Nikon SLM Solutions, a German metal additive manufacturing company, has released SLM.Prep, a new data preparation software designed to unify and simplify build setup across all its selective laser melting systems. Developed through a multi-year program shaped by user feedback, SLM.Prep aims to enhance transparency, accuracy, and process control in metal 3D printing.
The new platform consolidates data preparation into a single environment, eliminating the need for multiple programs. It provides detailed visualization of every layer and full slice-level visibility into how each one will be printed, allowing engineers to preview builds in complete detail before production begins. Through advanced laser-spot modeling, the system generates accurate build-time estimations based on Nikon SLM’s proprietary scanner behavior, giving users deeper insight into how scan strategies and parameters influence performance.
For high-productivity systems such as the NXG platform, which uses multi-laser architectures, the software integrates tools that allow visualization of all laser spots moving simultaneously on any layer. Users can test different optic-allocation strategies to optimize for speed, quality, or qualification requirements. When process parameters are adjusted, build times are recalculated instantly. This functionality shortens qualification cycles and supports faster iteration for complex builds involving multiple lasers.
Before its commercial release, SLM.Prep was used by industrial partners including AMEXCI and GKN Aerospace under early-access programs. Both companies reported measurable workflow improvements and increased usability during qualification processes.
“SLM.Prep clearly enhanced our data prep workflow. It is encouraging to see the software’s trajectory and we look forward to further leveraging its full potential,” said Srikanth Purli, Head of Engineering at AMEXCI. Martin Thordén, Vice President of GKN Aerospace Engines, added that “SLM.Prep is a very user-friendly and interactive software, especially when it comes to working with laser sequencing for NXG machines.”
Simon Merkt-Schippers, Executive Vice President of Product Management at Nikon SLM Solutions, said the software was created to increase process transparency and accelerate qualification. “SLM.Prep brings a new level of transparency and confidence to additive manufacturing,” he said. “By giving customers a clear, visual understanding of how each laser interacts during production, we’re helping them move faster from design to qualification — unlocking real productivity gains and reducing time to part.”
Nikon SLM’s approach places software at the center of its hardware ecosystem. The NXG XII 600 platform, among the company’s flagship systems, operates with up to twelve lasers and achieves build rates of roughly 1,000 cubic centimeters per hour. With the new tool’s ability to simulate laser movement and reallocate optics dynamically, operators can better balance productivity with material consistency.
Integrating these functions within one environment supports traceability and simplifies qualification procedures—areas that remain critical for manufacturers producing certified aerospace and energy components. This integration reflects a wider trend in metal additive manufacturing, where process software and machine hardware evolve together to improve reproducibility and lower production costs.
SLM.Prep is available immediately to all Nikon SLM machine owners worldwide. The company has confirmed that future updates will introduce new capabilities based on user feedback, continuing its iterative development cycle.
