Rapid Prototyping / History / Prototyping Technologies

Rapid Prototyping History of Rapid Prototyping Rapid prototyping is quite a recent invention. The first machine of rapid prototyping hit the markets in the late 1980s. The early rapid prototyping process derived its name from the activities and the purpose for which the earlier machines were utilized. What is Rapid Prototyping? Rapid prototyping refers to…

Electron Beam Melting

Electron Beam Melting: EBM (Electron Beam Melting) can be described as the ‘rapid prototyping’ for metals. It is better known as ‘rapid manufacturing’ method. The parts are manufactured by having the metal powder melted layer by layer through a beam of electron in high vacuum. The parts produced acquire strength, solidity, and are void-free as…

Introduction To Additive Fabrication

Introduction To Additive Fabrication Additive fabrication refers to a class of manufacturing processes, in which a part is built by adding layers of material upon one another. These processes are inherently different from subtractive processes or consolidation processes. Subtractive processes, such as milling, turning, or drilling, use carefully planned tool movements to cut away material…

Air-Powered Car Coming to Hit 1000-Mile Range

The Air Car caused a huge stir when we reported last year that Tata Motors would begin producing it in India. Now the little gas-free ride that could is headed Stateside in a big-time way. Zero Pollution Motors (ZPM) confirmed on Thursday that it expects to produce the world’s first air-powered car for the United…

World’s First Air-Powered Car | Zero Emissions

World’s First Air-Powered Car India’s largest automaker is set to start producing the world’s first commercial air-powered vehicle. The Air Car, developed by ex-Formula One engineer Guy Nègre for Luxembourg-based MDI, uses compressed air, as opposed to the gas-and-oxygen explosions of internal-combustion models, to push its engine’s pistons. Some 6000 zero-emissions Air Cars are scheduled…

Machine Vibration | Causes of Vibration

Machine Vibration What Causes Machine Vibration? Almost all machine vibration is due to one or more of these causes: (a) Repeating forces (b) Looseness (c) Resonance (a) Repeating Forces Imagine a boat anchored in a bay. Waves are slapping the sides of the boat, and as long as the waves continue to act on the…

Mechanical Vibration | Introduction To Machine Vibration | Causes of Machine Vibration

Mechanical Vibration What is Machine Vibration? Most of us are familiar with vibration; a vibrating object moves to and fro, back and forth. A vibrating object oscillates. We experience many examples of vibration in our daily lives. A pendulum set in motion vibrates. A plucked guitar string vibrates. Vehicles driven on rough terrain vibrate, and…

Introduction to Mechanical Vibrations

Introduction to Mechanical Vibrations The study of vibration A body is said to vibrate if it has periodic motion. Mechanical vibration is the study of oscillatory motions of bodies. Vibrations are harmful for engineering systems. Some times vibrations can be useful. For example, vibratory compactors are used for compacting concrete during construction work. Excessive vibration…
