I use S3D with my UM2+ and it gives much better results than Cura, when all the settings are dialed in right. It looks like that’s probably UM silver PLA, I suggest going to 210c on the temperature, there is some pretty clear overtemp. signs on the print. Try slowing the print speed down a little and experiment with switching off wipe for instance. Last time I printed a Marvin, I used 3,3,3 layers and 15% infill (fast honeycomb)- so a bit less than you, but that’s just to save filament and time, really. Furthermore, just out of habit I always use the heated bed at 60 for PLA, as well as gluestick. This isn’t something that this will make a difference to print quality here, but in case you were looking for other hints and tips. I’ve found 50 to be a bit low and especially larger prints will want both the heat and glue, at least on my machine. To be honest, those are not bad looking prints, and with a little tweaking, you’ll get those settings dialed in just right.
Dont give up on the filament you were using. Pretty much all guidance on PLA is going to state a range like that…and there are times when you might use it. Like a go fast print with a big nozzle.
Definitely worth using better quality filament! You paid a good bit of money for the machine, don’t start being tight when it comes to filament, or you will get to spend even more fixing issues that the poor quality filament causes… When you consider near 100% success rate with a higher quality filament vs something as low as 70% with cheap stuff, you will probably save money pretty fast.
I consider “Das Filament” Filament to be very good quality, quite sturdy for PLA from my experience. I wasn’t pleased with the Verbatim brand black PLA i got initially.
As most of the guys are saying, your Nozzle temperature is a bit on the high side, if your using a standard brass nozzle you should be at about 200-205’C if your using a Ruby Nozzle, add about 5’C.
slow the print speed down a little, 40-45mm/s.
it also looks like you are using the std fan duct, as you have uneven cooling on the two sides, noticeable about the ears and the eyes, several of us have designed improved ducts that improve the cooling fan flow balancing it to both sides, check them out on YouMagine and give them a try. This should help with the uneven cooling, although as some are very effective you will need to reduce the fan speed a little, ?
The top loop is a cooling problem, too much heat and dwell time can cause problems, but yours isn’t too bad, I’ve see worse.
you could always create a small file to play with the top and the loop that only takes 5 minutes to print and then play with the settings as swordriff mentioned.
good luck, Izzy
My experience is completely different about Cura vs. Simplify 3D quality of prints. Probably because you always need to make perfect fit settings to object
Bonjour,
Pour moi la température est trop élevée
Température : 195°C voir 200 °C
Vitesse d’impression 50 mm/s
Ventilation : 100%
