General information
The 3D printing process creates a three-dimensional structure from a model computer-aided design (CAD), typically by applying layer by layer of material successively. The word 3D printing encompasses a range of processes in which material under computer control is joined or solidified to create a three-dimensional object. somehow it has influenced security problems like weapons proliferation, anyone can make his own weapons.
Technical information
The method also begins on a digital 3D model-the actual object’s blueprint. this model is sliced into thin, 2 dimensional layers by the printer’s programe and then converted into a series of machine language instruction (G-code) for the printer to execute. the way a 3D printer operates from here differs according to process. For example, desktop FDM printers melt and disassemble plastic filaments and lay it down onto platform through nozzle.
History in formation
In 1986, Charles “Chuck” Hull was granted a patent for his device and his company , 3D system corporation , released the first commercial 3D printer . The technology used to date by most 3D printers – especially hobbyist and consumer models – is fused deposition modelling , a special plastic extrusion developed in 1988.
Impact of technology
It is the greatest example of disruptive technology as this technology has been evolving for the past 3 decades. Their are many positive and negative impacts of this on society like cost reduction and the negative one is copyright issues.
