What is 3D-Printing?


A conventional 2D-printing involves the process of producing a representation of electronic document (e.g. texts or charts/pictures on computer) on paper with inks via a peripheral, say inkjet printer, and the result is a 2-D visual display on plane physical medium.

A 3D-printing involves the process of reading a computer aided design or 3D-modeling software by a 3D-capable-printer and then create a successive series of cross-sectional layers (e.g. ABS- and PLA-materials) based on the three-dimensional blueprint.

Unlike 2D representation yielded by conventional printers, 3D-printers are capable of constructing virtually any shape by fusing together layers of materials which are being used.




3D Printing Plastic
Currently, there are various types of 3D-printers released on the markets by different developers. These printers may have variable 3D-model constructing systems and feed only on specific materials, but they all bear the same modeling principles by joining together layers of the materials.
