Solukon’s Breakthrough in Large-Scale Metal Depowdering with SFM-AT1500-S
The journey through metal additive manufacturing innovation at Formnext 2024 would be incomplete without acknowledging the critical importance of post-processing. While printing the part is a significant step, efficiently and reliably preparing it for its intended application is equally vital, especially in metal powder bed fusion (PBF) technologies. The removal of unfused metal powder, known as depowdering, is a notoriously challenging process, particularly for large-scale and geometrically complex components with intricate internal structures. Solukon, a recognized global leader in automated depowdering systems, captured considerable attention with the launch of its largest metal depowdering solution, the SFM-AT1500-S. This impressive machine, officially announced just before Formnext, addresses a growing need within the industry for advanced automation in post-processing colossal metal parts. The SFM-AT1500-S is meticulously engineered to handle parts up to 1500 mm in size, utilizing patented Smart Powder Recuperation (SPR) technology. This system employs targeted vibration and rotation to thoroughly and automatically remove residual powder from internal channels and complex geometries, which is often impossible to achieve manually. The benefits are multifold: significantly reduced manual labor, enhanced operator safety by minimizing exposure to fine reactive metal powders, improved part quality and consistency, and optimized powder recovery for reuse, contributing to sustainability and cost-efficiency. Solukon’s SFM-AT1500-S stands as a testament to the industry’s commitment to industrializing every phase of the metal additive manufacturing workflow, making it more scalable, efficient, and robust for serial production.
AMFree: Pioneering XXL Metal 3D Printing with Robotic Flexibility
Continuing our exploration, we stopped at AMFree, a company that has garnered attention for its dedication to surmounting the inherent limitations of XXL metal 3D printing. Traditional metal additive manufacturing processes often face size constraints, leading to challenges in producing very large industrial components. AMFree specializes in innovative solutions that enable the creation of exceptionally large metal parts, opening doors to new applications across various heavy industries. At their booth, we had the compelling opportunity to witness a scaled-down version of the company’s sophisticated robotic arm system. This demonstration powerfully illustrated their approach to large-scale metal fabrication, which leverages the inherent flexibility, reach, and precision of industrial robotics. Unlike fixed-gantry systems, robotic arms offer unparalleled freedom of movement, making them ideal for directed energy deposition (DED) or similar processes tailored for large build volumes. A particularly striking exhibit was a substantial aluminum part that had been manufactured in an astonishingly short timeframe of just 13 hours. This rapid production capability for large-scale metal components is a game-changer, demonstrating AMFree’s potential to significantly reduce lead times and production costs for bespoke parts. Such innovation holds immense promise for sectors like aerospace, defense, maritime, and oil and gas, where the demand for large, custom, high-integrity metal components is paramount and where the combination of speed, material choice, and geometric freedom offered by AMFree’s technology can unlock new design possibilities and operational efficiencies.
