What is 3D Printing Technology or Additive Manufacturing
3D Printing Technology or Additive Manufacturing is one of many methods of making three-dimensional objects. In this method, under the control of a computer, a substance piles layer by layer and makes the product. The items to manufacture can be of any shape and geometry. Before construction, we create a stereoscopic data source of the object. And under the control of computers, stereoscopic printers add layers according to their own. In fact, the stereoscopic printer is an industrial robot.

Global Scenario related to 3D Printing
Globally, the global 3D Printing market reached a level of about $ 7.01 billion in 2017. Talking about the use of 3D Printing is done at the industrial level, its market share was around 80 percent in 2019.
During the year 2018, 3D Printing Technology was most commonly used in hardware, followed by software, and least used in the services sector.
In the year 2018, North America ranked first with more than 37 percent of its market share due to the extensive use of 3D Printing Technology or Additive Manufacturing.
A team of American researchers has designed a ‘sponge’-like structure, elimination on the palm, through 3D Printing Technology that can be effective in reducing pollution. A team of researchers created a ‘sponge’ like plastic mold by mixing nanoparticles of the chemical agent titanium dioxide during the 3D Printing Process. Which has the potential to eliminate pollution from water, air, and agricultural sources.
History of 3D Printing or Additive Manufacturing
If you look at the history of manufacturing, then subtractive methods are first used. In the empire of the whole machining (in which exact shapes are prepared with high precision) subtractive methods are given more importance, in which filing and turning are predominated by milling and grinding. Additive Manufacturing applications have been ranked last in the entire manufacturing spectrum.
For example, rapid prototyping was one of the earliest additive variants. And its mission was that when prototypes of new parts and devices develop, then how can lead time and cost reduce. To do this earlier Subtractive toolroom methods (which were typically slow and expensive) were popular.
But when advancement started in technology, Additive Manufacturing methods start to using more in manufacturing. At a time where only subtractive methods were using, now profit is making by using Additive Manufacturing methods.
Benefits of 3D Printing
Low Cost – 3D Printing makes it possible to manufacture products at a lower cost than traditional methods.
Time Saving – Quality work can do in less time by 3D Printing. It is capable of increasing the efficiency of work.
Highly Efficient – Creating prototypes generated by 3D printing is possible with great ease and intensity.
Flexibility – Different types of materials can use for 3D Printing. This makes it easy to print a wide variety of prototypes and products.
Durable and High Quality – products do not absorb moisture, making them in use for a long time.
3D Printing Related Challenges
If we talk about the challenges related to 3D Printing, the variation in 3D printers will result in quality variation in the manufacture of products. Also, 3D Printers lack an ideal standard for product quality.
Plastic is the most common using product for making products under these printers. And it consumes electricity on a large scale. Which is not good for the environment in any way.
How does 3D Printing Work?
3D Printing begins. First of all, through the computer, we create a 3D Model in our system. In this, digital design is a CAD (Computer-Aided Design) file.
A 3D model creates from the ground up by 3D Modeling Software, which bases on the data generation of a 3D Scanner. At the same time, with the help of a 3D scanner, you can make a digital copy of an object.
3D Scanning Process & 3D Modeling Software
3D Scanning Process a process in which real-world objects or environment is analyzed about their shape and appearance to collect data. Digital 3D models then create with the help of these collect data.
3D Modeling in 3D Computer Graphics knows as the process by which a mathematical representation of the surface of an object is made or a 3D model creates through software. The product that is made by this is called 3D Model. And the people who work on these 3D Models are called 3D Artists or Designers.

Application of 3D Printing or Additive Manufacturing
Now let’s know about the different Applications of 3D Printing or Additive Manufacturing.
|Applications of 3D Printing or Additive Manufacturing|
Aerospace and Space engineers use 3D Printing to manufacture high-performance parts. The ability of 3D Printing is that these topology optimized structures which have a high strength-to-weight ratio can create such products. And the possibility that multiple components can be consolidated into a single part and which is very appealing can create such products.
This automotive industry has also gained a lot from 3D Printings. Because of this, they can do their customization easily and that too in a very short time.
For example, Volkswagen traditionally uses CNC machining to create custom jigs and fixtures. CNC typically has longer production times and higher costs. While these similar jigs and fixtures can easily prepare with the help of a 3D printer.
In the world of robotics & automation, custom one-off parts are always needed to develop new robotic mechanisms. 3D Printing evolving very soon in this industry to the main manufacturing technology. Because of their speed, great design freedom, and ease of customization is very good.
Its large range allows material options, with unique properties, to create unique structures. For example – “soft” robots.
In the development of new 3D Printing materials that provide high heat resistance and stiffness, which are aligned with their ability, so that they can quickly create custom parts at a very low cost. It promotes industrial tooling to use Additive Manufacturing in multiple applications.
The healthcare and prosthetics sector benefited greatly when they adopted 3D Printing. No need for manual labor to become hearing aids. They can be easily created immediately from a digital file. This allows them to be prepared at very low prices and in large quantities quickly.
With the help of 3D Printing, product designers can easily customize their products without any extra costs. They can easily create high-quality functional prototypes for new product concepts. At the same time, this also greatly accelerates the design cycle process.
3D Printing Technology has a lot of potential in educational environments. With its help, course subjects are getting a creative dimension. It equips students with practical real-life experience.
