How Do 3-D Printers Work? How It All Started?

As prototype technology continues to make new waves, 3-d printers have started showing more progress and innovation than ever before. 3-d printing is essentially a way to convert virtual models in various three dimensions into tangible objects in real life.

How printing happens?

These 3-d printers work by printing one layer of a two dimensional object over the other layer to result in an object of three-dimensional nature. Compared to manufacturing technologies of additive nature, these 3-d printers are faster, more efficient and reasonable in pricing as well. The realm of production application too such printers offer a terrific potential.

Where they are used

The realm and scope of 3-d printers and associated printing is applicable in several segments. These range from metal casting, educational segments, architecture, CAD or prototyping technology, design visualization, health care, geospatial spheres, retail as well as entertainment amongst numerous other verticals across industries. In more complex segments, such 3-d printers and three-dimensional printing is used within paleontology to reconstruct ancient fossils and learn about their origins. In crime scenes, such three-dimensional printing technology is used to reconstruct evidence, which maybe have been damaged heavily.

More accessible

During the 1990s, the costs of 3-d printers used to be quite prohibitive because prototyping technology was still in its infancy. However, now, the costs of 3-d printers have reduced drastically, making it accessible for even medium and small sized businesses. Thus, gone are the days when modern prototyping technologies could only be used within heavy industries. Today, small offices can also make use of such technology via 3-d printers and thus construct new materials and 3d shapes easily.

Advantages involved

There are several unique advantages when it comes to using 3-d printers. The first one is the huge amount of timesavings involved. With such printers you no longer have to design, print or finally attach all the items together. All the individual parts of the three-dimensional model are provided. These come in different materials to help you build your model. There is also a significant cost advantage involved when you use 3-d printers. With 3-d printers, you get to print using a variety of grayscales which is especially useful for segments like consumer electronics. The modeling on such 3-d printers is done as and when the need arises and this enables you to construct a model which has a striking resemblance to the actual design.

How it started

The history of 3-d printers and three-dimensional printing is very fascinating. Right from the first instances of printing on Phaistos discs to modern day 3-d printers, the process has been long, painstaking but successful nonetheless. Intermediary printing techniques like woodblock prints, Intaglio, the printing press, lithography, rotary press, screen printing during the 1900s to photocopying, laser printing in the 1960s to dot matrix printing, inkjet printing to the modern day 3-d printers and printing, it has taken plenty of technology, research and trial and error to realize the successful output of 3d technique printing.
