With the emergence of high-speed DSP (Digital Signal Processors) and peripherals, new product designers face an increasingly severe threat from electromagnetic interference (EMI). Initially, the issues of transmission and interference were referred to as EMI or RFI (Radio Frequency Interference). Now, a more definitive term, “interference compatibility,” is used instead. Electromagnetic compatibility (EMC) encompasses both … Read more
In high-speed digital signal processing (DSP) systems, electromagnetic interference (EMI) is a critical issue that cannot be overlooked. Due to the high-frequency signal processing and complex circuit layouts involved in DSP systems, the electromagnetic environment becomes more complicated, easily leading to signal distortion, system instability, and even functional failure. Therefore, engineers need to understand the … Read more
3D printing technology, academically known as “additive manufacturing,” is also referred to as additive manufacturing or incremental manufacturing. According to the definition published by the American Society for Testing and Materials (ASTM) 3D Printing Technical Committee (F42 Committee) established in 2009, 3D printing is a method that contrasts sharply with traditional material processing methods, based … Read more
The traditional jewelry-making process is a meticulous and time-consuming endeavor. No one can deny the skill and craftsmanship involved in hand-making rings or pendants; handcrafted personal ornaments always possess some uniqueness. However, the fact is that creating jewelry entirely by hand requires a significant amount of time, patience, and skill. 3D printing technology allows anyone … Read more
Every Week Science Popularization 3DPrinter Introduction 3D printers, also known as three-dimensional printers, where D means dimensions. This printing technology is a type of additive manufacturing technology, which creates three-dimensional (3D) objects by “printing” layers of adhesive materials. The earliest 3D printing appeared in the 1980s, when it was expensive and the number of products … Read more
1. Overview (1) Introduction to 3D Printing Technology 3D printing, also known as additive manufacturing, is a technology that creates physical objects by gradually adding material. Compared to traditional subtractive manufacturing processes, which involve material removal, 3D printing is a “bottom-up” manufacturing method. Computer-controlled additive manufacturing technology first appeared in the 1980s.3D printing technology has … Read more
Source: EETOP. 3D printing can turn 3D modeling files from a computer into physical objects, with a printing process that requires no intervention and precision that far exceeds manual production. It sounds and feels quite cool. Although it has been popular for a long time, it remains mysterious to the general public. Considering that many … Read more
