Desktop Metal qualified commercially pure copper (> 99.95% purity) for additive manufacturing on the production system platform, which relies on patent-pending Single Pass Jetting (SPJ) technology designed to achieve the fastest manufacturing speeds of any powder bed metal additive manufacturing. . Customers can now take advantage of SPJ technology for large scale high performance copper part production in a wide variety of industries including automotive, aerospace and electronics.

With its thermal and electrical conductivity, commercially pure copper is an ideal material for applications requiring heat or electricity transfer, such as cold plates, washers and manifolds, heat sinks, heat exchangers and heat exchangers. bus bars used in energy intensive electrical applications. It is the third most consumed industrial metal in the world.

“Copper is a material in high demand by many of our customers and prospects, and has applications spanning a wide variety of industries, from thermal material found in air and liquid cooling systems to conformally cooled coils for transmitting high frequency currents, ”said Jonah Myerberg, co-founder and CTO of Desktop Metal. “We are excited to be able to expand our extensive portfolio of production system materials to help customers looking to 3D print electrically and thermally conductive components on a large scale and at a fraction of the cost of conventional manufacturing methods. “

Desktop Metal’s material science team qualified and fully characterized commercially pure copper (C10300) printed on the production system technology with a purity greater than 99.95%, allowing excellent thermal and electrical conductivity. Manufacturers can now print copper parts on the production system with significant geometric complexity in a single step instead of brazing multiple conventionally produced copper components together, eliminating a time-consuming and costly process prone to error and waste . With the geometric freedom afforded by the binder jet, engineers can also explore new high-performance designs not possible with conventional manufacturing methods, such as truss structures and conformal cooling channels to improve heat transfer.

Liquid cooling plates are used to regulate temperature on high performance microprocessors. The coolant flows through the fins, which provide a large area for transferring heat from the fluid passing to the heat sink in order to cool the chip which is attached to the outer body. These cooling geometries typically require capital-intensive, long-lead-time, and skilled labor-intensive production processes, such as beveling and machining, given the challenges associated with precision and machining. repeatability in such a small form factor. In addition, these commonly used conventional manufacturing processes are subtractive and produce excess waste, dramatically increasing the costs of associated parts.

While conventional production methods for this liquid cooling plate required the machining and assembly of several separate components due to tool access restrictions, the binder jet on the production system can produce the part as as a single component, reducing manufacturing and operating complexity, part cost and delivery time. . The production system frees up the capacity to print hundreds of cooling plates per day, enabling cost-effective volume production. Copper is the ideal material for heat exchangers due to its excellent conductivity, maximizing heat dissipation from the microchip to the coolant.

<p>Created by the inventors of single-pass binderjet and inkjet technology, the production system is an industrial manufacturing platform powered by Desktop Metal’s SPJ technology.  It is designed to achieve speeds up to 100 times faster than traditional powder bed fusion additive manufacturing technologies and enable production quantities of up to millions of parts per year at competitive costs compared to conventional mass production techniques.</p>
<p>The production system platform consists of two printer models: the P-1, a solution for process development and mass production applications, and the P-50, a mass production solution to large form factor for end-use parts.  The production system combines Desktop Metal engineered binders with an open materials platform, allowing customers to produce high performance parts using the same low cost metal powders used in the metal injection molding industry. (MIM).  An inert processing environment allows compatibility with a variety of materials, including high performance alloys and even reactive metals, such as aluminum and titanium.</p>
<p>In addition to copper, the production system platform material library has expanded to include D2 tool steel, 420 stainless steel, IN625 nickel alloy, 4140 low alloy steel , 316L stainless steel and 17-4PH stainless steel, each qualified by Desktop Metal.  The platform also supports several materials qualified by customers, including silver and gold, and Desktop Metal plans to add additional metals to its portfolio, including tool steels, stainless steels, superalloys. , etc.</p>
