ENGINEERING BEHIND 3D PRINTING

It has been couple of years the curiosity and eager behind the mechanism for 3D printing considerably rose. The working and principle involved with a 3D printing is not very complex or hectic. 

There two most commonly used plastic preferred by 3D printing owner, acrylonitrile butadiene styrene (ABS) and polyactic acid (PLA). While some of the modern printers requires only one of the kind. 

These plastic are available in the form of filaments with standard width that is about 1.75 mm. ABS is most commonly used for making legos is a chemical compound based plastic that is operated at relatively higher temperature. While PLA is extracted from natural resources like sugarcane and corn it has a much glossy texture with high rigidity than ABS. Besides being as a key component in 3D printing it is also used to manufacture compostable packaging. 

Filament of plastic is attached to 3D printer could be highly costly. As 3D printing is getting more popular and people are inclination more and more towards it the prices are getting reduced accordingly.  A clever way to reduce the cost is to adopt the usage of a filament extruder. A filament is inserted in a 3D printer’s printing head just like a cartridge.

3D Printing Helps Make a WheelChair

Often called as additive manufacturing, 3D printing is replacing our conventional ways of manufacturing things and things are built in layers using the digital 3D models. Many kinds of products and materials can be made today with 3D printed models and its applications are still growing. Many analysts predict that in decades to come, it will radically transform our designing and production processes.
Many people have seized the opportunity and designed various products that were made completely according to their specifications and designs. Just recently London-based design firm Layer its new prototype of wheelchair was completely designed using 3D printer. This wheelchair was result of months of research where the designing team questioned various patients and doctors to design the wheelchair that would be comfortably used by them. It was custom design for each patient using their own measurements which means that this wheelchair was just designed for them.
According to Benjamin Hubert, founder of the company Layer, the company is planning to take the plan further and is designing mobile app which will allow users to further customize their wheelchair by choosing colors and adding accessories to their wheelchairs. This wheelchair can be ordered via app and can be delivered within two weeks after manufacturing.
