Use of Multi-Axis Magnetic fields in Orienting Material Property Enhancing Fibers, including for Strengthening and Joining purposes, in Additive Manufacturing Processes
20220388241 · 2022-12-08 ·

An apparatus and method to magnetically align fibers in a base additive material during an additive manufacturing process for material property enhancing purposes or to facilitate joining of multiple types of materials during the additive process to form an integrated part. The magnetically alignable fibers are positioned through the application of a controlled, multi-axis positioning magnetic field during the additive-material layer deposition phase. This allows the fibers to be embedded within the base additive-material in any three-dimensional desired orientation, and the orientation to be varied from layer to layer, to permit directional enhancement of material properties, dependent on the nature of the fiber materials themselves. Likewise, joining of multiple types of materials may be improved through the controlled deposition of such fibers embedded within the base material itself during the additive-process between layers of two or more dissimilar materials, to provide a directionally aligned mechanical attachment between layers of base additive materials to result in a strengthened consolidated part at the conclusion of the additive manufacturing process.

Apparatus and Method for Producing a Three-Dimensional Shaped Object
20220379556 · 2022-12-01 ·

The invention relates to an apparatus and to a method for producing a three-dimensional shaped object by means of material application in layers S.sub.n (n=1 to N), which has at least a material dispensing device, a drive device, a print substrate, a control device having a data memory, and a material removal device. In order to be able to recognize and eliminate defects in a layer S.sub.n, which can still occur later, i.e., after completion of this layer S.sub.n, it is proposed, according to the invention, to provide a monitoring device. Furthermore, a downstream evaluation device determines a layer S.sub.x in which the at least one defect was detected. Thereupon an error signal is generated and passed on to the control device. The material removal device completely removes the material of a partial region of the shaped object, from the layer S.sub.N that was last printed, down to the first of the defective layers S.sub.x. Building up the three-dimensional shaped object begins anew at the layer S.sub.x−1.

SHAPING APPARATUS AND SHAPING METHOD

A shaping apparatus includes an inkjet head forming one shaped layer by performing multiple main scans of ejecting an ink droplet of a curable ink that cures according to light of a predetermined wavelength toward a shaping table while reciprocating in a main scanning direction; a light source provided at least at one position on a front side in a forward or return direction in the main scan with respect to the inkjet head and irradiating an ink dot formed by the ink droplet with light; and a flattening unit flattening an upper surface of the ink dot. A shaped object is formed by layering the shaped layer. In the shaping apparatus, the ink dot is flatted by the flattening roller in the return movement without completely curing the ink dot by controlling the on/off state or illuminance of the light source during at least one of the main scans.
