The term “additive manufacturing” references technologies that grow three-dimensional objects one superfine layer at a time . Each successive layer bonds to the preceding layer of melted or partially melted material. ... Or, a laser or electron beam selectively melts or partially melts in a bed of powdered material.
What are the various methods and technologies used in additive manufacturing?
By using various techniques the printer builds the 3D geometry by constructing a thin 2D plane layer by layer. There are seven main categories of AM technologies viz Vat photopolymerisation, Material Extrusion, Material Jetting, Binder Jetting, Powder bed fusion, Direct energy deposition and Sheet lamination .

Why is it called additive manufacturing?
The term additive manufacturing comes from the process of how objects are created in 3D printing. ... To simply answer the question “Why is it called additive manufacturing?”, it is because the build process adds instead of subtracts raw material .
Why use additive manufacturing What materials can be used What are the classification of additive manufacturing?
A wide variety of metals and metal alloys are used for additive manufacturing, including gold and silver, stainless steels and titanium amongst others. These can be made to create a variety of different metal parts, ranging from jewellery to aerospace components.
What is additive vs subtractive manufacturing?
Subtractive Manufacturing. Additive manufacturing processes build objects by adding material layer by layer, while subtractive manufacturing removes material to create parts .

What are the criteria supporting the use of additive manufacturing?
The motivations to use Additive Manufacturing are grouped into four criteria: integrated design, individualization, lightweight design and efficiency .
What is difference between CNC and additive manufacturing?
Subtractive vs Additive Manufacturing. They key difference between 3D printing and CNC machining is that 3D printing is a form of additive manufacturing, whilst CNC machining is subtractive . This means CNC machining starts with a block of material (called a blank), and cuts away material to create the finished part.
How do you classify am processes?
Classification of AM processes: Liquid polymer system, Discrete particle system, Molten material systems and Solid sheet system .
