Abstract
According to some aspects, a mixer for detection and/or removal of material in an undesired location of an additive fabrication device is provided. For instance, in an inverse stereolithography device, liquid photopolymer may adhere and cure or partially cure to a surface of the additive fabrication device in a location that may interfere with the additive fabrication process and/or cause the additive fabrication process to be unsuccessful. The mixer may be coupled to a movable structure within the additive fabrication device so that the mixer, when coupled to the movable structure, may be moved along at least one axis within the additive fabrication device. The mixer may be configured to detect and/or remove undesired material from a surface within the additive fabrication device.
