Analyzing How 3D Printing Transforms Modern Construction
In the field of construction, 3D printing has emerged as one of the new technologies that replaces several manual works with the help of a machine that creates and assembles structures. This technology is a more cost-effective, convenient, and environmentally friendly way to frame modern buildings. This type of construction technology is widely adopted by companies which sequentially layer materials through computer-controlled processes to create a 3D shape.
3D printers are beneficial for creating new structures on-site or manufacturing components off-site for later assembly. Moreover, these printers get the details of dimensions from a software program and build the structure on a platform using raw materials such as cement, plastic, or liquid metals.
Reasons behind the popularity of 3D printing
The rise of this modern technology has come up with a wide range of solutions to overcome the hurdles of traditional construction. With the help of 3D printers, many leading construction companies have reduced waste generation at the construction sites. These modern printers utilize the required number of materials needed to build a particular project, which generates almost zero waste.
On the other hand, this modern technology offers significant environmental benefit by using recycled materials in construction. Advanced 3D printers create lattice patterns with reusable materials such as concrete and plastics to design a robust structure.
Moreover, the most significant benefit of adopting 3D printing into construction is to quickly deliver projects without any delay. However, there are many challenges such as bad weather, shortage of labor, and electricity issues in remote areas, which a construction project faces during its completion. However, with this automation, many leaders in the domain are able to deliver projects before time.
This modern technology provides custom solutions that allow architects to design buildings by utilizing new architecture software. 3D printers are helpful in constructing buildings with unusual shapes such as oval, pentagonal, and prism. In addition, they offer a cost-effective alternative to builders by saving money on labor and time for construction projects.
Diverse methods of 3D printing in construction
The 3D printing construction industry has observed prominent growth due to increase in deployment of different printing methods in construction. According to Allied Market Research, the sector is anticipated to manifest a CAGR of 105.8% from 2024 to 2032. In the past few years, extrusion has been a popular printing technique that is widely used due to its versatility across various environments. This method builds objects layer by layer by depositing material through one or more nozzles mounted on a robotic arm, gantry system, or crane. This is why it has become ideal for modeling, prototyping, and production.
Moreover, powder bonding has emerged as another notable method of 3D printing technology that uses powdered raw material as its main component. Mostly, there are two types of powder bonding techniques, one is powder bed jetting and another is binder jetting. Powder jetting involves using a laser to melt dust particles layer by layer, forming the desired object, while a coating sheet continuously adds material for each new layer. On the other hand, binder jetting utilizes a print head to deposit a liquid adhesive onto the powder bed, binding the particles together layer by layer to create the desired object.
14Trees secures funding to expand low-carbon 3D printing in construction
In October 2024, Amazon’s Climate Pledge Fund, along with Holcim and British International Investment (BII), invested in 14Trees during its Series A-1 funding round. 14Trees, a company that uses 3D printing for construction, is expected to use this investment to promote eco-friendly building methods in Europe and the U.S., focusing on low-carbon infrastructure and innovative construction techniques. The investment allows 14Trees to deploy its 3D printing technology with Amazon and Holcim, advancing low-carbon data centers, large-scale buildings, and utilities to reduce environmental impact through sustainable construction materials and software.
