Abstract

A method of forming an object by additive manufacturing within a furnace defining a cavity is provided. The method comprises: moving a build plate from a raised position to a lowered position within a cavity, the build plate for receiving build material to form an object thereon while moving from the raised position to the lowered position; and sintering the object within the furnace. The sintering comprises releasing heat from the cavity in the furnace by opening the upper lid. A furnace for additive manufacture of an object is further provided.
