Abstract

The invention discloses a FDM (fused deposition modeling) 3 D (three dimensional) printing cold plate molding resin membrane which has a thickness of 50-250mum, and comprises a hot melt layer, a base layer and a non-setting adhesive layer, the thickness ratio of hot melt layer to base layer to non-setting adhesive layer is 17-23:17-23:9-11; the hot melt layer is ethylene-vinyl acetate copolymer; the base layer contains high density polyethylene (75-85wt%), linear low density polyethylene (5-15wt%) and calcium carbonate (1-10wt%); the non-setting adhesive layer is an oily non-setting adhesive. The FDM (fused deposition modeling) 3 D (three dimensional) printing cold plate molding resin membrane has the advantages of low cost, when in use, a baseplate with a smooth and flat surface is required, and special requirements on the texture are not required. The problem of high cost of traditional 3D printing baseplates and adhesive films can be solved, and the problems of low safety and large machine loss caused by heating of the baseplates can be solved. In addition, the FDM (fused deposition modeling) 3 D (three dimensional) printing cold plate molding resin membrane is not only suitable for printing small-sized items, but also suitable for printing large-sized items (with the length, width and height up to 500mm), and edge warping problem may not be produced when in printing of the large-sized items.

Description

technical field [0001] The invention relates to an adhesive film on a bottom plate of a 3D printer, in particular to an FDM3D printing cold plate forming resin film. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. There are many ways of 3D printing. One is the printer produced by Objet, which uses an inkjet head to spray an ultra-thin liquid plastic layer on a tray, and solidifies it through ultraviolet radiation, and then lowers the tray slightly. Add new TLCs on top of TLCs. Another way is fused deposition modeling (FDM), which is applied by Minneapolis-based Stratasy. The specific process of FDM 3D printing is to melt the plastic in a (printing) head, and then spray Filamentous material is drawn out and attached to the bottom plate to form a thin layer, and then the bottom pla...
