New Algorithm Cuts 3D Printing Times by Half

The solution is specifically applicable to desktop fused
deposition modelling (FDM) machines. As the print head of a 3D
printer deposits layers of molten plastic, its moving parts
cause vibrations. This can lead to errors when fabricating an
object; the faster a print head moves, the more the machine
vibrates and the greater the chances of a printing error.
"Armed with knowledge of the printer's dynamic behavior, the
program anticipates when the printer may vibrate excessively
and adjusts its motions accordingly," says Chinedum Okwudire,
an associate professor of mechanical engineering who directs
the University's Smart and Sustainable Automation Research
Lab. The findings were published in the academic journal
Mechatronics in a paper titled: "A limited-preview filtered
B-spline approach to tracking control - With application to
vibration-induced error compensation of a 3D printer." The
consumer printers used in the research were a HICTOP Prusa i3
and a LulzBot Taz 6.
