Seit längerem haben wir das Problem das Orangenhaut an den Teilen auftritt (siehe Bilder). Wir stehen mit dem Support auch seit dem in Kontakt, leider ohne Ergebnis. Nun wäre meine Frag wer diese Problem auch schon hatte und woran es lag oder liegen könnte. Ich bin sehr Dankbar für jede Information zu dem Problem.
For a long time we have had the problem of orange peel appearing on the parts (see pictures). We have been in contact with support since then, unfortunately without results. Now my question would be who has had this problem and what it was or could be. I am very grateful for any information about the problem.
Unfortunately, I don’t have any information on a solution, but I’ve been dealing with orange peel recently. The problem started in early December but did not coincide with a firmware release. The poor finish I’m seeing is not as severe as your examples but is still significant. At the same time, I was getting severe pitting and as a result tuned the bed temperature down 1.5C. This mostly fixed the pitting issue, but the orange peel was still present.
The best guess I have for my problem is degraded powder, but this conflicts with your experience. I think some more information could help others to provide relevant advice.
How long have you had this issue, and does it occur on every print?
Are all the parts in the chamber affected or only some?
Are you printing in Nylon 12?
Have you tuned your bed temperature at all?
I am in the same boat and would be grateful to hear other’s experiences and potential solutions.
(Printing Nylon 12 @ 30% refresh, last two prints @ 50% refresh. -1.5C offset.)
The bed temperature was lowered by -2°C because the powder cake otherwise adheres too firmly to the part. We are printing with Nylon 12 GF, and all parts in the chamber are affected. The orange peel always occurs towards the door and hopper. The problem has been present since around October/November.
Try increasing the print armor in the print editor by 15%, that fixed my problem with the exact same issue. it will make the parts harder to clean but it absolutely works.
I don’t know if this will solve your problem, but I also had problems with orange peel. It was solved with several options. The first cause was already very over-burned and used powder, so you need to increase the amount of virgin powder to 50/70 or 100%. From our observation, stale powder is harder to bake and higher temperatures are needed. We tried to test for some time what would happen if I didn’t use virgin powder at all and we printed only 100% used powder. Orange peel appeared almost always. The only thing we could adjust was the bed temperature, when the print was successful only after increasing the temperature in the chamber by +3 or more degrees. Unfortunately, then it is very difficult to remove the unbaked powder around because it sticks very much to the part, but it is still possible. The unbaked powder is also destroyed even more. Due to the increased temperature, the tolerance of the parts also changed. This was really not a uniform solution. However, it corresponded to our research. This also corresponds to the fact that orange peel occurs closer to the door where the temperature is lower than in the back of the chamber where the heater is located.
Simply put, you can also see it when printing. Orange peel is essentially an analogue of warping in FDM. You can see how the edges of the layer are sintering. That is why this only happens on the bottom layers, not the top ones.
The solution is therefore to increase the temperature - either the chamber or the protective layer or use much more virgin powder. It also helps if you rotate the parts so that their bottom layers are towards the back of the chamber or as close to the center as possible.
The problem is simply constant temperature. We printed in places where we knew that orange peel would appear, just like with FDM printing, in order to locally increase the temperature there.
I had orange peel once, PA12 30% refresh but I usually run a higher refresh due to low used powder. Support suggested keeping parts away from the edges and upping the refresh a bit. Haven’t seen it since and I do sometimes have models up against the wall. If you keep refresh in the 30-35% range, used powder is sintered into the models within 3 print cycles on average if your packing volume is close to matching the refresh rate. If you have a low packing density I can see where used powder would get used over and over and not get sintered.
Das ist ein ausgezeichneter Tipp, den werde ich auf jeden Fall ausprobieren. Darf ich fragen, warum der Wert bei dir so hoch ist? Bei uns war 2100 mW eingestellt, während er bei dir bei 8926 mW liegt?
That’s a great tip, I will definitely try that. May I ask why your value is so high? We had 2100 mW set, but yours is 8926 mW?
