"Fundamentally, it comes down to a materials processing problem,” said Berrigan.

The lack of standardized production processes, quality assurance methods, significant material variability and reduced material performance are just some of the factors AFRL researchers need to overcome.

Depending on the application, material performance can be related to the strength of a part. For example, the electronic properties of an additive manufactured circuit may be worse than those of ones traditionally manufactured.

 
As additive manufacturing thinking evolved from being a way to develop prototypes to a method for actual production, the benefits and applications for the Air Force grew enormously, along with the potential for it to do even more. The manufacturing of customized parts and unique, complex geometric shapes at low production quantities can help maintain an aging aircraft fleet. Custom tools, engine components and light-weight parts can enable better maintenance and aircraft longevity.

“Additive manufacturing can address a multitude of challenges for us, and there is a big pull to implement these processes from the logistics community,” said Miller. “The fleet is aging, and replacement parts for planes built 30 years ago often no longer exist. Rapid production of a small number of hard-to-find parts is extremely valuable.”

However, the need to develop consistent, quality materials for additive manufacturing still remains a challenge that AFRL researchers are working diligently to address. Engineers need to have full confidence in additive manufactured part alternatives as they implement them as replacements in aging fleets or as system-level enablers in new weapon systems

SANTA FE, N.M., Aug. 25, 2017 (GLOBE NEWSWIRE) -- Sigma Labs, Inc. (NASDAQ:SGLB) (“Sigma Labs” or the “Company”), a provider of quality assurance software under the PrintRite3D® brand, today announced that the Company has received an invitation to speak at the Third Joint FAA – USAF Workshop on Qualification and Certification of Additively Manufactured Parts. Mark Cola, Sigma Labs’ President and CTO, will present, “In-situ Monitoring for Additive Manufacturing:  Implications for the Digital Manufacturing Age," at 2:30 p.m. Eastern Time, on Thursday, August 31, 2017 at the University of Dayton River Campus.

This is the third workshop jointly organized by the FAA and Air Force Research Laboratory (AFRL) on Qualification and Certification of Additively Manufactured Parts, building upon the objectives met in the second workshop held from August 30-September 1, 2016, which included providing additional training and reference material on additive manufacturing processes to FAA employees, benchmark qualification and certification considerations across the regulatory agencies, and promoting collaboration both across government/academia/industry and within the FAA regarding qualification and certification of additively manufactured parts. Last year’s workshop consisted of 33 presentations addressing background, past and present programs, and qualification/certification challenges regarding additively manufactured metal parts. The sustained, high interest in additive manufacturing and the importance of safe and robust qualification and certification procedures for aerospace parts were illustrated by the filled agenda and enthusiastic participation.

“We are delighted to participate in this crucially important workshop, which serves to reinforce the importance of qualification and certification of additive manufactured parts,” said Mark Cola, President and CTO of Sigma Labs. “Sigma is honored to be invited to participate and we look forward to contributing to the successful achievement of the workshop’s auspicious objectives.”
