Sigma Labs is on the verge of a breakout once the orders come. The work with the Air Force and Aerojet to certify parts is HUGE!

The agreement is valued at $11.75 million over a three-year period, according to Jeffrey K. Smith, executive agent program manager for DPA Title 3, a Pentagon-wide initiative to develop affordable and commercially viable manufacturing capabilities for critical defense hardware. The government’s contribution to the demonstration is $6.3 million, the Air Force Research Laboratory said.

In a written response to questions, Smith said Aerojet Rocketdyne is expected to establish and demonstrate “a domestic production capability to manufacture large rocket engine parts using selective laser melting (SLM) technology that pass the key performance parameter criteria and quality requirements.”

As part of the contract Aerojet Rocketdyne will purchase and install SLM machines that will be used to build the components, Smith said. The company is expected to achieve that milestone during the second quarter of calendar year 2015, he said.

SLM is one of a number of additive manufacturing — also known as 3-D printing — techniques used to build hardware from 3-D designs using a layering process. The relatively new manufacturing process is being evaluated closely in the space industry as a way to bring down costs.

The SLM technique in particular uses a laser to melt, in selected areas, powdered metal that has been spread out on a flat bed. The process is repeated over and over on fresh new layers of metal powder until the desired object is created from the melted and fused material.

In a written response to questions, Jeff Haynes, additive manufacturing program manager at Sacramento, California-based Aerojet Rocketdyne, said the company will replicate parts of its operational RS-68 and RL-10 engines under the contract. The RS-68 is the main engine on United Launch Alliance’s Delta 4 rocket, which along with the company’s Atlas 5 launches most U.S. military and other government satellites. The RL-10 is an upper-stage engine, variants of which are used on both the Atlas 5 and Delta 4.

“These parts will demonstrate dimensional and structural capability to meet the demands of” the current traditionally manufactured parts, Haynes said. “Some parts will have improved performance characteristics which will be analytically measured based on the manufacturing approach applied.”

The process, Haynes said, will be evaluated for its ability to lower the cost of producing engines.

Haynes said the company will use government funds to procure the necessary machinery, and share in the cost of developing and demonstrating the additive manufacturing process for major engine components.

The program will require SLM manufacturing machines that are bigger than those that are widely available today, Aerojet Rocketdyne said in the press release.

Aerojet Rocketdyne visited leading SLM manufacturers in Germany in 2010 to evaluate the scaling potential of their machines, Haynes said. He said Aerojet Rocketdyne has already procured one scaled-up machine from Concept Laser GmbH and expects to take delivery in September. Plans call for buying two more from Concept Laser and one from EOS GmbH using funds from the latest Title 3 contract, he said.

Metal 3D printing specialist Sigma Labs Inc. has received an additional contract from Aerojet Rocketdyne, a California-based rocket and missile propulsion manufacturer. The new contract is a follow-on for a contract that was awarded to Sigma Labs last year to develop advanced quality control measures for 3D printing metal aerospace parts.



Sigma Labs is known for its PrintRite3D software, a proprietary program which allows users to rapidly and affordably certify and qualify metal aerospace parts that have been 3D printed. Last year, the company was awarded two significant contracts with Aerojet Rocketdyne: to help establish standards for qualifying metal 3D printed aerospace components, and to provide its technology to the America Makes 3D printing initiative.

Aerojet Rocketdyne, for its part, was awarded a massive $6 million contract from the U.S. Air Force in 2016 for the development of new standards for liquid-fueled rocket engines—part of the effort to move away from politically undesirable Russian-made aerospace parts, such as the RD-180 engines which are currently used on the Atlas V launch vehicle. Sigma Labs’ technology was evaluated for this massive project.



PrintRite3D, Sigma Labs

Sigma Labs’ new contract with Aerojet Rocketdyne will see the former upgrade its PrintRite3D software with new and more advanced sensors and algorithms. Additionally, under the new contract, Sigma Labs will offer engineering support through complex geometry-specific data analysis, and work together with Aerojet Rocketdyne to “assess and quantify” in-process data variation. At the moment, these are the only disclosed elements of the follow-on contract.
