OUTPUT devices
3D printer
A machine which allows the creation of physical objects from a 3-dimensional digital model, typically by laying down many thin layers of a material in succession
cheap manufacturing, Quick production, less waste, better quality, accessibility, sustainability, new shapes and structures, win business
Expensive equipment and materials, only photopolymers, materials limited to thermoplastics, filament required, rough surface, Limited biomaterials suite
Inkjet printer
-
Lower initial cost, easily portable, better graphical output, lesser hazards compared to laser printer, don't produce ozone and violate compounds
higher printing cost, slow as little buffer capacity, ink can smuggle, if not used for a long time, printing head can get jammed or ink can get damaged
Laser jet printer
Laser printing is an electrostatic digital printing process. it produces high-quality texts and graphics (and moderate-quality photographs)
by repeatedly passing the laser beam over a negatively charged cylinder called a ''drum''
it is a very fast printer, printing costs less than an inkjet printer can print high resolution, makes no noise during the printing process, maintenance time span is longer, very high efficiency
maintenance is expensive, very bulky and difficult to repair, has health hazards.(gases like ozone, nitrogen, oxide, carbon monoxide) they also emit Ultraviolet radiation which may damage your eyes

LCD projector
It is a type of video projecting for displaying video, images or computer data on a screen or other flat surfaces. To display an images, LCD light projectors typically send light from a metal-halide lamp through a prism of series of dichroic filters that separate the light to three polysilicon panels-one each for the, red, green and blue components of a video signal
More light efficiency than DLP, trends to produce a sharper image, more accurate color, 1000 lumen LCD is more preferred than 1200 lumen DLP 3LCD projectors can project bright vivid images with a low output lamp

Dot matrix printer
is a type of computer printing which uses a print head that moves back-and-forth,or in an up-and-down motion on the page and prints by impact,striking an ink-soaked cloth ribbon against the paper
low purchase cost and cheap to operate,just new ribbons rugged and low repair cost can handle multi part forms
noisy and has low resolution: can see the dots making up each character, not all of them can do color: color looks faded and streaky
