The RP-ML Goes Physical

The First In-Person Meeting, April 1999

The RP-ML (“Rapid Prototyping Mailing List”) is a group of several hundred fabber (digital fabricator) users and researchers around the world. The group is an electronic “mailing list,” which participates in a daily exchange of questions, information, ranting, and humor related to fabbers. For more information on this virtual fabber community, see’s RP-ML section.

While some of the RP-ML’s most active members know each other from various industry conferences, most participants are real-world strangers. In April 1999, the first official in-person meeting of RP-ML members was held in conjunction with the annual Rapid Prototyping & Manufacturing conference in Chicago.

The meeting was organized by Dr. Rafael Santillan of CIATEQ in Querétaro, Mexico and Prof. Elaine Hunt of Clemson University in Clemson, South Carolina. In addition, sponsorship of the room and refreshments was generously provided by Mark Littlewood of Time-Compression Technologies magazine and Mark Bliek of software developer Materialize.

The following photographs were taken by Dr. Santillan. Click on each image to enlarge.
