Shanghai Daoqin Plastics Co., Ltd.

近 day, 随 万华 launch PP powder material WANFAB® PP700N, PP will 进入一 full new application areas —— 3D printing.

3D printing technology also increase manufacturing technology, is 一项起源于20 世纪80 year machine 械, machine, and material 于一体 先进 manufacturing technology.

该 technology basic principle is according to 三维实体 parts sheet/slice obtain 二维截面信息, 以点, or as is basic mono 元进行逐层堆积 manufacturing, most obtain parts or type.

versus ratio 于传统 decrease 材(如切削 processing) and and other 材(如锻造) manufacturing methods, can achieve methods method or very difficult to complex structure parts manufacturing, large decrease/reduce processing 工序, shrink short processing cycle, remove material 浪费, in has mold and tool lower speed manufacturing 出形状 complex 三维实体 parts.

3D printing 3 key/critical elements:

1. product need 精准 三维 design, use machine design （CAD）工 tool for product full 方位精准定位.

2. strong/high large molding equipment.

3. need meet/satisfy products property can and molding process material.

currently 3D printing material main/primary resin plastics most is formed 熟, also method full meet/satisfy high industrial 3D printing need, therefore need has plastics material 不断完善 and 改进. plastics material tool has thermoplastic property can melt features, in melt lower, from 喷头处挤 pressure 出, through solid 层层叠 add most formed product.

due to plastics material good hot flow property, fast speed cooling bonding property, relatively high machine strong/high degree, in 3D printing manufacturing field/area to fast speed application and development. plastics material melt adhesion features will resin plastics used for 陶瓷, 玻璃, machine 凝胶, fiber, metal and other, formed is 3D printing 基础材 material.

3D printing technology can through multiple process achieve, 包括熔 melt molding （FDM）, selection property light 烧结（SLS）, outer UV curable molding （SLA） and other. its in, SLS tool has molding degree high, 无需添 add structure and powder can recycling utilizing advantages, in manufacturing field/area already has non 常广泛 application. in recent years separation 火爆 3D printing 跑鞋, its structure design shoe sole is use SLS technology printing made formed, not only can combined 穿 者脚 type, also can through shoe sole structure obtain has 穿 体验, or elastic force high, or hard has thick 实感, this is SLS technology excellent property 体现.

WANFAB® PP700N using/adopting 万华定 made development material formulation, in SLS printing process in can has solution warpage deformation issues, printing degree high; products fracture elongation can 达20%, tough property relatively good. in addition, additives combined make PP powder tool has color heat stabilized property, can more recycling use, large large reduce printing cost.

according to Wohlers statistics, 经 近十 year high speed development, 2017 year full 球 3D printing market 规模达 to 73 100 million USD, IDC forecast 2020 year full value will 达289 100 million USD. can future year, full increase manufacturing industry still will high speed growth 期, development force large.

due to 3D printing manufacturing technology full 改变 传统 manufacturing industrial methods and principle, is for manufacturing 模式 一 types 颠覆, therefore 3D printing material formed is made 3D printing development main/primary bottle 颈, is 3D printing breakthrough innovation key/critical and difficulty/challenge in, has more more new material development can 拓展 3D printing technology application areas.

随 3D printing technology 进一步 development, plastics property can will by large improves, plastics strong/high large fast speed melt and low temperature bonding features will by application to 3D printing manufacturing field/area.

for/regarding polyolefin material 说, this field/area can 错. most new launch PP powder material —— WANFAB® PP700N can is 开 一 good 头, remove outer, also for different 3D printing process launch series material solutions: WANFAB-FT（TPU线材）, WANFAB-PU（TPU powder 末）, WANFAB-PN（ nylon powder 末）, WANFAB-UV（ light resin ）, WANFAB-PP（PP powder 末） and other.

versus in 3D printing lower, will has more more polyolefin production enterprise this field/area, R&D, production combined 3D printing requirements product, this will 助推我国 in high polyolefin field/area development.
