My NetGenEd topic is 3D printing. The 3D printer is a huge step in technology because this printer takes a digital prototype and makes a real prototype out of a certain powder or material the printer uses. Engineers, mechanics, and others have started to use this device to replicate moving parts in project and in cars and to make more efficient parts. Prototypes used to be carefully thought out and tested because of resources.But now the 3D printer uses a powder to create the prototypes so this speeds up the process of trial and error.

"Scientists at Heriot-Watt University are working towards creating the world’s first artificial human livers for drug testing to drastically cut the number of live animals used and **get life-saving medicines into theclinic faster." [1]
