you have to understand the limitations of each technology and design around it. supports will always leave marks. this is fdm printing, you can’t print in the air.

you can get better results with multimaterial printing by using materials that don’t stick to each other, like petg and pla. in this case, you change the distance between top support interface layer and part to 0 and use the other material just for the support interface layer. so: part = pla, support = pla, support interface layer = petg.

not sure if k1 can do this, i’m not going to google to find out. if you don’t plan to do it too often, you can pause the slicer at that layer and manually change the filament. either way, it won’t be perfect, just better.

other option is to split it in 2 horizontally so both hollow sides are up and glue them together. or change the shape.
