New Research Could Help Speed Up the 3D Printing Process

Binghamton University for R&D Magazine:  A team of researchers from Binghamton University, State University of New York and MIT have identified some bottlenecks in 3D printers, that, if improved, could speed up the entire process.

A research team led by Professor John Hart from the Department of Mechanical Engineering and Laboratory for Manufacturing and Productivity at the Massachusetts Institute of Technology, and including Binghamton Assistant Professor of Mechanical Engineering Scott Schiffres, found that many conventional desktop and professional AM systems build objects at about 10-20 cubic centimeters per hour when printing at a 0.2 millimeter thickness. One limitation of the system is a pinch-wheel mechanism used to feed building material. That wheel is limited in the force it can use (about 60 newtons) and the feed rate (about nine millimeters per second) in order to fully melt building material.

"We found that the rate at which a polymer melts is limiting in many implementations," said Schiffres. "The pressure required to push the polymer through the nozzle is a sharp function of temperature. If the core is not hot enough, the printer will not be able to squeeze the polymer through the nozzle."

"The work has implications for how to scale up additive manufacturing and the trade-off between higher-resolution printing and speed. We hope it will inspire future work to investigate pre-heating of the polymer, and printing with multiple extruders," added Schiffres.  Full Article:
