Each manuscript receives two reviews using a referee pool composed of all authors submitting reviewed manuscripts. Authors selecting reviewed status for their manuscript must review two other manuscripts.  Reviews are due at the conference; final manuscripts are due August 31.

 

Proceedings

 

Papers presented in presentation and poster sessions will be published in flash-drive and swing-hinge bound formats.  Each person (including students) registering for the full meeting will receive a copy in flash-drive format ~4 months after the meeting.  Swing-hinge copies are available for purchase.  Proceedings papers will be accessible and downloadable on line at the SFF Symposium website at no charge.

Internet Service. The Hilton Hotel is providing complimentary in-room internet service for attendees making reservations on the conference block of rooms.  Complimentary wireless internet is available on the meeting floors at the conference space.

SFF Symposium Special Sessions 

 

Authors are encouraged to submit abstracts in any topic related to Additive Manufacturing.  During the abstract submission process, authors will have an opportunity to self select from approximately 15 difference topic areas.  We have 6 "special session topics" being organized by parties external to the Organizing Committee.  Abstracts for special topic inclusion should be submitted using the usual on-line submission process, but, during abstract submission, authors should select the special session topic in the "Select the Topical Area" feature.

Special Session: Data Analytics in AM
Prahalada Rao, University of Nebraska at Lincoln, rao@unl.edu
Scope: There is a burgeoning need to integrate in-process sensing and data analytics to overcome the process repeatability and part quality-related challenges in Additive Manufacturing (AM). These research thrusts are rooted in the analysis of high volume, variety and velocity of data with concomitant challenges from the domain of Big Data analytics. Accordingly, this special SFF session on Data Analytics in AM seeks papers in the following broadly defined areas:
Sensor fusion and data analytics for In-process quality assurance
Online process monitoring and defect mitigation
Sensor-based process-machine interaction modeling
Post-process data-driven, non-destructive metrology and measurement.

 

 Special Session: Design Methodologies for Tailoring Performance of Additively Manufactured Parts for Naval Applications
John Michopoulos, Naval Research Lab
CONTACT: Ajit Achuthan, Clarkson University, aachutha@clarkson.edu
Amit Bagchi, Naval Research Laboratory
Scope: AM technologies have alleviated many of the limitations of conventional manufacturing technologies while raising many new issues of concerns to address. Both the widening of the design space and the morphological characteristics introduced by the AM processes (i.e, porosity, grain morphology variability, cellular substructures, surface roughness, etc.) cannot be addressed by conventional design principles. Although the topological and morphological design and optimization for AM materials and structures have gained a lot of attention, harnessing the full potential of AM to tailor the intended performance by systematically utilizing this large design space calls for the development of radically new design methodologies. In this session, we invite presentations/papers pertaining to experimental/modeling studies primarily focused on leveraging the benefits of AM for novel designs in a way that demonstrates unified approaches integrating morphological, topological, structural and functional designs. The topics to be covered in this session include: 1) development of new design methodologies, 2) hierarchical design of microstructure (cellular features, phases, grain sizes, shapes and texture); 3) structurally graded design of parts (reactive materials, heat exchangers, etc.); 4) mesostructural design; 5) multi-material design and manufacturing. Although a major emphasis of this special session will be on studies related to Naval Applications, general studies that serve the broader interests of Navy are also encouraged.

 

Special Session: Dimensional and Surface Characterization for Additive Manufacturing
CONTACT: Jason Fox, National Institute of Standards and Technology, jason.fox@nist.gov
Joy Gockel, Wright State University
Scope: For the adoption of AM to continue to accelerate, a strong understanding of the dimensional and surface characteristics of AM parts will be required. As designers and engineers continue to push the limits of complexity, users must be able to determine accuracy of fabrication and finishing techniques. With this in mind, the purpose of this symposium is to review and discuss the measurement and characterization of AM part surfaces and dimensions. Emphasis of the talks should be on the measurement and characterization methods and uncertainty. Suitable topics for this symposium include:
Dimensional accuracy and surface finish of AM technologies
Dimensional characterization of internal geometries using XCT
Designation and realization of product definitions for AM (see ASME Y14.46 Product Definition for Additive Manufacturing)
Dimensional and surface characterization for complex geometries
Use of surface and dimensional characterization as a process signature of AM equipment
Characterization of as-built and post-processed AM surfaces
Relationships of dimensional and surface characteristics to function

 

Special Session: Hybrid AM Processes
Michael Sealy, University of Nebraska at Lincoln, sealy@unl.edu
Scope: This is the third year for a special session on hybrid additive manufacturing (hybrid-AM). Participants are invited to present research on hybrid additive manufacturing (hybrid-AM) processes. Hybrid AM processes incorporate additive manufacturing with one or more secondary processes and/or energy sources that are fully coupled and synergistically affect part quality, functionality, and/or process performance. Potential topics of interest include but are not limited to AM processes coupled with:
Machining (e.g., milling), 
Rolling
Laser re-processing (e.g., remelting or ablation)
Surface treatments
Friction stir processing, etc.
Hybrid-AM machines
Sensing and tool path planning in hybrid-AM
Dimensional accuracy and deviation from machining 
Economic/Sustainability issues in hybrid-AM

 

Special Session: Solid Particle Aerosol Deposition Processes
Desiderio Kovar, University of Texas at Austin, dkovar@mail.utexas.edu
Scope: Solid particle aerosol deposition (AKA micro cold spray) offers a means to deposit patterned or large area ceramic and metal films at room temperature onto polymer, metal, or ceramic substrates. These unique capabilities offer the possibilities to direct-write a wide range of technologically significant materials and devices. The ability to tailor film microstructure and properties requires a further understanding of the roles of particle properties and processing parameters on film properties.  This symposium seeks papers on the study of the physics-based modeling of process parameters, particle and film and pattern morphologies, films properties, and materials and device development.

 

Special Session: Wire-fed AM Processes
Andrzej Nycz, ORNL-MDF
CONTACT: Bishal Silwal, Georgia Southern University, bsilwal@georgiasouthern.edu
Bill Hamel, University of Tennessee
Chris Allison, GKN aerospace
Scope: Wire-fed metal AM has significant potential to revolutionize the way large-scale parts are fabricated. The objective of this special session is to accelerate and disseminate research activity in wire-fed AM. All types of power sources including laser, welding arc and electron beam will be considered. Participants are invited to present research and development in wire-fed additive manufacturing related to process development (hardware and software), tool path planning, new material deposition, numerical simulation, multi-wire deposition, surface features and many more. All research areas of wire-fed AM will be considered in this special session.
