3D printing and additive manufacturing (AM) has proven a worthy technology in many applications. Apart from potentially impressive geometrical advances in specific applications, the technology also offers direct and local production as well as a greener footprint from a material utilization perspective. The field of large-scale metal 3D printing is progressing slightly slower compared to other disciplines within additive manufacturing. The reasons for this may be related to technology availability, limitations in print complexity, cost levels or limited documentation of the quality. It may very well be a combination of all of the above, but as large-scale metal printing is already adopted in architecture and space, one might argue that everything between those two sectors is more focused on lead time, cost and evaluation of risk. The primary focus of this paper is to examine and document the quality output when 3D printing via the laser cladding process. The materials included in this analysis will represent what is commonly accepted and applied in different industrial sectors. Printing using recycled standard materials will also be investigated. All printed materials will be compared to their respective standard reference with respect to common mechanical and corrosion properties. Furthermore, microstructure and NDT analysis will be conducted in order to clarify and discuss a potential quality gap between print and reference standard. The overall goal is to document these findings for approximately 30 materials in the coming years to establish a reliable model for quality prediction early in the design phase of a new or modified component to be additively manufactured |
