The technology used for printing physical 3d objects from digital out is

called 3d printing.

What is 3d printing?

TYPES OF 3D PRINTING:There are three types of Printer.

1.SLS 3D Printer.

2.FDM 3D Printer.

3.SLA 3D Printer.

SLS (SELECTIVE LASER SINTERING) 3D PRINTER:

FDM (FUSED DEPOSITION MODELING)3D PRINTER:

SLA (STEREOLITHOGRAHPY)3D PRINTER:

Additive Manufacturing:

The term additive manufacturing refers to technologies that create objects

through a sequential layering process.

General Principles:• Printing:

•Modeling:

• Finishing:

Work Flow:

CAD Preparation (Pre-Process):

3D Printing:

Cleaning 3D Printouts (Post-Process):

Powder Removal:

Heating:

Finishing Touches:

Application Of 3D Printer:1. Design Prototypes:o3-Dimensional Printing concept model, functional

prototypes and presentation models for evaluating and refining design, including Finite Element Analysis (FEA) results and packaging.

Application Of 3D Printer:2. Education:oEngage students by bringing digital concepts into the real world, turning their ideas into real-life 3D color models that they can actually hold in their hands.

Application Of 3D Printer:3. Healthcare:oRapidly produce 3D models to reduce operating time,

enhance patient and physician communications, and improve patient outcomes.

Advantages Of 3D Printer:

Manufacturing Options:3D printing provides a wide variety of manufactured products, including customizable products and even an individual’s personal designs.

Rapid Prototyping:Products can more quickly go from just a design to an actual prototype.

Advantages Of 3D Printer:

Manufacturing Speed:Just like the previous advantage, the manufacturing speed for a large number of final products is equally fast.

Reduced Costs:Even though the initial setup costs are higher, 3D printing has become cheaper than cheap labor in third world countries. Additionally, the costs of 3D printing are still decreasing, with the potential of 3D printers in homes in the near future.

Disadvantages Of 3D Printer:

Fewer Manufacturing Jobs:As with all new technologies, manufacturing jobs will decrease. This disadvantage can and will have a large impact to the economies of third world countries, especially China, that depend on a large number of low skill jobs.

Limited Materials:Currently, 3D printers only manufacture products out of plastic, resin, certain metals, and ceramics. 3D printing of products in mixed materials and technology, such as circuit boards, are still under development.

Disadvantages Of 3D Printer:

Copyright:With 3D printing becoming more common, the printing of copyrighted products to create counterfeit items will become more common and nearly impossible to determine.

Dangerous Items:3D printers can create dangerous items, such as guns and knives, with very little or no oversight.

CONCLUSION:

Nothing communicates ideas faster than a three-dimensional part or model. With a 3D printer you can bring CAD files and design ideas to life – right from your desktop. Test form, fit and function – and as many design variations as you like – with functional parts.
