3D Building Approaches That Are Currently In Use Nowadays

Table of Contents

3D Building approaches provide us with a great deal of affection, care, protection, and personal space. Everything we do in life requires buildings, including our homes, offices, schools, colleges, banquet halls, universities, and so on.

A dreadful pandemic, many storms, and tremendous rainfall have just struck the planet; in this situation, buildings are no less than heaven. We require construction on a regular basis, so it is critical to make the process easier, more cost-effective, durable, and modern.

The 3D building construction strategy is a relatively new addition to the architecture industry that has been praised for its ability to provide visible results thanks to the computerized technology and precision it employs. This is a significant step forward in the modernization of the construction industry, and we need to understand how it works.

Difference Between 3D Building approaches And 2D Construction?

3D building approach in construction is a computer-controlled technology that fabricates construction components and buildings using 3D printing techniques. 3D printing, also known as Additive Manufacturing, is a method of creating three-dimensional structures by using computer algorithms and automated machinery to build sequential layers of construction materials.

When viewed from afar, 3D printed buildings appear to be traditional structures; however, closer inspection reveals that the structure is made up of layers of materials pasted on top of each other with the assistance of machines, rather than bricks.

A layperson might mistake a 3D printer for a different type of paper printer, which is far from the case. Robotic arms are attached to 3D printers, which follow the command and deposit layers of constructive material on the surface according to the design.

3D printers feature high-tech software programs that guide them about the proportions of a building. CAD and BIM are two well-known programs that assist 3D printers in contributing.

On-site and off-site 3D builds are also possible. To generate intricate three-dimensional designs, these printers frequently use liquid construction materials such as cement, molten metals, and liquid plastic.

Some of the top 3D construction examples from around the world:

  • China’s 3D Printed Public Restroom
  • DFAB HOUSE is located in Switzerland.
  • Italy’s GAIA
  • Madrid Pedestrian Bridge
  • Netherlands Bicycle Bridge
  • Russia’s APIS COR Residential Home
  • The DUBAI Municipality Office Building is located in Dubai.

What Are The Most Effective 3D Building approaches?

Although different construction businesses utilize a variety of 3D building approach to get the most out of 3D printing, the most common ones are here.

Extrusion Approach Using Robots

We love robots, whether they’re replacing human waiters in restaurants or acting as your personal assistant. However, until recently, architecture was a field in which fewer experiments were conducted. The precision of robotics is now combined with high-tech software programs to generate remarkable building structures, thanks to the introduction of 3D printing.

The method “Robotic Arm Extrusion,” involves pairing a six-axis robotic arm with a 3D printer, with the robotic arm responding to the printer’s commands. However, before the robotic arm begins depositing building materials, a structure is built on the construction platform to serve as a mold for the robotic arm to follow.

The 3D printer is pre-programmed with the dimensions and shapes to be created, and then the machine is turned on. The printer issues commands and the robotic arm begins depositing concrete mixture into the molds in order to construct the edifice.

The arm, which may move in six directions, adjusts and extrudes the concrete for a beautiful and smooth finish. Furthermore, robotic arms and trowels are there to flatten the concrete right after its deposition.

The contour crafting method is a term that helps to describe the robotic extrusion methodology. One issue was that this approach cannot help in traditional cementing because it takes too long to dry. Designers came up with a solution that involved employing quick-drying cement, which produces a better surface and is appropriate for robotic arm extrusion.

Approach to Powder Bonding

Despite the fact that the Robotics Arm procedure is one of the best for 3D printing techniques, several approaches distinguish this technology. Powder bonding is a 3D construction method that involves depositing powder materials such as sand in particular shapes and thicknesses, then pouring binders over them to harden the powder substance. The bed fusion strategy and the binder jetting approach are two methods for moving powder printing forward.

Fusion of Powder Beds

powder 3D printer is helpful in this technology. It uses a laser to melt and combine powder particles into the required mold. The machine continues to deposit layers of this connected powder material until it achieves the desired three-dimensional structure. After the completion of each layer, an automatic recoating blade continuously feeds additional powder material to the printer.

The powder bed fusion laser’s modest size has shown to be particularly effective in producing a detailed structure. The bed fusion approach is ideal for projects that require a high level of precision and complexity.

3D metal printing

Binder Jetting approach

If you compare this approach to the bed fusion one, this is really straightforward. A print head is more useful than a laser to pour a binder liquid on top of the powder print bed. The powder print bed is just an assembly of construction materials in powder form, arranged in the appropriate shape on top of which this binding agent is present. Powder printing can print structures out of a variety of materials, including sand, silica, and metals.

Approach to Wire Arc Additive Welding

MX3D, a Dutch business, created Wire Arc Additive Manufacturing, or WAAM, a unique 3D printing technology. The WAAM technology is a version of Direct Energy Deposition that melts metal wires for fabrication using an arc welding approach.

Using any material in wire form, this technology may quickly construct metal structures. An electric arc is helpful as a heat source to melt the metal wires. These subsequently deposit as beads on the building plate by a robotic arm. This technique repeats until many layers of metal beads cover the plate. Finally, you will have the complete product in your hands.

WAAM technology is particularly useful for developing large-scale metal parts, buildings, or construction components. It is because the robotic arm has far greater room and mobility. WAAM is also a cost-effective method because the welding wires used in the technology are less expensive than those used in powder bonding machines.


People nowadays demand unusual, one-of-a-kind, and cost-effective products. The same concept is applicable when it comes to their structures! 3D building approaches is a term that refers to the most significant advancement in the field of architecture. It saves money and time, improves the structure’s durability, and is environmentally friendly. Moreover, it has a modern aesthetic, all in one package.

Despite its advantages, 3D construction has only achieved popularity and confidence among a small number of clients worldwide. However, the graph is expanding. Besides, sooner or later, this technology will govern everyone’s hearts and turn the building industry on its head. Building Construction will be the future after a few more years of recognition and 3D printing.
