3D Printed Building- Interesting Facts to Know
We all remember the time, not so long ago when we had to hire workers to make a building and work on the project for days or months. The process costs so much and with each unexpected problem of the workers came an unexpected delay. The delayed construction and high costs created a need for the technologists to come up with a better idea. Thus, the 3d models for printing came into existence. 3d building printing gave rise to new horizons in the field of construction and manufacturing.
3d printed buildings are built by using the technology of 3d printing as a means to construct houses and buildings in the most efficient and cost-effective method. This method has vastly been adopted by the Chinese and has also gained its worth in Europe. This makes sense because people are tired of bearing high expenditures, lengthy construction timings, and never-ending design processes. Today, 3d printing has enabled you to forget all these worries about people wearing yellow helmets and use robotic techniques for mechanical piping of concrete. So, a 3d printed building will save you from the trouble by giving you the perfect 3d model for printing.
Interesting facts to know about 3D printed houses:
- Resolve the future homelessness
We see homelessness as one of the significant issues of humanity at present. According to estimates, homelessness can exceed up to 1.6 billion people living in the improper shelter by 2025. Building a house or building from scratch can cost people a lot. A building offering flats or hostels can save the problem by efficient working on buildings that save your cost. By replacing the traditional and lengthy methods of using bricks and mortar with automated robotic piping of concrete, one can save time and money while still reducing the problem of homelessness in society.
- No need for bricks
As hard as it is to imagine, houses can today be made without using bricks and mortar. Bricks and mortar took more time and effort for the builders to work with, and it used to leave us for waiting the time for its completion. However, by using 3d printing, robots can pipe in the concrete step by step and even the building at the same time. This saves you the costs of buying all the material for construction and also protects from wasted time.
- Robots are your builders
There was once a time where it was hard for us to believe that humans can create robots one day. Today, we are at a stage where robots have become so efficient that they have become the new builders. The robots are very efficient, and they don’t need breaks like human workers. This saves more time, and work is also better than humans. The human errors are also removed to the greatest extent possible, and all humans need to do is to command the machine, and it will work for you.
- Save the cost and time
Constructing a building is a full-time job. A building project needs to be carefully catered with and must be monitored to save it from defects and additional costs. By using 3d printing in the construction of buildings, you can save the value of the construction process by saving more time. It will also cut down the labour cost because all 3d printing needs is an initial investment, and the rest will be catered in the least possible time. Dubai today has been working on the 3d printed buildings and have been one of the most efficient working hubs for 3d printing worldwide. Thus, more and more people are adopting this new technology because it reduces costs by optimizing raw materials and useful results.
Thus, 3d printed buildings have become a new trend around the globe. People are willing to rely on robotic technology rather than humans with risky results. Robots can be left alone at the workplace without any check and balance and will work for creating a sustainable working environment.
The only problems with 3d printed buildings are that it needs initial capital investment and also any defect in the robotic machinery can cost a lot to correct as well. Another problem with 3d printed buildings is the fact that it also reduces the job opportunities for builders and manufacturers. However, 3d printed structures are an effective way to meet the construction requirements in the minimum of time.
Additive Composite and Add:North develop unique neutron-absorbing filament

A brand-new development was made with a joint effort of Additive Composite and Add:North, both Sweden-based companies. The Addbor N25 filament is expected to designate the beginning of a new era. The new composite has radiation shielding capabilities, which means it can be used for 3D-printing of radiation protection means. It is compounded with co-polyamide matrix as a base polymer filled with boron carbide. The filament composition provides for a higher degree of chemical and heat protection levels.
The material is expected to be applied in nuclear industry, research labs and other facilities that suggest radiation exposure. Its main anticipated area of implementation is production of radiation-shielding equipment that’s free from toxic heavy metals, such as cadmium.

“Additive manufacturing is changing how many products are being designed and produced. We believe that Addbor N25 contributes to this development and helps both industry and large research facilities to replace toxic materials that could eventually contaminate the environment,” says Adam Engberg, CEO of Additive Composite
Boron carbide accounts for 25% of the compound’s total weight, and the filament density is expected to be 1.33 g/cm3. The recommended settings for stable printing are the following: nozzle temperature of 250-270ºС (480-520ºF) and bed temperature ranging from 60 to 100ºС (140-210ºF). 3D-printing is recommended to be carried out using hard ruby nozzles developed by Olsson Ruby or sapphire nozzles produced by SAPPHIRUS due to filament’s abrasivity and hardness. The use of above-mentioned nozzles will ensure that printing quality stays high and prevent nozzle sprayers from wearing out too quickly. The manufacturer suggests using nozzles with the diameter of at least 0.4 mm (0.016in). The filament is promised to feature excellent layer bonding, moderate flexibility, low shrinkage and good chemical resistance. Furthermore, the tensile strength at break is 58 MPa and flexural modulus is 1425-3650 MPa. Addbor N25 can easily handle continuous utilization at 100-110ºС (210-230ºF).
The cost of a 1.6 lb (750g) filament spool is 9 500 SEK (980 USD). Taking a different perspective, that’s a medium cost for a used car. The available filament diameters are 0.07 inches (1.75 mm) and 0.1 inches (2.85 mm). The product page is available on Additive Composites’ official website.
