What is 3D Printing ?
3D printing or additive manufacturing is a process of
making three dimensional solid objects from a digital file.
The creation of a 3D printed object is achieved using
In an additive process an object is created by laying down
successive layers of material until the entire object is
1984 - 86
Charles Hull invents 3D printing and coins the
term ―Stereo Lithography‖
First 3D printer built by 3D Systems
First application of 3D printing in the medical field
- creating the human bladder
How it works ?
The 3D printing technique basically has the
following steps :
Forming 3D printable model.
Printing the model.
Finishing of the model
FORMING 3D PRINTABLE MODEL :
A printable model can be formed either
by using a computer Aided Designing
software package or using a 3D
A 3D scanner is an industrial robot
which scans a particular object and
records it’s dimensions and provides
input to the printer.
PRINTING THE MODEL :
Depending on the data provided the printer
lays down several layers of liquid, paper,
polymer, plastic or other material
depending on the material required.
Printer resolution describes layer thickness
and X-Y resolution in micrometers.
3D printers give designers and concept
development teams the ability to produce
parts and concept models using a desktop
Though the printer-produced resolution is sufficient for
many applications, slightly oversized version of the
desired object is removed with a higher-resolution
subtractive process and can achieve greater precision.
Do It YourselfPop-Culture
3-D Bioprinting will allow us for the
printing of cells placed in
predetermined patterns to replicate
human tissues, organs and blood
3D printers are also used for organ
transplantation using the cells of the
patient’s own body.
Other body parts like ears, bones,
heart valve, prosthetic parts can be
made using 3D printers.
Food Industry :
Edible object are created by
syringes injected with edible food.
3D printing food can save both
time and energy when it comes to
experimenting. Even a trained
pastry chef cannot achieve the
perfection that 3D printing can
Produce 3D parts and assemblies made from
Reduces the need for tooling machining, and
More efficient designs.
Reduces the need to maintain an inventory.
Rapid Prototyping : Gives designers the ability to
quickly turn concepts into 3D model or prototype.
Clean Process : Wastage of material is negligible.
Complex shape can be produced.
Easy To Use No skilled person needed.
3-D printers are still very expensive.
Misuse of technology.
Although 3-D printers have the potential of
creating jobs and opportunities, they might also
put certain jobs at risk.
