Simufact Additive 2025.4 is confirmed as the latest version of this leading metal additive manufacturing simulation software. A primary source detailing this update reveals significant performance enhancements for large-scale Laser Powder Bed Fusion (L-PBF) simulations .

Here are the key features and improvements in Simufact Additive 2025.4:

 Major Performance Leap for Large Parts

This version focuses heavily on accelerating simulations for large, complex parts, directly addressing a key industry bottleneck.

  • Radically Faster Simulation: For large L-PBF models with 2 to 5 million or more voxel elements, simulation speed is increased by an average of 5 times . With optimized solver settings, this can reach up to 8 times faster than before .

  • New “Balanced Performance” Mode: A new default mode replaces the previous “FAST” option, offering a better trade-off between computational speed and simulation stability .

  • Smarter Parallel Processing: The default Domain Decomposition Method (DDM) has been upgraded. It now uses an inertia-driven partitioning strategy for better load balancing across processor cores and reduced communication overhead .

 Usability & Workflow Enhancements

Beyond raw performance, several updates make the software more robust and user-friendly.

  • Improved GUI Responsiveness: The graphical user interface (GUI) remains responsive even after running long, complex simulations .

  • Persistent Model Cuts: When you restart a simulation, any model cut definitions you previously set up are now fully retained, saving you from redoing work .

  • Smarter File Handling: Loading simulation工艺 files no longer creates redundant boundary conditions, keeping your simulation setups cleaner and more efficient .

 Core Simulation Capabilities

For context, Simufact Additive remains the industry standard for end-to-end process simulation. Its comprehensive capabilities include:

  • Process Simulation: Accurately predicts residual stress, distortion, and defects (like keyholing or lack of fusion) during the PBF process .

  • Distortion Compensation: Features advanced scan-based compensation that uses measured part data to automatically correct geometry deviations, exporting a compensated model for printing .

  • Multi-Process Workflow: Simulates the entire chain, including support generation, heat treatment, Hot Isostatic Pressing (HIP), and post-processing like wire EDM and machining .

  • Broader AM Support: Includes dedicated modules for simulating other metal AM processes like Binder Jetting .
