A 3D scanner is a device that analyses a real-world object or environment to collect data on its shape and possibly its appearance (e.g. colour). The collected data can then be used to construct digital three-dimensional models using 3D Printer or any devices.

Delta/Kossel 3D Printers are parametric delta robot 3D printer, built in 2012 by Johann in Seattle, USA, based on his Rostock prototype.The benefit of a Delta is that the moving parts are lightweight so that it’s easier to travel. That results in faster printing with greater accuracy

DLP/SLA use UV light to harden liquid resin and make higher resolution but usually smaller objects.
