The 3D printing was invented in 1986 also it was the time which 3D printing started. the person who invented 3D printing is Charles Hull “chuck” also known as the father of 3D printing.
3 Is a method of converting visual 3d model in to physical object. Where a 3D object is created by laying down successive layer of material. the technology has revolutionized the manufacturing proces s, allowing for the production of highly complex shapes and geometries that were previously impossible or very expensive to produce.

Some application of 3D printing technology 6 Aerospace industry Automotive indus t ry Architecture and Construction industry Fashion industry Education and Research industry Healthcare industry
Application of 3D printing on aerospace industry
T he aerospace industry is using 3D printing technology to produce lightweight parts and complex geometries that can withstand extreme conditions. For example, GE Aviation used 3D printing to produce a fuel nozzle for an aircraft engine, which reduced the nozzle's weight by 25% and increased its durability. 8
Application of 3D printing on Automotive industry
The automotive industry is using 3D printing technology to produce custom parts and prototypes quickly and cost-effectively. For instance, Porsche used 3D printing to produce a lightweight seat bracket for its 911 GT3 RS model, which reduced the weight of the car and improved its performance. 10
Application of 3D printing on Healthcare industry
The healthcare industry is using 3D printing technology to produce patient-specific implants, prosthetics, and surgical tools. For instance, doctors at Johns Hopkins Hospital used 3D printing to produce a custom prosthetic jaw for a cancer patient, which improved the patient's quality of life. 12
Application of 3D printing on Architecture and Construction industry
The architecture and construction industry is using 3D printing technology to produce large-scale building components, such as walls, columns, and facades. For instance, Winsun , a Chinese construction company, used 3D printing to produce ten houses in just 24 hours, reducing construction time and costs significantly. 14
Application of 3D printing on Fashion Industry industry
The fashion industry is using 3D printing technology to produce custom footwear, jewelry, and accessories. For instance, Adidas used 3D printing to produce a custom-made shoe for each athlete during the 2016 Rio Olympics, which improved their performance and comfort. 16
Application of 3D printing Education and Research Industry
The education and research industry is using 3D printing technology to produce teaching aids, anatomical models, and prototypes for experiments. For instance, MIT used 3D printing to produce a miniature robotic cheetah that can run and jump, which helped researchers understand animal locomotion better. 18
19 Future Of 3D printing 3D printing technology is evolving rapidly, and its future is exciting. Advancements in materials, processes, and software are expanding the range of possible applications, such as in bioprinting , space exploration, and food production.
conclusion In conclusion, 3D printing technology is transforming the manufacturing process and has a wide range of applications across various industries. Its advantages, such as faster prototyping and customization, make it an attractive option for businesses looking to improve their products and reduce costs. As the technology continues to evolve, we can expect to see more innovative uses of 3D printing in the future.
Electromagnetic interference(EMI) 21 Electromagnetic Interference is disturbance that affects an electrical circuit Caused by induction or outside radiation Can temporary and permanently disrupt circuit components Big design issue for new products
CLASSIFICATION OF EMI 22 INTRASYSTEM EMI EMI problems with in the system one is dealing with. INTERSYSTEM EMI EMI problems ,that occur between two or more systems.
EXAMPLE OF EMI 23 INTERFERENCE AT 2.4 GHZ Why use 2.4GHz? Part of the ISM Band No license needed to design devices in this range FCC originally designated 2.4-2.483 GHz band for microwave ovens Devices and protocols that operate in this band Cordless telephones Baby monitors Bluetooth Wi-Fi 802.11b and 802.11g wireless devices (most routers) Wireless cameras and controllers
Radio frequency interference 24 Two way transmitters, radio stations, amateur radio broadcast Interrupted signal before reaching receiver Results in signal masking and distortion
Testing 25 Compliance tests Performed at the end of design Engineering tests Deals with potential problems in the designing process It is associated with manufacturing quality
HOW DOES EMI WORKS? 26 Causes Electric fields radiating from currents Switching circuits, clocks, natural fields, ect . Coupling of electric fields into circuits and components Unintentional and intentional Effects Causes problems for electronics Loss and disruption of data Growing problem with more advanced devices
Reduction of EMI 27 Both filtering shielding techniques are used to reduce electromagnetic disturbances. To reduce noise due to EMI at sources by EMC oscillators.
