3D PRINTING AND 3D BIO PRINTING

3D printing or additive manufacturing is a process of making a three-dimensional 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. 3D printing is also considered distinct from traditional machining techniques, which mostly rely on the removal of material by methods such as cutting or drilling (subtractive processes). The term additive manufacturing refers to technologies that create objects through sequential layering. Objects that are manufactured additively can be used anywhere throughout the product life cycle, from pre-production (i.e. rapid prototyping) to full-scale production (i.e. rapid manufacturing), in addition to tooling applications and post-production customization.

WHAT IS 3D BIO PRINTING?

3D bio printing is the process of generating spatially-controlled cell patterns in 3D, where cell function and viability are preserved within the printed construct. Using 3D bio printing for fabricating biological constructs typically involves dispensing cells onto a biocompatible scaffold using a successive layer-by-layer approach to generate tissue-like three-dimensional structures. Given that every tissue in the body is naturally compartmentalized of different cell types, many technologies for printing these cells vary in their ability to ensure stability and viability of the cells during the manufacturing process. Some of the methods that are used for 3D bio printing of cells are photolithography, magnetic bio printing, stereo lithography, and cell extrusion.

EXAMPLES OF 3D BIO PRINTED EXPERIMENTAL ORGANS.

These Examples include ears, fingers, kidney and other organs essential and vital for human survival.

ADVANTAGES OF 3D PRINTINGThe Advantages of 3D printing is a follows:Digital Object Storage: Allowing a

number of parts of machines to be stored online and print whenever needed

Digital Object Delivery: items will then be able to be delivered directly across the net.

Reduced Material Wastage.Increased Customization: We can

customize our item the way we want it to be.

More Local manufacturing.

ADVANTAGES OF 3D BIO PRINTING.

The potential benefits of 3D culture systems, especially those that contain multiple cell types, are recognized in several fields, including oncology, stem cell and developmental biology, cardiology, and hepatology.

Bio printed tissues are created without dependence on integrated scaffolding or hydrogel components, they have a tissue-like density with highly organized cellular features, such as intercellular tight junctions and microvascular networks.

There would then be no need of organ transplantation, need an organ? Print it!

We can then produce organs such as hearts, kidneys, ears, fingers and other vital organs essential for human survival with just a click.

THE VERY FIRST INVENTOR OF 3D PRINTER

O In 1983, Hull 3D printed a small cup, the first-ever object created with additive technology. The success of Hull's process served as a catalyst to his founding of 3D Systems in 1986.

O Hull continues to lead the 3D printing revolution as 3D Systems' Chief Technology Officer, celebrating 30 years of continuous 3D printing innovation and presiding over seven different 3D print technologies, more than 100 materials and 1,700 patents.

O Since 1973, the National Inventors Hall of Fame has been honoring the individuals who have conceived, patented and advanced great technological achievements. To be inducted, candidates must hold a United States patent that has contributed significantly to the nation's welfare and the advancement of science and useful arts.
