Additive manufacturing technology uses additive layer technology to create complex designs with ceramic-based material. Additive printing has its application in the aerospace industry, automotive industry, heavy machinery, medical parts, robotics, sports, and others.
Many fields wield 3D printing or additive manufacturing because additive layer technology can build complex parts with precision. From local schools to large-scale industries, the applications and benefits of additive manufacturing are spontaneously growing ever since the technology came into being.
Like every technological advancement, additive technology has its own set of limitations. The two most basic impediments of additive manufacturing are dimensional precision and exterior finish. But by using the correct material and process, such as standard resin and material jetting technique, one can obtain dimensional exactness.
Advancements in Additive Technology
The oldest piece of equipment related to additive manufacturing is from 1980. From the 1980s to 2022, many new features and advanced technologies have reached the market.
Since the 2013 boost that additive technology received, many companies are known for providing effective additive machines. These companies include 3D Systems, MASSIVit 3D, FormLabs, Stratasys, EOS, etc.
With the increase in demand, the production and technology used in additive technology are rapidly enhancing. Since its arrival, additive manufacturing has revolutionized the manufacturing market, and with the technological advancements that its producers have to offer, it can change the market forever.
In China, A Shanghai-based company 3D printed a five-story building with recycled materials to showcase the future that additive manufacturing has to offer us. Here are a few advancements that one can expect from the additive industry in the coming years
One of the biggest hurdles manufacturers has while using additive manufacturing machines is the time they consume. The manufacturing of a single design can take weeks. Some companies have reduced this time frame from weeks to days.
One can reduce the time for printing by using an optimized process that uses lesser steps and easy finishing. These fast technologies can save time, money, and resources. In the past few years, the process of 3D printing has caught speed, but in specific techniques or machines only.
In the coming time, the prediction is that most firms will be able to produce fast results.
Use of Diverse Materials
The most common materials used in 3D printing are plastic, metal, nylon, material powders, and carbon fiber. These materials are valuable in many fields, but they are impractical for many other products and domains that may benefit from additive manufacturing.
Many researchers have been evaluating the applications of multi-material printer technology. Although the technology is in its initial phase, it promises a better future for additive manufacturing. Bio-materials are also an option to explore for the manufacturing markets as machines will soon be compatible with bio-materials.
Bio-material printing will reduce the ecological effects of the industry, and the multi-material options will allow the manufacturers to explore advanced design and applications.
Hybrid Machining Systems
As mentioned earlier, the additive does have its limitations. To overcome these limitations, some engineers have come up with hybrid solutions. These solutions involve traditional as well as additive methods to build the design.
This type of process will enhance the accuracy of the final products. The traditional methods use subtractive technology, while the additive procedure uses layer additive technology. Manufacturers can form the product through layer additive technology and then use the subtractive technology to achieve accuracy.
Various companies are already using this methodology to enhance their product quality and precision. Hybrid machining has a high scope for the future of manufacturing.
4D Printing Technology
3D printing allows the manufacturers to print a design in three dimensions with the help of a solid material. 4D printing is almost the same as 3D printing, but the fourth dimension is time.
The addition of a fourth dimension means that the design can change its shape, property, or functionality with time.
This feature allows the product to self-assemble or repair once broken. Through sleek designs in 4D printing, the manufacturers can also create multi-functional parts and products. 4D printing requires a sophisticated layout and suitable material to make a product. It may also demand an external stimulus to activate the time-related transformation.
Many other advancements such as sophisticated software to identify the best process for designing an object, advanced monitoring systems to heighten the accuracy of the machine, and micro-manufacturing techniques to hoist the complexity of designs promise the bright future of additive manufacturing.
