In contrast, 3D printing process can create objects directlyby adding material layer by layer in a variety of ways, depending on the technology used. Simplifying the ideology behind 3D printing, for anyone that is still trying to understand the concept, it could be likened to the process of building something with Lego blocks automatically. 3

Preview and Download !Researchers estimate that the 3D printing market will reach $7.3 billion in 2016. The primary market – including 3D printing systems, materials, supplies and service – has grown at least 30% each year from 2012 to 2014. The rest of the growth comes from the secondary market, including tooling, molding and castings.

Preview and Download !3D printing was invented with the intent of allowing engineers to create prototypes of their own designs in a more time and in an effective manner. The technology first appeared as early as 1970. Dr. Hideo Kodama Japanese researcher first invented the modern layered approach to stereolithography by using UV light to cure photosensitive ...

Preview and Download !Printing can be done with plastic, resin, and even metal. To print a 3D object, a digital model must be created using Computer Aided Design (CAD). The design is then imported to 3D printing software where the model is sliced into layers to be read by the 3D printer. The printer then produces layers of material one on top of the other.
