Methods and systems for layered deposition modelling with reinforced interlayer connections

摘要

A method for providing reinforced interlayer connections during layered deposition modelling is provided. The method comprises the steps of a) depositing a plurality of layers (1, 2) of extrudable material with an extruder head comprising a layer engagement member (3); b) positioning the extruder head at an x-y location above the plurality of layers (1, 2) where interlayer connection between the plurality of layers (1, 2) is to be reinforced; c) lowering the layer engagement member (3) for engagement with the plurality of layers (1, 2), thereby locally fusing the plurality of layers (1, 2) at the x-y location; and d) raising the layer engagement member (3) from the plurality of layers (1, 2).
