AM PravaH® advances LPBF simulations, and the upcoming AM PravaH 2.0 brings unmatched precision and efficiency to AM processes.
Additive manufacturing (AM) is a transformative technology, that redefines how industries approach production and design. Its ability to fabricate intricate geometries and optimize material usage has unlocked possibilities that were once beyond reach. Yet, these breakthroughs come with challenges, as AM processes involve highly dynamic and complex phenomena such as thermal gradients, material flow, and microstructural changes. Addressing these intricacies requires robust simulation platforms. Paanduv Applications, known for its expertise in computational physics, has developed AM PravaH®, a simulation software that has been widely adopted by leading organizations and research institutions worldwide. The current version of AM PravaH specializes in the Laser Powder Bed Fusion (LPBF) process, offering detailed modeling capabilities that optimize part quality, and process efficiency and reduce the cycle time. Building on this foundation, Paanduv will now soon be launching its latest iteration, AM PravaH 2.0, introducing advanced features to tackle even broader challenges in AM with unparalleled precision.
One of the key updates in AM PravaH 2.0 is the inclusion of Wire Laser Additive Manufacturing (WLAM) simulation capabilities. WLAM is known for its ability to produce large-scale metal components with high material efficiency and minimal waste, making it ideal for industries like aerospace and energy.
AM PravaH 2.0 introduces advanced WLAM simulations that allow users to model complex multi-track and multi-layer builds. These simulations account for intricate physical interactions such as thermal gradients, material flow dynamics, and layer fusion quality. The software provides predictive insights into potential defects like lack of fusion or porosity, enabling users to optimize build parameters effectively.
An updated graphical user interface (GUI) further streamlines this process, offering an intuitive platform to analyze the influence of various parameters, including laser power, wire feed rate, and scan strategies. By simulating scenarios such as thermal accumulation in multi-layer tracks, engineers can better design components like turbine blades or lightweight structures with enhanced precision and reliability.
The additive manufacturing market is expected to reach USD 74.70 billion, growing at a CAGR of 20.6% from 2023 to 2030. Tools like AM PravaH 2.0 are pivotal in addressing the increasing demand for robust and scalable manufacturing solutions.
Key Features for Improved Simulations:
Temperature-Dependent Material Properties: Material behavior influenced by temperature variations can now be seamlessly integrated into simulations. This general capability enables precise predictions of melt pool dynamics and phase transitions, critical for both LPBF and WLAM processes where thermal management is key.
Laser Beam Shaping: Simulating laser intensity profiles, such as Gaussian, elliptical, or custom distributions, allows enhanced control over heat input and material processing. This feature is equally applicable to LPBF and WLAM processes, optimizing energy efficiency and the quality of builds.
Simulation Queue Management: A user-friendly workflow that lets engineers configure multiple simulations to run consecutively, streamlining iterative designs and sensitivity analyses across manufacturing processes.
Non-Spherical Powder Particles: This feature, specific to LPBF, models real-world particle geometries, improving accuracy in simulations related to packing density, flowability, and heat absorption.
AM PravaH 2.0 aims to support industries that require precision and efficiency in metal additive manufacturing. The WLAM module, for instance, provides tools for analyzing layer-by-layer construction, which is critical in sectors like aerospace for achieving lightweight and durable components. Similarly, the energy sector benefits from WLAM’s precision in fabricating high-performance parts such as turbine blades.
Preliminary use of AM PravaH’s earlier versions has significantly improved manufacturing outcomes. Esteemed organizations and research labs globally, including India’s Defence organization, have adopted this software to enhance the quality of LPBF parts.
By introducing these features, AM PravaH 2.0 offers a platform for more accurate and efficient simulations, catering to the growing demands of additive manufacturing processes. These tools help engineers and researchers improve design accuracy, reduce waste, and address practical manufacturing challenges. As AM technologies continue to develop, simulation software like AM PravaH 2.0 plays a crucial role in bridging the gap between concept and production.
