Claim 0:
1. A method for manufacturing an object by additive manufacturing layer by layer in a layer sequence, the method performed by an apparatus, wherein the method comprises the step of:
adjusting, by a control unit of the apparatus, for individual layers in the layer sequence, a setting of at least one process parameter, during the manufacture of the object, wherein the at least one process parameter is chosen from the group consisting of:
a temperature of a gas present in a process chamber of the apparatus;
a flow rate and/or a flow speed of the gas present in the process chamber;
a relative humidity of the gas present in the process chamber;
a pressure in the process chamber;
an oxygen level in the process chamber;
a flow of the gas through the process chamber;
a temperature of a bath of powdered material provided in the process chamber;
a temperature of a build plate supporting the layer sequence at a lower side thereof;
a speed at which a surface level of an individual layer in the layer sequence is leveled;
a number of swipes for supplying an individual layer in the layer sequence;
a quantity of powdered material used for providing an individual layer in the layer sequence;
a number of successive layers after which a powdered material reservoir of the apparatus needs to be refilled with powdered material;
an extraction rate of extracting a mixture of the gas and waste particles from the process chamber;
a filtering rate of filtering the mixture of the gas and waste particles from the process chamber; and
an alignment accuracy of solidifying powdered material at the surface level for manufacturing the object.
