该论文已在赫尔辛基举行的第28届CIMAC世界大会上发表，论文的版权归CIMAC所有。 Although 3D (metal) printing is not a brand new technology it is currently seeing some tailwinds. There is a strong need for building prototypes faster and almost a hype to produce parts without any limitations, rethinking traditional ways of component design and manufacturing. The target in a competition between the big players of all industrial areas is to be the frontrunner, implementing 3D metal printed parts into serial production. This technology is able to break boundaries of conventional design and manufacturing. GE is making great progress with metal additive manufacturing in multiple areas. This article will give an overview on the actual status in printing technologies, identification criteria for components targeted for serial production, with a focus on the area of reciprocating engines. GE is targeting to serialize this technology to lever all the advantages and new option at its best. There for a radical new design process needs to be implemented to use the potential of this technology and make it cost competitive compared to conventional manufacturing technics. The article will describe the new approach, from design to prototype and finally serial production, shows pro’s and con’s and what new additional selection and design criteria needs to be considered. A huge variety of different parts and assemblies for serialization have already been identified but just the tip of the ice berg is seen, the next level will go in a systematic approach across the current component fleet. Main interests are high chip volume, complex assemblies or weldings, intense machining hours, with the additional target to produce at lower cost. Near future trials with hybrid printing, a combination of different materials & properties, will potentially offer us a complete new level of design combinations and possibilities. Crucial for the success of this technology is to re-imagine the design process and close out boundaries that have been forced into the heads of the engineers.
