Colorado-headquartered additive manufacturing materials developer Elementum 3D has introduced that it has been awarded patents within the U.S., Canada, and Australia for its Reactive Additive Manufacturing (RAM) expertise.
The RAM course of goals to increase the supplies library of additive manufacturing by enabling the 3D printing of beforehand unprintable supplies. With the additive manufacturing trade on the forefront of steel manufacturing, presenting advantageous purposes for a variety of key industries, the restricted number of printable steel supplies constrains wider adoption.
“Our revolutionary expertise advances metals improvement for additive manufacturing at an unprecedented tempo. It offers engineers the additional diploma of freedom they’ve by no means skilled, inspiring them to convey into existence new and progressive purposes,” explains Dr. Jacob Nuechterlein, President and Founder.

What’s Reactive Additive Manufacturing?
Based in 2014, Elementum 3D, previously referred to as Sinter Print, is an additive manufacturing analysis and improvement agency centered on the creation of superior metals, composites, and ceramics. These supplies are designed to fulfill the demand for high-durability, high-strength and light-weight options.
The corporate produces its supplies utilizing its patented RAM course of, which helps to forestall cracking in the course of the solidification course of. RAM expertise has allowed Elementum 3D to develop additive manufacturing powders for supplies which are normally tough to 3D print with utilizing Direct Steel Laser Sintering (DMLS) programs. Such supplies embrace high-performance alloy powders primarily based on established wrought alloys, together with aluminum 1000, 2024, 6061, 7050, and 7075.
Elementum 3D states that the brand new 3D printing supplies current superior properties in comparison with beforehand out there additive manufacturing supplies and corresponding wrought alloys. Excessive power wrought aluminum alloys utilized in a variety of industries couldn’t beforehand be 3D printed as a result of they endure scorching tearing (solidification cracking), resulting in elements with poor mechanical properties.
To fight this, the RAM course of kinds sub-micron inoculants within the soften pool that creates a nucleus round aluminum grains, producing a high quality, even microstructure for improved printability and efficiency. Elementum 3D hopes that, by fusing 3D printing with progressive new supplies and desirable-but-previously unprintable conventional manufacturing supplies, the potential purposes for additive manufacturing will increase.

Latest updates from Elementum 3D
The newly issued patents for the RAM course of is the most recent in a sequence of updates from the corporate. Final month, Elementum 3D introduced that it had achieved ISO 9001 certification for high quality administration. Issued by way of the administration certification agency Platinum Registration Inc, the certification contains the design and manufacture of superior metals, superalloys, and composites, along with manufacturing processes and prototype elements.
Earlier within the 12 months, the corporate additionally acquired an funding from Sumitomo Company of Americas (SCOA), the U.S. department of world buying and selling agency Sumitomo Company. Utilizing the funding, Elementum 3D will work in the direction of increasing the advertising and gross sales of its proprietary steel powder.
In 2019, the agency partnered with North Carolina-based hybrid manufacturing firm Keselowski Superior Manufacturing (KAM) to provide the corporate with superior supplies similar to its A6061- RAM2 powder. The powder is claimed to be akin to wrought 6061-T6 aluminum properties, a cloth that always faces difficulties when processed with additive manufacturing.
The nominations for the 2020 3D Printing Business Awards are actually open. Who do you suppose ought to make the shortlists for this 12 months’s present? Have your say now.
