Freeform fabrication of ionomeric polymer‐metal composite actuators

Evan Malone, Hod Lipson

To seek to produce low‐voltage, soft mechanical actuators entirely via freeform fabrication as part of a larger effort to freeform fabricate complete electromechanical devices…

Residual stresses in selective laser sintering and selective laser melting

Peter Mercelis, Jean‐Pierre Kruth

This paper presents an investigation into residual stresses in selective laser sintering (SLS) and selective laser melting (SLM), aiming at a better understanding of this…

Improving accuracy of powder‐based SFF processes by metal deposition from a nanoparticle dispersion

Nathan B. Crane, J. Wilkes, E. Sachs, Samuel M. Allen

Solid freeform fabrication processes such as three‐dimensional printing (3DP) and selective laser sintering (SLS) produce porous parts. Metal parts produced by these processes…

Development of SLS fuel cell current collectors

Ssuwei Chen, Jeremy Murphy, Jason Herlehy, David L. Bourell, Kristin L. Wood

This paper aims to present a new fabrication method for fuel cell current collectors. Demonstration of its usefulness and discussion of its impact on current collector design and…

Compensation zone approach to avoid print‐through errors in mask projection stereolithography builds

Ameya Shankar Limaye, David W. Rosen

Print‐through results in unwanted polymerization occurring beneath a part cured using Mask Projection Stereolithography (MPSLA) and thus creates errors in its vertical dimension…

Functionalizing stereolithography resins: effects of dispersed multi‐walled carbon nanotubes on physical properties

J. Hector Sandoval, Ryan B. Wicker

The present research investigates tailoring the physical properties of stereolithography (SL) epoxy‐based resins by dispersing controlled small amounts of multi‐walled carbon…

Case study: promoting design automation by rural manufacturers

Steve Tennyson, Gary McCain, Steve Hatten, Rudy Eggert

This paper describes a cooperative endeavor between a state university and a federal agency to modernize design automation among rural manufacturers. It concerns efforts to infuse…
