Currently I’m working on a print that has imbedded magnets. Sometimes the layers right above the magnets are not adhering correctly. I have added ironing to the top most layer and that seems to have helped but I was wondering if anyone had some other recommendations to try.

I’m using a P2S

my settings are pretty much unchanged from the initial. Just some changes to infill density, infill pattern, added supports, added brim, and topmost layer ironing.

I’m using PETG Basic

Here is some pictures of what is happening

The magnets are snug and there is not an excessive area above the magnet and the next layer. It just seems to not adhere and then creates spaghetti for the first layer then the second layer and the ironing seems to be fine

Do you have a little space above the magnet before the layer that covers it?

The metal may be causing the filament to cool a bit too fast if the plastic is being dispensed right against the magnet. May or may not be your issue but I try to give a space above metal I embed (nuts mostly) where it’s more unsupported span than printing directly on the metal.

There’s a small gap above it maybe 1-2 layers. The heat distribution would make sense. How big of a gap do you use?

1-2 layers worth is all I use. Don’t know it it’s the real issue now though since it sounds like you’re using similar.

Was thinking about it and maybe going a little more clearance might still help?

This is a frequent issue people overlook. Whenever I’m embedding hardware into a print, I’ll set it on the print bed to preheat while the print is going, then there’s less of a delta when it’s time to insert the part. Can help avoid unexpected part shrinkage in high temp prints, too.

That would work really well i appreciate the recommendation I will try it out.
