Abstract

The method of manufacturing the insulation member includes manufacturing a 3D printing material using a mixed material in which one or more materials selected from among polycarbonate (PC), polybutylene terephthalate (PBT), acrylonitrile-butadiene-styrene (ABS), polyamide (PA), polyoxymethylene (POM), and polyethylene terephthalate (PET), one or more fillers selected from among TiO2, SiO2, and AlO3, and a curing agent are mixed, and which contains different amounts of the fillers at predetermined intervals in a longitudinal direction, and sequentially stacking the manufactured 3D printing material using a 3D printer to thus manufacture a target insulation member so that the mixed material containing different amounts of the fillers at predetermined intervals in a longitudinal direction of the insulation member is sequentially stacked.

First claim

The invention claimed is:

1. A solid insulation member comprising:
a mixed material in which one or more materials selected from among polycarbonate (PC), polybutylene terephthalate (PBT), polyoxymethylene (POM), acrylonitrile-butadiene-styrene (ABS), polyamide (PA), and polyethylene terephthalate (PET), one or more fillers selected from among TiO 2 , SiO 2 , and Al 2 O 3 , and a curing agent are mixed,
wherein the mixed material containing different amounts of the fillers at predetermined intervals in a longitudinal direction is stacked.

2. The insulation member of claim 1 , wherein stacking is performed so that an amount of the filler is gradually increased stepwise from one side to another side in a longitudinal direction of a cross section of the insulation member.

3. The solid insulation member of claim 1 , wherein stacking is performed so that an amount of the filler is gradually increased stepwise from one side to a central part in the longitudinal direction of a cross section of the insulation member and so that the amount of the filler is gradually reduced stepwise from the central part to another side.

4. The solid insulation member of claim 1 , wherein the stacking is performed so as to be inclined at a predetermined angle relative to a virtual vertical line formed in the longitudinal direction of the cross section of the insulation member.

5. The solid insulation member of claim 4 , wherein a mixed material is stacked so as to contain a filler in an amount that is relatively larger in a terminal end of the insulation member, defined by a virtual central line forming an acute angle in a longitudinal direction with respect to a virtual horizontal line perpendicular to the virtual vertical line, than in a portion other than the terminal end.

6. A method of manufacturing a solid insulation member, the method comprising:
manufacturing a 3D printing material using a mixed material in which one or more materials selected from among polycarbonate (PC), polybutylene terephthalate (PBT), polyoxymethylene (POM), acrylonitrile-butadiene-styrene (ABS), polyamide (PA), and polyethylene terephthalate (PET), one or more fillers selected from among TiO 2 , SiO 2 , and Al 2 O 3 , and a curing agent are mixed, and which contains different amounts of the fillers at predetermined intervals in a longitudinal direction; and
sequentially stacking the manufactured 3D printing material using a 3D printer to thus manufacture a target insulation member so that the mixed material containing different amounts of the fillers at predetermined intervals in a longitudinal direction of a cross section of the target insulation member is sequentially stacked.

7. The method of claim 6 , wherein the stacking is performed so that an amount of the filler is gradually increased stepwise from one side to another side in the longitudinal direction of the cross section of the insulation member, thus manufacturing the insulation member.

8. The method of claim 6 , wherein the stacking is performed so that an amount of the filler is gradually reduced stepwise from one side to a central part in the longitudinal direction of the cross section of the insulation member and so that the amount of the filler is gradually increased from the central part to another side for each layer, thus manufacturing the insulation member.

9. The method of claim 6 , wherein, when the 3D printing material is stacked to manufacture the insulation member, the stacking is performed so as to be inclined at a predetermined angle relative to a virtual vertical line formed in the longitudinal direction of the cross section of the insulation member.

10. A solid insulation member manufactured using the method of manufacturing the solid insulation member of claim 6 .

11. A method of manufacturing a solid insulation member, the method comprising:
manufacturing n 3D printing materials using mixed materials in which one or more materials selected from among polycarbonate (PC), polybutylene terephthalate (PBT), polyoxymethylene (POM), acrylonitrile-butadiene-styrene (ABS), polyamide (PA), and polyethylene terephthalate (PET), one or more fillers selected from among TiO 2 , SiO 2 , and Al 2 O 3 , and a curing agent are mixed and which contain mutually different amounts of the fillers; and
sequentially stacking the manufactured n 3D printing materials using a 3D printer to thus manufacture a target insulation member so that a first 3D printing material to a n-th 3D printing material of the n 3D printing materials are stacked at predetermined intervals in a longitudinal direction of a cross section of the insulation member.

12. The method of claim 11 , wherein the stacking is performed so that an amount of the filler is gradually increased stepwise from one side to another side in the longitudinal direction of the cross section of the insulation member, thus manufacturing the insulation member.

13. The method of claim 11 , wherein the stacking is performed so that an amount of the filler is gradually reduced stepwise from one side to a central part in the longitudinal direction of the cross section of the insulation member and so that the amount of the filler is gradually increased from the central part to another side for each layer, thus manufacturing the insulation member.

14. The method of claim 11 , wherein, when the 3D printing material is stacked to manufacture the insulation member, the stacking is performed so as to be inclined at a predetermined angle relative to a virtual vertical line formed in the longitudinal direction of the cross section of the insulation member.

15. A solid insulation member manufactured using the method of manufacturing the solid insulation member of claim 11 .
