Description

BL-5432 GAS-DRIVEN 3D PRINTING MATERIAL, PREPARATION METHOD AND LU501553
APPLICATION THEREOF TECHNICAL FIELD
[01] The disclosure relates to the technical field of 3D printing, and in particular, to a gas- driven 3D printing material, a preparation method and an application thereof.
BACKGROUND ART
[02] In recent years, 3D printing technology is rapidly developed as an innovative technology, and has been widely applied due to continually improved printing accuracy and printing efficiency. Theoretically, a layer-by-layer superposition method is used for the technology, the process is not influenced by entity prototype complexity and is applicable to the rapid manufacturing of various parts with complex structures, so that 3D printing technology is more and more widely concerned at home and abroad. At present, by molding technology principles, the 3D printing technology can be divided into SLA (Stereo Lithography Appearance), SLS (Selective Laser Sintering), DIW (Direct Ink Writing), FDM (Fused Deposition Modeling), LOM (Laminated Object Manufacturing), etc. Therein, the DIW technology has been widely applied due to wider material applicability and simple operability thereof, and especially plays an important role in the printing of such materials as ceramics, cements and plasters which mainly rely on slurry molding.
[03] At present, as mentioned above, 3D printing materials for the DIW technology mainly include ceramic-based, cement-based and plaster-based materials, etc. For the ceramic-based 3D printing technology, relatively complex after-treatment processes are needed after blank extrusion molding, and such after-treatment processes as sintering process may severely influence printing accuracy thereof. For the cement-based and plaster-based 3D printing materials, the coagulation time thereof needs to be controlled to meet printing requirements; shrinkage behaviors of the two materials in a hydration and hardening process may significantly influence quality of a printed product. Moreover, the three printing materials cannot achieve the printing process and the hardening process synchronously, thus failing to play the technical advantage of the rapid molding of the 3D printing technology.
SUMMARY
[04] In view of this, the disclosure aims to propose a gas-driven 3D printing material to solve the problems of poor printing quality and low printing efficiency of existing 3D printing materials.
[05] To achieve this objective, the technical solutions of the disclosure are as follows:
[06] A gas-driven 3D printing material comprises the following components in parts by weight: 100 parts of a carbonized gelling material, 10-15 parts of a carbonized reinforcement phase, 1-2 parts of a binding agent and 28-38 parts of water.
[07] Optionally, the carbonized gelling material is one or more of y-dicalcium silicate, monocalcium silicate, tricalcium disilicate, steel slag powder and silicate cement mixture; the particle size of the carbonized gelling material is 2-10 pm. 1
BL-5432
[08] Optionally, when the carbonized gelling material is steel slag powder and silicate cement mixture, the gas-driven 3D printing material furthermore comprises 1-2 parts by weight LU501553 of water reducing agent.
[09] Optionally, the carbonized reinforcement phase is one or more of chitosan and amorphous silicone material.
[10] Optionally, the binding agent is one or more of polyethylene glycol, polyvinyl alcohol, waterborne polyurethane, ethylene-vinyl acetate ~~ copolymer and sodium carboxymethylcellulose.
[11] Optionally, the water reducing agent is a composite water reducing agent prepared by mixing polycarboxylate-type high-efficiency water reducing agent and sodium citrate retarder.
[12] The second objective of the disclosure is to provide a method for preparing the gas- driven 3D printing material, comprising the following steps:
[13] ball-milling the carbonized gelling material and the carbonized reinforcement phase to obtain a mixture A;
[14] dissolving the binding agent in the water to obtain a solution B;
[15] adding the mixture A into the solution B and stirring to obtain a gas-driven 3D printing material.
[16] The third objective of the disclosure is to provide an application of the gas-driven 3D printing material in 3D printing, comprising the following steps:
[17] constructing an objective printing model through 3D data modeling;
[18] slicing the objective printing model and planning a scanning line;
[19] referencing to size and printing accuracy requirements of the objective printing model slice, and matching suitable printing parameters;
[20] after removing bubbles in the gas-driven 3D printing material, filling the material into a charging barrel of a 3D printer;
[21] starting an infrared radiation heater to preheat a printing area, introducing CO» gas into the sealed printing area for air discharge, and then starting printing;
[22] after printing, carrying out carbonization and hardening treatment to obtain a printed product.
[23] Optionally, carbonization and hardening treatment temperature is 0-100°C, relative humidity is 5-100% and carbon dioxide concentration is 10-100%.
[24] Compared with the prior art, the gas-driven 3D printing material of the disclosure has the following advantages: 2
BL-5432
[25] 1. In the disclosure, the carbonized gelling material is used as a main material, together with the carbonized reinforcement phase, the binding agent and the water, to prepare the 3D LU501553 printing material. On the one hand, the carbonized gelling material can rapidly react with carbon dioxide in a proper carbonization environment to generate compact calcium carbonate hardened objects, so that a printed product has excellent volume stability, mechanical property and durability. On the other hand, the binding agent and the water reducing agent enable the 3D printing material of the disclosure to have certain stability, so that the material can keep the form thereof after being extruded from a nozzle and before being carbonized to prevent collapse and deformation and further improve printing quality. Moreover, the 3D printing material is mainly prepared by the carbonized gelling material, so that carbonization and hardening operations can be performed simultaneously in a printing process to achieve synchronous printing process and hardening process, greatly reduce molding time and further significantly improve printing efficiency.
[26] 2. The disclosure utilizes a slurry DIW 3D printing technology, with simple printing process operations. The gas-driven 3D printing material has good mobility and stability, thus the disclosure has a relatively high printing accuracy.
