What is Additive Manufacturing?

Additive manufacturing refers to a process by which digital 3D design data is used to build up a component in layers by depositing material. The term "3D Printing" is increasingly used as a synonym for Additive Manufacturing. However, the later is more accurate in that it describes a professional production technique which is clearly distinguished from conventional methods of material removal.

Additive vs Subtractive ManufacturingIn subtractive manufacturing we start with stock and remove material to get the net shape (traditional machining).In additive manufacturing we start with nothing and add material to get the net shape.
In additive manufacturing, 3D objects are built by adding material in layer upon layer fashion. Materials ranging from plastics, thermoplastics, ceramics, biochemicals, metals, and concrete can be used for production in this sector. Even work is under process to develop human tissues using additive manufacturing techniques.

Latest Technology in 3D Printing

Every engineer is passionate to learn about latest technology in 3D printing. There are many engineers and scientists out there who are working on new ideas for improved results from 3D printing in all sectors of life. Fast developments and innovations have been observed in 3D printing technology over past few years. With introduction of modern materials in the field of 3D printing, it has become even more interesting for us all. In short, 3D printing has revolutionized the world of design, medicine, construction, robotics and manufacturing.

In this article, I would like to share with you few latest developments and technology in 3D printing sector:

Speed Printing: Previously the technology used in 3D printing was a layer-by-layer strategy (hence the word “additive.”). This was very time consuming and it had some serious disadvantages like waste of time and material, reduction in objects’ ultimate strength and so on. But those days of layer by layer manufacturing are now gone. Engineer…
