Question about printing times (www.thingiverse.com)

submitted 6 months ago by skotimusj to c/3dprinting

19 comments fedilink hide all child comments

Hello all. I am very new to this but it is all very cool to me. I ran into a problem and I am not sure how to troubleshoot it. I downloaded a simple pull string helicopter off thingiverse. After running through the slicer software, the estimated build time is 131 hours. Relative to it’s size this seems insane. If I “run the simulated build”, there are long holds on one of the interior walls. I am hesitant to just “try it” and see if the pauses are a software thing that does not translate to the hardware. I am not sure how to break it down from here. Any advice?

I suspect what's getting you is minimum layer time. In a nutshell, extruding very hot plastic onto a layer that was very recently extruded can result in a runny mess. Minimum layer time is intended to address this.

That said 131 hours seems a bit intense.

What's your layer height? How good is your cooling? If you crank your fan, you might be able to decrease minimum layer time.

Layer height is 0.1mm. it's odd, because it happens on specific curved areas. There are no pauses on other areas that were recently printed.

You mean travel speed is slower in those curved areas? Perhaps it's due to an overhang.
