Thanks for reply Sticking to regular filaments is a no go 😁 This is a hot seller. I was thinking in the same direction, i tried retract at layer change, but no difference. Next time i will try to decrease the distance, i keep you posted

The viber statues we print have zits/blobs on the surface. It seems like its the transition from the support to the wall surface. On the last photo you also see the stringing from the support to the outer wall. Is this an overextrusion problem? How we can improve this? Printer: UM S3 software CURA 5.6.0 material: VIBERS Colorfabb nozzle: 0.6AA layer height: 0.12 print temp: 200 bed temp: 20 flow: 103 Print speeds + infill: 50 print speeds all wall speeds: 30

It's really hard to describe what the problem is, but the pictures speaks for themself. Where the supports are, the surface of the print is very bad. It's shited, molten,.. The arm adbove has very bad lines, it looks like the arm of the statue is moved/shifted. Can anybody help me? Could it be a envirmental issue, temperature?

This was it, the ambiant temperature. It's cooler now and we are printing perfect statues now So thanks everyone for the input!

Thank you for this input. I feel like i owe you a drink! We are making good statues now. Heated bed off All speeds at 25mm Flow 105% The last print we had a weird thing, the print is super smooth, but we have lines and underextrusion at top of the print. Is this random? Or can this be fixed? It was very hot yesterday 35+°C where we are printing. Could this be it. Thanks again

With the 0.6 we are printing and the error doesn't occur. But there is some underextrusion. See photo below. UMS3(photo) We did the test printing at 195° and flow 100% Wall speed 30 Infill speed 45 Retraction distance 4.5 and speed 30 The Tower thing wint help because the underextrusion is only after few hours. We alsof notice that the infill the lines from left onder to upper right are good. And from right under to upper left are bad. How?? I don't think this is better, what can we try to improve this?

Thanks for the reply. I think it's an environmental issue. Atm we are printing good statues again. I put a fan on the back, that targets the feeder, the filament and the back of the printer. Changed the nozzle from 0.4 to 0.6cc. with the same settings (ofcourse changed for the 0.6 rest remains) Filament in dryer before usage. We are printing on 200°C When i increase the temp to 210°C the result is worse. Isn't this weird? Because the higher the temp, the better the flow?

Thanks for the reply. No the sensor is still on. Because the error is a thing, but the quality is not good. So om glad that it stops, because it's wasting material. Even so bad, that it just keeps printing in the air. The printer 'stops' extruding material.

Thanks for the reply We notices that the filemant did not 'crack' as fast as it used to. It bended more before it broke. So we put the roll in a filament dryer, the humidity was to high. From now on we put each bronzefill roll in the dryer before usage.

hi Gr5, thanks for the reply. we test this on different printers (2), and different heads (4). With cleaned cores 0.4 Both AA and CC, new cores 0.4,... The material error keeps popping up. it occours after few hours, few minutes, its weird You got some more tips/ things we can try? We are running no production on the bronzefill atm, PLA works fine. Is there a posibility that you might send me a profile you use for metallfill/bronzefill filament printing? thanks

Hi slashee, thanks for the reply. i followed your advice, no ventilater in the front of the printer, but i put it on the back. Where the feeder and the filament is. This was better, before, the filament was flatted by the feeder. Diameter of the filament was at this point 3.12mm. So to big to fit through the bowden tube. We notice that the bronzefill filament got soft. Normaly it breaks easier. With the dryer, and the ventilator on the back, its fixed. But the problem still remains. On both printers, on both printer heads/feeders. Different/ new cores installed. it occours after few hours, few minutes, its weird You got some more tips/ things we can try? We are running no production on the bronzefill atm, PLA works fine. Is there a posibility that you might send me a profile you use for metallfill/bronzefill filament printing?

Hi, thanks for taking the time to reply. Yes on both printers. The filament was flattend by the feeder, not grinded. We notice that this problems comes when we increase the flow. With normal flow, and filament out of the dryer, this problem is fixed. but anyways, we are no making any production atm. Same problem over and over. Sometimes after 3-4 hours, sometimes after 10 mins, 30 mins,... We notice that when we increase the temp from 200 to 210, the errors comes quicker.

The flow is 104% Temperature now 210 But could it be the heat in the printer? I already placed a ventilator on the printer with the door open. The wall is fine, but the infill is messed up. The first 2 hours of the print the infill is great.
