They make a resin slicer?

They use 1 slicer for their FDM and resin machine.

Well all I can tell you is not to auto support! And then you may be able to change the contact size and depth.

Whack the density up to 200%

I understand what are you saying. But I want know why some people can print perfectly with only PrusaSlicer's auto orientation and auto support lol

still the same ?

Chitubox auto support gave me this

Sometimes I add the following steps...
Export from Prusa with supports
Import into Chitubox
Go into the supports tab
Set to raise the model 0mm
Set the density low
Generate extra supports in Chitubox

Basically, double up, but keep Prusa's orientation and stuff, because that seems pretty reliable

Reggie Grahita Adhyatmaka Djatnika Thanks

What do you do about the raft?

this would fail. the lowest supports are to small. in the support section top right corner Z-height lift or something like that default is 5 set it to 7 or 8 then redo the supports.

same with the prusa slicer you need to raise the model of the bed more so it can form the minimum support length.

Reggie Grahita Adhyatmaka Djatnika I usually leave it. I like the little angled lip it gives... makes it easier to remove the print

Just finished printing. Just as you said, the bottom section was failed

How do I raise the model in prusa? Everytime I tried to move it to z axis, it return the the plate

EDIT: Never mind, found it

what was it. as i cant remember and i am sure me and others would like to know :)

Cannot fully see the part but something like that would surely print straight off build plate

In print settings, you go to support section and turn off the "pad around object" to be able to edit the object elevation below it.

The part is like this

google "do it again"

you can just make a mouse macro

Not really what I was after as I was hoping to just be able set it going on around 100 models and then just leave it, can’t do that with a mouse macro

sure you can

do the support part, save it using a spreadsheet or notepad w/ keyboard commands (click on window border, then arrow key down to select a cell, then copy, paste into save window file name)

click on the window containing the files, click down arrow, drag into chitu, repeat

it will take a few tries to get the script repeating perfectly but its entirely doable, ive done it with thousands of repetitions in CAD programs

Derek Reihe I’ll give it a try but it seems massively more awkward than just a simple cmd line option like the supports and the exporting!

you can try emailing them but I dont think what you are asking for exists

Derek Reihe yeah, it’s what I feared, but that’s for the help!

I would try laying it flat and let chitubox do the supports. See where it exceeds the boundaries and cut there, you'll stand a better chance of no warping. Your print time will be quicker. Choose the side for supports that will be least visible.

That overhang will print, a helpful tip is that a standing X shape will almost always print, so a perfect 45 degrees is pretty safe as long as you have good build plate adhesion.

You are flirting with failed prints. And that is the biggest waste of resin.

You can set the thickness of the supports, along with all their other settings, by going on the right side of the program, it will show "Pad,Supports" under the stl, and you can right click on that and choose the settings you want to modify. That said, the thinner your supports, the more likely they will let go due to suction from the prints for a failure.

Failures create more waste than successes do because you have to use twice as much resin.

Making supports thinner increases the liklihood of failed prints.

Just make sure you add enough support so you only have to print something once.

Unless of course it is something you are making multiples of I guess.

Get rid of the raft and keep your support bases to 1.5mm thickness

Is it hollow? Could some resin be trapped inside?

I don't think the volume calculations take into account any support material? are you weighing it after support material removal?

the supports are very minimal, and Im weighing the raft and adding a little extra for the rest of the supports. And I calculated it with support material in both chitu and prusa...

No, very thin parts, only about 3-4mm thick

Probably inside the print. Like parts between hollowed areas. Sometimes when you Hollow the print, it seals off another part of the print that is also Hollow, but fills with resin because there are no holes for resin to escape from these sections. Check for that. It happens a lot on prints I've hollowed.

Nothing is hollow, the parts themselves are quite small, only 3-4mm thick.

How about the resin that sticks to the model and gets washed off afterwards? It is known the software estimates are showing less then used in real

You’re using resin on places the software doesn’t take in account

Resin is stuck to the print, that is washed off, that can be quite substantial... so there is "loss" there.
Then there is resin that "sticks" to the buildplate, when your print is done, you will most certainly see some resin dripping off... leave it fo r long enough to regain most of it.
And then there is the resin that goes "on top of" the buildplate, since the build plate goes into the resin, there will always be some resin left on the non-print side....

Resin sticks to the model and the plate as it prints. That's what you have to clean off before final cure. Not a huge mystery.

Ahh, i think i have tricked myself by trying to be clever. I usually leave the prints waiting for an hour or so before cleaning to let the resin drip off. That would explain why there's resin left over but the print failed.

Thanks

I do that myself. I think the longest I've let them 'drip dry' was 2 weeks. lol

Hope you get things squared away!

add more resin mid print, just be careful not to create bubbles. and careful not to shake the printer during opening, is difficult to gently open the door sometimes

Thanks for making the Validator even better...

Thank you for your great efforts Sol!

You are the most amazing person alive! At least until I find something else shiny. But seriously, this is awesome, thank you.

If you're updating the Validator, are you taking requests?

Because the ability to flick up and down between layers while in the zoom-in mode would be hella handy.

Christopher Fugate add your request to the GitHub, there are a small group of people who are currently improving the application.

Thank you! Good work

Great

Many thanks to all for the positive feedback. I've been busy printing for a couple of days now and so far every print has been successful.

As soon as I have implemented the gamma correction and cleaned up the code, I will make a pull request so that the changes are included in the main branch.

Sol Aris Any idea what would cause this, or more importantly how to fix this?

Robert Jeppesen You need a newer Java version. The program runs from version 11, the error message says that you have Java 8 installed.

Ok, thanks

Are you importing it or opening it?

Dan Elent tried both

"export plate as an stl including supports" option, this will save it as an .stl instead of a masked .sl1 file.

Where exactly do they tell you its invalid?

Jacob Hale I did that.

Very strange

For example, i'm trying to mirror the right arm of a model to make a left arm.
But the left arm I mirror won't print, and comes out as a shaded object in Chitubox

It sounds like it's treating the object as a separate model. Maybe try joining them in Meshmixer or something?

Something like this

Import into blender, go into edit mode, normals, recalculate outside. If you really cant do it, contact me here I can do it for you...

Darko Miljak thanks man. I'll give it a shot.

select all with A and then recalculate, export as stl

You need to export the file with supports and it will create a new stl file. Open that in slicer of choice.

i can only export as a *.sl1 file, which chitubox can't open.

Export as stl with supports

Charles Lease under file there is a export with supports choice

export with supports is grayed out. and no supports show on the model. but pad/supports show on the right...

I believe once you have supports showing the choice will be available.

When in Prusaslicer, select what you want to Support, then on the left at the bottom you can select supports.
You can auto support or add manually. remember to select apply if you do manually.

Then the supports should be visible, you can choose file -> export -> export plate with support.

Charles Lease there are no supports added yet.

that's what i was missing, it was processing and i dind't realize it. thanks!

the supports are not yet on your model

this communit is the best! it was slicing to create supports and i was impatient/didn't see the processing bar. took it only like 5s...guess too much coffee this morning...

Xi-Sheng Luo lol thanks, i was sending the pic for the poster.
