Embodiment Construction

[0017] The present invention is further described by the following examples.

[0018] The invention provides a modified ABS bamboo consumable for 3D printing, which is specifically realized through the following technical scheme: the formula of ABS-based modified bamboo 3D printing consumable is as follows, bamboo fiber 10%-22%, ABS plastic 60%- 77%, coupling agent 1%-2%, hollow microsphere 0.5%-1%, lubricant 0.5%-1%, antioxidant 1%-2%, toughening agent 2%-2.5%, plasticizer 5 %-9.3%, compatibilizer 1%-2%. After the above raw materials are blended, they are granulated by a twin-screw extruder, and the granules are made into filaments with a diameter of 1.75±0.05mm by a 3D printing consumable extruder.

[0019] In each link, the specific parameters are as follows:

[0020] Bamboo fiber is bamboo fiber made from natural clustered bamboo. The purity of the above-mentioned ABS plastic is above 99%, and it is used after being dried.

[0021] The coupling agent is one or more of s...

Abstract

The invention discloses a modified ABS bamboo consumable for 3D printing. The consumable is prepared from the following raw materials in percentage by weight: 10 to 22 percent of bamboo fiber, 60 to 77 percent of ABS plastic, 1 to 2 percent of coupling agent, 0.5 to 1 percent of hollow microsphere, 0.5 to 1 percent of lubricant, 1 to 2 percent of antioxidant, 2 to 2.5 percent of toughening agent, 5 to 9.3 percent of plasticizer, and 1 to 2 percent of compatilizer. The raw materials are co-blended and granulated through a dual-screw extruder, and particles are prepared into wires which are 1.75+ / -0.05mm in diameters through a 3D printing consumable extruder. The prepared 3D printing consumable is applied to a 3D printing fused deposition technology, an obtained model has the fragrance and hand feel of natural bamboo and can be enhanced by 5 to 20 percent in strength, edge warping is prevented during printing, and a 3D printed workpiece has higher quality.

Description

technical field [0001] The invention relates to a 3D printing consumable, in particular to an ABS-based modified bamboo 3D printing consumable. Background technique [0002] 3D printing, also known as additive manufacturing, is an advanced manufacturing technology that has been developed through the integration of information technology, new material technology and manufacturing technology in the past two decades. Fused deposition modeling (FDM) is one of the common processing methods of 3D printing. It is fed with thermoplastic filaments and printed out by layer-by-layer superimposition. ABS plastic has good mechanical properties and excellent formability, making it one of the most widely used printing consumables in FDM. However, ABS consumables also have the disadvantages of pungent smell during printing, low glass transition temperature, high brittleness, poor thermal stability, single function, and high price. Therefore, it is very important to modify the ABS consumab...
