Problems solved by technology

However, limited by the size and micro-bonding of the powder, it is impossible to completely remove the powder from the pores, especially the curved and closed bottom pores. The traditional method cannot achieve complete removal even if the treatment time is long, and it is labor-intensive. There is a huge waste of energy

Embodiment 1

[0034] Embodiment 1 provides a method for cleaning PEEK powder according to the method described in this patent. The specific plan is as follows:

[0035] Dimethyl sulfoxide and ethanol are used as raw materials to form a solution with a certain ratio, and the volume fraction is 4:1, and then the capillary tube with the bonded PEEK powder is put into it, and the powder is washed by ultrasonic vibration at a certain temperature. out.

[0036] Under normal pressure, the ultrasonic cleaning time is 10 minutes, and the temperature is 25°C. The final performance is that the bonded powder is cleared out, such as figure 2 shown in .

Embodiment 2

[0038] This embodiment provides a method for cleaning PEEK powder. Compared with Example 1, this example differs in that:

[0039] The cleaning liquid was replaced with ethanol, and the others remained unchanged.

[0040] After cleaning, the powder block still exists, a small amount of powder flakes off, and the cleaning effect is poor, such as image 3 .

Embodiment 3

[0042] This embodiment provides a method for cleaning PEEK powder. Compared with Example 1, this example differs in that:

[0043] Change the cleaning liquid to cyclohexanone, and treat the sample as PEEK powder.

[0044] After cleaning, the powder block still exists, part of the powder flakes off, and the cleaning effect is poor, such as Figure 5 No. 1 test tube.

Abstract

The invention discloses a method for cleaning away small-size pore powder of a PEEK material 3D printing product. The method comprises the following steps that S1, a cleaning solution is prepared; S2, the PEEK 3D printing product is dried and then placed in the cleaning solution obtained after sealing treatment, and an ultrasonic instrument is placed in the solution; S3, the temperature of the solution is regulated and controlled to be 25-70 DEG C; and S4, the cleaning time of the ultrasonic instrument is controlled to be 5-10 minutes. According to the obtained solution and a use method, the cleaning speed is high, the cleaning effect is good, touch damage is avoided, and the powder-free 3D printing product can be obtained rapidly and conveniently.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a method for cleaning small-sized pore powder of PEEK material 3D printing products. Background technique [0002] Additive manufacturing, commonly known as 3D printing, integrates computer-aided design, material processing and molding technology, and is based on digital model files. A manufacturing technology that builds up layers of methods to create physical objects. Compared with traditional subtractive technologies such as cutting, the biggest advantage of additive manufacturing technology is that it can realize the manufacture of complex structural parts. In the current non-metallic 3D printing research, PEEK has attracted widespread attention because of its excellent heat resistance and excellent mechanical properties. The German EOS company has also launched the world's first 3D printer using PEEK powder laser sintering technology EOS P800 . This 3D printer can pri...
