What is 3D Printing?
3D printing is a method of manufacturing or constructing 3-dimensional objects by transferring the data files from your system to the printer. The term “3D printing” can refer to a variety of processes in which material is deposited, joined or solidified by controlling it via computer which helps you to create a three-dimensional object, with liquid molecules or powder grains being fused together typically layer by layer.

Types of 3D Printing Methods and Technologies
It is a process of converting any digital file into a real 3d object. You can make use of any designing software to draw or scan any object you would like to print to get a real object or you can simply download any files from the internet. These Printer objects are formed by the addition and deposition of successive layers of print material and are proven to have great impact in many industries such as medical, science, engineering, aerospace, education and many more.
Material Extrusion (FDM)
Material extrusion is also known as Fused deposition modelling (FDM) which is a common extrusion process and is used by various renowned companies all over the world. In this process the material is drawn through a nozzle, where it is heated and is then deposited layer by layer and its design allows the nozzle to move horizontally while a platform moves up and down vertically after each new layer is deposited. It is a commonly used technique used on many inexpensive, domestic and hobby FDM 3D printers.
Vat Polymerization (SLA & DLP)
Vat Polymerization is a method where you can print 3D objects by using digital light processing which involves exposing liquid polymers to ultraviolet (UV) light to turn that liquid into solids. Firstly you need to create a 3D design in a 3D software program, then, the 3D printer uses digital light processing technology to project the image with UV light onto a vat of liquid polymers layer by layer. This process of draining and exposure to UV light is repeated until the object is complete, when the vat is completely drained it leaves behind the solid 3D object.
Powder Bed Fusion (SLS, DMLS & SLM): A high-energy source selectively fuses powder particles
Powder bed fusion (PBF) methods use either a laser or electron beam to melt and fuse material powder together. Electron beam melting (EBM), methods require a vacuum but can be used with metals and alloys in the creation of functional parts. All PBF processes involve the spreading of the powder material over previous layers. The Powder Bed Fusion process includes the following commonly used printing techniques
- Direct metal laser sintering (DMLS)
- Electron beam melting (EBM)
- Selective heat sintering (SHS)
- Selective laser melting (SLM)
- Selective laser sintering (SLS).
Material Jetting (MJ): Droplets of material are selectively deposited and cured
In this process the material is jetted onto the build surface or platform, where it solidifies and the model is built layer by layer. It involves the material getting deposited from a nozzle which moves horizontally across the build platform. Though the machines involving this process vary in complexity and in their methods of controlling the deposition of material. The material layers are then cured or hardened using ultraviolet (UV) light.
Binder Jetting (BJ): Liquid bonding agent selectively binds regions of a powder bed
The binder jetting process uses two materials, a powder based material and a binder. These binders act as an adhesive between powder layers which is usually found in liquid form and the build material in powder form. A print head moves horizontally along the x and y axes of the machine and deposits alternating layers of the build material and the binding material where after each layer, the object being printed is lowered on its build platform.
Direct Energy Deposition (LENS, LBMD): A high-energy source fuses material as it is deposited
A typical DED machine consists of a nozzle mounted on a multi axis arm, which deposits melted material onto the specified surface, where it solidifies. This process is similar in principle to material extrusion, but the nozzle can move in multiple directions and is not fixed to a specific axis but can be deposited from any angle due to 4 and 5 axis machines which are melted upon deposition with a laser or electron beam. The process can be used with polymers, ceramics but is typically used with metals, in the form of either powder or wire.
Sheet Lamination (LOM, UAM): Sheets of material are bonded and formed layer-by-layer
The sheet lamination processes include ultrasonic additive manufacturing (UAM) and laminated object manufacturing (LOM), where UAM process uses sheets or ribbons of metal, which are bound together using ultrasonic welding and requires additional cnc machining and removal of the unbound metal, often during the welding process. While LOM uses a similar layer by layer approach but uses paper as material and adhesive instead of welding and uses a cross hatching method during the printing process to allow for easy removal post build.
