Abstract

The invention provides a three-dimensional molding system and method for flexible materials. The system includes: a feeder, which provides a polymer melt; a screw extruder, which extrudes the polymer melt; a metering pump, which controls the polymer flowing into the melt-blown nozzle. Quantity of melts; air compressors, to compress air; air heaters, to heat compressed air; three-dimensional forming devices, to form three-dimensional workpieces supporting flexible materials; melt-blown nozzles, including A spinneret and an air flow hole communicated with the air heater, the spinneret is provided with a melt hole, and a thin stream of polymer melt is sprayed to the three-dimensional workpiece, and the air stream hole draws the thin stream of the polymer melt Melt-blown fibers are formed to condense on the three-dimensional workpiece; a curing molding device is connected to the three-dimensional workpiece, and solidifies the melt-blown fibers condensed on the three-dimensional workpiece to generate flexible materials. The invention can realize convenient and fast printing of flexible materials.

Description

technical field [0001] The invention relates to a flexible material three-dimensional forming system and method. Background technique [0002] 3D printing (3D printing, three-dimensional prototyping) is a kind of three-dimensional rapid prototyping technology. It is based on digital model files, using powdered metal or plastic and other bondable materials to construct objects by layer-by-layer printing. Technology. [0003] 3D printing is usually achieved using digital technology material printers. In the past, it was often used to make models in the fields of mold manufacturing and industrial design, and is now gradually being used in the direct manufacture of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms...
