3D printing

 

        3D- printing is a revolutionary style of printing that has been making headlines in recent years. This Printing style churns on fully rendered objects rather than 2D sheets of paper. Due to the extra dimensionality of 3d ,there is very much variety as to what can be produced, from children toys to full-blown organs. Charles Hull was a co-founder of  the 3D craze. “ He invented stereolithography, a process that produced a tangible 3D object from digital data. This technology is used to create a 3D model from a picture where users can test a design before investing in a larger version.”-The History of 3D Printing by Armando from allthat3d.com Hull from this perspective was a economic genius. It’s far better to create a mockup of a item to see how it’ll do in a test phase rather than to spend one’s money on a completed project  and face a possible failure. 3D printing’s invention was meant to save money despite the process itself being expensive. 3D printing in action is a  mesmerizing repetitive processes of layer of glue and sand taking days to flesh of a digital rendering (personal experience)and it can be seen why it’s so useful. Hull was saving big bucks by creating the 3d printer.

        3D printing was first conceptualized in 1992 ,a printer that created layers of a honey like “glue”, cured  using a photo polymer UV laser to harden  layers. Creating complex parts with precision but still imperfect . 1999 is the start of 3D printing revolution, it was in this year of  3D printing organs were starting to be fleshed out. Engineering organs was possible through the Wake Forest Institute for Regenerative Online pharmacy. Printing organs from patient cells. History in the making. In 2002 an functional animal kidney was created, as being made of the animal’s cells there was far risk of rejection. Rejection of a donor organ could mean life and death in humans, and it’s likely to reject a organ despite the immune-suppressant doctors give to prevent it, so this technology could potentially save lives. “The latest step toward 3D-printed replacements of failed human parts comes from a team at UC San Diego. It has bio-printed a section of spinal cord that can be custom-fit into a patient’s injury.The scientists first printed out small implants made of softgel and filled them with neural stem cells, again using a printer. The implants were then surgically placed inside a tiny gap in a rat’s spinal cord. Over time the new nerve cells and axons grew and formed new connections across the cut spinal cord of the animal.”- “Bio Printers Are Churning Out Living Fixes To Broken Spines” by Eric Niller Wired.com. 3D printers have come such a long way. From kidneys to the precision of creating spinal cords and restoring partial limb movement in those once paralyzed.Creating Spinal cord fixes is absolutely on joke, as it the spine is one of the most complexly sensitive structures in the body. 3D printing is an amazing thing.
