Utilizing smaller extrusion widths (Than nozzle diameter) is a fantastic way to increase print speeds while maintaining quality.
This is a reassuring post.
I always print my 1st layer at about half the nozzle diameter this seriously improves adhesion to the bed.
i remember jagowilson suggesting the same.
But I tried 0.2 mm thickness for first layer, and it doesn't stick to the bed at all.
Are you maybe squishing it also quite a bit?
This is interesting, any ideas why this improves adhesion? I've been having serious adhesion problems lately (everything I print warps).
Of course there is support which can be a difficult one to dial in but can dramatically improve removal if done correctly.
I didn't quite get what you mean.
Take some time and play around with the numbers to see the different impact.
I guess this means it's safe to play around with the numbers.
Okay, so this is what I tried.
Printed rectangles and circular buttons only so far, no overhangs or complex shapes.
Okay, so with 0.2mm layer height, 0.2mm External perimeter width and 0.2mm top solid infill I got a pretty good rectangle. The top is like it wasn't 3d printed. It's not 100% smooth either, there's a tiny bit of texture to it, but I couldn't see the lines
Same with setting the values to 0.1 mm.
Then I went ahead and tried 0.05 mm just out of curiosity. I got some smearing of the plastic in places and in places the plastic had brown spots. I think a sign of over extrusion and plastic burning by contacting the hot nozzle too much or the z motor not moving the bed down enough for each or some layers.
My hotend temp is 215C.
I'll post photos when I find lens for macro photos. These details are really small for my camera.
In general the results are pretty satisfactory so far. Thanks everyone for the input.
One question I have now, is there a point in me getting a 0.2mm nozzle if a 0.4mm nozzle can do 0.2mm already?
