Additive manufacturing, also known as 3D printing, is the technique of creating three-dimensional solid items from a computer file.Additive manufacturing technologies are used to create 3D printed objects. An object is built in an additive technique by laying down successive layers of material until the object is complete. Each of these layers can be viewed as a cross-section of the item that has been lightly cut.
Subtractive manufacturing, which involves cutting or bottoming out a chunk of metal or polymer with a milling machine, is the polar opposite of 3D printing.When compared to traditional production methods, 3D printing allows you to create complicated shapes with less material.
Why 3d printers?
Adoption of 3d printing technology has reached the tipping point, with those that have yet to include additive manufacturing into their supply chain joining an ever-dwindling minority. In its early phases, 3D printing was only suited for prototype and one-off manufacturing, but it is rapidly evolving into a production technique.The majority of the present 3D printing demand is for industrial purposes.3D printing technology is destined to revolutionise practically every major industry and affect people’s lifestyles as it advances.
Since the late 1970s, businesses have used 3D printers to make prototypes as part of their design process. Rapid prototyping is the process of using 3D printers for these goals.
It only takes days, not weeks, to go from concept to 3D model to holding a prototype in your hands.
