Embodiment 1

[0119] Weigh 116.12g of hydroxyethyl acrylate, 0.25g of p-hydroxyanisole, 0.25g of antioxidant 168, and 100g of succinic anhydride in a reaction flask, start stirring, gradually raise the temperature to 120°C and keep it warm. After 2 hours of heat preservation, the measured acid value was lower than 260 mgKOH / g, and the temperature was lowered to discharge to obtain the carboxyl group-containing acrylate monomer D-11.

Embodiment 2

[0121] Weigh 88.11g of ethylene glycol monovinyl ether, 0.24g of p-hydroxyanisole, 0.24g of antioxidant 1010, and 148.11g of phthalic anhydride (phthalic anhydride) in a reaction bottle, start stirring, and gradually raise the temperature to 118°C And keep warm. After 2 hours of heat preservation, the measured acid value was lower than 237mgKOH / g, and the temperature was lowered to discharge to obtain carboxyl group-containing vinyl ether monomer D-21.

Embodiment 3

[0123] Weigh 102.13 ethylene glycol monoallyl ether, 0.30 g p-hydroxyanisole, 0.26 g antioxidant 1010, 0.7 g p-toluenesulfonic acid, and 154.17 g hexahydrophthalic anhydride in a reaction flask, start stirring, and gradually heat up to 118°C and keep warm. After 2 hours of heat preservation, the measured acid value was lower than 218 mgKOH / g, and the temperature was lowered to discharge to obtain carboxyl group-containing allyl ether monomer D-31.

Abstract

The present application provides a material for three-dimensional forming, a three-dimensional object and a slice layer of the three-dimensional object. The material comprises a powder material and aliquid material, wherein the powder material comprises polyamide powder and / or modified polyamide powder; the liquid material comprises a first active component, and the first active component can besubjected to a polymerization reaction; the first active component dissolves at least part of the polyamide powder and / or the modified polyamide powder, and the powder material itself does not undergoa polymerization reaction and does not undergo a polymerization reaction with the first active component. According to the material for three-dimensional forming, the three-dimensional object and theslice layer of the three-dimensional object, the mechanical strength and density of the three-dimensional object can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of three-dimensional object forming, in particular to materials for three-dimensional forming, three-dimensional objects and sliced ​​layers thereof. Background technique [0002] The existing three-dimensional object additive manufacturing technology includes inkjet printing technology and powder and inkjet printing technology. Among them, inkjet printing technology mainly refers to the selective injection of photosensitive resin materials by the print head on the support platform according to the layer patterning data of three-dimensional objects, also known as printing data, and the radiation source irradiates the injected photosensitive resin materials to form a cured layer. . [0003] In the three-dimensional molding technology using polyamide powder as a powder material, a binder is selectively sprayed on the polyamide powder layer according to the printing data, and the polyamide powder is ...
