3D printing is a rapidly developing technology, which emerges with its set of inherent benefits. During the 3D printing process three dimensional solid items are made from a digital file. There are many accumulative processes involved in the making of a 3D printed object. During this process, an article is created by arranging sequential layers of materials to make the object.
3D printing is contrary to subtractive manufacturing which involves cutting a piece of plastic or metal with a milling machine. With the help of this revolutionary technology, we can produce complex shapes using less material than old manufacturing procedures.
What is the Function of 3D Printing?
First, a 3D model is created on the computer. This digital design is in the form of a CAD file. A 3D model can be created with a 3D scanner or 3D modelling software. You can easily create a digital copy of any object with a help of 3D scanner.
3D Modelling Software
There are many types of 3D modeling software. 3D modeling software is usually made according to the functions of different industries. As a result, much software is created appropriate to specific functions. There are also many software applications that created for different industries like transportation, aerospace, furniture design or fabric and fashion.
The Process of Slicing
A 3D model must be created to make a 3D print of an object. It involves slicing in which a 3D model is divided into hundreds or thousands of flat sheets. For this purpose, a slicing software is used to attain the required results. A 3D printer scans it after the slicing of the 3D model. This can be done through SD, USB or Wi-Fi. After the uploading of the file on a 3D printer, the object starts to divide into many 3D layers.
The Emerging 3D Printing Industry
3D printing technology is meant to convert nearly all-important industries with its amazing functions and applications. It is changing the mode of our living, work, and play in the coming days. It encompasses many forms of technologies and materials. It is not limited to a simple desktop FDM printer according to general view. This useful technology can be divided into plastic, metal, fabrics, automotive, and many other industries. That is why it should be seen as a group of various industries with numerous different applications.
Applications and Examples of 3D Printing
Applications include architectural scale models and mesquites, fast prototyping and manufacturing, automotive, aeronautics, aerospace, product designs, bioprinting, nutrition, movie props and 3D printed prosthetics. Other examples of this emerging technology include replicating ancient artifacts in archaeology, restructuring fossils in Palaeontology, reforming bones and body parts in forensic pathology etc.
