[0093] The filament and the manufacturing method of the filament of the present invention will be described in detail based on the first embodiment and examples.

[0094] Filament manufacturing process

[0095] The filaments in this embodiment are produced by a general extrusion molding machine.

[0096] Specifically, a 65φ extruder was used. Cylinder temperature ranges from 150°C to 180°C for the die, 160°C to 200°C for the metering section, 160°C to 200°C for the compression section, and 150°C to 180°C for the supply section.

[0097] In addition, the limit temperature is 240°C, the temperature of the cooling water in the cooling water tank is 8°C to 15°C, the distance between the mold and the classifier is 2cm to 5cm, the take-out rate is 0.87 to 0.92, and the sizing method is drive.

[0098] The filament in this embodiment is after mixing the particles of the polylactic acid resin (A) and the particles of the thermoplastic elastomer (B) with a total weight of 100%, addin...

Abstract

To provide filaments that can impart an arbitrary hardness to a three-dimensional molded article and do not bend during transport, and a method for producing the same. In the present invention, a polylactic acid resin and a thermoplastic elastomer are contained to configure filaments used as a raw material of a printed article printed by a 3D printer using fused deposition modeling (FDM).

Description

technical field [0001] The invention relates to a printing material-filament used in a hot-melt lamination method (FDM) three-dimensional printing device and a manufacturing method thereof. Background technique [0002] Traditionally, 3D printing equipment is used to create three-dimensional figures, such as prototypes or molds. A three-dimensional printing device, also called a 3D printer, can create a three-dimensional shape by using raw materials such as resin based on three-dimensional drawing data captured on a computer. [0003] There are many ways to make three-dimensional figures, one of which is fusion lamination (FDM). The hot melt lamination method (FDM) is a kind of raw material filament such as thermoplastic resin, which is heated and dissolved by the heater installed in the print head, and discharged from the nozzle. For example, the nozzle is operated in the plane direction to form a three-dimensional product. One layer, and then layer the second layer and t...
