Embodiment 2

[0024] Embodiment 2, comprise the following steps in this processing technology:

[0025] (1) Prepare the following raw materials according to the weight ratio: PMMA, 95 parts, PCL, 7 parts, PHA, 3 parts, TPU, 3 parts;

[0026] (2) Grinding the above-mentioned raw materials into granules or powders and mixing uniformly, the diameter of the granules is 0.82mm;

[0027] (3) Heating the homogeneously mixed raw materials in step (2) to 223 degrees and maintaining for 35 minutes, so that the various raw materials are fully mixed together after melting;

[0028] (4) extruding the raw materials melted in step (3) into filaments, cooling and outputting to obtain filamentous solid printing materials.

[0029] The diameter of the filamentous solid in the molding process of the above step (4) is 1.25 mm. In this embodiment, the diameter of the generated consumable is relatively large, and its flexibility can meet the requirements, and the flow rate of the consumable can be slightly red...

Embodiment 3

[0030] Embodiment 3, comprise the following steps in this processing technology:

[0031] (1) Prepare the following raw materials according to the weight ratio: PMMA, 90 parts, PCL, 2 parts, PHA, 2.5 parts, TPU, 2.5 parts;

[0032] (2) Grinding the above-mentioned raw materials into granules or powders and mixing uniformly, the diameter of the granules is 0.82 mm;

[0033] (3) Heating the homogeneously mixed raw materials in step (2) to 220 degrees and maintaining for 30 minutes, so that the various raw materials are fully mixed together after melting;

Abstract

The invention discloses a 3D printing supplies forming method and a 3D printing supplies forming device. The 3D printing supplies forming device comprises a feeding hopper, a mixing chamber communicated with the feeding hopper, a heating chamber communicated with the mixing chamber, and a finished product outlet connected behind the heating chamber. In the technical scheme, the feeding hopper enables granular materials to be conveniently poured into the mixing chamber, the mixing chamber mixes the granular materials according to certain ratio, and then conveys the granular materials to the heating chamber, and the heating chamber heats the granular materials to be fused, and then conveys the obtained fused materials out.

Description

technical field [0001] The invention belongs to the field of 3D printing technical equipment, and in particular relates to a method for forming a 3D printing consumable and a production device for producing the consumable. Background technique [0002] In the field of dentistry, the demand for dentures has always been high. However, due to the traditional process of denture processing, the process is very complicated, which leads to high costs and seriously hinders the popularization and promotion of dentures. The traditional process includes: abutment preparation (same as removable denture)→creation of occlusal rest (same as casting rest)→production of functional impression→anhydrite reproduction model→teeth arrangement→making wax base and wax ring → Boxing (flip-chip method, exposing the base, clasp, and artificial teeth) → high-melting casting → wax removal → casting press → grinding and polishing → denture molding → wearing the mouth. Therefore, it is becoming more and ...
