What is 3D printing?
3D Printing (3DP), also known as Additive Manufacturing, is a form of rapid prototyping technology. It is based on 3D model files and uses bondable materials such as powdery metal or plastic. The objects are constructed through a layer-by-layer printing process.
3D printing is typically achieved using digital technology material printers. It's frequently used in mold manufacturing and industrial design for model creation, and has gradually been employed for the direct manufacturing of certain products, with parts already being produced using this technology. This technology finds applications in various fields, including jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dentistry and medical industries, education, geographic information systems, civil engineering, firearms, and others.
Several types of 3D printing.
- Fused Deposition Modeling (FDM): This is the most common 3D printing technology, which heats and extrudes thermoplastic filament, layer by layer, to build a model.
- Stereolithography (SLA): This technology uses an ultraviolet laser to "draw" each layer on the surface of a liquid resin. The resin hardens under the laser, building up the model layer by layer.
- Digital Light Processing (DLP): Similar to SLA, but it uses a digital light source, such as a projector, to harden a whole layer of resin at once.
- Selective Laser Sintering (SLS): This technology uses a laser to sinter powdered material (like nylon or metal powder) into a solid, building up the model layer by layer.
- Powder Bed Fusion (PBF): This is a type of metal 3D printing technology that uses a laser or electron beam to melt metal powder into a solid.
- Material Extrusion: This technology uses an extruder to push out material, forming the model.
- Laminated Object Manufacturing (LOM): This technology cuts and bonds materials (like paper or metal foil) together to form a model.
- Bioprinting: This is an emerging 3D printing technology that uses biological materials (like cells and biocompatible materials) to print tissues and organs.
These are some of the main types of 3D printing, each with their own advantages and applications.
