Introduction

3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material.

It is also known as rapid prototyping, is a mechanized method whereby 3D objects are quickly made on a reasonably sized machine connected to a computer containing blueprints for the object.

3D Printers are machines that produce physical 3D models from digital data by printing layer by layer. It can make physical models of objects either designed with a CAD program or scanned with a 3D Scanner.

The basic principles include materials cartridges, flexibility of output, and translation of code into a visible pattern.

Definition: 3D + Printing = 3D Printing

3D Printing is a phrase used to describe the process of creating three objects from digital file using a materials printer, in a manner similar to printing images on paper.

Printing Process

Printing is a process for reproducing text and images, typically with ink on paper using a print press.

History of 3D Printing

• The technology for printing physical 3D objects from digital data was first developed by Charles Hull in 1984. He named the technique as Stereo lithography and obtained a patent for the technique in 1986.

• While Stereo lithography systems had become popular by the end of 1980s, other similar technologies such as Fused Deposition Modeling (FDM) and Selective Laser Sintering (SLS) were introduced.

Different Methods

Selective Laser Sintering (SLS)

Stereo Lithography

Fused Deposition Modeling (FDM)

Laminated Object Manufacturing

SLS Method

Selective Laser Sintering (SLS) is an additive manufacturing technique that uses a high power laser (for example, a carbon dioxide laser) to fuse small particles of plastic, metal (direct metal laser sintering),ceramic or glass powders into a mass that has a desired 3-dimensional shape).

SLS Method

Stereo Lithography

Stereo lithography is an additive manufacturing process using a vat of liquid UV-curable photopolymer ”resin” and a UV laser to build parts a layer at a time.

Fused Deposition Modeling

Fused deposition modeling (FDM) is an additive manufacturing technology commonly used for modeling, prototyping, and production applications.

Laminated Object Manufacturing

Laminated object manufacturing (LOM) is a rapid prototyping system developed by Helices Inc. In it, layers of adhesive-coated paper, plastic or metal laminates are successively glued together and cut to shape with a knife or laser cutter.

World’s First 3D Printed Plane

As anticipated, this modern technology has smoothed the path for numerous new possibilities in various fields. The list below details the advantages of 3D printing in certain fields.

1.In Medical Field, Surgeons are using 3d printing machines to print body parts for reference before complex surgeries. Other machines are used to construct bone grafts for patients who have suffered traumatic injuries.

2.Architects need to create mockups of their designs. 3D printing allows them to come up with these mockups in a short period of time and with a higher degree of accuracy.

3.3D printing allows artists to create objects that would be incredibly difficult, costly, or time intensive using traditional processes.

3D Printing Capabilities

Auto parts: For example, parts of "Formula 1" car engines, are made by direct laser sintering of metal;

Aircraft parts: F-18 (fight aircraft) tube for the control system environment;

Individual Orthodontics: The company Align Technology uses the 3D Printing to generate accurate individual dental braces for hundreds of thousands of patients worldwide by stereo lithography from 3D-scans of the mouth.
