polypropylene (PP) （PP） its is day active in most Common polymer 之一. it tool semi transparent 效果, and for chemical material and fatigue resistant property non good; again add upper due to food and micro safety, usually used for use plastics container.

而应 used for 3D printing, PP non combined use made as light 便, anti water or resistant use material product. 例如铰链代 table/sheet types non 常普遍 applications, is PP can bending 而不会 fracture. PP color resistant property make its formed is 吸引人 材 material, 但众 周知, it used for 3D printing very difficult 处理. let 我们看一 lower this type of material 挑战, and solution this 挑战 几 types methods.

polypropylene (PP) material main/primary issues is it viscous property good. although this for/regarding certain processing methods can can very good, for/regarding 3D printing process is that good. this make printing parts very difficult in printing upper, from 而导致 frequency fault/failure.

另一 挑战 is polypropylene (PP) tool has semi crystallization structure. in 3D printing process in, this 意味 会 generate high warpage force, from 而导致 viscous to printing upper 第一层整 脱离. due to printing 床 附 force and warpage is 我们面临 main/primary issues, therefore this is industry inner solution 挑战以 formed use polypropylene (PP) 进行 3D printing.

1 will transparent packaging belt/tape viscous to printing upper

tape by used as printing upper bonding additives, Kapton tape and color 3M tape is commonly used selection. is, this 经典选项 in in use PP材 material method very good function, is PP for various material viscous property 都不太 good.

幸运 is large more transparent packaging belt/tape is polypropylene (PP) made formed. therefore this is types 反常识, can in transparent packaging tape upper printing, although this type of tape surface comparison light slip, can make same PP材 material more easy viscous in upper 面.

2 use relatively large sheet/plate

is resistant polypropylene (PP) high warpage force, use relatively large sheet/plate, this increase printing 第一层 surface 积, decrease/reduce warpage force in increase printing formed can can property. printing formed rear need 剥离掉即 can, for type outer surface 几乎没 has effect/influence. use PP时, can can must increase sheet/plate large small make its ultra- 出 its it material 情况.

3 调 high hot temperature degree

decrease light warpage types methods is improve/increase temperature. this can anti 止PP drop temperature more, from decrease/reduce shrinkage amount. through decrease small shrinkage, can decrease/reduce generate warpage force amount. 一 不错 起点 is printing machine or consumption filament manufacturing PP默认设置, if has recommendation 配置 话. 否则请 from 85°C开始, will hot 床逐渐调 high 5°C, to to most temperature degree ——应该 in 85至100°C between.

封闭 3D printing machine maintain hot amount anti temperature degree 波动也 can can is has 益, if obtain relatively good 3D printing 效果, that can 尝试自己动手 made as 3D printing machine outer 罩, 例如亚克 force material.

due to PP材 material in 3D printing application in that Common, therefore comparison difficult to formed solutions; is Raw Materials PP本身却 is application most plastics 之一, therefore need in printing process in more 做尝试, has can can obtain printing 效果.
