The machine is realized with a delta kinematic using many components from the consumer/maker area. It can be easily mounted onto a water basin, containing the test object to be scanned. Software control is realized via G-code, as popular in CNC. With additional components, the positioner can be re-configured and re-used as a high-quality 3-D printer.enultrasonic testingsynthetic aperturepositioning3-D printer620658670conference paper
