Single Pass Jetting (SPJ) works on the Production System and Shop System from Desktop Metal which is based on a new approach to metal 3D printing, where users can build metal parts in a matter of hours instead of weeks.
Single Pass Jetting works with full-width print bars containing over 32,000 jets that work together with powder spreaders to spread powder and print in a single quick pass across the build area, jetting millions of droplets per second to form high-resolution parts one layer at a time. Anti-sintering agents are then deposited, allowing the supports to easily fall off after the part is completed. Parts that have been safely printed in minutes instead of hours, are then sintered in the microwave-enhanced furnace.
With no tooling required, Single Pass Jetting is ideal for the production of complex, high-performance metal parts at high volumes or mid-volume production for the shop floor. Users can also gain major benefits of additive manufacturing like just-in-time production and mass customization at a lower cost, as compared to traditional manufacturing processes.
Open materials platform featuring high-quality MIM alloys with a mature supply chain and well-studied process controls,
Unlike powder bed fusion systems and alternative binder jetting technologies, Single Pass Jetting (SPJ) was designed specifically for compatibility with a wide range of materials, from stainless steels to precious metals.
Low-cost, low-flow metal powders from the MIM industry can be procured directly from suppliers and key process parameters can be adjusted manually to meet specific needs. This allows for greater quality control, as well as control over their supply chain.
