3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
Josef Průša was a core developer of the RepRap project who had previously developed a PCB heated "print bed". He adapted and simplified the RepRap Mendel design, reducing the time to print 3D plastic parts from 20 to 10 hours, changing to the use of two Z-axis motors to simplify the frame, and including 3D printed bushings in place of regular bearings.
A desktop FFF printer made by Stratasys. Fused deposition modeling was developed by S. Scott Crump, co-founder of Stratasys, in 1988. [6] [7] With the 2009 expiration of the patent on this technology, [8] people could use this type of printing without paying Stratasys for the right to do so, opening up commercial, DIY, and open-source 3D printer applications.
IBM developed, manufactured and sold hammer-based impact printers that used either type bars, a chain, a train, or a band to create printed output from 1959 till 1999, replacing the older print drum technology,. Over the course of this time they produced a wide variety of these line printers. This article will detail the most significant ones.

In 1994, she officially divorced Gucci. As part of the divorce settlement, Gucci agreed to pay Patrizia an annual alimony of $1.47 million. [15] By law, she was no longer allowed to use the Gucci surname, but she continued to do so anyway, stating, "I still feel like a Gucci – in fact, the most Gucci of them all." [16] [17] [18]
Wide-format printers usually employ some variant of inkjet or toner-based technology to produce the printed image; and are more economical than other print methods such as screen printing for most short-run (low quantity) print projects, depending on print size, run length (quantity of prints per single original), and the type of substrate or ...
