The Evolution of Printing

3d models]

Additive manufacturing or is it commonly called 3d printing is one of the most advanced technological inventions in the past decade, although it was first invented in 1980’s but the last decade evolved it into an advanced manufacturing technology changing our perceptions about production in future. Let’s discuss how it actually works.
A 3d printer basically turns digital 3d models into a physical solid shape; the shape depends on what the software feeds it. There are some limitations on to what extent the printer produce a 3d output but it usually works when a 3d model is rendered into a 3 dimension physical representation of the design/model. A basic and a typical 3d printer basically works just like our mainstream inkjet printers. It works on building one layer at a time, bottom to top, recurrently printing over the same area by following a process known as Fused Depositional Modeling (FDM). If we keep aside the technological complexities, the process is actually quite simple. Working over a period of hours the printer creates 3d models using a 3d CAD drawing into many cross-sectional and two-dimensional layers. It commendably separates 2d prints that sit on top of another, but without any paper. As an alternative to ink, a 3d printer deposits molten plastic or a form of powder in the form of layers and fuses them together to give it the designated 3d model design. It usually uses an adhesive or mostly an ultraviolet for the fusing purposes.
This technological innovation as claimed by the producers of these printers is very advantageous to people who are looking to make rapid prototypes in hours instead of waiting for days. Although high-end 3d printers are still very expensive, ranging from $25000-$50000. But the claim is that it is 5 times cheaper and 10 times faster than other methods mostly used.
