3D printing is also called as additive manufacturing. It is a fundamentally different way of producing parts compared to traditional subtractive (machining) or formative (moulding, casting) manufacturing technologies. A digital 3D model of the object is converted to a series of thin layer and produces a machine language (G-code) instructions. This G-code is used to print the object.
- Most common 3D printing material used today is plastic
- No special tools are necessary
- Complex shapes can be made more easily
- Since it prints relevant parts only, there is very little wastage of material
- Printed part usually have to go through some further processing to achieve the desired output
