Using 3D printing online for construction, many wonderful and innovative projects have been developed. Several architectural and construction firms are adopting 3D printers to design and construct buildings. But what are these structures made up of? What is the material being used to 3D print buildings?
This article will answer such questions in detail.
WHAT ARE THE MATERIALS BEING USED FOR 3D PRINTING IN CONSTRUCTION INDUSTRY?
Additive manufacturing is all about the material. Depending on its application, the type of material used for online 3D printing in india changes. For structural applications, basic material like cement, sand and other additives is required. However, while 3D printing, some extra variants are also used.
The exact recipe of the mix depends on the purpose as well as the 3D printer. To understand this more clearly, we will look at some real-life examples of construction with online 3D printing Bangalore.
- BUILDING ON DEMAND IN COPENHAGEN (COBOD)
COBOD is a European start-up company that uses 3D printing for construction. In 2017, this company was responsible for 3D printing the first building in Europe: The Building On Demand (BOD).
All the elements in BOD are completely curved except the straight doors and the windows. Even the foundation of this building was 3D printed. COBOD used a construction printer capable of working in three dimensions so that it can access any position within the envelope. The printer was also used as an on-site ‘crane’ to place certain elements into the building.
In collaboration with FORCE technology, COBOD developed a strong and sustainable concrete mix using recycled material. They used a mixing pump that automatically filled the dry material mix from the mixer. After this, water was added to the mix to keep the pump filled.
Material used: Concrete mix consisting of cement, sand and other additives.
- WASP: GAIA
WASP is an Italian start-up company that uses local materials to construct 3D printed sustainable houses at an affordable price. They used their vision to 3D print an eco-sustainable house, the Gaia. It is the first 3D printed mud house made from naturally available materials.
The 3D printing of this earthen structure used a material mix consisting of soil, lime and rice fibres. The mix was made homogeneous and workable by mixing it thoroughly in a wet pan mill. The extrusion was done by a Crane WASP 3D printer.
Finishing was done by shaving clay lamina on a monolithic wall. It was then smoothed and oiled with linseed oils.
Material used: Natural material mix consisting of 25% soil, 40% straw chopped rice, 25% rice husk, and 10% hydraulic lime.
- TVASTA: ROOM MODULE
Tvasta is an Indian start-up company that aims to provide quality construction to make affordable and sanitary homes available to people in the remote parts of the country.
It is the first company to build a concrete 3D printed structure in India. Tvasta, in collaboration with IIT Madras, created a specialty concrete that was affordable as well as sustainable. It is like the basic Portland cement but with a lower water-cement ratio. Amorphous metal fibres or plastic fibres are used along with the cement, based on the application.
The structure made by them has a 12 mm rebar on all four corners for secure attachment. It is also present in the hollow sections of the structure to provide tensile strength. The structure was specifically designed and 3D printed with hollow sections so that while wiring and plumbing, the walls are not damaged.
Material used: Concrete mix based on ordinary Portland cement, but with lower water-cement ratio and consisting of cement, sand, and other additives.
- APIS COR: RESIDENTIAL HOME
Apis Cor is an American start-up company based in San Francisco. They are dedicated to developing mobile 3D construction printers capable of printing structural components like self-supporting walls and partitions. They were successful in 3D printing a house in a suburb in Moscow in just 24 hours.
They have developed their own material mix for 3D printing. This concrete is extrudable and consists of sand, cement, geopolymers and fibres. The final mix is prepared by mixing all the materials in a big hopper. The extruder receives this mix through a pump system and then deposits it.
The structural components are 3D printed on-site with a printer that has an independent robotic arm. A small gap was left between the interior and exterior of the walls of the house.
Fibreglass reinforcements were placed in this space. In addition to this, a Polyurethane-based mixture was sprayed in the gaps to insulate them. After 3D printing the walls, a crane was used to remove the printer for installing windows, appliances and a roof.
Material Used: Concrete mix made up of cement, sand, geopolymer, sand and other additives.
- WINSUN: WAVE BUILDING
Winsun is a Chinese start-up company that started as a supplier of building materials but soon developed their own 3D printer. Their 3D printer is capable of constructing large scale buildings at a high speed.
They took the 3D printing construction market by storm when they printed ten houses within 24 hours! The components are printed off-site in a factory and then transported and assembled on-site.
Along with the printer, they have developed their own material mix which is environmentally friendly and produces zero waste.
Material used: Concrete mix made up of cement, sand, fibre and other additives.

3D Printing service Benefits in Architecture
Architecture is a highly competitive area and, with any project launched, architects face tough competition when clients have a wide variety of choices.
Architectural companies must aim for success and creativity to stand out and remain ahead of the competition. They should be able to win more projects in the future.
Exploring 3D Printing online services in India can give architectural companies an improved chance of survival, as it provides multiple advantages.
Display Complicated Designs in Better Specifics
A 3D printer proves to be an essential medium for printing and viewing intricate elements, such as the façade or the intricately textured roof. These complicated and detailed features, which would usually be a burden or difficult to design by hand correctly, can be easily accomplished with 3D printing online.
This will improve visual perception and encourage clients to understand how the features would appear in real life. It could also demonstrate how the shadows and sunshine would appear during the day to bring the model to life.
Experiment on a variety of materials and shades
A wide range of 3D printer filaments allows architects to express the feel of their design adequately. It decreases the work of painting or choosing an acceptable colored material to be used in various model areas.
Using explicit, shiny or white materials will add a touch of beauty. It enhances the model’s overall aesthetics and highlights how the building will look in contrast to its surroundings.
Significantly slash Manual Labor and save 100 hours of overtime.
Making a construction design by hand is a long and monotonous process that demands persistence to produce quality performance. Depending on the size and detail, it can take several days to manually create a conceptual model made of cardboard, foam or wood.
Manually constructing a final model involves a longer timetable that can take a few weeks to complete. This is a significant expenditure in time for a single model, and the use of a 3D printer would quickly slash the timeframe by a large amount.
The technology bypasses all the measurement, cutting, bonding and other human work needed to construct a whole model, allowing Architects more time to concentrate on their design.
Build several copies
Many versions of the final model can be conveniently generated, and the 3D print image can be stored forever for potential reference purposes. The ability to quickly make many copies is incredibly unusual, given the conventional methods of model building.
This allows the architect to provide their customers and partners with a scale model replica of the project.
Easily Verify Design concepts
3D Printing service in India enables developers to quickly validate several design concepts and make prototypes in the early stages of projects. This dramatically improves efficiency and helps programmers detect possible defects that may be more difficult to find on a Revit programming model.
Architects can print 3D low-cost architectural research models that can be used to determine the flow of space, the general layout, the volume and the way natural light flows in the building.
Making adjustments to the operating model’s size helps to assess the relationship between the house and its immediate surroundings (which can also be printed in 3D). And, on a broader basis, how it blends within the neighborhood.
Zero waste construction
The building industry generates almost a third of a country’s waste. Although a decent portion of this comes from demolition, construction sites tend to be inefficient, too. It is normal to order more supplies than is required, which is costly and inefficient.
By comparison, online 3D Printing India can reduce waste to almost zero. A 3D printer uses only the material used to print the structure – no more or less. This could result in massive savings.
Combine emerging technology and traditional approaches
Although 3D Printing service in India can fully replace traditional modelling approaches, technology can also be improved. Few designers do not choose to completely automate their workflow model, as designing a model from scratch is a practice for architects.
The field of architecture is thought to be an art, and leaving any model building techniques to be performed manually will remain true to its origins. However, the exact development of complex geometrical features may not be feasible by hand.
3D printing these pieces and adding them to the handmade model produces a hybrid and can convey the concept in ways that never before.
Beyond the hype
Although online 3D Printing India is an enticing idea, it is important to pierce through some speculations. Sceptics pointed out that there are few drawbacks to the technology:
R&D expenses
Many construction companies work on relatively modest profit margins. The expenditure needed for the widespread use of 3D printing designs would be immense.
Difficulties in integration with other elements
3D printers are very good at pursuing creative and fascinating designs. However, sometimes you need a structure that combines several media or has various features that do not integrate well with 3D Printing service in India. It will be challenging to integrate a 3D model practically into such a design process.
CONCLUSION
Although the material is a crucial factor in determining the structure’s quality, the ability of architects and strength of designs and machines is also important. 3D Printing service in India has provided a faster, cheaper, and more sustainable alternative of construction to the world.
Continuous research is being carried out to develop better materials for use in 3D printing of structures. The most common material in use, for now, is a concrete mix made out of cement, sand and other additives. However, companies like WASP have succeeded in developing earth-based materials as well. The options will surely continue to grow.
