A 3D screen-printing apparatus for producing a shaped article includes: a printing table; a printing screen with a printing mask having a layer geometry for producing the shaped article layer by layer; an application unit to apply a printing material to the printing screen and to work it into the printing masks to produce a shaped-article layer; and a first positioning unit configured to increase the distance between the printing table and the printing screen by way of a first relative movement after the production of each shaped-article layer. The printing screen has printing masks, and the 3D screen-printing apparatus has a second positioning unit configured to perform a second relative movement between the printing table and the printing screen so different printing masks of the one printing screen can be positioned one after the other at a shaped-article position where an individual shaped article is to be built.

A 3D printing module, a build unit and a method are disclosed herein. The 3D printing module comprises a build unit receiving interface to receive a build unit. The build unit comprises a build platform with a build platform drive interface. The 3D printing module further comprises a driving mechanism engageable with the build platform drive interface to controllably move the build platform.

A 3D printing apparatus is disclosed herein. The 3D printing apparatus comprises a build compartment defining a build chamber within which a 3D object is to be generated; and a non-powered platform, moveable within the build chamber, comprising a platform drive interface to engage with an external drive mechanism to cause the platform to move. The 3D printing apparatus further comprises a powder compartment located laterally adjacent to the build compartment, within which build material is to be stored for use in the generation of the 3D object. The 3D printing apparatus also comprises a locking interface to couple the 3D printing apparatus with an external hosting device.

Methods and apparatus for forming three-dimensional objects by photo-curing a photo-curing liquid polymer exposed to a radiation in a space between a base transparent to the radiation and a supporting plate. The supporting plate moves progressively, in some cases continuously, away from said transparent base during the printing process, and that movement is characterized in that it is tilting, swinging, rotating, and/or swirling in three-dimensional space, based on the print geometry, in order to expedite printing speed and resin propagation throughout the build area. In one embodiment, the movement may resemble a spiral or helical path from the standpoint of points around its circumference.
