Embodiment 1

[0031] Embodiment one: be used for the preparation method of 3D printing PCL material, operate and produce according to the following steps:

[0032] Step 1: First add 80g of polycaprolactone, 20g of starch, 44681g of chain extender, 5g of lubricant calcium stearate, 0.5g of antibacterial agent, 5g of silicon dioxide, and 5g of polyethylene glycol into the sealed bag, and manually Shake the material well, weigh the material according to the formula ratio, and at the same time, the formula seriously affects the melting point of PCL to determine the 3D printing performance of the finished PCL. Bake for several hours to increase the viscosity of PCL and make it easier to mix evenly;

[0033]The second step: add a part of the blended materials to the twin-screw extruder for car washing, clean the twin-screw extruder, add the remaining materials for twin-screw blending, and extrude the wire rod extruded by the twin-screw extruder Granulate through a granulator, extrusion temperatu...

Embodiment 2

[0037] Embodiment two: be used for the preparation method of 3D printing PCL material, operate and produce according to the following steps:

[0038] Step 1: First add 95g of polycaprolactone, 5g of starch, 44681g of chain extender, 5g of lubricant calcium stearate, 0.5g of antibacterial agent, 3g of silicon dioxide, and 15g of polyethylene glycol into the sealed bag, and manually Shake the material well, and weigh the material according to the formula ratio. The formula seriously affects the melting point of PCL to determine the 3D printing performance of the finished PCL. At the same time, put the material in a sealed bag at room temperature, shake it well, and put it in the oven Several hours make the viscosity of PCL rise so that it is easier to mix evenly;

[0039] The second step: add a part of the blended materials to the twin-screw extruder for car washing, clean the twin-screw extruder, add the remaining materials for twin-screw blending, and extrude the wire rod extr...

Abstract

The present invention relates to the technical field of preparation of high polymer materials, and discloses a preparation device and method of a PCL material for 3D printing. The preparation method includes the steps: firstly, adding 80-95 g of polycaprolactone, 5-20 g of starch, 1 g of chain extender 4468, 5 g of calcium stearate serving as a lubricant, 0.5 g of antibacterial agent, 3-5 g of silicon dioxide and 5-15 g of polyethylene glycol into a sealed bag; manually shaking up the materials; and weighing the materials according to a formula ratio. According to the preparation device and method for the PCL material for 3D printing, the material is low in printing temperature, high in precision and good in printing performance. Meanwhile, the preparation method disclosed by the present invention is simple and easy to implement, conditions are controllable, and the preparation cost is low; and the prepared low-temperature 3D printing consumable is low in 3D printing equipment requirements and wide in selectivity and can be used by common household 3D printers, so that the application range of the materials is wider, more people can perform 3D printing on the material, and the printing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation, in particular to a preparation device and a preparation method for 3D printing PCL materials. Background technique [0002] The fused deposition molding process is a molding method that melts various filaments (such as engineering plastics ABS, polycarbonate PC, etc.) After the printing head is extruded, it is solidified, and finally arranged in a three-dimensional space to form a three-dimensional object. Fused deposition modeling is a kind of 3D printing technology, which plays a vital role in the field of 3D printing. This is due to its relatively simple molding method, high molding precision, good hardness of the printed model, strong promotion, does not rely on laser as the molding energy, and the cost of printing equipment is low, so it has become the most popular 3D printing technology at present. [0003] However, some commonly used FDM 3D printing thermoplastic mat...
