An Introduction to 3d Printers


3D printing refers to any process involved in creating 3 dimensional objects from a computer driven digital model.  it is also referred to as additive manufacturing as it involves laying down successive layers of material until the entire object is created.  Requirements for 3d printing to be carried out include a computer, 3d printer and necessary printing materials.


During purchase, choosing the type of 3d printer to be bought might be difficult.  The printers prices vary.  They can be very expensive while others are affordable.  One buys a 3d printer in accordance with their budget, their purpose for purchase and the printing technique they prefer using.  The 3d printers designed for commercial use are more expensive than those for small scale use.  3d printers made for commercial use are more expensive than those for use at home.


There are different technologies used for printing objects.  some of the technologies used include stereo lithography, fused deposition modelling, selective laser sintering, selective laser melting, electronic beam melting and laminated object manufacturing.


The stereo lithography technology was invented in the 1960s.  It was commonly used in first generation 3d printers. You can read further details about this from the site at It uses a beam of u.v rays.  The u.v rays are focused on the object to be produced.  The object is then filled with a photo-polymer called resin.  When the light hits the resin the person gets a high resolution of the 3d model used.


Fused deposition modelling came into use in the 1980s.  It works by putting a few drops of melted thermoplastic materials together to form a shape.  The materials harden forming 3d objects.


Selective laser sintering on this homepage is somehow similar to stereo-lithography only that it uses powdered material instead of liquid resin.SLS is almost the same as stereo lithography with the difference being that it uses powdered material instead of liquid resin.  The materials it uses are nylon, ceramics, glass, aluminum, silver or steel.  In selective laser melting powder is not converted into granules but rather melted.


Electronic beam melting is a technology that uses electronic beams instead of u.v rays.  Laminated object manufacturing glues together plastic, paper or metal. The objects are then cut with a knife or laser to give them shape


3d printers make it easy to manufacture 3d objects.  This is unlike the 2d printers.


They are also used to produce toys for children.  A variety of objects can be made from them.  The only difference is that these objects are not real.


For those who want to purchase these printers they can search for them in various websites which give them a variety of options to select from.  It is therefore advisable that each person acquires a 3d printer in order to enjoy its benefits.Every one should buy a 3d printer in order to know its benefits.


3d printers have played a role in economic growth.  Those working in these sectors find a source of livelihood by selling these printers.  We should therefore strive to ensure we own one.
