Title:
A 3D PRINTER COMPRISING AN APPARATUS FOR POLYMER MATRIX COMPOSITES AND WORKING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/154775
Kind Code:
A3
Abstract:
The invention relates to an apparatus that can be mounted on a three-dimensional printer for the production of a short cut fiber-reinforced polymer composite with increased vertical strength between layers (3). The method of working of the three-dimensional printer comprising the said apparatus is also within the scope of the invention. The said method in its most general form comprises the steps of a. extruding at least two layers (3) by means of the extrusion nozzle (2), b. immersing and removing the needle (1a) or needles (1a) at least once and immersing it deeper than the thickness of the layer (3) by moving a module (1) comprising at least one needle (1a) that is longer than the thickness of the extruded final layer (3) and a flattener (1b) in one or more axes towards the layer (3), c. flattening the said layer (3) by means of the flattener (1b) in the module (1) after step b.
