Hello everyone
As we prepared a composite in filament format and print a sample, how could we control the distribution of reinforcement non-continuous fiber or particle on the deposited layer path?
Best regards.
Hi Milad. I think you are referring to composites from filament, but in terms of deposition of mixtures in a fluid matrix (in this case, cementitious mixture) I recommend this article https://www.sciencedirect.com/science/article/pii/S0958946516301093
(The orientation in the filament itself is important to consider before final deposition). Greetings.
Dear Víctor Martínez Pacheco
Thank you for your contribution, yes. I mean the filament composites. when we produce a filament by adding non-continuous fibers or particles, by melting filament in the heat zone of the nozzle head of the 3d printing machine the additive materials change their positions in the solid filament. Hence the additive materials don't have a uniform distribution in the deposited layer. Therefore I'm looking for a way to achieve good distribution in the deposited layer. Yet no success was achieved.
Hi Milad. I think what you can do is on the design side of the model. You can write the G-codes with your aimed printed paths and directions, or design a CAD model with discrete printed orientations with tiny spacing. You can't really control the fiber distribution within the filament, and the distribution inside the filament will change anyway when the filament is printed.
Dear Kaiyue Deng
Thank you for your contribution. I'll try that.
Best regards.
