• 3d printing is a process of making a 3dimensional solid object of virtually any shape from a digital model.

• 3d printing is achieved using an additive process, where successive layers of material are laid down in different shapes.

• It is also called RAPID PROTOTYPES

What is 3d printing?

Additive Manufacturing:

The term additive manufacturing refers to technologies that create objects through a sequential layering process. Objects that are manufactured additively can be used anywhere throughout the product life cycle,

3D PRINTING TECHNOLOGY:

Stereolithography

Selective laser sintering (SLS)

Multi-jet modeling (MJM)

Inkjet 3d printing

• Stereo lithography is a process for creating three-dimensional objects using a computer-controlled laser to build the required structure, layer by layer.

• It does this by using a resin known as liquid photopolymer that hardens when in contact with the air.

Stereolithography

• It is an additive manufacturing layer technology which involves the use of a high power laser (for example, a carbon dioxide laser) to fuse small particles of plastic, ceramic, metal or glass powders into a mass that has a desired three-dimensional shape.

• The laser selectively fuses powdered material by scanning cross-sections generated from a 3-D digital description of the part (for example from a CAD file or scan data) on the surface of a powder bed.

Selective laser sintering (SLS)

• This again builds up objects from successive layers of powder, with an inkjet-like print head used to spray on a binder solution that glues only the required granules together.

• Multijet modeling is also known as thermo jet

Multi-jet modeling (MJM)

Multi-jet

• It creates the model one layer at a time by spreading a layer of powder (plaster, or resins) and inkjet printing binder in the cross-section of the part.

• This technology is the only one that allows for the printing of full color prototypes.

WHY 3D PRINTING?

APLLICATION OF 3D PRINTING :

Aerospace industry: Like many industries, aerospace industry is increasingly adopting3d printing technology to develop air crafts parts in the pursuit of Trimming down manufacturing cost.

APLLICATION OF 3D PRINTING :

Education:• Engage 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.

APLLICATION OF 3D PRINTING :

Healthcare:•Rapidly produce 3D models to reduce operating time, enhance patient and physician communications, and improve patient outcomes.

APPLICATION OF 3D PRINTING

Bussiness:• 3d printing technologies have the potential to change the way business model invention is done

Applications of 3d printing

Architecture:•3D printing architectural models provides the opportunity to reduce the number of steps, improving design time, while retaining fine details of the final architecture plan

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.
