I’m getting a weird issue with ironing on my A1 printer with hardened hotend. On some pieces, the ironing is really globby and inconsistent, but most pieces it looks great. I’ve attached a photo, the left one is the messed up one and the right one is the good one. I’ve also attached a photo of the print bed, where I’ve circled all the ones that are messed up in the same way. The 3mf file should include have my settings as a preset inside the project, let me know if I uploaded it wrong.
The filament that’s having issues is CC3D red silk PLA.
Additional detail: I was actually getting this issue with the inner clear filament (AMOLEN glow) in the past, but I just turned off ironing for it. For the silk, the ironing makes it look way better so that’s not an option.
My guess is that maybe there are some bubbles in the filament or something? But I really don’t know, so any thoughts or ideas would be appreciated. Thanks!
I didn’t dry it, but it is new filament and I live in Arizona where it’s really dry. I haven’t heard filament popping when printing either, or had it splatter
Silk & Glow usually have to be 5* hotter that PLA, so say 215-220*
Hardened nozzle is also usually 5* hotter.
So I would increase the hotend temp to 225-230*
You could try switching from Arachne to classic+thin wall detection and see if the result is acceptable. The ant legs have some sudden thickness changes. Also if you don’t have success with increasing temps, decrease them. The puffing effect of silk pla can cause problems at too-high temps.
Both clamps printed with the same G-Code file. The first picture shows bubbles formed by boiling water.
Where you are living does not matter in case of new filament. It was produced somewhere else where you might have a higher humidity. Based on my experience many manufacturers don’t dry their filament properly before packing and shipping it.
The first step before printing with new filament should always be to dry it with a filament-dryer (or something similar) until you can be sure it is really dry (hygrometer shows something between 8% and 9%RH). The drying process can take quite a while depending on the humidity of the filament. This way you can rule out “wet” filament as source of printing problems.
Where you live is responsible for how fast the filament gets “wet” again.
