Method and apparatus for producing an object by means of additive manufacturing

A method for producing an object by additive manufacturing, the method comprising the steps of:

• receiving, in a process chamber, a bath of material, wherein a surface level of the bath of material defines an object working area;
• solidifying, by a solidifying device, a selective layer-part of the material on the surface level;
• and
• controlled oxidization, of waste particles originating from the solidifying of the material, by controlling an oxygen level, such that oxidized waste particles are obtained and ignition of the waste particles is avoided.

An apparatus for producing an object by additive manufacturing, comprising:

• a process chamber for receiving a bath of material, wherein a surface level of the bath of material defines an object working area;
• a solidifying device for solidifying a selective layer-part of the material on the surface level;
• and
• an oxidization device configured for controlled oxidization of waste particles originating from the solidifying of the material, by controlling an oxygen level, in use, such that oxidized waste particles are obtained and ignition of the waste particles is avoided.
