Development of PLA/CNTs nanocomposites for multifunctional 3D printing applications

三维打印(3D-Print，3-DP)作为一种加法制造工艺，已经引起了世界各国的极大兴趣。随着3D打印对于个人来说变得越来越容易和负担得起，工业界和学术界都在关注当前3D打印技术的能力和应用。对于FFF(熔丝制造)3D打印，所使用的打印材料，即长丝，大多限于少数热塑性材料。因此，印刷结构或装置通常不起作用或缺乏所需的性能，例如机械强度、导热性和/或导电性。预计，与目前的文本和图形打印市场一样，3D打印市场的最大份额将很快成为打印消耗品。为了拓宽3D打印的应用范围，开发新的3D打印材料势在必行。

Three-dimensional printing (3D-printing, 3-DP) is an additive manufacturing process has attracted tremendous interest from the world. As 3D printing becomes more and more approachable and affordable for individuals, both industry and academia are concerning with the capability and applications of current 3D printing technology. For FFF (Fused Filament Fabrication) 3D printing, the printing materials, i.e. filaments, being used are most limited to a few thermalplastic materials. Therefore, the printed structures or devices are often not functional or lacking of desired properties, like mechanical strength, thermal and/or electrical conductivity. It is expected that, like the current market for text and graphics printing, the largest share of the 3D printing market will quickly become the printing consumables. It is imperative to develop new 3D printing materials to broaden the range of applications of 3D printing.
