Abstract
The present invention provides a system for 3D prototyping of flexible material and method thereof The system comprises: a loading machine for providing a polymer molten mass; a screw extruding machine for extruding the polymer molten mass; a metering pump for controlling the quantity of the polymer molten mass; an air compressor for compressing air; an air heater for heating the compressed air; a 3D modeling component for processing a 3D workpiece; the nozzle comprises a spinneret plate and a gas-flow hole, the spinneret plate is configured with a through hole for forming the extruded polymer molten mass into a polymer melt trickle, the gas-flow hole drafts the polymer melt trickle to a filiform polymer fiber to aggregate on the 3D workpiece; a solidifying component for solidifying the filiform polymer fiber to form the flexible material. The present invention can achieve convenient and quick printing for the flexible material.
