Problems solved by technology

However, among these methods, the case of the thermosetting type is a relatively simple manufacturing process in which polymer filaments are thermally melted at designated points, extruded and dropped to complete shapes laminated layer by layer, but there are shapes such as the following Problems: imprecise shape and uneven solidification due to equipment heating, phase separation between organic / inorganic composites, and thermal shrinkage due to heating / cooling
In addition, the case of photocurable type can be accurately expressed, but there are problems such as device size, storage, and low hardness after curing

Embodiment 1

[0064] As a thermosetting compound, an epoxy resin (YD-128 from Kukdo Chemical Co., Ltd.) and trimethylolpropane triglycidyl ether were introduced into a mixing vessel at a weight ratio of 95:5, respectively. The following was introduced into a mixing container to prepare a composition for 3D printing: 5 parts by weight of FeOFe which is a soft magnetic material (soft type) as magnetic particles, relative to 100 parts by weight of a thermosetting compound 2 o 3 Particles (multi-domain, coercive force 94 kOe, saturation magnetization value 80 EM units / g, particle size about 100 nm: measured by field emission scanning electron microscope (using DLS)), 5 parts by weight of thermoplastic resin Acrylic resin (B60 from DOW Plaroid), and 0.5 parts by weight of SI-B2A curing agent from SamShin Chemical Co., Ltd. as a thermal curing agent.

[0065] Immediately after the 3D printing composition was laminated on the support through the nozzle in the feeding device, a magnetic field was ...

Embodiment 2

[0067] A composition for 3D printing was prepared in the same manner as in Example 1, except that an acrylic resin (A14 from DOW Plaroid Co.) was used as the thermoplastic resin, and a three-dimensional shape was allowed to be formed.

Embodiment 3

[0069] A composition for 3D printing was prepared in the same manner as in Example 1, except that high-density polyethylene (HDPE) from LGChem was used as the thermoplastic resin, and a three-dimensional shape was formed.

Description

technical field [0001] Cross References to Related Applications [0002] This application claims the benefit of priority based on Korean Patent Application No. 10-2016-0015131 filed on February 5, 2016, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present application relates to a composition for 3D printing, a 3D printing method using the same, and a three-dimensional shape comprising the same. Background technique [0004] A three-dimensional printer has a three-dimensional printing mechanism configured to form a physical object in three dimensions. Research on a resin composition for 3D printing as a three-dimensional printing ink for three-dimensionally forming a physical object by such a three-dimensional printer is continuing. [0005] In realizing a desired pattern or three-dimensional shape, a conventional 3D printing method has been performed by a method of curing a resin composition by means of heat...
