3D printing also known as additive manufacturing is a technological process of making 3D solid objects from the digital files. Therefore, the creation of 3D printed objects is achieved through additive processes. In this process, objects are created by laying down the successive layers of the material until the entire object is created. Every layer can be viewed as sliced cross-section of the final object. It is now possible to have star wars models to 3d print from digital files. You can also design your own if you have skills.
How it works
Everything starts with the virtual design of a model you need to create. Virtual models are made of CAD software or using the 3D scanner. The latter means copying an existing object. Therefore, the scanner creates the 3D digital copy of the object. These scanners use various technologies to generate 3D models such as modulated light, structured, volumetric scanning, and many more. In future, digitalizing objects and items into 3D will be easy just like taking a picture.
Technologies and Processes
It is important to note that not all the 3D printers use the same technology. In fact, there are many ways to print objects. Moreover, all the printers currently on the market are additive. They differ in the manner layers are constructed to create the end product. Some methods use softening or melting to form the layers. The primary methods used are Fused deposition modeling and Selective laser sintering.
Applications of 3D printing include architectural, healthcare, rapid prototyping, and entertainment. This industry is expected to grow to 12.8 B by 2018. As it evolves, it is likely to transform nearly every sector and change the way people work, play, and live. For instance, in the medical industry, this technology keeps evolving at a rapid rate and specialists begin to utilize this type of printing in excellent ways. Nowadays, patients continue to receive improved health care thanks to 3D printed prosthetics and implants.
This is also known as domestic 3D printing. It is mainly for the enthusiasts and hobbyists. It has grown over the years. Because of rapid growth in this sector, there are now new printers, which are getting cheaper as days goes by.
It is told that additive manufacturing advocates for the technological development, which will change nature of the business. This is because final product users can do a lot of manufacturing instead of engaging in buying products.
