As we continue our exploration of ways to minimize stringing, let's remember that after several iterations of testing, it was a setting of 250 microns and medium infill density that has risen to the top so far. Here is the image of the print output with those settings.
|250 Microns / Medium Density|
|200 Microns / Medium infill|
There is some stringing between the top and adjacent petals. But, for the most part, it's pretty clean. Zooming in on the image some small blemishes can be seen, in the areas of greatest bulk, where the filament, while not creating a full string, pulled up a bit before cooling. So, what of the Low Infill?
|200 Microns / Low Infill|
So, let's turn our attention to a setting of 200 Microns / High Infill density.
|200 Micron / High Density|
So far, the top candidate is still 250 Microns / Medium density.
Perhaps it is because 200 Micron layers add more total density, and thus more heat retention, regardless of the infill setting. Frankly, I'm finding these results quite counter-intuitive because in the past I have only focused on layer height with no regard for density or heat retention. But, the software that runs the M3D Micro gives me much greater latitude over both layer and infill density than I have had with the clients of the other 3D printers I've used in the past.
I like that. I like it a LOT!
In the next installment, of this series, we'll examine 150 Microns and finally in the last of these tests, 50 microns.
But, before then, I would like to share with you my tests of 'stickiness', as affected by gap height, using Antique Gold filament. So, that will be my next article. Very cool!
