A mandrel is 3D-printed from a thermoplastic material that exhibits a glass transition. The mandrel has a mandrel wall made from the thermoplastic material and a cavity. The mandrel is coated with an elastomer coat and a fiber material is arranged on the elastomer coat. A composite part is formed from the fiber material by inserting the mandrel into a mold, pressurizing the mandrel, and heating the mold to a mold temperature greater than the glass transition temperature without melting the mandrel wall. The mandrel expands and presses the fiber material against the mold. The composite part is cured by increasing the mold temperature and simultaneously melting the mandrel wall.

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.
