Holes in Print
Hello, i have a Problem with my new Filament: on my Benchy i have some small holes in it (see picture attatched). I used Prusa Slicer 210degree Celsius for first layer and 205 for the others, bed temperatur 60 degrees, room is very cold (only 12 degree Celsius). I set the seam to random.
I am pretty new to 3D printing, maybe someone could help me out.
is there a Problem with the Settings or with my printer?
thanks
This is often a symptom of damp filament, usually accompanied by fine stringing. Do you hear popping and fizzing from the extruder?
Cheerio,
RE: Holes in Print
Thanks for the reply. Hm i will listen to that today, it is new filament, out of the box so this would be a bit strange 🤔
RE:
Not really. Just because a filament comes fresh out of the box doesn't necessarily mean it's been properly dried by the manufacturer.
RE: Holes in Print
Ok thanks, i am going to try to dry the filament. But could this also be a setting in the slicer for example something with the seam?
RE: Holes in Print
What's your setting for the seam? If it is "random" or "nearest", try setting it to "aligned".
RE: Holes in Print
Ok thanks, i used "random". I will try the setting "aligned" today.

I found my mistake, the filament is silk filament and expands/foams after the extrusion. I have never printed such a filament before and I think i need to dial in the settings a bit for this material.
Any Setting Tips for this?
Thanks for all the replys 🙂
RE: Holes in Print
I've printed quite a lot with silk filaments. All the silks I've printed with required hotter temperatures. I generally print them at 230-235 with my Nozzle X (Steel nozzle). That is equivalent to around 225 on a normal brass one.
All the same rules for tuning in a filament apply. Using a calliper measure the ACTUAL average diameter of the filament and enter that in the filament profile. Don't assume its 1.75mm.
Once that is accurized then generally you shouldn't need to touch your extrusion multiplier, just leave it at 1.0.
Silks can also be a bit softer so make sure your idler tension is suitable. Also print them slightly slower, they aren't really high speed filaments. No where near as bad as tpu but I generally set my Max Volumetric limit to around 8-10mm cubed to act as a max on whatever printing speeds I have set. Outer perimeters do well at 30-40mm/s.
and yeah aligned or rear seam generally looks better than random.
