Abstract
Official abstract text for this publication.
An object of the invention is to provide a filament for a material extrusion-type three-dimensional printer, which filament contains an aromatic polyester resin, and which overcomes the shortcomings of a filament for a material extrusion-type three-dimensional printer that is composed of an ABS resin. Provided is a filament for a material extrusion-type three-dimensional printer, the filament including an aromatic polyester resin containing 50 mol % or more of aromatic dicarboxylic acid units, and 3 mol % or more of isophthalic acid units, with respect to the total amount of dicarboxylic acid units. The aromatic polyester resin preferably has a melt flow rate (230° C., 2.16 kgf) of 7 g/10 min or more, and an intrinsic viscosity of 0.80 dL/g or less.
First claim
Opening claim text (preview).
The invention claimed is: 1. A filament for a material extrusion-type three-dimensional printer, the filament comprising: an aromatic polyester resin containing 50 mol % or more of aromatic dicarboxylic acid units, and 3 mol % or more of isophthalic acid units, with respect to the total amount of dicarboxylic acid units, wherein the aromatic polyester resin has a melt flow rate (230° C., 2.16 kgf) of 7 g/10 min or more and 100 g/10 min or less. 2. The filament for a material extrusion-type three-dimensional printer according to claim 1 , wherein the aromatic polyester resin comprises 50 mol % or more of ethylene glycol units with respect to the total amount of diol units. 3. The filament for a material extrusion-type three-dimensional printer according to claim 1 , wherein the aromatic polyester resin comprises 3 mol % or more and 50 mol % or less of isophthalic acid units with respect to the total amount of dicarboxylic acid units. 4. The filament for a material extrusion-type three-dimensional printer according to claim 1 , wherein the aromatic polyester resin has an intrinsic viscosity of 0.80 dL/g or less. 5. The filament for a material extrusion-type three-dimensional printer according to claim 1 , wherein the filament has a diameter of 1.0 mm or more and 5.0 mm or less. 6. A roll of filament obtainable by winding the filament for a material extrusion-type three-dimensional printer according to claim 1 . 7. A cartridge for a material extrusion-type three-dimensional printer, the cartridge comprising: a container; and the filament for a material extrusion-type three-dimensional printer according to claim 1 housed within the container. 8. A cartridge for a material extrusion-type three-dimensional printer, the cartridge comprising: a container; and the roll of filament according to claim 6 housed within the container. 9. A filament for a material extrusion-type three-dimensional printer, the filament comprising: an aromatic polyester resin containing terephthalic acid units and isophthalic acid units as dicarboxylic acid units, wherein wherein the aromatic polyester resin has a melt flow rate (230° C., 2.16 kgf) of 7 g/10 min or more and 100 g/10 min or less. 10. The filament for a material extrusion-type three-dimensional printer according to claim 9 , wherein the aromatic polyester resin comprises ethylene glycol units as diol units. 11. The filament for a material extrusion-type three-dimensional printer according to claim 1 , wherein the aromatic polyester resin comprises 12 mol % or more and 50 mol % or less of isophthalic acid units with respect to the total amount of dicarboxylic acid units.
