Evaluation of the Effect of Plasma Treatment Frequency on the Activation of Polymer Particles

Enhancing the mechanical performance of additive manufactured polymer components using atmospheric plasma pre‐treatments

“…The barrel reactor which has previously been described, is shown schematically in Figure . It consists of a quartz chamber with effective treatment dimensions of 10 cm length and 10 cm diameter.…”

“…This study reports the performance of barrel atmospheric plasma system for the pre‐treatment of both ABS and PLA polymer particles prior to filament formation. The effectiveness of the barrel plasmas for the pre‐treatment of powders has previously been reported . In this study the effect of systematically altering the atmospheric plasma treatment conditions on the level of polymer particle activation is investigated.…”

Plasma treatment of polymer powders – from laboratory research to industrial application

“…An inner wire HV electrode (B) is another co‐axial approach . Also, arrangements with shell type (C) or parallel electrodes (D) are applied, as well as external bar electrodes, which rotate a dielectric tube (E) . A unique configuration are multichannel DBDs providing a central afterglow treatment zone (F) .…”

“…(D) Rectangular cross‐section with parallel electrodes . (E) Rotating dielectric tube with external electrode bars . (F) Multichannel configuration with plasma afterglow directed toward a center treatment zone…”

“…Process conditions: 130 kHz, 240 V, 10 slm He/0.02 slm O 2 . The inserted images illustrate the surface roughness of the particles) (data adapted from Abourayana et al)…”
