This is a filament deposition delta 3D printer, was designed and built in 2013 using recycled parts from old dot matrix printers and flatbed scanner. FDM (Fused Deposition Modeling) is a layer additive manufacturing (or 3D Printing) process that uses production-grade thermoplastic materials to produce both prototype and end-use parts using a number of thermoplastic FDM materials that can be used for direct digital manufacturing including ABS, PC-ISO polycarbonate and Ultem-9085 for high-temperature applications. A delta robot mechanism was used to move the extruder. It is a type of parallel robot that consists of six parallel arms connected to three parallel sliders at the base. The key design feature is the use of parallelograms in the arms, which maintains the orientation of the end effector which restrict the movement of the end platform to pure translation, i.e. only movement in the X, Y or Z direction.(photos are taken by https://www.facebook.com/BMosbatPhoto)
