![]() ![]() ![]() The conventional micromachining techniques are unable to achieve true 3D structures and face challenges in manufacturing complex shapes. Several industrial sectors including biomedical, industrial, chemical, aerospace, electronics, communications and energy, have the need to miniaturize their products for various purposes. ![]() The burgeoning field of 3D printing has changed the way products are manufactured in many industries by offering a higher degree of freedom in design and fabrication with a wide range of materials. This popularity is due to the high reusability rate of the powder material, faster production speed, strong functional parts, lower cost, no or minimum support structures, different fields of application and a large range of compatible materials. The powder-based process is one of the most significant and popular class of 3D-printing techniques. The 3D printing could also be categorized based on the primer materials into the categories of liquid-, solid- and powder-based processes. ģD printing is primarily classified into seven categories: (1) binder jetting, (2) powder bed fusion (PBF), (3) directed energy deposition, (4) material jetting, (5) vat polymerization, (6) material extrusion and (7) sheet lamination. Compared to the conventional subtractive manufacturing methods, 3D printing enables high design complexity and shorter design cycle. The 3D-printing revolution has been seen by many as one of the technologies that will form the industrial revolution 4.0. Nevertheless, concerns are raised for applications that subject 3D-printed parts to repeated stress that may cause fatigue failure. Much effort has been made to characterize the durability, surface finishing and mechanical properties of 3D-printed objects. The 3D printing emerges as a viable alternative to conventional industrial production technology. The 3D printing provides unparalleled flexibility that enables layer-by-layer construction of functional parts with complex shapes and geometries. Additive manufacturing, also termed three-dimensional (3D) printing, is a process that transforms the computer aided-design model into a true 3D object using various materials. ![]()
