JANNAF AMP Additive Manufacturing for Propulsion Applications TIM Session Areas

The TIM will cover systems development within the ten session areas described below. Additional information concerning these areas or the topics being solicited should be directed to the respective Area Chair.

TIM Session Areas

Areas of interest included in the Call for Presentations are:

Session Area I: Component Fabrication and Test

Adam Naramore, Orbital ATK
Telephone: (410) 392-1755
Email: Adam.Naramore@OrbitalATK.com

This session area will discuss various programs and projects where unique components were built to either reduce time and cost, or to produce a novel component that could not have been produced using alternative manufacturing processes. Components that were taken through fabrication and into a test program are desired, although new and innovative parts that were only taken through manufacturing are also encouraged.

Session Area II: Additive Manufacturing Techniques and Machines

Jamie Malak, Air Force Research Laboratory
Telephone: (661) 275-5539
Email: Jamie.Malak@us.af.mil

This area focuses on exploring different additive manufacturing techniques currently in use or in development. Emphasis should be on advancing the state of the art, exploring new, larger builds, innovative techniques, and machines that can achieve component builds with more robust material properties compared to traditional machines.

Session Area III: Post Build Processing, Finishing, and Inspection

Karen Taminger, NASA LARC
Telephone: (757) 864-3131
Email: Karen.M.Taminger@nasa.gov

After components are built using additive manufacturing techniques, sometimes post build processing is required. This forum will discuss the various post build processing and finishing techniques. This can include (but is not limited to) heat treatment, stress relief, slurry honing, surface finishing, drilling, milling and welding.
One common issue with additive manufactured components is the ability to inspect the components, particularly those with complex internal geometries. While an advantage of additive manufacturing is being able to combine several parts that were once welded together, now new challenges present themselves in terms of inspection of critical features that are not easily accessed. Presentations on post build finishing and inspection techniques and challenges are encouraged.

Session Area IV: Materials

Dr. David L. Ellis, NASA GRC
Telephone: (216) 433-8736
Email: David.L.Ellis@nasa.gov

Material development is critical for the success of additive manufacturing. This session will discuss materials that have been used with additive manufacturing, new materials, gradient materials, and powder certification.

Session Area V: Design for Additive Manufacturing

Elizabeth Robertson, NASA MSFC
Telephone: (256) 544-9692
Email: elizabeth.robertson@nasa.gov

The design methodology for additive manufacturing can radically differ from other manufacturing processes due to the highly controlled nature of the part production and the ability to create shapes unachievable with conventional manufacturing.  For example, a part can be optimized for weight by removing all unnecessary material while remaining structurally sound.  Optimizing designs to take full advantage of the machines’ capabilities, while developing optimized orientations, supports and other structures for manufacturing, is a key issues that can affect economical part production.  Designing to minimize time for production and lower manufacturing costs is also a challenge.  This session seeks to address these and related issues of integrating the part design process with additive manufacturing’s new capabilities.

Session Area VI: Modeling and Simulation

Dr. Phillip A. Farrington, University of Alabama in Huntsville
Telephone: (256) 824-6568
Email: farrinp@uah.edu

The presentations in this session focus on modeling and simulation of additive manufacturing processes. Potential topics include: Simulation of AM processes to predict residual stresses, microstructure, and/or surface topology; Modeling of AM processes to consider the resultant effect of print direction, part orientation, and/or power level; Modeling and simulation of support structures; And, the use of modeling and simulation for process and part certification and qualification; As well as other related topics. 

Session Area VII: Process Qualification and Specifications

Kristin Morgan, NASA MSFC
Telephone: (256) 544-1025
Email: kristin.l.morgan@nasa.gov

This session will explore the state of additive manufacturing (AM) qualification and certification processes for propulsion applications.  AM approaches can offer benefits to reduce lead times and costs and to introduce new approaches to design and manufacturing.  Much development progress has been made in the areas of materials and processes, while significant challenges still remain, especially with respect to quality and inspection and the qualification and certification processes. These processes are the key to ensuring that new and innovative technologies, such as AM, meet requirements for flight hardware.  Presenters will highlight the accomplishments and challenges in developing, applying, and certifying AM technologies from the materials, processes, and quality control perspectives. 

Session Area VIII: Process Analysis, Sensing, and Control, Non-Destructive Evaluation

Darrell Gaddy, NASA MSFC
Telephone: (256) 544-0198
Email: darrell.e.gaddy@nasa.gov

This session area addresses work that is being performed to assess additive manufacturing processes, including in-process sensing and controls (e.g. Infrared thermography). Also included is the thermal and/or structural modeling of the processes. Non-destructive evaluations (during the build) are also encouraged.

Session Area IX: Special Topics

Alison Park, Aerojet Rocketdyne
Telephone: (661) 313-7691
Email: Alison.Park@rocket.com

This session is seeking topics not covered by the other AM sessions. This could include work in multi-material AM, hybrid systems which integrates AM and CNC machining and welding for example. The purpose of this session is to look at AM concept expanders.

Session Area X: Future Needs

John Vickers, NASA MSFC
Telephone: (256) 544-3581
Email: john.h.vickers@nasa.gov

The session presentations will be a combination of invited presentations and abstracts selected from industry, government, and academia. We are seeking presentations that project beyond the current state-of-the-art technologies and research advancements  of additive manufacturing in focus areas including: design, materials (e.g. materials science, composites, multi-functional), next-generation processes/equipment, integrated modeling/digital twin/physics based/analysis, NDE/inspection/testing, and sensors/controls.
