Abstract
A method for providing safety protection in an additive manufacturing apparatus for forming a three-dimensional article through successive fusion of parts of a powder bed in an enclosable chamber, which parts corresponds to successive cross sections of the three-dimensional article is provided. The method comprising the steps of providing a position detecting device connected to a control unit to detect whether a foreign matter is within the enclosable chamber. The method may also include, upon detecting that the foreign matter is within the enclosable chamber, either (1) switching off, via the control unit, at least one device associated with the additive manufacturing apparatus; or (2) providing power to a powder suction device. Associated safety protection devices are also provided.
