Introduction to Metal 3D Printing Technology
Metal 3D printing technology is evolving rapidly, encompassing a variety of process technologies, each with its own specific material choices and process characteristics.
Metal 3D printing technology evolved from powder metallurgy, and the materials used are likewise derived from powder metallurgy.
Rayvatek currently uses Laser Powder Bed Fusion (L-PBF) technology.
Laser Powder Bed Fusion (L-PBF)
This laser powder-melting technology uses a high-power fiber laser to sinter metal powder, which is spread evenly using a roller or blade.
The challenge with this technology lies in the poor flowability of the powder, which requires precise control of temperature, spot size, and scanning speed during the sintering process.
This technology is widely used in 3D printing contract manufacturing services, particularly for printing titanium alloy, stainless steel, and aluminum alloy, and is a core technology in industrial-grade metal 3D printing on the international market.
