Abstract
Additive Manufacturing (AM), popularly called “3D printing,” has
benefited from many two-dimensional (2D) printing technology
developments, but has yet to fully exploit the potential of digital
printing techniques.
The very essence of AM is accurately forming individual layers and
laminating them together. One of the best commercially proven
methods for forming complex powder layers is laser printing, which
has yet to be used to directly print three-dimensional (3D) objects
above the microscale, despite significant endeavour.
The core discovery of this PhD is that the electrostatic charge on
toner particles, which enables the digital material patterning
capabilities of 2D laser printing/photocopying, is disabling for
building defect-free 3D objects after the manner attempted to
date. Toner charge is not mostly neutralized with fusing as
previously assumed.
This work characterizes and substantiates the accumulation of
residual toner charge as a primary cause for defects arising in 3D
printed bodies. Next, various means are assessed to manage and
neutralize residual toner charge. Finally, the complementary
implementation of charge neutralization with electrostatic transfer
methods is explored.
