Abstract
A filament for three-dimensional modeling includes two or more kinds of resins; a fiber; and a compatibilizing agent, and has a sea-island structure including a sea part and island parts, the sea part including at least one kind of the two or more kinds of resins and the island parts including at least one kind of the two kinds of resins.
Claims12
A filament for three-dimensional modeling,
- comprising
- a first resin and a second resin having a difference in solubility parameter of 5 or more;
- a fiber;
- and
- a compatibilizing agent, and
- having a sea-island structure including a sea part and island parts, the sea part including the first resin and the island parts including the second resin,
- wherein:
- at least a part of the island part coats at least a part of a surface of the fiber,
- in a cross section of the filament in a direction orthogonal to a longitudinal axis of the filament, the island parts have a diameter of 0.1 μm or more and 20 μm or less, and
- S2/S1×100 is 5% or more and 49% or less, where:
- S1 represents an area obtained by subtracting an area occupied by the fiber from a total area of a cross section of the filament in a direction orthogonal to a longitudinal axis of the filament, and
- S2 represents a total area of the island parts in the cross section.
