Abstract
In one aspect, build materials for use with a three-dimensional (3D) printing system are described herein. In some embodiments, a build material described herein comprises an acrylate component, a photoinitiator component, a non-curable absorber component, and water. The photoinitiator component of the build material is operable to initiate curing of the acrylate component and/or other curable materials that may optionally be present when the photoinitiator is exposed to incident curing radiation having a Gaussian distribution of wavelengths and a peak wavelength λ. The build material has a penetration depth (D) and a critical energy (E) at the wavelength λ. In some embodiments, the Dis greater than 200 μm and less than 300 μm, and the Eis 3-12 mJ/cm. In other embodiments, the Dis greater than 10 μm and less than 50 μm, and the Eis 5-40 mJ/cm.
