Nice prints after tweaking

Jul 18, 2018

I had to do a lot of parameter tweaking (using Anet A8 and Cura 3.4) , but finally I managed to achieve decent results with this filament.
Most important is that in case of printing fine details, the print speed has to be very low (12.5 mm/s in my case), and even in case of rough prints, the print speed should be kept quite low (below 25mm/s in my case). Otherwise I experience strong underextrusion. Optimal hotend temperature range for me is 210-220 Celsius (and 60-70 Celsius bed temperature). Below that range the layer adhesion gets lower, and above that range the filament melts too much, resulting in less detailed and a bit distorted prints, and stronger stringing. Another key factor is the fan speed set to a low value (20%), because in case of stronger cooling the layer adhesion will suffer. On the other hand, setting the fan speed to 0% is not appropriate as well, as it results in warping (albeit moderate) of overhang sections of the prints. To some extent that warping may be reduced if using a higher bed temperature (80-90 Celsius).
Minimizing oozing and stringing requires a lot of experimenting with this filament. For me the key parameters were maximal travel speed, moderate retraction settings (25mm/s retraction speed, 1.7mm distance), coasting and wiping enabled and set to moderate values.

Unbelievably Good!!!

What they advertise is true: this is a premium filament.
It print almost like PLA (just set your retraction) but a little bit slower, the layer adhesion is really good.
I got this quality, only on brands that are more, than double the price.
Just a little hint: If you, like me, are using Ultrabase as a build plate, set the initial temp. at 80° and the rest at 70°. At 60° Ultrabase might not work properly.
