Abstracts. Abstracts are due April 15. To submit an abstract, please click the "Conference Tools" button on the website homepage.
Poster Session. A poster session is set for late Tuesday afternoon. To participate, please submit an abstract and check off the poster button. Specific information respecting poster set-up may be found here.
Awards. The conference recognizes one outstanding junior and senior AM researcher annually. For more information on the Freeform and Additive Manufacturing Excellence (FAME) Awards, please see the Awards link. Plans are underway to publish "best papers" in special issues of the materials journal JOM and the on-line journal Virtual and Physical Prototyping. The number of papers is 8-10 for each journal. Papers will be selected from the reviewed manuscripts submitted to the SFF Symposium conference proceedings. Selected papers are subject to journal review, so publication is not guaranteed.
Manuscripts. Authors must present their work at the meeting to have their manuscript included in the proceedings. Manuscripts may be uploaded at this website. Please click the "Conference Tools" button on the website homepage. Authors submitting manuscripts have the option to have their manuscript reviewed/refereed. Having a conference proceedings article reviewed is important to some authors, particularly academicians. 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.
Weather. The weather in Austin is hot, temperatures averaging between a low of 70˚F (21˚C) and a high of 100˚F (38˚C). The average relative humidity is 50%. The probability of precipitation is virtually zero.
Suggested Dress. Dress for the meeting and evening special events is casual.
Language. The official language of the conference is English.
SFF Symposium Special Topics. Abstracts are specifically invited in four areas listed below. Abstracts 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.
Design Methodologies for Tailoring Performance of Additively Manufactured Parts for Naval Applications
Session Organizers, John Michopoulos, Naval Research Lab; Ajit Achuthan, Clarkson University; Amit Bagchi, Naval Research Laboratory
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.
Hybrid AM Processes
Session Organizer, Michael Sealy, University of Nebraska at Lincoln
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),
Laser re-processing (e.g., remelting or ablation)
Friction stir processing, etc.
Sensing and tool path planning in hybrid-AM
Dimensional accuracy and deviation from machining
Economic/Sustainability issues in hybrid-AM
Data Analytics in AM
Session Organizers, Prahalada Rao, University of Nebraska at Lincoln; Brian Giera, Lawrence Livermore National Laboratory
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.
Binder Jet Additive Manufacturing: materials, modeling, and experiments
Session Organizers: C. Fred Higgs III, Rice University; Zachary C. Cordero, Rice University
The reduced cost and build times associated with binder jet AM, among other advantages, have attracted recent interest from a multitude of industries that require complex and high-performance part production. However, much work remains to improve the mechanical properties of these components before they are widely adopted for end-use in aerospace, automotive, medical, and other demanding applications. Consequently, this session requests papers investigating the following topics related to binder jet AM:
Improving porosity, dimensional accuracy, surface roughness, and other performance properties
Optimization of input parameters in spreading, binding, sintering/infiltration, and post-processing stages
Physics-based modeling and experimental validation
Fluid-particle interaction between binder and powder
Shrinkage and distortion during sintering and/or liquid metal infiltration
New and exotic materials
Novel binder chemistries
Effects of environmental conditions on the process
