Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] Such as figure 1 As shown, a self-fusing FDM wire for 3D printing is a 3D printing consumable for fused deposition modeling. The heating layer 2 and the forming layer 1 can use thermoplastics used in general FDM consumables to form the main structure of the object to be printed. The heating layer 2 is used to heat the forming layer 1 to make the specific forming layer 1 melt or melt . The material of the molding layer 1 in the present invention is pre...

Abstract

The invention discloses a FDM wire rod for self-melting 3D printing. The FDM wire rod for the self-melting 3D printing comprises a forming layer and a heating layer; the heating layer is arranged inside the forming layer, the heating layer is arranged in the length direction of the forming layer and extends out of one end of the forming layer, the heating layer comprises two conductive wires, thecorresponding end heads of the two conductive wires abut against each other to form an abutting region and are separated along the end heads to form a separation region, and the other corresponding end heads of the two conductive wires extend out of the forming layer to form a joint region. The FDM wire rod for the 3D printing does not need to be heated and melted by means of a hot melting spray head, the 3D printing equipment is simplified through conductive heating and self-melting, and the 3D printing cost is saved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a self-fusing FDM wire for 3D printing. Background technique [0002] 3D printing is a cumulative manufacturing technology, that is, rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials to print layers of bonding materials. Create three-dimensional objects. At present, the most widely used printing process in 3D printing technology is the FDM process, that is, the fused deposition manufacturing process. The consumables are generally thermoplastic materials, such as wax, ABS, nylon, etc., and are supplied in the form of filaments or rods. High temperature is required for 3D printing. In the nozzle, the material is heated and melted in the nozzle. The nozzle moves along the section profile of the part and the filling track while extruding the molten material. The material solidifies rapidly...
