HISTORY OF 3D PRINTING

• 3D printing was invented in the year 1984 by Charles Hull with the advancements in

printing methods after the invention of inkjet printers in the year 1976.

• Charles Hull is the co-founder, executive vice president and chief technology officer of

3D systems.

CONT...

• 1984

Charles Hull developed the first 3D printer and named the technique as

Stereolithography.

• Later 1990's

Other companies developed 3D printers.

• 2005

Z Corp launched first high definition color 3D printer.

WHAT IS 3D PRINTING?

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

is called 3d printing.

• It is also called RAPID PROTOTYPES.

• The technique used in printing 3D objects is called as Additive

Manufacturing.

ADDITIVE MANUFACTURING:

• It is a method of converting a virtual 3D model into a physical

object.

• The term additive manufacturing refers to technologies that

create objects through a sequential layering process.

GENERAL PRINCIPLES / WORKING:

•Modeling

•Printing

•Finishing

MODELING:• Additive manufacturing takes virtual blueprints from computer aided design (CAD)

or animation modeling software and "slices" them into digital cross-sections for the machine to successively use as a guideline for printing

PRINTING

• To perform a print, the machine reads the design and lays down successive layers of liquid,

powder, or sheet material to build the model from a series of cross sections.

• These layers, which correspond to the virtual cross sections from the CAD model, are joined

together or automatically fused to create the final shape.

• The primary advantage of this technique is its ability to create almost any shape or

geometric feature.

VARIOUS TECHNOLOGIES :

• Stereo lithography

• Selective Laser Sintering (SLS)

• Multi-jet Modeling(MJM)

• Ink jet 3D printing

ADVANTAGES :

• RAPID PROTOTYPING: 3D printing gives designers the ability to quickly turn concepts into 3D

models or prototypes (a.k.a., rapid prototyping).

• CLEAN PROCESS Wastage of material is negligible.(oral ..)

• COMPLEX SHAPE can be produced .

• EASY TO USE No skilled person needed.

• REDUCE DESIGN COMPLEXITY

• CHEAP Cheaper process than any other process.(oral…)

• People in remote locations can fabricate objects that would otherwise be inaccessible to them.

DISADVANTAGES :

L Process is slow

L Components do not have enough strength.

L COST OF RAW MATERIALS

L 3-D printers are still expensive.

L Misuse of technology

L Although 3-D printers have the potential of creating many jobs and opportunities, They

might also put certain jobs at risk .

FUTURE SCOPE

• With today's 3D printers, if you lose your TV remote's battery cover you can print a replacement

battery cover. With tomorrow's, if you lose your remote, you'll be able to print a new remote.

• 3D printers are always getting cheaper and better.

• There is currently research going on to create 3D printers that could print out organs for people

in need of a transplant.

• Within a decade, 3D printers will become commonplace in houses.

The benefits of such technology are endless.

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.
