Vase mode without seam

Recommended Posts

Posted · Vase mode without seam

Hi!

I'm trying to print this model of a horn, which will be printed in a glass like transparent filament, in vase mode (aka spiralize outer contour). Because of the transparency, a seam is REALLY visible, so i would love to print the model without it. Putting the surface Mode to "Surface" does remove the seam, but also removes the bottom of the model, which is a deal breaker for me. Any way i could keep the bottom, and have no seam? Like can't i print a platform of one layer, and the print the model on that?

Thanks in advance!

Hey there,

 

Have you experimented with the 'Z seam' feature in custom mode? This allows you to manipulate where the Z seam is placed.

Randomizing the Z seam may be a solution in this case - this will place the seam in a random position for each layer.

That's not a bad idea!

Got a 3mf file you're willing to share? or a thingiverse/youmagine/other-online-repository link?

Just had a quick try myself. By turning off 'Spiralize outer contour' and randomizing the seam I got (imo) a slightly better result. 3mf will hit your inbox shortly.

 

The geometry here is a difficult one to make a z seam disappear from completely as each layer is a circle, so there's no corners to hide the seams in.

 

The alternative is to post-process the model, e.g by creating a seam at a constant point so that it can be removed with a knife/sanded/etc. But given you are using translucent material I'm not sure how feasible that is.

That's actually a pretty good idea to slice it with 0% infill, but i don't know if that's gonna be an improvement with all that solid infill along the wall. Probably gonna be pretty visible once printed. Ideally what i need is just one line all the way up.

 

I was thinking of using the Surface Mode: Surface to to get it seamless, this removes the bottom. But what i could do is first print the bottom 0.4 mm high, add a 0,4mm or so z offset in the rest of the model, and print it like that.

Theoretically giving best of both worlds, isn't that what Surface Mode: Both is supposed to do?

One obvious question is: why is there a visible seam in "spiralize" mode at all?

Shouldn't it be a continuous extrusion?

As i understand it, all vase mode print have seams, its's just that slicers are usually really good at hiding them. This model being particularly hard with circular layers, with no corners to hide a seam. I guess Surface Mode: Surface could be interpreterad as a raw no compromise vase mode, however this removes the bottom layers, which i need.

But i should say i'm no expert in this area.
