    摘要： An example of a build unit is disclosed. The build unit comprises a build chamber defining an open-topped object generation volume having a uniform cross-section. The build unit also comprises a build platform to move vertically within the object generation volume. The build unit is to fixably receive a cover plate to reduce the cross-section of an opening of the build chamber and to receive a compressible element to be placed between the cover plate and the build platform to reduce the object generation volume.

    摘要： An example of an additive manufacturing apparatus is disclosed. The apparatus comprises a process module to selectively treat a layer of build material from a build chamber formed from at least one sidewall and comprising a build platform moveable within the build chamber. The apparatus also comprises a powder distribution module to form a layer of build material in the build chamber. The apparatus further comprises a controller to receive data corresponding to an object to be generated and control the powder distribution module to form successive layers of build material on the build platform. The controller is further to control the process module to selectively treat portions of the formed layers to generate the object based on the received data and to generate the barrier based on the defined data.

    摘要： According to one example there is provided a method for three-dimensional printing. The method comprises forming a pile of build material on a heatable plate adjacent a spreader, heating the pile of build material by contact with the heatable plate, and spreading the heated pile of build material on a support platform.
