摘要： A process of imbibition drawing is improved by a pretreatment that preferably involves straining an undrawn filament bundle, or other elongated shaped undrawn or partially drawn synthetic polymeric article, while wetted with a cracking agent, before incorporating a desired additive by imbibition drawing, thereby increasing the imbibition capacity of the article, and improved articles incorporating such additives. Alternatively or in addition the pretreatment involves polarizing irradiation, before imbibition drawing.
摘要翻译：通过预处理改善浸渍过程，该预处理优选包括在通过浸渍拉伸加入所需添加剂之前，用未裂化的长丝束或其它细长形未拉伸或部分拉伸的合成聚合物制品同时用裂化剂润湿，从而增加制品的吸收能力，以及掺入这些添加剂的改进制品。或者或另外，预处理涉及偏振照射，在吸液之前。

摘要： A microwave-induced heating of CNT filled (or coated) polymer composites for enhancing inter-bead diffusive bonding of fused filament fabricated parts. The technique incorporates microwave absorbing nanomaterials (carbon nanotubes (CNTs)) onto the surface or throughout the volume of 3D printer polymer filament to increase the inter-bead bond strength following a post microwave irradiation treatment and/or in-situ focused microwave beam during printing. The overall strength of the final 3D printed part will be dramatically increased and the isotropic mechanical properties of fused filament part will approach or exceed conventionally manufactured counterparts.
