In the 3D printing facilities with selective powder fusing technology printers, different types of fresh and recovered powder materials are managed. They are visually similar and usually stored in the same type of drums, so it may happen that an operator takes the wrong drum. If a machine is fed with wrong material, the result will be part quality problems, damages in the printer and scrap of expensive material. To avoid these mistakes, the drums can be identified with labels, barcodes or color codes. These are not robust solutions because they are operator dependent. Another solution is RFID identification technology, but it requires expensive hardware and complex software. We are developed a mechanical design that is a simple and robust Poka-yoke mechanism against operator errors.
