3D printing is any of various processes in which material is joined or solidified under computer control to create a three-dimensional object, with material such as liquid molecules or powder grains being fused together. 3D printing is used in both rapid prototyping and additive manufacturing.
3D printing has been growing in the media spotlight in recent years. These additive manufacturing techniques are far from being a brand new technology. This 3D printing method has been used in many professional environments for nearly 30 years.
Also scientists are working on 3D printed cement paste which gets stronger with cracks. This could contribute to huge structures, which can bear negative impacts of natural disasters like earthquakes and fires.
