Today, 3D printing is used in a wide range of industries, from healthcare and construction to fashion and art.
Types of 3D Printing Technologies and Materials Used
There are several different types of 3D printing technologies, including Fused Deposition Modeling (FDM), Stereolithography (SLA), Selective Laser Sintering (SLS), and Directed Energy Deposition (DED). The materials used in 3D printing vary depending on the technology and application, but common materials include plastics, metals, ceramics, and even food.
Types of 3D Printing Technologies
- Fused Deposition Modeling (FDM) - It is the most commonly used 3D printing technology that works by heating and extruding plastic filament.
- Stereolithography (SLA) - It uses a laser to cure resin into a solid form, layer by layer.
- Selective Laser Sintering (SLS) - It uses a laser to sinter powdered materials into a solid form, layer by layer.
- Direct Energy Deposition (DED) - It uses a laser or electrode to melt metal or plastic material, layer by layer.
- PolyJet Printing - It uses a jetting process to layer liquid photopolymer resin into a solid form.
Materials Used in 3D Printing
- Plastics - Polylactic acid (PLA), Acrylonitrile butadiene styrene (ABS), Nylon, Polycarbonate (PC)
- Metals - Steel, Titanium, Aluminum, Copper, Gold, and Silver
- Ceramics - Porcelain, Alumina, Zirconia, and Silica
- Composites - Carbon fiber, Glass fiber, and Wood fiber
- Resins - Photopolymer resins, Silicone, and Epoxy resins.
It is important to choose the right material and technology for a specific application to ensure the desired result. For example, a high-temperature-resistant material may be required for a functional prototype in the automotive industry, while a biocompatible material may be necessary for a medical implant.
