Does this "math art" vase require support and/or a bed?

Recommended Posts

There are areas under the midsection that would be hanging without some sort of support during printing. You could try it without it though, but I would think you need support.

Once again your eagle eyes were spot on kman! Asher aka Dizingof confirmed that this model needs support under the flat surfaces. I'll add that via Meshmixer.

With that amount of fine details and holes, I would print it slow and as cool as possible. This will also reduce curling up of edges. Maybe 190°C at 25mm/s, if your PLA can handle that? Maybe you could cut out a small part and try that first, and then manually adjust temp, to find the best settings? Also, be sure to have a big thick stable base, otherwise it will be knocked over.

I've taken your comments on board - thank you Geert.

I'm not sure what you mean about a big, thick stable base since this model doesn't have a base in the usual sense.

@nzo do you know @labern?  He is also in Auckland, NZ.  He is a friend of mine.

 

If you print it I think it will print.  The biggest danger is how it attaches to the glass bed - that could come off - I'd be tempted to cut off .5mm of the bottom (set Z to -0.5mm in cura move mode) and add a brim.  But I think this model will print okay without any support.  It will be ugly under that "base" but it shouldn't completely fail.

 

If you have a UM3 though then much better to print this with dissolvable support up to the base.

We said hello to each other shortly after I joined the UM forum but nothing more than that.

 

Thanks for the tips. I've been in contact with Dizingof about the "Ennepper Vase" in my OP - about his support strategy for a piece like that vase.

He sells finished prints of his beautiful commercial Maths models so I can understand why he might be reluctant to share any making details. I also appreciate his generosity in providing so many free models to download but he includes no making details that would be helpful to a newbie. That's too bad but I think I understand where he's coming from.
