Abstract: A method for generating improved machine control data. Event series is generated from input machine control data that is linked with a mesh data that is also generated from the input machine control data. Thus, an activation time (t_act) is determined which indicates the point in time at which the additive manufacturing machine prints a portion of the object that is represented by that mesh element. A full 3D-thermal simulation is run on the mesh elements. Each time the element temperature (T_el) exceeds a predetermined threshold, the activation time (t_act) is increased by a predetermined time increment and the event series is updated. Finally the event series is converted back to output machine control data.

Abstract: A 3D printing device includes a printing substrate, a movable printing head configured for additively producing from a modelling material a component on the printing substrate, and a flexible printing space cover which, proceeding from the printing head, spans the printing substrate such that a closed printing space is formed between the printing head and the printing substrate, wherein a printing nozzle of the printing head for applying the modelling material protrudes into the printing space. A support structure of the device includes flexible support rods which run from the printing head to the printing substrate and which hold the printing space cover above the printing substrate.
