The mixing elements of these twin-screw extruders have complex lobes on the outside of the spline, which must be optimized for the material being extruded. Therefore, it is necessary to equip a unique mixing element for each different material. In traditional manufacturing, each of these components can be difficult to produce, often requiring advanced processing techniques, multiple processing settings, and custom fixtures. Adhesive jetting using a production system simplifies the manufacturing process, can print a large number of unique mixed elements in each build, and reduces production costs and delivery time compared with mechanical processing.

BOSTON--(BUSINESS WIRE)--Desktop Metal (NYSE: DM) today announced that it has qualified for 420 grade stainless steel (420 SS) used on the Production SystemTM platform, which uses The patent-pending Single Pass JettingTM (SPJ) technology is designed to achieve the fastest construction speed in the metal additive manufacturing industry. Manufacturers can now use SPJ technology to mass produce 420 SS high-strength end-use parts to meet demanding applications in the medical, aerospace, defense, and consumer goods industries.
420 SS is a kind of martensitic heat-treated stainless steel, which is characterized by high strength and hardness, and has corrosion resistance to the atmosphere, food, fresh water and weak acids when fully hardened. 420 SS is a common material that is widely used in various applications such as surgical and dental instruments, ball bearings, gear shafts, pump and valve components, fasteners, meters, hand tools, and high-end tableware.
"Engineers continue to look for metal additive manufacturing as the primary option for driving design and manufacturing innovation," said Jonah Myerberg, CTO and co-founder of Desktop Metal. "We believe that our certification of 420 SS and other high-strength alloys will accelerate the deployment of our AM 2.0 solutions to customers who wish to successfully mass-produce critical components."
420 stainless steel-main application
Desktop Metal's material science team has qualified and well-characterized 420 SS printing production system technology that meets the MPIF 35 standard for structural powder metallurgy parts set by the Metal Powder Industry Federation. Parts printed at 420 SS on the production system platform require no tools and minimize material waste. Compared with traditional manufacturing methods, production time and part costs are significantly reduced.
Examples of key applications include:
Robotic surgery systems for various medical procedures provide surgeons with a better range of motion, enhanced visibility, and precision that cannot be achieved with manual surgery. These systems have highly accurate motion systems and many complex small parts. The production system provides high-resolution adhesive jet printing, making it an ideal solution for realizing the fine features required by robotic surgical instruments. For parts such as locking hinge rods, 420 SS is an ideal material because of its high hardness and excellent corrosion resistance. Since the production of these parts using adhesive injection on the production system does not require any tools, mass production can be started after the design is completed, thereby saving valuable time and money, and a large amount of non-recurring costs for tool design and manufacturing.
Valve nozzle adapters connect nozzles to fluid systems in aerospace applications. In these applications, multiple versions of these adapters are often required to accommodate various nozzle geometries and sizes. Engineers prefer 420 SS for this type of adapter because of its excellent corrosion resistance and high hardness. With the ability to accommodate thousands of adapters in a single build, the production system can support the manufacture of these components in 420 SS, which is competitive with traditional manufacturing methods. In addition, without tools, multiple adapter geometries can be printed in one build, saving lead time and costs associated with tool replacement in traditional manufacturing processes.
Twin screw extruder mixing elements are used for mixing, compounding and processing viscous materials. These parts have complex lobes on the outside of the spline and must be optimized for the material being extruded. Therefore, each different material needs to be equipped with unique mixing elements. In traditional manufacturing, each of these components can be difficult to produce, often requiring advanced processing techniques, multiple processing settings, and custom fixtures. Adhesive jetting using a production system simplifies the manufacturing process, can print a large number of unique mixed elements in each build, and reduces production costs and delivery time compared with mechanical processing. 420 SS is an indispensable material in these applications because of its high hardness and corrosion resistance, which can ensure a long service life of the components and the hardness required for extrusion of various materials.
The world's fastest method for large-scale 3D printing of metal parts
The production system created by the inventor of adhesive jetting and single-pass inkjet technology is an industrial manufacturing platform supported by Desktop Metal's single-pass jetting technology. It aims to achieve up to 100 times the speed of traditional powder bed fusion additive manufacturing technology, and can produce up to millions of parts every year at a competitive cost compared with traditional mass production technology. The P-50 printer is paving the way for mass production of end-use parts—freeing up throughput, repeatability, and competitive parts costs.
