This Proceedings of the Sixth Solid Freeform Fabrication (SFF) Symposium, held at The
University of Texas in Austin on August 7-9, 1995, was attended by over 150 national and
international researchers. Papers addressed SFF issues in computer software, machine design,
materials synthesis and processing, and integrated manufacturing. The continued growth in the
research, application and development of SFF approaches was readily apparent from the increased
participation over previous years and the diverse domestic and foreign attendees from industrial
users, SFF machine manufacturers, universities, and government. The excitement generated at the
Symposium reflects the participants' total involvement in SFF and the future technical health of this
growing technology. The Symposium organizers look forward to its being a continuing forum for
technical exchange among the expanding body of researchers involved in SFF.
The Symposium was again organized in a manner to allow the multi-disciplinary nature of
the SFF research to be presented coherently, with various sessions emphasizing computer issues,
machine topics, and the variety of materials aspects of SFF. To avoid parallel sessions, a poster
session was organized. We believe that documenting the constantly changing state of SFF art as
represented by these Proceedings will serve both the people presently involved in this fruitful area
as well as the large flux of new researchers and users entering the field.
Several important issues surfaced during a plenary discussion at the end of the meeting.
Considerable interest was expressed in the availability of related topics on the worldwide web. In
response, The University of Texas at Austin Laboratory for Freeform Fabrication homepage
(http://shimano.me.utexas.edu/sffl) now includes links to all sites currently published by our home
page, including all locations submitted at the meeting. This current list of web locations is also
included at the end of this proceedings volume. We will be pleased to update the list by notification
of one of the Symposium Proceedings editors.
Another issue which would benefit a majority of SFF researchers is formation of a research
infrastructure manufacturing network. Interest was expressed in the formation of a library of
"public domain" .STL files. Clemson University has created this, and Elaine Persall is the contact
person. contact information is in the participant index.
The editors would like to extend a warm "Thank You" to Sue Ferentinos for her detailed
handling of the logistics of the meeting and the Proceedings, as well as her excellent performance
as registrar and problem solver during the meeting. We also acknowledge the support efforts of
Vicki Lehmeier and Cindy Pflughoft throughout. We would like to thank the organizing
committee, the session chairmen, the attendees for their enthusiastic contributions, and the speakers
both for their significant contribution to the meeting and for the relatively prompt delivery of the
manuscripts comprising this volume. We look forward to the continued close cooperation of the
SFF community in organizing the Symposium. We also want to thank ONR through Grant No.
N00014-95-1-0424, ARPA, and The Minerals, Metals and Materials Society for co-sponsoring the
Symposium with the Mechanical Engineering Department and the Center for Materials Science and
Engineering at the University of Texas at Austin.
