Solukon Launches SPR-Pathfinder PRO for Advanced LPBF Depowdering Simulation
Solukon has released SPR-Pathfinder PRO, an upgraded software for simulating powder removal from complex 3D-printed parts, featuring enhanced resolution and particle simulation capabilities.
German manufacturer Solukon has introduced SPR-Pathfinder PRO, an advanced software package designed to simulate and plan powder removal from components manufactured using laser powder bed fusion (LPBF). This new edition is particularly aimed at optimizing the depowdering process for intricate geometries, including those with fine internal channels and densely packed surfaces.
The PRO version significantly enhances simulation capabilities by removing previous voxel limitations and increasing the particle simulation count to one million. This allows engineers to visualize internal powder movement before printing, identifying potential powder traps within complex designs at an early stage. The software also offers cross-sectional views along X, Y, and Z axes, along with adjustable model transparency, enabling detailed inspection of internal bottlenecks and hard-to-reach areas.
This capability supports a "Design for Depowdering" approach, a refinement of Design for Additive Manufacturing, which ensures that not only can a part be printed, but also that unfused powder can be reliably removed post-production. By evaluating depowderability during the design phase, manufacturers can modify channel dimensions, outlet positions, or component orientation to avoid issues discovered only after printing.
In addition to simulation, SPR-Pathfinder PRO provides production planning tools by estimating the time required for both the movement program calculation and the physical depowdering process. Process data can be recorded and transferred to higher-level production systems via OPC UA, supporting traceability and repeatability. A lower-cost alternative, SPR-Pathfinder BASIC, is also available for moderately complex parts, automating movement calculations without the advanced simulation features of the PRO version.
The release of SPR-Pathfinder PRO addresses a critical bottleneck in LPBF post-processing: efficient and complete powder removal from complex internal geometries. By enabling virtual testing and design iteration for depowdering, it aligns with the industry's push for robust, repeatable additive manufacturing processes, particularly for high-value applications like aerospace and medical devices where internal channel integrity is paramount.
