Shanghai Daoqin Plastics Co., Ltd.

new type 冠状病毒感染 肺炎病魔席卷 full 国, for its 疫情, in large resistant 击, full 国各 医护人员驰援湖北. is 抵御病毒 侵袭, 医护人员严密 anti 护, is due to long time as 业, many 医护人员 面部 by anti use tool loss 伤. this 一抹抹印记, is 他们无私奉献 军功章, 却也牵动 full 国人民 心.

图1 一线医务人员 面部 loss 伤

一, this is how to generate 呢?

its causes, is 护目镜 and 佩戴者 面部 structure combined!

佩戴护目镜 is 抵御病毒 through 眼睛传播 has 效途径. 医护人员 is ensure property, 往往勒 comparison 紧, make 护目镜边角处 棱 and 面部贴 combined generate relatively large pressure and scratch force. 随 工 as time growth, pressure generate 疼痛, 麻木, pressure 红, pressure 痕, 甚至破 loss and other pressure property loss 伤, heavy 者出现发炎症状, large effect/influence 护目镜 use 体验, 危害医护人员 健康.

护目镜 main/primary used for 运动, machine processing, 实验, and other anti 止眼睛 by material product, chemical product, property liquid （如飞沫, liquid and other ）伤害 anti 护眼镜, generally separation is anti solid 体碎屑 type and anti chemical solvent liquid type. for new 冠肺炎, 护目镜 main/primary function is anti 止喷溅 property 传染源 and gas in 病原体进入眼部. types anti 护眼镜都 can selection, in different use scope/range. anti chemical solvent liquid anti 护眼镜因 is tool has good full anti 护, can used for 病原体 density relatively large 临床, 实验室 and other ring 境, suitable for ring 境; anti solid impact 护目镜仅 suitable for gas in 病原体 density small, can can in property liquid ring 境.

二, made 化护目镜 is what?

solution 护目镜 and 佩戴者面部 structure combined issues 就需进行护目镜 定 made 化.

现 has medical grade 护目镜由镜架 and 镜臂两部 separation formed, Raw Materials is polycarbonate (PC) and other has machine polymer/macromolecule material, through injection molding machine high temperature rear, fast speed mold, cooling rear formed. due to made as mold need relatively large cost and relatively long cycle, production 者往往会 solid mold, heavy use large amount production, made as 出 护目镜 is full 一样, specifications mono 一.

图2北京 chemical industry large 学英蓝实验室 made as 护目镜

due to different 人 脸部 structure different, same large small 护目镜就会出现不 combined 适 情况, therefore generate upper 述困扰. in already has very more 科技工 as 者提出 各式各样 decrease measures, need from upper solution issues, from improvement structure 入手, is 每名医护人员" amount 体裁衣", made combined 人面部特征 护目镜, especially is made 护目镜 密封 strip/profile, that will is most solutions.

can to 吗? is can!

三, how to achieve? —— flexible 3D printing /复印 made technology

utilizing 三维扫描, flexible 3D printing /复印 made technology can achieve 护目镜密封 strip/profile made 化. specific technology 路线如 lower types:

图3 定 made 化护目镜 made as process/workflow

specific steps is:

①三维扫描: utilizing "三维扫描仪" for 佩戴者 面部轮廓进行扫描, process 需1 separation 钟, can in short inner speed a large amount of data.

②建立模 type: using/adopting 三维建模 soft parts, according to to data, combined standards frame dimensions, formed 密封橡胶 strip/profile 三维模 type.

③ molding strip/profile: due to strip/profile using/adopting soft/flexible TPU or silicon made formed, using/adopting flexible material specialized 3Ｄ printing equipment or printing hard mold again formed 形 3D复印 technology made as; chemical industry large 学英蓝实验室发明 melt micro separation 3D printing can full flexible material 3D printing molding.

④ made as formed product: will made 化 密封 strip/profile replace 原护目镜密封 strip/profile, can to 密封效果 good, 舒适感 strong/high 护目镜, from achieve 护目镜 定 made 化.

lower 面, small is large 家讲讲 melt micro separation 3D printing technology and 3D复印 technology.

melt micro separation 3D printing technology

melt micro separation 3D printing technology principle 如图5 示, innovation using/adopting precision screw material material and material principle, fast speed 响应 开关阀式 material control methods and melt pressure ring balanced and other key/critical technology, can achieve various material 粒状形态直接 printing molding, solution has melt 沉积 3D printing for consumption types type and consumption 材形态存 in made technology difficult 题, consumption types type 广, cost low. positive 因如此, flexible material as is product raw materials strip/profile made as formed 功. meanwhile, will this type of equipment 形象 称 is "不挑食 3D printing machine ". 图6 示 is melt micro separation 3D printing equipment can 适应 材 material and for sample type.

图6 melt micro separation 3D printing equipment can 适应 材 material and sample type

3D复印 technology

"3D复印"由北京 chemical industry large 学英蓝实验室学科 belt/tape 头人, 教育部 long 江学者特聘教授杨卫民教授提出, is 以模塑 molding is core 智 can manufacturing technology, through 扫描, 3D printing made 模, molding 一体化 智 can system 构建, achieve tool has complex structure parts amount fast speed made.

图7 实验室 positive in using/adopting 3D复印 technology production 护目镜

至此, made 化护目镜就 made as 出. again use 担心医护人员受伤啦!

疫情发生以, 英蓝实验室坚持科研攻关, 始终奋战 in resistant 击疫情 front 沿. 实验室 utilizing 3D printing /复印 technology, manufacturing production belt/tape light sheet/plate type 护目镜5000余副, separation 2 batch 送抵一线, is 湖北武汉, and other more resistant 疫一线 ring 卫工人 provide and has 效 健康 anti 护, meanwhile also to more 家三甲医院 and ring group, in ring and other mono 位.
