Abstract
A method or apparatus for three-dimensionally printing. The method may comprise causing a phase change in a region of the first material by applying focused energy to the region using a focused energy source, and displacing the first material with a second material. The apparatus may comprise a container configured to hold a first material, a focused energy source configured to cause a phase change in a region of the first material by applying focused energy to the region, and an injector configured to displace the first material with a second material. The first material may comprise a yield stress material, which is a material exhibiting Herschel-Bulkley behavior. The yield stress material may comprise a soft granular gel. The second material may comprise one or more cells.
