Abstract: A electromagnetic wave-induced heating of CNT filled (or coated) polymer composites for enhancing inter-bead diffusive bonding of fused filament fabricated parts. The technique incorporates electromagnetic wave 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 electromagnetic wave irradiation treatment and/or in-situ focused electromagnetic 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.

Abstract: 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.

Abstract translation: CNT填充（或涂覆）聚合物复合材料的微波诱导加热，用于增强熔丝长丝制造部件的珠间扩散接合。 该技术将微波吸收纳米材料（碳纳米管（CNTs））纳入到3D打印机聚合物长丝的表面或整个体积上，以在印刷后的微波辐射处理和/或原位聚焦微波束之后增加珠间粘合强度 。 最终3D印刷部件的总体强度将显着增加，并且熔丝部分的各向同性力学性能将接近或超过常规制造的对应物。
