Abstract
A fiber-reinforced resin strand used as a manufacturing material for a 3D printer, the fiber-reinforced resin strand containing: a base material containing a thermoplastic resin; and at least one fiber or fiber bundle disposed in the base material and extending in a strand-axial direction. Twisting is applied to the fiber or the fiber bundle along the strand-axial direction, and the number of times of the twisting per 1 m in length of the fiber-reinforced resin strand in the strand-axial direction is 30 or more and 80 or less.
Claims9
A fiber-reinforced resin strand used as a manufacturing material for a 3D printer, the fiber-reinforced resin strand comprising:
- a base material containing a thermoplastic resin;
- and
- at least one fiber or fiber bundle disposed in the base material and extending in a strand-axial direction, wherein
- twisting is applied to the fiber or the fiber bundle along the strand-axial direction, and
- a twisting angle of the twisting relative to the strand-axial direction is 1° or more and 4° or less.
An additive manufacturing method comprising:
- manufacturing a manufactured object by fused deposition modeling using a fiber-reinforced resin strand, the fiber-reinforced resin strand comprising:
- a base material containing a thermoplastic resin;
- and at least one fiber or fiber bundle disposed in the base material and extending in a strand-axial direction, twisting being applied to the fiber or the fiber bundle along the strand-axial direction, and a twisting angle of the twisting relative to the strand-axial direction being 1° or more and 4° or less.
