Hi readers! I hope you are doing well and finding something new. Today the topic to be discussed is – Types of metal 3D Printing. Metal 3D printing is a modern method of manufacturing in which solid metal parts are built up from a succession of thin metal layers of powder, wire, or sheet materials.It has been widely used in aerospace, medical, automobile, and construction parts like this aerospace bracket, which is an implant customized for a particular patient, and high-performance automobile components. Metal 3D printing is not a subtractive manufacturing process and brings no waste of the material during the production process while it gives the designer full design control.
Among those key technologies are Powder Bed Fusion, or PBF, which fuses metal powder using lasers or elect ...
Hey students! Welcome to another episode of the MQ gas sensor series. Today, we are interested to learn about the high-performance sensor that is used to detect the presence of benzene gas. This is the MQ138 gas sensor and it instantly detects the target gas because it has tin dioxide as the sensing element. Usually, it can detect multiple gases and is considered as the Volatile organic compounds (VOC) sensor but the most significant target gas of this sensor is benzene therefore, we’ll pay attention towards the discussion of the benzene detection through this sensor. Many features of this sensor resemble other members of the MQ gas sensor series and we’ll read its basic features and specifications in detail.
In this article, we’ll initiate the discussion with the basic introduction of t ...
Wave soldering is a widely used mass soldering process in the manufacturing of electronics, especially for through-hole elements and intricate technology printed circuit boards. In this method, a PCB is ignored, and a wave of melted solder permits solder joints to form on vulnerable part leads and pads at the same time. While wave soldering is effective and cost-efficient for high-volume manufacture, it is also liable to certain flaws if the method parameters, textiles, or patterns deliberation are not handled carefully.
Wave soldering defects in PCB assembly refer to general soldering flaws, such as spanning, defective solder, voids, and cold joints, that happen during the wave soldering process and can negatively affect the electrical execution, reliability, and long-term endurance of p ...
Hello friends, I hope you are all good. In our previous lecture, we discussed the SI Base Units in detail and today, we are going to discuss the units derived from these base units. In 1960, the International Committee conference was held and they presented the measurement units that are used to measure all quantities worldwide.SI units are used to make accurate and precise measurements.SI units are the set of seven basic units called base units and all other units are derived from these base units and called derived units. A set of seven base units is used to measure the physical quantities but derived units are used to measure the complex quantities other than physical quantities. SI units play an essential role in modern technology and sciences.

Metalworking, a craft embedded in the core of human civilization, has played an important role in shaping our history and technological advancements. From the ancient artisans who meticulously forged metal objects to the modern engineers pushing the boundaries of materials science, the art of metalworking has stood the test of time. Let’s explore this intricate craft, tracing its evolution from ancient times to the cutting-edge innovations of the modern era.
A Glimpse into Metalworking's Illustrious Past
The tale of metalworking begins in the annals of ancient civilizations such as Mesopotamia, Egypt and China, where skilled craftsmen honed their techniques to manipulate metals for tools, weapons and adornments. Through hammering, casting and forging, these early metalworkers laid th ...

Hey fellow! Welcome to the next article on the MQ series of sensors, and today our focus is on the MQ-8 which is used to sense the presence of hydrogen gas. We know that hydrogen is a colorless, odorless, and tasteless gas that humans can not sense easily. It is not toxic like carbon monoxide and other such examples but still, the excess presence of this gas can be life-threatening because it is highly flammable. The air is a mixture of different gases and hydrogen gas when combined with some specific gases, can be harmful to life. In the presence of a bare flame or other ignition material, hydrogen can start the ignition, and here, the duty of sensors like MQ-8 starts. We’ll examine the basic information about this sensor in detail.
In this article, we’ll start reading about the basic in ...
Hi readers! I hope you are doing well and want to learn something new. Have you ever asked why our homes feel warmer when it’s cold and cooler when it’s hot out? Welcome to learn some of the secrets of HVAC Systems. Today, we will learn about the HVAC System.
Specific requirements of HVAC refer to all installations providing comfort as well as keeping a good air condition indoors for residential, commercial, and industrial buildings. It discusses the necessary components for comfortable air in your home: temperature, humidity, and cleanliness through heating, cooling, and fresh air. Most HVAC systems are based on thermodynamic principles and operate using the refrigeration cycle to transport heat through the phases of heat transfer by compressing, condensing, expanding, and evaporating re ...
The printed circuit board (PCB) is the backbone of electronic circuits, and for complex circuits, multi-layer PCBs are utilized to enhance productivity. PCB drilling is a crucial process, especially in multilayer PCB production, and involves precise via creation through laminate material. We know that vias are important conduits that bridge the gaps between multiple layers of PCBs. These are considered the conductive connections in a PCB, especially if it has multiple layers. Without vias, the multilayer PCBs have limited design flexibility and are impractical. In PCB manufacturing, there are multiple drilling types, but today I am going to discuss the comparison between the two most important methods, i.e. mechanical drilling and laser drilling.The appropriate drilling technique selection ...
Hi, friends I hope you are all well this topic we can discuss the main concept of velocity, the velocity time graph. Understanding how things move is key in physics, and velocity-time graphs play a big role in this study. These graphs show how fast an object is going at different times giving us an easy way to look at things like speed changes, distance travelled, and the pushes or pulls involved. For college students, getting good at reading and using these graphs matters a lot. It helps them do well in class and gives them a better grasp of the rules controlling how stuff moves in the world around us.
velocity-time graphs have many uses: they help scientists and engineers model how objects move, guess where they'll be later, and study how different forces affect them. Looking at the gr ...
