Layers split apart (delamination)
9 usi3d guides for “Layers split apart (delamination)”, each with the likely causes, how to check which one is yours and the step-by-step fix, with each manufacturer's official sources.
They all apply to any FDM printer, from any brand.
Each guide summarises the official documentation and says whether usi3d has already verified it on a machine.

When printing ASA or ABS the room smells strongly of plastic, you feel discomfort or you are worried about breathing the fumes; or, when you ventilate to get rid of the…
- High-speed PLA: which temperature and flow to use so it does not come out with gaps or weak layers
With a high-speed PLA (those sold for printing at several hundred mm/s), the part comes out with gaps, walls thinner than intended or layers that split easily, the shine…
- Layers separate or the part cracks between layers
The part opens up in horizontal cracks or splits cleanly along a layer, often with the edges bowed upwards.
- PETG: layers that separate or brittle parts that break along the layers
PETG parts split between layers when bent or when a screw is tightened, break cleanly along a layer with little force or show horizontal cracks; sometimes the surface is…
- Wet filament: how to spot it and dry it
The filament has picked up moisture from the air: bubbles or a little smoke appear when extruding, the surface comes out rough or lumpy, there is a lot of stringing and…

When printing nylon, bubbles and popping come out of the nozzle, the surface is uneven and stringy, parts are weaker than expected, or they warp and come off the plate.
- Silk PLA and PLA+: which temperature to use and why they lose shine, have weak layers or clog
Silk PLA comes out matte or with uneven shine, its layers split easily or it clogs at high speeds; or you do not know which temperature to use for a PLA+ because it does…
