A surface texture modeling system for solid freeform fabrication
(Massachusetts Institute of Technology, 1997)
Solid Freeform Fabrication, SFF, is a set of manufacturing processes that fabricates parts as a bonded stack of individual layers. The Three Dimensional Printing process, 3DPTM process, is an SFF technology developed at ...
Effect of binder drop placement strategy on surface finish of fine ceramic parts by 3D printing
(Massachusetts Institute of Technology, 1998)
The interaction of droplets with powder is the key set of phenomena that determine many aspects of Three Dimensional Printing (3DP) including dimensional control and surface finish of the printed part. In the creation of ...
The design of a coiled tubing cutter for use in subsea oil drilling applications
(Massachusetts Institute of Technology, 1999)
A cutting device has been developed which can be used in conjunction with Schlumberger's SenTree product line to insure proper disconnect of an offshore system from a subsea wellhead during the testing of the well. Design ...
A three-dimensional printing machine to facilitate observation of printing phenomena
(Massachusetts Institute of Technology, 1998)
The understanding of binder-powder interaction during the Three Dimensional Printing process is critical to improving the characteristics of parts produced by this process. The ability to observe the binder-powder interaction ...
