阅读说明：本技术 用于3d打印的非实心纤丝 (Non-solid filaments for 3D printing ) 是由 A·瓦奥拉 J·J·亨利 D·S-R·刘 于 2018-12-27 设计创作，主要内容包括：本发明涉及用于3D打印的热塑性纤丝,其中,纤丝的芯部是非实心或单纤丝。纤丝可以包含大量的小微孔隙(微泡沫),是泡沫芯结构,是中空的,或者具有单纤丝芯。本发明的纤丝特别适用于结晶和半结晶聚合物,并且减少了由纤丝冷却期间由收缩形成的纤丝孔隙的负面影响。(The present invention relates to thermoplastic filaments for 3D printing, wherein the core of the filament is non-solid or monofilament. The filaments may comprise a large number of small micropores (microfoam), be of foam core construction, be hollow, or have a monofilament core. The filaments of the present invention are particularly useful for crystalline and semi-crystalline polymers and reduce the negative effects of filament porosity formed by shrinkage during cooling of the filaments.)
