Remove support before post-curing, but I’d sand after post-curing. Altough, I don’t need to sand.

Following

Some people do, some don't. I like to on model that are tough. If the model has small parts that might bend before curing I'll cure it first.

I see a mixture of things, some say to cure with supports some say not. I usually wash with supports, then cure without supports but may try with supports as one delicate model fell apart when trying to remove them.

Always removing before curing. The group suggested putting it in hot water before pulling off the supports and holy shit.. it works so well. I do t have scarring on the prints, they don't break the prints. It's amazing.

Yeah, warm water for a few seconds and it practically peels off. It's satisfying like picking a scab

Definitely the best bet on delicate and non-delicate prints is clean then warm to hotish water and supports almost fall off on their own. THEN cure. Sand as needed. Cutting those supports off after curing causes micro spears bouncing around the room.

Also check your contact depth into the model. Me, I only go .12 into the model.

Gary Slovinsky ok. That being said I just finished my first print and the detail is amazing, however with the supports off there is still some post.
What do you use for supports setting on yours? On my Tevo I would have good prints, but my supports would make it look like shit until I found out the right settings and now my prints are almost flawless. Looking to do the same with my resin prints. ?

Robert Clauff i use a contact depth of .12 and mostly med and small supports. BUT I don’t print minis or (at this point) extremely high detail. The most detailed item I’ve made was an agents of shield/hydra combined coin, a couple mm bigger than a quar ter. Printed vertical.
But I still stand by ipa/mean green wash then warm to hot water for initial support removal then cure. But as you mentioned having the right settings is key. My settings wouldn’t help you, i print more simplistic designs which require less finessing than most other prints.

Robert Clauff (addendum) I’m confused here. On your post to me was most of it related to FDM prints? I’m only asking since your last sentence says you were looking to do the same with resin prints?

As a side note: I finished printing off the easy be d leveling adapter (photon) and i neglected to remove the supports first in hot water, I then cured it. And after removing thr supports was a nightmare and the thumb screws look like crap.

Gary Slovinsky yes i was talking about my Tevo Tornado. I want to get my resin prints to the point where I hardly have to touch it after I cure it.

Wet sand with high grit for the last pass

First, the model needs to be high quality. Without that, settings won't matter.

For print settings, we need to know what resin you are using.

It is high quality.

I'm using the basic Anycubic White. It says UV Wavelength 405nm

Bump

Bruno Shepard start here and tweak as you learn. This says Anycubic White should be around 15 seconds exposure time per layer at 0,05mm layer height.

Sean O'Hayer thanks mate!

Noone can tell you the best settings, because they depend on so many factors. Do an RERF test and you'll get to what works best for your current conditions.

Lol, I thought it was cheese

I had something similar and what I discovered was that a job would complete but then the next would fail because of resin left on the fep from the successful one. Not 100% cured but enough to make it fail.

Turned out the LCD was failing and was Curing a 'shadow' on the fep between layers when it should have been dark.

Changed the screen and it was fixed, improvement in print quality too!

That might be it. I've also emptied the vat and the fep looked fine. This is the exposure test

I think my screen failed. I turned it off and back on again and then it was acting normal...? That's so weird

Benjamin Matthew Harding mine looked fine on the exposure test but it was clesrly letting UV through when it shouldn't have.

Hmmm.. what's weird for me is it wasn't doing any uv light and then after turning it off and back on, it showed up again. If this doesn't print then I'll have to get a new screen for sure

If your screen is old (mine was 14 months old with no dead areas) you may be best doing it anyway, the improvement in print quality very noticeable!

It's only 3.5 months old, as I got it for a Christmas gift for myself.

Hmmmm, there is no saying how long each one lasts. I've heard of people having them degrade in that time though. I was just lucky.

Dang. Well thanks for your advice. We'll see what happens

Benjamin Matthew Harding Good luck,

nope only equivalent as the Sun UV rays if that

No, wrong wavelength.

Not quite the right wavelength.

I have one of those dish heaters in my garage. That could work really well at flash frying those buggers.

No, you need lower wavelengths

You can get either sterilization led strips or HG bulbs (which are pretty cheap actually)

And you run a risk of...

And a lot more care, as exposure to those is very dangerous

Cristian Cozma yeah definitely, you need to get out of the room, first time you'll get a tan, the next time - something much less pleasant

Check the connection first, but it may be time to replace the screen entirely.

Same as above. I had this issue and photon sent me a new screen since mine was only a month old when this happened

Yamamoto Tifa Thank you, and dont you know how much is guarantee given. I mean is it still possible to replace it for free. I bought it last summer

Good luck! Contact either Photon directly or the person or company that you bought it through. I bought mine through Amazon and they helped me connect with photon. I meant it was a little difficult to reach out to them myself because there is a languag e barrier. The emails were all in English but I'm not sure if all of my intent made it through because some of their responses were off topic or seem to ignore something I already said. Eventually I was able to get a free screen from them

Jim Nelson Thank you, and dont you know how much is guarantee given. I mean is it still possible to replace it for free. I bought it last summer

Abror Orifkhonov I just checked and the screen is warrantied for 3 months. It's considered a consumable, because they do wear out over time.

Mine does that from time to time. Usually I turn mine on without the usb plugged in. Test the screen then plug the USB in and continues to work fine - I'm guessing mine is going to need a replacement soon too though. That trick likely won't work for too much longer

oh no....

THIS is accualy realy helpfull post... i have my UV flashlight next to printer and its in dim place... now im gona make absolutly sure noone in my house do this unthinkable mistake

Hahhahaaha thank god I dont own a uv flash light lol

The clear-ness you are seeing is the uncured resin filling in the tiny layer lines that refract light. You can get some of that back by clear coating your clear prints. It would even better if they're flat and you can sand then clear coat

Yeah...unfortunately my first thought is the motherboard

Scott Pavlich I have a spare one , so I’ll try that.
