If you are considering to buy a 3D printer, a 3D Printer Buying Guide is what you need to read. Some decades ago when the earliest devices for 3D printing started to circulate, nobody could imagine that the technology was going to drive a real revolution in the field of manufacturing.
At that period, the only available technique was stereolithography, which utilized print layers of photopolymers modeled through the use of ultraviolet light and gradually superimposed to form more or less faithful reproduction of a 3D object. It was slow, and expensive process (a machine could cost half million dollars) and therefore was unattractive for large-scale application. Nowadays, the situation has drastically changed.
3D Printing Today
The cost of machinery over the years has collapsed, to the point that these days many companies exploit 3D printing to build three-dimensional prototypes of plastic material without having to activate an entire production process ad hoc.
But it is just in current years that the prices of machinery for 3D printing have decreased dramatically, making it possible for the common man to use 3D printing technology.
Suffice it to say that there are companies that have already sold small 3D printers whose price do not exceed one thousand dollars (some even offer it in less than 500 dollars).
3D printing Production Techniques
Of course, the basic concept of 3D printing is interesting: build a 3D model on your computer and input commands, which will order the 3D printer to use the 3D model and forge an accurate representation of the model. Another great option that we focus on this website is 3D Scanning. By 3D Scanning you select an object that you desire to 3D print, 3D Scan it and then you have the object available in a 3D file ready to 3D print.
Most 3D printers use a production technique known as additive manufacturing – the desired object is shaped 3D printing a layer at a time and superimposing it to those layers which already prints. This can do in several ways. 3D printers using laser sintering method create the object by heating the powder metal or the thermoplastic.
In Fused Deposition system, a heated nozzle is used that melts the material, which lies 3D so as to reproduce the 3D model displayed on the computer screen. There are other techniques used mainly in industrial environments, such as the Laminated Object method, which involves stacking thin layers of material, which are engraved by laser from time to time.
There are several methods which can use in 3D printing, for reproducing the image of an object, very realistically. Different organizations and industries use the method which is best suited to meet all the needs of their business.
