3Dimensions printing is a method of converting a virtual 3D model into a physical object. 3D printing is a category of rapid prototyping technology.

Rapid prototyping technology  It is a automatic construction of

physical objects using additive manufacturing technology.  The first techniques for rapid

prototyping became available in the late 1980’s and were used to produce models and prototype parts.

Types of Rapid Prototyping  Stereo lithography (1986- liquid photosensitive polymers that solidify when exposed to ultraviolet light Photopolymer)

 Laminated Object Manufacturing (layers of adhesive-coated sheet material are bonded together to form a prototypePaper and plastic)

 Selective Laser Sintering (1989-uses a laser beam to selectively fuse powdered materials - Thermoplastics, metals, sand)

 Fused Deposition Modeling (1990-laying down material in layers -Thermoplastics)

 Electron Beam Melting(EBM) (metal powder layer per layer with an electron beam in a high vacuum - Titanium alloys)

 3D Printing

3D Printers  3D printing uses standard inkjet printing technology  It implies close traditional to 2D printing.  To create parts layer-by-layer by depositing a liquid binder

onto thin layers of powder.

Basic process of 3d printing  Although several rapid

prototyping techniques exist, all employ the same basic five-step process. 1.Create a CAD model of the design 2.Convert the CAD model to STL format or ( .PLY,.3DS,.ZPR)

3.Slice the file into thin cross-sectional layers it can be 0.01 to 0.7mm thick cross sectional area

4.Construct the model layer by layer -Layer thickness about 0.1mm -a binder fluid(Photopolymers) is used to fuse the powder in desired areas - A UV flood lamp mounted in print head to cure each layer as it is deposited. -Unbounded powder remains to support the part.

5.Clean and finish the model  Removing the prototype from the machine and detaching

any supports.  Unbounded powder is blow off.

System overview

 3D printers that print with a

variety of materials, such as starch based powder ,ceramic powder & plastic.  It can built complex mechanism

in a single run.  As show in fig the tiny gaps b/w gears can also be produced easily.  The major manufacturer of 3D

printing equipment is Z Corporation.

Cost & Time of a product  Avg. cost is $2-3 per cubic inch  fig shows about 8.75 cubic inch

it cost about $22 to produce.

Architecture  It size about -18*14*20 cm  Printing time-9 hours

Applications  Most current 3D printers are

not used to create final consumer products .  Rather, they are used for prototypes or to produce moulds .  Art & Entertainment  Jewelry  Prototypes

 Metal casting  Geospatial  Medicine  Education and Architecture

Future applications  Organ printing (also known as tissue printing)  we can make our own design automobile parts and other parts

in home or near by shops .

Advantages Create physical 3D models quickly and easily. High definition color models can be created Good tolerance Economical -compared to conventional model

making processes Fastest Print Speed 5x-10x faster than all other technologies Less skilled workers.

Disadvantages  Rough surface finish  It may not be suitable for large sized objects.  3D printers are still expensive  3D printers have the potential of creating many jobs and

opportunities, they might also put certain jobs at risk

Future of 3D printers  Improved accuracy and surface finish  Increased size capacity.  Increase in speed .

 Decrease of cost.

Conclusion 3D printing enable the manufacturer to improve there

designs and get the product to market more quickly than ever. 3D printing is developing relative to the developments of

CNC and 2D printers becoming faster, easier to operate and cheaper prices. There is still lot of growth to be seen in this field in near
