What do you mean by 3D?
3D means three dimension, which describes any object that occurs on a three axis Cartesian coordinate system. A Cartesian coordinate system describes the X and Y axes.
What is 3D printing?
3D printing is known as desktop fabrication or additive manufacturing to deliver three dimensional solid objects from a digital file. This digital 3D model is saved in STL format and then sent to a 3D printer. After sending to 3D printer it will print the design layer-by-layer and form a real object.
How does 3D printing Works?
To print a digital file, first 3D modeling software “slices” the final model into hundreds or thousands of horizontal layers. Then this sliced file is uploaded in a 3D printer, the object can be created layer-by-layer. 3D printer will read every slice or 2D image and creates the object. Finally it blends each layer with visible sign of the layers resulting in three dimensional object. As a result it gives final output as three dimensional object.
3D printing applications and examples:
3D printing application is mainly used in the field of medical industry i.e. 3D printed prosthetics and printing with human tissue, rapid prototyping, architectural scale models and Maquettes, healthcare and entertainment e.g. film props.
Examples of application are listed below:
Reconstructing fossils in paleontology, replicating ancient artifacts in archaeology, reconstructing bones and body parts in forensic pathology and reconstructing heavily damaged evidence acquired from crime scene investigation and so on.
Processes and technologies of 3D printing:
The American Society for Testing and materials (ASTM) group “ASTM F42 –Additive manufacturing” developed a set of standards which categorize the Additive Manufacturing processes into 7 classes are listed below:
- Vat PhotoPolymerization
- Material jetting
- Binder jetting
- Material Extrusion
- Sheet lamination
- Directed energy Deposition
SLS-Selective laser sintering, FDM- fused deposition modelling and SLA- streolithography are the most widely used technologies used for 3D printing
Future of 3D printing:
3D printing process have reduced the time of designers and engineers to conceptualize, create and test prototypes of 3D models. Nowadays 3D printing is rapidly changing with respect to manufacturing industries. 3D printing is comes with new technological aspects where user can upgrade in everyday business decision.
3D printers are easily to handle and cheap to maintain. So user can buy with its best product where they can print or design their own 3D models.
