Maximum Perimeter Speed
Hello everybody,
I am currently printing inserts for board games, to organize all the different tokens and cards.
I experimented with the wall thickness of these inserts for quite some time, and I found that a wall thickness of 0.8mm is perfect. I don't need much filament and the inserts are still strong enough.
Downside is, that the printing speed is quite high, because the models are basically only consisting of perimeters.
Has anyone already experiences with printing speed of perimeters? Maybe a maximum speed, when the quality begins to drop siginifant. Or any other tips?
I am currently printing an Mk2S and have installed the latest firmware. I use the standard "0.2mm, Linear Advance" config of Slic3r.
Thanks!
Re: Maximum Perimeter Speed
Well... it would take more time if the perimeters are the same and you would have infill. Just test speed yourself by adjusting speed during print.
What about the "omg why didn't I notice myself"-solution: Just take 0.8 mm nozzle? However, you then may experience some quality issues because of more retracts (due to every wall now being a single line of extrusion).
But in your case quality should not matter that much. I would give it a try!
Oh and of course you can raise the perimeter height from 0.2 to 0.35 (0.4mm nozzle) or even higher with the 0.8 nozzle.

Thanks for the answer!
So I did some progess on this. First of all I downloaded the new Slic3r beta, which now has an estimated printing time. I did some test print that took 74 minutes, and Slic3r estimated the time to be 71 minutes. So it's quite precise.
Then I tried to print the model I had with .35 mm layer thickness. But the needed filament increased by 40%. It took me some time to figure out, that it has to do with the preset in Slic3r. I took the 0.35mm preset, and it changed quite some other parameters. So I took the .2mm Linear Advance preset and only changed the layer thickness to 0.35mm. The printing time reduced from 124minutes to 74 minutes, while the needed filament got down by 15%. And the results were more than satisfying for my case.
But I didn't want to stop there... Because my models sometimes are quite small (50x30 mm with .8mm wall thickness) I noticed, that the limiting factor was not the perimeter speed or the perimeter acceleration. It was the "minimum layer time." It was set to 20seconds, setting it to 0 reduced the time from originally 124 minutes down to 29 minutes. I wasn't able to test print it yet, but I will inform you about the results.
