On Thursday, February 7, 2019, Additive Industries announced the finalists of Additive World Design for Additive Manufacturing Challenge 2019. From a group of 121 contestants, both professionals and students, 3 finalists were selected per category. “The redesigns submitted from all over the world and across different fields like automotive, aerospace, medical, tooling, and high tech, demonstrated how product designs can be improved when the freedom of additive manufacturing is applied. This year again we saw major focus on the elimination of conventional manufacturing difficulties, minimization of assembly and lowering logistical costs. There are also interesting potential business cases within both categories’ says Daan Kersten, CEO of Additive Industries.
This year, in the professional category, Carbon Performance Limited (the UK) shows how the hyper-performance suspension upright, one of the most critical load bearing components of the sport car, can get a 30% weight reduction, in contrast to any conventional upright, by using topology optimization. Another professional, K3D from the Netherlands, improved the performance of the old design of the cutting dough knife (food tech), which is attached to a robot, by optimizing it for additive manufacturing. Besides solving such problems as stickiness of the dough during the cutting process and uneven depth of each cut, K3D also manages to save up to 90% of the weight & reduce the production price by using the redesigned additive manufactured dough knife. The third finalist of the professional category, Mr. Kartheek Raghu, from the Indian company Wipro3D, redesigned the conventional design of a Cold Finger thermal trap for a sublimation process. The cold trap is a device that condenses all vapors, except the permanent gases into a liquid or solid. The redesign contains fine lattice structure that holds cryogenic temperature for longer and therefore improves performance.
