Printing in 3d is only limited by your imagination
Printing in 3d, we have all seen or heard about 3D printing, either from newscasters, journalists, science events or shows, we were astonished and Intrigued at what we had seen, Hey it took us back to the early tv shows like Star Trek where for the first time we would have been introduced to their replicator machine that could magically create objects from nowhere. 3D printers are able to print in plastics, nylon, metal, ceramics and hundreds of other materials, they can be used for 3d printing of nonsensical models like ET or Yoda. 3D printers can also be used to print manufacturing prototypes, quasi-legal guns or pistols, end user products, aircraft engine parts, print food (mind you I,m not sure if I would be tempted) and even human organs using a person’s own cells. How fantastic is that and these 3D printers are available now, and at affordable prices, which are getting cheaper all the time.
We now live in an age that is witness to what many are calling the 3rd Industrial Revolution. 3D printing, more professionally referred to as additive manufacturing, takes us away from the era of Henry Ford mass production line and is bringing us to a new reality of customizable, one off production.Need a new part for your vacuum cleaner or other household appliance? As it is now you would order from your service person who gets it from a distributor, who got it shipped from over seas, most probably China, where they would be mass-produced by the thousands at a time. probably injection-moulded from an expensive mould. In time to come, the beginning of which is already here now, you will be able to 3D print the part in your home or office, from a CAD file you downloaded and if you don’t have the right printer, just print at your local library, copy and print shop or internet cafe.3D printers make use of a variety of differing types of additive manufacturing technologies, but they all share one main thing in common. They create a three dimensional object by building the subject layer by successive layer untill the object is completed, Its a lot like printing in 2 dimensions on a sheet of paper, but with an added 3rd dimension, upwards e.g the Z-axis
Each of these printed layers is a thinly-sliced horizontal cross-section of the eventual object, very similar to multi-layer cake where the cook will make a layer at a time and next layer is made on top of the other until the entire cake is formed. 3D printing uses a similar process but of course a lot more precise.
There are various types of additive manufacturing from FDM printing where material is melted and extruded in layers, one apon the other, to SLS printing where a bed of powder material such as nylon or titanium is “sintered”(hardened) layer apon thin layer with in it untill a model is pulled out of it. Every shaped object created begins with a digital file.
