PRINTING Printing is a process for reproducing text and images. DEVICE USED –PRINTERTypes Of Printers Dot matrix Ink Jet Laser Lcd
HISTORY OF PRINTING In 1953The first high-speed printer was developed by Remington-Rand . In 1964The first dot matrix printer was marketed by IBM. Later laser (1969) and inkjet printers (1976) came into being. Now it’s the period of 3D PRINTERS.
3D PRINTING It is a method of converting a virtual 3D model into a physicalobject. Additive Manufacturing Technology where a 3D object iscreated by laying down successive layers of material Rapid Prototyping Technology i.e Objects are created usingthree dimensional files using software CAD and a devicecalled 3D printers.
3D PRINTERS 3D printers allow designers to quickly create prototypes oftheir designs, rather than just two-dimensional pictures.
HISTORY OF 3D PRINTERS1984Charles (Chuck) Hull developed the first 3D printer and namedthe technique as Stereo lithography.1993MIT used 2D Inkjet printing technology to 3d printers ,named itas 3 Dimensional Printing techniques.1995Z Corporation obtained an exclusive license from MIT andstarted to develop 3D printers for the general market.
HISTORY OF 3D PRINTERSLater 1990’sOther Companies developed 3d printer’s.2005Z Corp launched first high definition color 3D printer.2006Cornell University introduced the first open source 3D printer(RERAP).2010The first 3D printer was introduced that could produce functionalprototype parts.
URBEE 2010Urbee the first prototype car was presented. This is the firstcar ever to have its entire body printed out on a giant 3Dprinter.It has three wheels, and two seats.
3D CHOCOLATE PRINTERIn Jul, 2011Led by the University of Exeter,The University of Bruneland application developer Delcam,researchers in UKhave presented the worlds first3D chocolate printer.
WORKING You only need a printer, raw material, and software to tell theprinter what to print.
STEP 1 (CAD FILE IS CREATED)
STEP 2The CAD file is exported to a 3D printing machine.
LAYER BY LAYER
STEP 3-ACTUAL OBJECT
TYPES OF 3D PRINTING TECHNOLOGIESThere are four different processes that are all referred to as “3Dprinting.Their main differences are found in the way layers are built tocreate parts.Selective laser sintering (SLS)InkjetFused Deposition Modeling (FDM)Stereo lithography (SL)
APPLICATIONSAREAS OF APPLICATION OF 3D PRINTERS Industrial design Automotive and aviation industries Architecture FOOD INDUSTRY Medical Industries Jewelry Footwear Engineering and construction
INDUSTRIAL DESIGN Designers use 3D printers to quickly create productmodels and prototypes.
AUTOMOTIVE AND AVIATION INDUSTRIES Automotive and aviation industries use 3D printers to makebody parts.
ARCHITECTURE Artists can create models of their projects.
FOOD PREPARATION In food preparation, to apply items in liquid or paste form suchas cheese, icing, and chocolate.
MEDICAL INDUSTRY Physicians can use 3D printing to make hearing aids, artificial teeth,and bone grafts.
OBJECTS MADE WITH 3D PRINTERS
ADVANTAGES RAPID PROTOTYPING: 3D printing gives designers the ability to quicklyturn concepts into 3D models or prototypes (a.k.a., rapid prototyping). Clean process. Wastage of material is negligible. Complex shape can be produced . EASY TO USE No skilled person needed. CHEAP Cheaper process than any other process. Allow more design iterations to choose from. People in remote locations can fabricate objects that would otherwise beinaccessible to them.
DISADVANTAGES Process is slow Components do not have enough strength. 3-D printers are still expensive. Although 3-D printers have the potential of creating many jobsand opportunities, they might also put certain jobs at risk .(for example, you can make your toys at home so toy stores andtoy makers might go out of business).
FUTURE With todays 3D printers, if you lose your TV remotes batterycover you can print a replacement battery cover. Withtomorrows, if you lose your remote, youll be able to print anew remote. 3D printers are always getting cheaper and better. There is currently research going on to create 3D printers thatcould print out organs for people in need of a transplant. Within a decade, 3D printers will become commonplace inhouses.The benefits of such technology are endless.
