Adding support blockers causes raft like surface inside helmet | Frankly Built's 3D Printing & Cosplay Community | Page 1

I have a boba fett helmet I'm trying to print. Whenever I block out the supports inside the dome, it creates a solid raft-like surface inside the helmet. I've messed with cura settings but didn't see anything that jumped out. I've printed another one that was fine, so I think it's the way I'm creating the supports somehow.

Any suggestions on where else to look?

Don’t extend your support blocker to the bed.

gentle lagoon Oct 20, 2022, 1:02 AM

#

If I don’t, it adds trees everywhere

topaz kettle Oct 20, 2022, 1:02 AM

#

It shouldn’t.

gentle lagoon Oct 20, 2022, 1:02 AM

#

Yeah. Agree. Not sure why it’s doing that

topaz kettle Oct 20, 2022, 1:02 AM

#

Can you move the helmet flat to the bed?

#

What version of cura?

gentle lagoon Oct 20, 2022, 1:03 AM

#

4.13

topaz kettle Oct 20, 2022, 1:03 AM

#

They had support issues in that version if I do recall

gentle lagoon Oct 20, 2022, 1:03 AM

#

Weird. I printed another one fine

#

Let me try in 5.X

#

Yeah I’m not crazy!

#

It was random when I was using it but consistent with models

#

Had no idea

Tenor

#

I'm using 4.13.1 actually.

topaz kettle Oct 20, 2022, 1:12 AM

#

Well that doesn’t jive

gentle lagoon Oct 20, 2022, 1:13 AM

#

topaz kettle Oct 20, 2022, 1:14 AM

#

Yup

gentle lagoon Oct 20, 2022, 1:19 AM

#

#

How? This makes no sense.

topaz kettle Oct 20, 2022, 1:19 AM

#

Agreed.

#

Can you sit the helmet flat on the bed and try

gentle lagoon Oct 20, 2022, 1:26 AM

#

topaz kettle Oct 20, 2022, 1:26 AM

#

Bingo!

gentle lagoon Oct 20, 2022, 1:27 AM

#

Its still creating that raft on the inside though

#

That pic I posted earlier in #chat-printing is what it will print.

topaz kettle Oct 20, 2022, 1:28 AM

#

That’s not a raft. Those are trees with the brim on them

gentle lagoon Oct 20, 2022, 1:28 AM

#

Sorry. You're right. I see that now.

topaz kettle Oct 20, 2022, 1:28 AM

#

Can we get that pinned

gentle lagoon Oct 20, 2022, 1:29 AM

#

Have you seen anyone else run into that?

topaz kettle Oct 20, 2022, 1:29 AM

#

I haven’t

#

Assuming nothing touching the build plate causes it to span across the blocker

gentle lagoon Oct 20, 2022, 1:58 AM

#

It's cura 4.x

#

#

Same exact model and blocker in 5.2.1

#

Hey @gentle lagoon let me know if this is considered off topic but I'm doing the same print and noticed a lot of trees on the mask is this good or do I have the same error you were running into?

#

that looks good

gentle lagoon Oct 20, 2022, 1:24 PM

#

Agreed. That front visor space, the side and the back need the trees.

#

How much infill are you using? That shouldn’t take you 5 days @silver fractal

dusky glen Oct 20, 2022, 1:52 PM

#

Oh right, didnt notice the 921g filament, that seems excessive for a mando helmet

vernal drum Oct 20, 2022, 2:00 PM

#

5 days is a bit long too. With Frank's settings I got down to 1 day 19 hours.

#

gentle lagoon Oct 20, 2022, 2:01 PM

#

What nozzle are you using @silver fractal? I wouldn’t print that at .2

vernal drum Oct 20, 2022, 2:06 PM

#

Agreed I'd bump it up to .28 "Low Quality." Dunno if it's a debate or not but I also switched to standard infill @ 3% density.

gentle lagoon Oct 20, 2022, 2:13 PM

#

I would raise that infill unless it’s a prop. I used 5% on one and broke it pretty easily

silver fractal Oct 20, 2022, 2:56 PM

#

Thanks for all your help with this! So I took a look and I have a 20% infill and I'm using the standard cr-10 v3 nozzle which I believe is a .4 @gentle lagoon @vernal drum

I do plan to sand/paint/finish this helmet and wear it so I'd like it to be fairly strong - do I not need it to the at settings that high?

gentle lagoon Oct 20, 2022, 2:56 PM

#

Nope. I’m talking about your layer height, not your nozzle

#

This is a settling in cura

#

I would lower than infill to like 7-10%.

silver fractal Oct 20, 2022, 2:57 PM

#

Gotcha, yeah the layer height is at the preset .2

#

So I can drop it to low quality without much concern for the structural integrity?

gentle lagoon Oct 20, 2022, 2:58 PM

#

In general if you’re going to sand, raise the layer height to the highest your nozzle allows that let’s you finish your print

#

Yep

topaz kettle Oct 20, 2022, 2:58 PM

#

you are talking about .08 of a mm

silver fractal Oct 20, 2022, 2:59 PM

#

Hmm, sounds a lot smaller than it feels changing the setting - appreciate the context @topaz kettle

I'll make the changes and slice it to see what the new results are.

topaz kettle Oct 20, 2022, 3:00 PM

#

yup.. I print all my stuff at .28 ... If you are sanding it anyhow you are sanding away that much... If you are doing minis or something smaller you might want to reconsider
