Abstract: In example implementations, a method for extracting layers of build material into a carrier. The method includes providing a layer of build material onto a bed. Portions of the layer of build material on the bed are digitally printed with a liquid functional material (LFM). The method repeats providing the layer of build material and digitally printing without applying energy to the LFM to define a structure in layers of build material on the bed. The layers of build material are extracted into a carrier and the carrier is removed.

Abstract: A build module is provided. The build module may include a housing and a build material chamber in the housing to hold build material. The build module may include a build chamber in the housing. The build material chamber may be beneath the build chamber or next to the build chamber. The build chamber may include a moveable support member to receive successive layers of the build material from a build material distributor. The build module may be removably insertable into a build receiver of an additive manufacturing system to allow the additive manufacturing system to solidify a portion the successive layers to be received onto the movable support member.

Abstract: Methods and devices for setting a printing distance in a 3D printing system are disclosed. In one example the method comprises forming a layer of build material below a printing plane and relatively displacing the formed layer of build material with respect to the printing plane until the distance between the formed layer of build material and the printing plane is a desired printing distance.

Abstract: An apparatus for generating a three-dimensional object is provided. The apparatus may include a housing having a surface defining a build receiver to receive differently-sized build modules or to receive a plurality of build modules. The build modules may each include a build chamber to receive a layer of build material from a build material distributor. The apparatus may include an agent distributor to selectively deliver a coalescing agent onto portions of the layer of build material to be received from the build material distributor such that when energy is applied to the layer the portions of the layer coalesce and solidify to form a slice of the three-dimensional object.

Abstract: According to examples, a build module may include a housing, a build material chamber, and a build chamber. The build material chamber may be positioned beneath the build chamber in the housing and may include a moveable support member, in which a build material distributor is to supply successive layers of build material onto the moveable support member from the build material chamber. The build module may be removably insertable into a build receiver of an additive manufacturing system to allow the additive manufacturing system to solidify a portion of the successive layers received onto the moveable support member during the solidification process of the build material. The moveable support member may separate the build material chamber from the build chamber to block build material from the above the build material chamber from being received into the build material chamber during a solidification process of the build material.
