- Abstract (EN)
- Selective Laser Melting (SLM), also commonly referred to as laser powder bed fusion (LPBF), has become a widely adopted technology in metal additive manufacturing for both industrial and research applications [1]. However, many commercial LPBF systems are based on closed hardware and software architectures, which limit transparency, process monitoring, and direct parameter manipulation during ongoing builds [2]. While recent industrial machines increasingly provide standardized interfaces such as OPC UA for monitoring purposes [3], fine-grained, layer-wise process control remains restricted. The One Click Metal MPrint+ exemplifies this paradigm by relying on proprietary container-based job execution prepared using commercial software tools such as Autodesk Netfabb or Autodesk Fusion 360 [4]. This contribution presents an alternative approach that enables user-defined control of the MPrint+ system through a custom-developed G-code handling framework. Instead of executing complete print jobs as opaque containers, the proposed method establishes a direct network connection to the printer using its gRPC interface. Externally generated G-code is extracted, processed, and transmitted layer-wise to the machine, enabling direct interaction with the build process beyond standard job execution. The approach allows controlled variation of process parameters such as exposure strategies, hatch patterns, or recoating behavior during an ongoing build, thereby supporting efficient design-ofexperiment studies without requiring multiple independent print jobs [5,6]. In addition, individual G-code commands can be executed interactively, enabling didactic use cases in which machine behavior can be directly observed and linked to abstract toolpath descriptions.
