try to increase the support,the model is big anh heavey

The supportes held just fine, to the build plate and to the model. Its the model that failed.

Also the base is hollow on the back and is only 1.6mm thick all the way along

The supports might've held but the model is terribly balanced. If gravity makes it flex some parts of the model won't get close enough to the fep and layers won't stick anymore. Try making a wider base and supports that support from side to side as well.

The thing you have missing there is a platform, yes you will use a little more resin but the small surface area of the supports is not really enough for the size of the model its trying to hold. The platform will have a larger surface area to vacuum to on the build platform, the supports become a part of the platform and will have more strength. If you Imagine a head of hair, the skull being the fep, the skin being build platform and if your lucky to have enough hair being the supports. If you dont want to build a platform, rather than print the model at 90deg. Lean the model towards the underside and rerun support, I think you could probably get away with a 15deg lean. You will get more supports. And last option is slice the platform and weld it together with resin and a UV pen light of some sort. Making 4 pieces will probably be less printing time than trying to build in one go.

The supports and platform are rock solid. There is zero signs of any wobble up until this point. Something happened at this layer that caused the rest to not adhere to it.

The base on the plate has a larger surface area than any of the subsequent layers.

Delaminaton is usually a sign of low exposure. But not sure that's what it is.

If you haven't messed with it since, check to see if your build plate is still level. Take the vat out and put a piece of paper down there. Move it till it engages the paper, and check all 4 corners.

Since it happened during a large cross section, the plate may have moved from suction forces. Usually you get a big layer line, but being that thin, it may have killed the whole print.

I'd suggest taking the build plate apart and cleaning the ball joint. Only takes a few minutes, including releveling the build plate after.

Yeah, the more I look, the more I think your plate shifted. The parts that kept trying all seem to be growing forward, instead of just up.

Bisected model. Print 2 halves. Or you can keep trying to print the entire disc dangling like you think you supported it well enough, to which youd say you cant tilt it more.

Chris Carter over hang. You made over hang.

Fred Bey wrong. Look again. Rock isnt thicker.

Can't print in 2 halves, the model needs to be printed in one piece

Chris i have to disagree, nothing has to be printed in one piece, everything can be sliced and then welded together.

Nikola Pijanac and I have to disagree with you. Some things, especially very detailed surfaces need to be printed in one piece. As welding them together will not keep the detail properly

Gonna post a link to an old post with some discussions around similar problems, might have something useful.

And another cut and paste from a previous discussion:

Some of the possible causes:
* Bad USB stick or USB cable (or corrupt file)
* Bad PSU
* Excessive exposure time for base layers
* Non-smooth FEP (needs better cleaning or replacing)
* Worn / overheating stepper motor
* VREF for stepper motor low.

And one thing to try: does the problem disappear if you do a dry run with no vat or resin in place?

Niall Forrester ill try that! Thanks for the link too!

lvoe it

WOW!

Check your print dimensions in your slicer.

did U use supports?

I’ve had that happen to some of my dice prints too, but then the same file comes out fine on a second print. Haven’t figured it out. Good luck!

That's one of them there loaded dice.

It was a natural 1.

^ this.

Roll with it!!

Check out the Gaslands page too. Good luck!

check out Cold Casting using epoxy resin and metal, copper, brass powders etc.

Woww

aw man, I've been looking for an stl set of all the main characters.. your's are great

Amazing work. Any chance you are sharing the file?

Gorgonites for the win.

Michael D Showalter much appreciated, I hope to offer them for sale once all 13 characters are finalized.

Tony Shadman thanks, I do plan on offering them for sale in the future

Clark Paints here’s to hoping ?

Still love this film as much today as when I first saw it

Richard Thomas I’m right there with ya ?

J.R. DeJesus in the near future I hope. ?

This guy looks like Ookla the Mok

This is a known issue when you hollow in chitubox.

FIX: Use anything else to hollow such as workshop or meshmixer.

Put your stl trough windows 3d builder. It will clean it for you. And yes hollow it with meshmixer!

How does one put it through windows 3d builder? just downloaded it

Its not an issue with Chitubox. Its an issue with poorly created STL files. Put the file you have through something like Netfabb repair the stl and then slice you will see a big difference.

A lot of artists out there create models without consideration of the birds nest mesh that they create as well. The slicer trys to slice everything it sees. You Can't hollow a model properly if you have vertices pointing in a million directions.

Looks like supports, and bases for supports.

Eli Allan my windows 10 got builder standard

Just search 3d builder in the search bar from windows

Yeah, that's clearly Layer Zero in both pictures. The scrambled one is support bases, not a bad model.

Thay seems like a long time for post cure. I do like 5 mins with clear...

Overcuring causes brittleness, you shouldnt need more than like 5 minutes or until a nail no longer dents it

Or as I like to call small printing errors, "battle damage!" Lol

Even if it fails 50 times before you get a good one it will still be cheaper than an official WotC spectator. Because of the lost mines module the damn thing are like $60. And that's if you can even find one. Took me forever to get ahold of mine(before I got into 3d printing).
