3D Printing: Reddy Kancharla Explains the Benefits

3D printing in construction is relatively new. This technology replaces some manual work in construction with a machine that creates and assembles structures. It can be a more cost-effective and convenient way to construct new buildings. According to Reddy Kancharla, learning the benefits of 3D printing in construction can help you decide if the technology can streamline your workflows and improve client satisfaction.

3D printing sequentially layers materials via computer-controlled processes to create three-dimensional objects. 3D printers can create new structures on-site or manufacture components off-site for assembly. The printer receives dimensions from a software program and uses plastic, cement, or liquid metals to build the structure on a platform. Here are some examples of 3D printing in construction.

Robotic arm extruders

The robotic arm extruder method involves a crane-like structure that moves back and forth, creating layers and releasing materials. Construction companies can install rails around building spaces so the arm can change position and height as needed. This method can also be used for smaller 3D printing activities. Depending on your materials, projects using this method may require additional labor. For example, you can mix concrete and pour it into the printer while building to prevent it from hardening prematurely.

Sand layers

A 3D printer can also be used to release layers of sand to build structures, adds Reddy Kancharla. Once the layers reach the desired level of thickness, the machine releases droplets that bind and harden the sand. You can use this method for smaller materials or structures in construction.

Combination with other technology

You can combine 3D printing technology with other technology, such as welding. Reddy Kancharla explains that the robotic arm or other printing technology can layer materials. Welding can then solidify the materials as they are being printed. This method can create structures such as small bridges that do not have a foundation.
