3D printing, also known as additive manufacturing, is a technology that allows you to create physical objects from digital designs. It works by building up layers of material, such as plastic, metal, or ceramic, to create an object. There are several different types of 3D printing technologies, each with their own advantages and disadvantages. In this post, we will discuss some of the most common types of 3D printing technology.
Fused Deposition Modeling (FDM): This is the most widely used and accessible type of 3D printing. It works by heating a filament of plastic, which is then extruded through a small nozzle to create the object. FDM printers are relatively inexpensive and easy to use, making them a popular choice for home and hobbyist use.
Stereolithography (SLA): This type of 3D printing uses a laser to cure a liquid resin, to create the object. SLA printers are more precise than FDM printers, and are often used to create prototypes and high-quality models.
Selective Laser Sintering (SLS): This type of 3D printing uses a laser to fuse small particles of powder into a solid object. SLS printers can print in a variety of materials such as metals, ceramics, and plastics. This technology is often used for creating functional parts, such as aerospace and automotive components.
Multi-Jet Fusion (MJF): This is an advanced form of 3D printing that uses a print head to jet tiny droplets of material, which is then fused together with heat and pressure to create an object. MJF is known for its high precision, smooth surface finish and high-speed printing.
Binder Jetting: This type of 3D printing uses a print head to jet droplets of a liquid binder, which is then fused together with a powder material to create an object. Binder jetting is known for its high speed, high volume and low cost.
Directed Energy Deposition (DED): This type of 3D printing uses a high-powered laser or electron beam to melt metal wire or powder as it is deposited, building up the object layer by layer. DED is used for building large and complex metal parts, such as aerospace and automotive components.
In conclusion, there are several different types of 3D printing technology, each with its own advantages and disadvantages. FDM printing is the most widely used and accessible technology, it works by heating a filament of plastic, which is then extruded through a small nozzle to create the object. SLA printing is a more precise technology that uses a laser to cure a liquid resin, to create the object. SLS printing uses a laser to fuse small particles of powder into a solid object. MJF is known for its high precision, smooth surface finish and high-speed printing. Binder jetting is known for its high speed, high volume and low cost. And DED is used for building large and complex metal parts. The right choice of technology depends on the object you want to print and the desired final quality.
