The Markforged Metal X printer is revolutionizing metal 3D printing by introducing a safer and more accessible approach. Unlike traditional metal 3D printers that involve hazardous loose powders and lasers, the Metal X utilizes a unique Bound Metal Deposition (BMD) process. This innovative technology prints metal powder encased in a plastic matrix, significantly mitigating safety concerns. This design allows for operation in standard shop environments with minimal need for specialized safety infrastructure, making 3d Print Metal technology more approachable than ever.
Functionally, the Metal X operates much like a highly sophisticated Fused Filament Fabrication (FFF) 3D printer. It boasts a precision-engineered gantry, a heated chamber and print bed, and advanced extrusion mechanisms. These features combine to ensure the reliable production of robust and durable metal parts. Furthermore, the Metal X is thoughtfully engineered for ease of maintenance, featuring readily accessible wear components and consumables such as print sheets, nozzles, and brushes, all designed for quick and simple replacement.
Complementing the Metal X, the Wash-1 is an essential solvent-based debinding system in the metal 3D printing process. It primarily uses Opteon SF-79, a high-performance and environmentally conscious fluid known for its superior cleaning efficacy and enhanced safety. For flexibility, Opteon SF-80 or Tergo Metal Cleaning Fluid can also be used if required. The Wash-1 is designed for straightforward operation with basic ventilation and provides a user-friendly experience, having been rigorously tested and confirmed as safe for shop environments.
The final stage in achieving 3D print metal parts involves sintering, carried out by the Markforged Sinter-2 and Sinter-1 furnaces. These tube furnaces are specifically optimized for sintering metal 3D printed components, delivering exceptional reliability and efficient cycle times, along with advanced safety functionalities. The Sinter-2 represents a more advanced option than the Sinter-1, offering a larger working volume, finer temperature control, and a mechanical door interlock for enhanced safety and precision. Standard sintering cycles for both the Sinter-1 and Sinter-2 typically range from 26 to 31 hours. However, the Sinter-2 also features an express mode capable of processing smaller batches of parts—up to 250g—in a reduced 17-hour timeframe, further enhancing the efficiency of 3D print metal manufacturing.
