Advanced manufacturing technology is a critical element of the Industry 4.0, which defines the upcoming generation of smart industries. The use of 3D printing or Additive Manufacturing will expand in the coming years, as a means of producing products that have greater customization which reduces costs.
3D printing or additive manufacturing is a process in which material is joined to create a three dimensional object. Initially, 3D printing was focused on the rapid prototyping process and effective way to create physical components of 3D CAD models. Now, t3D printers has been improved to include the ability to print using different materials, such as metals and non-metals, and speed improvements which decrease print time. 3D printers has been also become more accessible to a wider range of users through the production of smaller printers for hobbyists and designers.
