Abstract Scope |
Reactive extrusion additive manufacturing (REAM) is a new additive manufacturing method in which a low viscosity thermoset resin is mixed with its curing agent and immediately deposited and cured in situ on the build plate. This method reduces the energy requirements of additive manufacturing by eliminating the need for external heating elements and improving part strength by allowing for crosslinking between layers or individual rasters. Flowrate-dependent passive mixers typically accomplish mixing in REAM, making low volume high-resolution prints particularly difficult. This talk will present active mixing as a modification to REAM, where an external power source mixes the resin and curing agent prior to deposition, removing the flowrate dependency for printing. The primary result of this modification is an improvement to maximum print resolution. This talk will also highlight the effects of processing parameters on part resolution, quality, and thermo-mechanical properties. |
