Claim 0:
1. A method of removing debris from a liquid photopolymer in an additive fabrication device, the additive fabrication device comprising a container and a build platform and configured to form layers of solid material on the build platform by photocuring liquid photopolymer in the container, the method comprising:
forming a mesh of solid material adhered to an interior surface of the container by directing actinic radiation to the liquid photopolymer in the container, wherein the mesh of solid material is formed from a single layer of material and includes one or more features configured to assist in removal of the mesh of solid material from the container subsequent to fabrication of the mesh of solid material mesh; and
separating the mesh of solid material from the container at least in part by applying force to the one or more features, subsequent to one or more particles of debris within the liquid photopolymer becoming adhered to the mesh of solid material.
