Abstract:
In addition to working curves, other equally important, but previously not understood, relationships exist for both the green strength and the cured line width of ceramic-loaded resins. These characteristics of cured parts are strongly affected by the dose rate, a parameter usually controlled with laser power. Multiple smaller doses are used to produce a total integrated dose. Multiple exposures benefit from using high power to produce a fast process. However, since the dose for a given layer is broken into several smaller doses, the negative effect of high power on strength and cured linewidth is reduced.
