From now we can experience additive manufacturing in Fab Lab. With the arrival of our first 3d printer, now we have tow different techniques include additive and subtractive manufacturing. Recently and after searching about desktop 3d printers we bought an experimental 3d printer from well known Makerbot company. The Makerbot replicator 2X printer with two nozzles, providing the possiblity of printing two colors at the same time and from this perspective it has an advantage over other similar desktop 3dprinters. The maximum size of prints with this device is 250*160*150 mm. Read more about Makerbot replicator 2X in this page.
