If you are even a bit interested towards scanning and printing industry, you would have heard of the prominent 3D Printers and scanners, which are high in demand nowadays.

Over the past few years we have concluded that 3D Printing is not a one hit wonder but a very versatile and robust technology that has the potential to change the way we make and sell products. Like any other technology 3d printing comes with its opportunities and challenges and if it has to be used as a replacement for the traditional manufacturing processes it would need to address its challenges as quickly as possible.

Evolution is arguably the most solid theory in modern biology. It has represented the foundation of biological research for centuries now and it’s still the basis over which many present day discoveries are made. Take the human teeth for example: its usefulness is undeniably linked to our evolution as a big, solid food churning species and its appearance is a solid indicator of the evolution of biological processes throughout species. Previous methods of food deconstruction involved a sandpaper like mouth but the Placoderms, a group of fish living some 400 million years ago are believed to be the first to exhibit bony jaw structures. It was thought that these fish had what you’d call “real teeth” but recent analysis from the Australian National University, which employed 3D printing and 3D scanning of a Buchanosteus fish fossil revealed evidence that the group could have represented a transitional link.

Regular metal fabrication needs stamping orremoving metals for creating the desired design. On the other hand, metal 3Dprinting creates objects by buildingeach layer by fusing material together using a programmed laser. It actuallydraws each layer’s shape till the object is completely produced.
