Abstract
A three-dimensional fabrication apparatus includes a fabrication section, a liquid discharge unit, a housing, and a gas replacer. The fabrication section forms a powder layer with a fabrication material in a fabrication area. The liquid discharge unit discharges a fabrication liquid onto the powder layer to form a fabrication layer. The housing has an internal space accommodating at least one of the fabrication section or the liquid discharge unit. The gas replacer to generate and supply a laminar flow of a predetermined gas other than an air into the internal space of the housing to replace an ambient gas in the internal space from the air to the predetermined gas.
