Prusa i3 (i3 stands for third iteration of the design) is the latest design by me. There are countless variations of the design and it became a staple of 3D printing with tens, if not hundreds, of thousands units world wide. You can build simple one for couple hundred dollars or you can chip in more and get the state of the art 3D printer, it’s all up to you.
It’s open functional design allows for quick maintenance. For example if our DumbExtruder™ (LOL) breaks you can clean it in couple seconds! This makes i3 great workhorse 3D printer for your business. Not to mention the ability to upgrade the printer as you wish without manufacturer forcing you to buy a new model!
