Topic: infill... support.. overhang.... i have no idea the problem!!

so i have no idea why i am getting the result in Pictures 1 & 2....

What i am looking for is a hollow "bowl" like piece.... or a funky hat if you turn it 180 degrees
Anyway.. i keep getting this "infill" or "support" which is creating a core that is allowing for punching out the top of the piece. as you can see in the pictures. The end result i would like is a nice print with no core and support...length of time to print this is of no concern.. so any advice would be great.. i have included the STL file for your review...i would like my print to look like the STL as much as possible...must be able to hold water if used as a "bowl" (i think this is called Manifold)(see im learning something from reading these forums!!) Can you help? i sure hope so..

PS: these renders were done using 1.75mm PLA at .3mm resolution and using the Stock Solidoodle 2 Pro.
Software: Slicer downloaded from this website as of 1 week ago.

PPS: I'm a noob.. so please speak to me as if i have no clue what i am doing Thank you!!

Re: infill... support.. overhang.... i have no idea the problem!!

My first suggestion is to print that with more than one perimeter. Start with 3 and see how you go.

Leave the support on, I think you need it regardless. You could try printing it upside down (with the support underneath between the bed and the cap).

For sealing, consider checking the 'spiral vase' setting in slic3r, this can help a little.

In other news, there are a few bubbles showing in your part - you may need to dry your filament. Store the reel in a sealed container with a whole lot of damp-absorbant ("damp-rid" is a common brand here, they're all called something similar, find it in the laundry section of the supermarket or from a hardware store), and let it dry out (without opening the box!) for several days.

You can also dry it by putting the reel of filament in an oven, but be extra cautious about this as it's easy to ruin a whole reel by melting it or the spool (google this a bit, understand what you're up to, 80-100 degrees CELCIUS max, check it regularly).

Re: infill... support.. overhang.... i have no idea the problem!!

Thank you for your reply. I am not sure what version of Slic3r i am using. It is whichever version came with package that i was told to download by the Solidoodle site. I have yet to find this setting that has a checkbox for the spiral vase (whatever this is...)

Welcome to Arkansas in Spring. The humidity here is crazy all the time! I do not believe i will be sticking any of my filament in the oven. Thank you for the suggestion though!

On another note i am going to try to print this upside-down. Also, the setting were set for 8 perimeters vertical. Is this setting for wall thickness? If so, would i be better off leaving it at 8 or setting it to 3??

PS: Also i am still looking for a suggestion that would allow me to print this without support material. Thank you in advance

EDIT: Part 1:So upon closer inspection those are not air bubbles... when looking after the slice you can in the mesh these little seperations....

EDIT Part 2:Ok, so i went to the Slic3r website and got the new Slic3r loaded into Repetier-Host. I found the Spiral Vase setting and checkmarked it...about to do a new print...In the Sliced window i see my object looks like it has been infilled... How can i stop this since i do not want it Infilled??? thank you

Re: infill... support.. overhang.... i have no idea the problem!!

If you are willing to live with a slightly different shape, if the inside surface comes to a sharp point with a 45 degree slope, then it could be printed with no support. You could even keep the outside the same shape and fill in the insides so that the "cup" has a conical bottom. I would do it in openscad, but not sure what tool I would recommend for a noob.

Re: infill... support.. overhang.... i have no idea the problem!!

Spiral vase will override your settings and print with 1 perimeter max.

I printed your .stl but it i sure cant hold water (see pics)

I only printed with 2 perimeters and I'm not sure if more will help. I used my standard 2mm profile but “Solid layers: Bottom” set to 0 and Infill also to 0. (and no support)

Re: infill... support.. overhang.... i have no idea the problem!!

Oh thank you for doing the test print on that!!! im glad to see that it is not just me LOL!!! However, now i am at a loss as to what is creating that issue with the top portion of it. I mean in the mesh it looks perfect!! There are no Holes in the mesh.. *shrug*

CarstenBe: I have duplicated what you have done and i had solid layers bottom set to 3 and infill set to 0. with support even!!! and i get what you see in my earlier pictures!!!

PS: Perhaps an awesome community member could look-over my .STL file and tell me what is wrong, or even fix the dang thing for me. As always... Thank you all for your responses and your help!!!

Re: infill... support.. overhang.... i have no idea the problem!!

I would try increasing the perimeters to 4 or 5.

Increase your extrusion multiplier by .05

slow your speed by 20%

no support

a fan blowing accross the top of the part will help as well.

Will that help with dome?

In theory, yes... But I tend do do most of my work in ABS and Nylon.

There are many factors that come into play when printing any overhanging feature. Practice makes perfect.

Re: infill... support.. overhang.... i have no idea the problem!!

I got a couple messages from people wanting to know if I got this printed how I want....unfortunately I had an extruder clog so I have yet to attempt a new print with the suggestions here in the post!! However
, after such a big headache with unclogging this beast I have got to the point where I am about to assemble the extruder back together!!! I will keep you posted on my success or failure!!! Thank you all again for your help!!

Re: infill... support.. overhang.... i have no idea the problem!!

...back to square one.

Does this have to be in PLA?

Can you post you slic3r settings? In particular I want to see your layers and perimeters settings and your speed settings. If you could also post your filament settings that would help.

Maybe could try a different slicer. I have sliced this in KISSlicer at .25mm layer height with 3 perimeters and can not find a reason why this would not print.

Re: infill... support.. overhang.... i have no idea the problem!!

An extrusion multiplier of 0.6 seems a bit low...Have you tried printing a calibration cube with a single extrusion width wall thickness (0.42mm)? If not, print one and then adjust your extrusion multiplier accordingly...

Re: infill... support.. overhang.... i have no idea the problem!!

I tried to slice the .stl this evening...RH indicated the part is not manifold. Tried to repair with Netfabb to no avail. So just for kicks I imported the .stl into Solidworks and remodeled it. No manifold errors and printing now; we'll see how it goes...

Re: infill... support.. overhang.... i have no idea the problem!!

Oh well...used .3 layer height; no cooling...guess I should have cooled it a bit! Otherwise it sliced fairly well. What is the reason you desire no infill vs solid infill?

Re: infill... support.. overhang.... i have no idea the problem!!

yes, no support the inside. i dont mind if the last 10 layers are solid towards the top if this would help the peak of it to print better.

im actually thinking about abandoning this print and trying to turn that bath bowl into a mold so i can make a clay bird bath... but i suck at 3d modeling... it was hard enough to make that thing!! i would not even begin to know how to turn this into a functioning mold lol

I think that changing the infill to 1 might help those top layers stick together; descending diameter circular layers can cause stress and separation...

Another idea for a BirdBath...(It may look more like an ashtray, I never said I was an artist LOL.

Hang in there with the CAD...It may seem daunting when you're starting out, but soon you'll be able to pre-think your designs and the steps to take in order to create them. I only really started about 2 years ago; I'm certainly no guru, but the STL I posted took only about 5 min...
