than constructing full prototypes through traditional building methods.

.
Formwork Solutions :
Formwork provides a mold into which construction materials, like concrete, can be poured. The material is held in place until it has solidified and is strong enough to support itself. Formwork solutions are particularly useful for 3D printing since the materials rarely need to be long-lasting or highly durable.

Advantages of 3D printing in construction:
Speed and Efficiency :
Utilizing 3D printing technology in the construction industry can enhance the speed and efficiency of construction operations.This technology reduces project completion timelines and enables quick and efficient construction(production).
Fewer Building Errors :
A 3D construction printer reduces the frequency of construction faults. Human mistakes are more prone to occur while traditional houses are being built. However, when a house is 3D printed, the 3D printer creates the entire building structure with zero errors, but only as long as the blueprints entered into the 3D printer are correct.
Enhanced safety:
Automating certain construction processes through 3D printing reduces on-site labour requirements, potentially minimising worker exposure to hazardous conditions.
Design flexibility and customization: 3D printing allows architects and builders to explore intricate designs and tailored structures that were once challenging or impossible to create.
Structural strength and durability:
Innovative construction-grade materials used in 3D printing can be optimised for strength, durability, and resilience, resulting in robust structures built to. withstand diverse environmental conditions
Remote construction:
The ability to transport 3D printers to remote locations facilitates construction in challenging or disaster-stricken areas, providing quick and efficient shelter solutions.

Types Of 3D Printing in construction:
.
.
Gantry System :
A gantry system is a frame structure that supports the printer head along the X/Y axis in 3D printing. It comprises beams and slide rails that support and guide the printhead/extruder as it moves and prints.They are common among construction groups that 3D print large-scale structures and buildings and can print much larger objects than other 3D printers, making them perfect for construction projects.
.
.
Sand layers :
In this method, the 3D printer releases layers of sand to build structures. Once the layers reach the desired level of thickness, the machine releases droplets that harden and bind the sand. You can use this method for smaller structures or materials in construction.
.
.
Robotic arm :
Automatically controlled printer that allows freedom of movement and flexibility to schedule multiple tasks. The arm is capable of printing from multiple angles, allowing the realization of complex geometries and curves, and printing in larger sizes compared to other 3D printing methods.
.
.
Powder Binding:
Powder binding in 3D construction uses powdered raw material and includes two methods: powder bed jetting and binder jetting. Powder bed jetting melts dust particles with a laser layer by layer, with a coating sheet adding more material for each new layer. Binder jetting uses a print head to deposit a liquid adhesive on the powder bed, binding the particles to form each layer. This method allows for higher accuracy and more complex prints.
