Problems solved by technology

[0002] In 2012, German designer Kai Parthy invented the world's first 3D wood wire Laywoo-D3, which uses wood powder and PLA (polylactide) Made of ingredients, it is a consumable specially used in 3D printers based on the FDM principle. Because the amount of wood powder used is too small, the wire looks more like plastic, but lacks the original feel, appearance, and fragrance of wood, and lacks a lot of wood. Natural processing performance, although PLA has the characteristics of green and environmental protection, but due to the soft and difficult cooling characteristics of PLA, the wire is soft and cools slowly, and the stability is difficult to control, which leads to poor printing properties and low overall quality of molded works , and the wood powder will expand rapidly when heated, and the German Laywoo-D3 wire made of PLA will often block the nozzle when used in domestic 3D printers, so it is only suitable for foreign printers

Embodiment 1

[0042] Using 10% original ecological pine wood powder, 16% ABS plastic, 36% PLA, 35% PHA, 2% PP and 1% cyclic anhydride compatibilizer, the wooden wire made by the following formula The product is off-white, similar to birch, with a relatively smooth surface, and you can see the wood effect on the thread. Concrete preparation steps are as follows:

[0043] ①. Saw the original pine tree into strips, put it into the wood powder crushing and milling machine and grind it into 100-mesh fine wood powder for 3 hours, and then take 10% pine wood powder;

[0044] ② Put the fine wood powder into the wood powder dryer and dry at 80°C for 6 hours to reduce the water content of the wood powder to 0.3%;

[0045] ③. Mix the dried wood powder with the above-mentioned other components, put it into a plastic mixer, and mix it thoroughly for 30 minutes;

[0046] ④. Put the mixed raw materials into the twin-screw granulator together, after heating at a high temperature of 160°C, plasticize and ...

Embodiment 2

[0056] Using 80% original ecological pine wood powder, 4% ABS plastic, 10% PLA, 5% PHA, 0.5% PP and 0.5% cyclic anhydride compatibilizer. The wood filament product produced by this formula is dark brown, similar to the color and roughness of bark, the surface is rough, and has the rough feeling of wood. The printing effect is dark brown close to the bark. Concrete preparation steps are as follows:

[0057] ①. Saw the original pine tree into strips, put it into the wood powder crushing and milling machine and grind it into 100-mesh fine wood powder for 5 hours, and then take 10% pine wood powder;

[0058] ② Put the fine wood powder into the wood powder dryer and dry at 90°C for 5 hours to reduce the water content of the wood powder to 0.5%;

[0059] ③. Mix the dried wood powder with the above-mentioned other components, put it into a plastic mixer, and mix it thoroughly for 30 minutes;

[0060] ④. Put the mixed raw materials into the twin-screw granulator together, after heat...

Embodiment 3

[0070] Using 39% original ecological pine wood flour, 8% ABS plastic, 26% PLA, 25% PHA, 1.5% PP and 0.5% cyclic anhydride compatibilizer. The wooden wire produced by this formula is light brown, similar to the color of milk tea, and the surface texture is relatively rough, which is close to the real wood effect after painting. Concrete preparation steps are as follows:

[0071] ①. Saw the original pine tree into strips, put it into the wood powder crushing and milling machine and grind it into fine wood powder with a size of 90 mesh for 4 hours, and then take 10% pine wood powder;

[0072] ② Put the fine wood powder into the wood powder dryer and dry at 85°C for 5 hours to reduce the water content of the wood powder to 0.2%;

[0073] ③. Mix the dried wood powder with the above-mentioned other components, put it into a plastic mixer, and mix it thoroughly for 30 minutes;

[0074] ④. Put the mixed raw materials into the twin-screw granulator together, after heating at a high t...

Abstract

The invention provides a 3D (three dimensional) wood printing supply which comprises components in percentage by mass as follows: 60%-90% of wood meal, 3%-15% of ABS (acrylonitrile butadiene styrene) plastics, 4%-15% of PLA (poly lactic acid), 2%-10% of PHA (polyhydroxyalkanoate), 1%-2% of PP (polypropylene) and 1%-2% of a compatilizer. The 3D wood printing supply has the characteristics such as water proofing, corrosion resistance, moisture resistance, freeness of worm damage, mildew and toxicity, acid and alkali resistance, environment protection and the like, the real flavor of wood is diffused; the wood printing supply is fused and deposited by a 3D printer at the temperature of 190-230 GDE C to form various different 3D models, the 3D models have the hand feel, the impression and the fragrance of natural wood and have an effect approaching to a solid wood effect and wood properties, and the printing supply can be nailed, drilled, planed, carved, adhered and painted as wood; and the comprehensive physical properties and chemical properties can be well improved and optimized, the performance requirement of the 3D printer can be effectively reduced, and accordingly, the printing supply is suitable for both high-end printers and low and medium-end 3D printers and has a wider application range.

Description

technical field [0001] The invention relates to a 3D printing consumable, in particular to a wooden 3D printing consumable. Background technique [0002] In 2012, German designer Kai Parthy invented the world's first 3D wooden wire Laywoo-D3, which is made of wood powder and PLA (polylactide), and is specially used in 3D printers based on the FDM principle. Due to the low amount of wood powder used, the wire looks more like plastic, but lacks the original feel, appearance, and fragrance of wood, and lacks a lot of natural processing properties of wood. Although PLA has the characteristics of green environmental protection, but Due to the characteristics of PLA being soft and difficult to cool, the wire is soft and cools slowly, and the stability is difficult to control, which leads to poor printing properties and low overall quality of the molded works. Moreover, wood powder will expand rapidly when heated, and it is made of PLA. The German Laywoo-D3 wire used in domestic 3...
