Abstract
The invention provides a three-dimensional flexible material molding system and a three-dimensional flexible material molding method. The system comprises a feeder, a screw extruder, a metering pump, an air compressor, an air heater, a three-dimensional molding device, a melt-blowing nozzle and a solidification molding device, wherein the feeder is used for feeding molten polymers; the screw extruder is used for extruding the molten polymers; the metering pump is used for controlling the number of the molten polymers flowing into the melt-blowing nozzle; the air compressor is used for compressing air; the air heater is used for heating the compressed air; the three-dimensional molding device is used for processing and molding a three-dimensional workpiece for supporting a flexible material; the melt-blowing nozzle comprises a spinneret plate communicated with the metering pump and an air flow hole communicated with the air heater; a melt hole is formed in the spinneret plate; thin molten polymer flows are blown to the three-dimensional workpiece and are drawn into melt-blowing fibers through the air flow hole to be agglomerated on the three-dimensional workpiece; the solidification molding device is communicated with the three-dimensional workpiece and is used for solidifying the melt-blowing fibers agglomerated on the three-dimensional workpiece to generate the flexible material. According to the system and the method, the flexible material can be conveniently and quickly printed.
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...
