<![CDATA[SoliForum - 3D Printing Community — Increasing print quality by decreasing filament diameter?]]> 2014-03-16T19:41:30Z PunBB https://www.soliforum.com/topic/5850/increasing-print-quality-by-decreasing-filament-diameter/ <![CDATA[Re: Increasing print quality by decreasing filament diameter?]]> As a conceptual idea, there are benefits to the 3D printing world moving to maybe 1mm or something else smaller than 1.75mm. If it becomes large enough that all filament wire is custom anyway, the cost increases might be negligible. It would require more care to avoid buckling of the filament as you feed it through the processes, though.

But, anyway, 1mm filament is easily to through through a 0.3mm nozzle than 1.75mm filament, because the constriction backpressure pressure is related to the third or fourth power (I'm not sure which.)

Elmoret might have more ideas and better understanding of whether it could be beneficial for 3D printers to move towards thinner filament.

one downside that comes to mind is this: greater surface area to volume equals more care needed to prevent water being soaked by hydrophillic filament (is Hydrophobic the right term? I mean, for example, Nylon.)

This effect is quite noticeable when comparing filament thats say 1.7 diameter +-.05 with 1.55 diameter +-.05 .  I would not have thought that would make a very large difference
