Embodiment Construction
[0031] Examples of 3D printing materials:
[0032] The three-dimensional printing material of this embodiment is used in an FDM three-dimensional printer. The three-dimensional printing material is composed of metal powder and a binder, wherein the mass fraction of the metal powder is 60% to 70%; the mass fraction of the binder is 30% to 40%. The three-dimensional printing material is formed by uniformly mixing metal powder and binder, or the three-dimensional printing material is formed by mixing metal powder and water-soluble binder to form strip printing material. Specifically, the following table gives examples of five proportioning methods of 3D printing materials.
[0033]
[0034] In some embodiments of 3D printing materials, the binder is water-soluble binder or paraffin, and the metal powder is bronze, cobalt-based alloy, copper-based alloy, gold-based alloy, nickel-based alloy, stainless steel, iron, lead / zinc alloy. The water-soluble binders are polyethylene g...

Abstract
The invention relates to a three-dimensional printing material, a fused deposition modeling (FDM) three-dimensional printer and a printing method of the FDM three-dimensional printer. The three-dimensional printing material is used for the FDM three-dimensional printer. The three-dimensional printing material is prepared from, by mass, 60%-70% of metal powder and 30-40% of adhesives. The FDM three-dimensional printer comprises a printing head, a heating device, a printing platform, a water tank and a sinter molding chamber. The printing method comprises the step of primary molding and the step of sinter molding. By the adoption of the three-dimensional printing material, the FDM three-dimensional printer and the printing method of the FDM three-dimensional printer, the problems that an existing FDM three-dimensional printer is slow in molding, and existing selective laser melting (SLM) printing is large in power consumption are solved.
Description
technical field [0001] The invention relates to the field of three-dimensional printing, in particular to an FDM type three-dimensional printing material, a three-dimensional printer and a printing method. Background technique [0002] Three-dimensional (3D) rapid prototyping, also known as additive manufacturing, is based on the principle of producing three-dimensional objects by printing or laying down successive layers of material. A 3D rapid prototyping device, or 3D printer, works by converting a 3D computer model of an object and producing a series of cross-sectional slices, which are then printed, one on top of the other, to produce the final 3D object. [0003] The methods of three-dimensional rapid prototyping mainly include the following types: stereolithography or photocuring (Stereolithography, SLA), layered object manufacturing (Laminated object manufacturing, LOM), selective laser melting (Selective laser melting, SLM), fused deposition modeling (Fused depositi...
