Embodiment 1

[0051] Using 1% metallic aluminum silver powder and 99% PLA (polylactide polylactic acid), the imitation silver composite consumables for 3D printing are produced through the following formula. Concrete preparation steps are as follows:

[0052] ①. Mix 1% metal aluminum silver powder and 99% PLA;

[0053] ② Put the prepared raw materials into a plastic dryer and dry at 80°C-100°C for 2-3 hours;

[0054] ③. Put the raw materials into the plastic extruder, heat them at a temperature of 180°C-210°C, plasticize and dissolve the raw materials in the screw barrel at high temperature, and extrude the raw materials at a screw speed of 30-60 RPM;

[0055] ④. The raw material extruded from the screw passes through the honeycomb extrusion die, and then enters the inner tapered stainless steel extrusion die to extrude the plastic line;

[0056] ⑤. The plastic line enters a 6-meter-long 10°C-15°C water tank with ice water to fully cool the forming wire;

[0057] ⑥. The wire enters the t...

Embodiment 2

[0061] Using 30% metal aluminum silver powder and 70% PLA, the imitation silver composite consumables for 3D printing are produced through the following formula. Concrete preparation steps are as follows:

[0062] ①. Mix 30% metal aluminum silver powder and 70% PLA;

[0063] ② Put the prepared raw materials into the dryer and dry them at a temperature of 90°C-100°C for more than 2 hours to reduce the moisture content of the raw materials to 0.2%-0.5%;

[0064]③. Put the dried raw materials into a plastic mixer and mix them thoroughly for 30 minutes;

[0065] ④. Put the mixed raw materials into the twin-screw granulator, heat at a temperature of 180°C-210°C, plasticize and dissolve the raw materials in the screw barrel at high temperature, and then extrude the raw materials at a screw speed of 30-60RPM;

[0066] ⑤. After the raw material extruded from the screw enters the granulation die, it is differentiated into thin strips, and is quickly cut into composite particles with ...

Embodiment 3

[0075] Using 10% metal aluminum silver powder and 90% PLA, the imitation silver composite consumables for 3D printing are produced through the following formula. Concrete preparation steps are as follows:

[0076] ①. Mix 10% metal aluminum silver powder and 90% PLA;

[0077] ② Put the prepared raw materials into the dryer and dry them at a temperature of 90°C-100°C for more than 2 hours to reduce the moisture content of the raw materials to 0.2%-0.5%;

[0078] ③. Put the dried raw materials into a plastic mixer and mix them thoroughly for 30 minutes;

[0079] ④. Put the mixed raw materials into the twin-screw granulator, heat at a temperature of 180°C-210°C, plasticize and dissolve the raw materials in the screw barrel at high temperature, and then extrude the raw materials at a screw speed of 30-60RPM;

[0080] ⑤. After the raw material extruded from the screw enters the granulation die, it is differentiated into thin strips, and is quickly cut into composite particles with...

Abstract

The invention provides an imitation-silver composite consumable with a silver plating effect and for 3Dprinting, which comprises the following components in percentage by mass: 1-30% of metal aluminum silver powder, and 70-99% of PLA (polylactic acid). Because a product formed by filling the metal aluminum silver powder into a PLA plastic material is used as a main material of the 3D printing consumable, a model finished product prepared by printing the 3D printing consumable has a glittering silver luster without being subjected to chemical or physical polishing, and has silvering luster and texture similar as those of silver metals, and the model finished product also has the characteristics of no toxicity, high-temperature resistance, acid and alkali resistance, light resistance, and no discoloration, and the like, so that one more consumable for 3D printing is developed, therefore, the 3D printing of imitation-silver metal models and products with a silver-plating effect becomes reality.

Description

technical field [0001] The invention relates to a 3D printing consumable, in particular to a silver-imitation composite consumable with silver plating effect and a preparation method thereof. Background technique [0002] At present, the consumables of 3D printers used in China for the principle of FDM (Fused Deposition Manufacturing) have not yet appeared silver-like metal composite consumables with silver-plated effects for 3D printing. [0003] The imitation silver composite consumables with silver plating effect greatly save the cost of raw materials without using real silver metal as the raw material. and industrial applications. Contents of the invention [0004] Aiming at the blank spot of the above-mentioned consumables in the 3D printing market, the purpose of the present invention is to provide a silver-like composite consumable with a silver-plated effect, so that the finished model printed by the 3D printing consumable has the same silver-plated luster and te...
