Delta 3D Printer
A 'delta' robot or printer is a robot where a platform is maintained by three pair of arms set in a triangle. The pairs of parallel arms maintain the horizontality of the platform and the movement of these arms displace the platform in the three dimensions. Many solutions exists, but a few are used practically. There are two principles to displace the arms pairs: Each arm pair is installed on a main articulated arm, the movement being generated be the rotation of this main arm. The geometry is the rotational delta or 'Clavel delta' from the name of its inventor. The principle is widely used on 'pick and place' machine in a wide range of industries, from electronic to food. This system can be found in the Delta by Energetic or on the FirePick Delta printers. Arm pairs are attached to carriage sliding along parallel rails. This geometry is called linear delta and is the most frequent type used in 3D printer world, the machines originating the movement being the Rostock and the Kossel. The term 'parallel delta' shall not be used as all robots with parallel arms are called parallel robots. |
