preparation example Construction

[0040] See figure 1 , a method for preparing a 3D printing wax model support material based on MJP technology according to an embodiment of the present invention, comprising the following steps:

[0041] S10. Mix 50-75 parts of the wax substance and 5-20 parts of the higher fatty alcohol according to the parts by mass, and uniformly melt to obtain the base wax liquid.

[0042] Preferably, 50-75 parts of waxy substances and 5-20 parts of higher aliphatic alcohols are mixed in parts by mass, and in the operation of uniform melting: maintain the mixing temperature at 100°C-110°C. Since the above-mentioned raw materials are not solid, maintaining the mixing temperature at 100°C-110°C can make the raw materials better mixed evenly.

[0043] S20. Add 5-15 parts of tackifier and 5-15 parts of toughening agent into the basic wax liquid according to the parts by mass, and mix uniformly to obtain the wax liquid.

[0044] Preferably, the homogeneous mixing operation is: mixing by stirrin...

Embodiment 1

[0052] Add 72.4g of polyethylene glycol wax and 6.5g of cetyl alcohol into the reaction kettle, control the temperature to 100°C, and obtain the basic wax liquid after uniform melting.

[0053] Add 14.7g of water-based rosin resin, 5.3g of polyvinyl alcohol, 1g of polysorbate-80 and 0.1g of butyl hydroxyanisole into the above-mentioned basic wax liquid, control the temperature at 100°C, and stir at a stirring speed of 450r / min for 2h Afterwards a wax solution is obtained.

[0054] The above wax liquid is filtered through a suction filter bottle with a 5 μm filter element, and the filtrate is bottled to obtain a 3D printing wax model support material based on MJP technology.

Embodiment 2

[0056] Add 39.3g of polyethylene glycol wax, 9.8g of water-soluble silicone wax and 20g of behenyl alcohol into the reaction kettle according to mass percentage, adjust the temperature at 100°C, and obtain the basic wax liquid after uniform melting.

[0057] Add 10.3g rosin polyol ester resin, 4.5g alkyd resin, 9.4g polyacrylamide, 5.6g gelatin, 1g cetearyl alcohol and 0.1g 2,6-di-tert-butyl p-cresol to the above basic wax liquid In the process, the temperature was controlled at 110° C., and the wax liquid was obtained after stirring at a stirring speed of 800 r / min for 1 h.

[0058] The above wax liquid is filtered through a suction filter bottle with a 5 μm filter element, and the filtrate is bottled to obtain a 3D printing wax model support material based on MJP technology.

Abstract

The invention relates to a 3D printing wax pattern support material based on MJP technology and a preparation method thereof, comprising the following raw materials in parts by mass: 50-75 parts of waxy substances, 5-20 parts of higher fatty alcohols, 5 parts ‑15 parts of tackifier and 5 parts of ‑15 parts of toughening agent. The above-mentioned 3D printing wax model support material based on MJP technology is obtained by using low-cost raw materials, adding higher fatty alcohols, tackifiers and toughening agents on the basis of wax substances, and reasonably controlling the appropriate ratio. The 3D printing wax model support material based on MJP technology has strong toughness and high hardness, and it will not collapse or plug when applied to MJP technology. In addition, the above-mentioned raw materials are soluble in a mixed solvent of water, alcohols and alcohol polymers, and the subsequent cleaning and removal will not damage the wax model.

Description

technical field [0001] The invention relates to the technical field of 3D printing materials, in particular to a 3D printing wax pattern support material based on MJP technology and a preparation method thereof. Background technique [0002] 3D printing, also known as additive manufacturing, is a technology based on digital model files (usually STL or CAD files), using materials such as plastic, wax, ceramics and metals, to realize the construction of objects by layer-by-layer stacking. In recent years, with the advancement and development of science and technology, 3D printing has gradually penetrated into the fields of jewelry casting, dental casting and high-end precision casting, bringing new drivers and changes to these fields. Compared with traditional carving wax, machining wax, and pressed film wax pattern, 3D printing wax mold has the advantages of reducing processing time, reducing production cost, flexible batch operation, and meeting the requirements of wax patte...
