Abstract Scope |
Volumetric additive manufacturing of composites is an emerging manufacturing area for producing composites with complex geometries and multi-functional properties, with potential to revolutionise sustainable manufacturing. However, one of the primary hurdles is achieving a time/cost-effective process capable of control over material properties, geometric features and reinforcement distribution in advanced polymer composites. AM process is basically a layer-by-layer manufacturing posing substantial runtime with potential defect inducing between layers, thus is not well-suited for mass production and requires post-process consolidation.
The current research studies the adaptive character of a thermoplastic composite AM equipped with magnetic fields to achieve accelerated composites' geometric tailoring and field induced reinforcement adjustment in a FDM-based process (targeting 10 times faster production than conventional AMs). A controlled magnetic field equipped filament-based 3D printing rig has been setup, capable of altering the magnetic strength, orientation, and distance relative to the processed composite as the process kinetics is undertaken at the nozzle and platform temperatures of 220°C and 60°C, respectively. Room-temperature consolidating thermoplastics (e.g. PLA) reinforced with nearly 10% Vol. iron microparticles (average 10 micron size according to our X-ray computed tomography measurement) have been examined in laboratory-scale multiple specimens within 30x30x30 cm3 space. The real-time kinematics of the mechanical deformation during the proposed process have been measured via instrumenting the rig with optical, thermal and magnetic measurements. The correlation of the process parameters with the experimental observations is conducted to understand the process induced deficiencies, e.g. reinforcement dynamics, layers separation, and improvements, in situ during such magnetic assisted AM. |
