Title:
SYSTEMS AND METHODS OF PRINTING WITH FIBER-REINFORCED MATERIALS
Document Type and Number:
WIPO Patent Application WO/2020/087048
Kind Code:
A3
Abstract:
In one aspect, the disclosure relates to a method of fabricating a three-dimensional object. The method includes transporting a first material, in a first state, the first material comprising a thermoplastic matrix and M reinforcing fibers, wherein the first material has a first cross-sectional profile; depositing, heating, and consolidating a segment of the first material such that it is placed in a second state having a second cross-sectional profile; and repeating the foregoing steps until a unitary composite object has been formed by M segments of the first material. In one embodiment, consolidation is performed to achieve a porosity of less than about 2%. In one embodiment, a ratio of volume of the reinforcing fibers to matrix first material ranges from about 0.5 to about 0.7.
