High-temperature consumable wire drawing equipment for 3D printing

Abstract

The invention provides high-temperature consumable wire drawing equipment for 3D printing. The high-temperature consumable wire drawing equipment for the 3D printing comprises an extruder, a forced cooling zone, an annealing wire drawing zone, a slow cooling zone, wire winding equipment and a controller; the forced cooling zone comprises a forced cooling air hood and forced cooling devices; the annealing wire drawing zone comprises wire drawing orifice plates and a heater; and the slow cooling zone comprises a slow cooling air hood, a slow cooling device and a sliding windscreen. Compared with the prior art, the high-temperature consumable wire drawing equipment for the 3D printing has smaller size, higher processing speed and better uniformity, is more convenient for preparation liquid of semi-crystalline and non-crystalline materials, and has better universality for different materials.

Description

technical field [0001] The invention relates to the field of new equipment manufacturing, in particular to a wire drawing equipment for high-temperature consumables for 3D printing. Background technique [0002] Additive manufacturing technology (also known as "3D printing") is a method of directly manufacturing three-dimensional physical entities in a layer-by-layer manner based on a computer-based three-dimensional CAD model. Additive manufacturing technology can quickly and precisely manufacture parts of any complex shape and structure on one piece of equipment, thus realizing "free manufacturing". Compared with traditional processing technology, additive manufacturing can reduce processing costs by more than 20%-40%, and shorten product development cycle by about 80%. In the past 20 years, additive manufacturing technology has developed rapidly, and a variety of molding technologies and equipment have been formed. These technologies are aimed at high-end manufacturing ...

AI Technical Summary

Problems solved by technology

Especially for high-temperature thermoplastic materials, in order to ensure accuracy, the entire equipment is large in size or the processing speed is very slow, which is not convenient for laboratory research and development equipment

Moreover, it is difficult to prepare certain semi-crystalline or amorphous consumables for FDM

Restricted by the different shrinkage rates of materials, each material requires a mold with a specific aperture corresponding to it, and the versatility is poor
