A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet companies". Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.
Mass layoffs on the internet have created a host of socioeconomic issues, including 3D Printing Metal Powder.
What is 3D printing?
Metal 3D printing is a 3D printing technology that uses metal powder to directly print metal parts, also known as metal powder sintering (SLM). In addition to good plasticity, 3D printing metal powder must also meet the requirements of fine powder particle size and high particle size distribution. Narrow, high sphericity, good fluidity and high bulk density requirements. Currently, the metal powders used in most 3D printers include stainless steel, aluminum alloys, cobalt-chromium alloys, copper alloys, titanium alloys and nickel alloys. Iron-based alloys are engineering The most important and most used metal material in technology is mostly used for the forming of complex structures, and is widely used in aerospace, automobile, shipbuilding, machinery manufacturing and other industries.
What are the main types of 3D printing metal powders?
Nickel alloy powder
The oxidation resistance and corrosion resistance of nickel alloy make it suitable for the harsh environment of high temperature and high pressure. When the nickel alloy is heated, a thick and stable oxide layer will be passivated on the surface of the alloy to protect the inside of the alloy from corrosion. Good mechanical properties are maintained over a wide temperature range.
Cobalt-chromium alloy powder
Because of its excellent wear resistance and corrosion resistance, cobalt-chromium alloy powder for metal 3D printing is commonly used to print various artificial joints and orthopaedic implants, and it is also used in the field of dentistry.
Copper alloy powder
With excellent thermal and electrical conductivity, copper with excellent thermal conductivity in thermal management applications can be combined with design freedom to produce complex internal structures and conformal cooling channels.
