beautiful

From where this model is? Looks like a tiny castle I have seen from a painter a while ago

I have to ask as everyone one seems to, where did you get this from or did you make it yourself? It look fab and I would like to print one for my wife.

Riika Magnus thanks

That print came out very nice!

Clear under UV light.

Normal Grey Color

I printed one on the Photon Zero and it mostly came out ok. Some of the tower tops stuck to the FEP, and there was some separation near the middle

What resin were you using?

Looks awesome!!!

Riika Magnus AnyCubic black

Jonathan Basseri eek that didn’t turn out so well. Did you use the settings for that color that are in the spreadsheet?

Rubber / plastic scraper. Lot faster too ...

There's a bunch on thingiverse,but all have too big parts to print on photon. Find a friend with extrusion printer

I have an FDM printer :D All the ones on Thingiverse are for other Photon models that have bigger vats.

Riika Magnus sorry,thought the zero was same as photon

James Turner Nope its a bit smaller, about 15% so I am going to shrink one of the stands I found on Thingiverse by 15% and see how it goes!

Sadly you did nothing wrong, this is what it always does when exposed to UV, ironically. Apparently you can get UV-blocking primer or lacquer coating which will prevent it but not found any yet.

Simon Wilson huh. So why do they make clear if it doesn’t stay clear (since I’m assuming leaving it in the sun would do the same thing?)

Nothing, it's just cheap resin, cheap clears and whites will yellow

Do you have a suggestion for a clear that wont yellow, by any chance?

Riika Magnus monocure

30 seconds to cure

Good question! I tested my prints by putting them on the window sill and they gradually yellow over the course of a few days, not really used it since as I needed it to be crystal clear like when it's just freshly printed! Maybe there's a better one out there that probably costs more?

It will lighten back up likeiy

I have heard (from somewhere) that if you immerse it in water while curing, that it will prevent the print from yellowing. ?‍♂️ worth a try maybe

Stefan Giudici Thanks, I'll check it out!

John Chrapkowski 30 second?! Oh, I really over did it, LOL.

Kyle McPherson Interesting!! Maybe the water refracts the UV rays so they aren't so harsh?

Riika Magnus from what I remember the yellowing is due to air exposure.

So there is a technical reason why finding clear polymers that don’t yellow with UV exposure is really difficult, from my meetings with epoxy resin manufactures, the polymer in question needs to be completely stable and non-volatile, which is incredibl y expensive to manufacture. It is theoretically possible to create a clear photocurative resin for 3d printing with the same principle but you would be paying $$$ per liter

Riika Magnus You need to estimate how much "resin needs to be cured"
The "wireframe" is very thin so does not need a lot of extra time curing.

If you'd print a solid block of that size, you might need more than 30 seconds....

Xi-Sheng Luo Good to know, thank you!

Miles Redman Thank you for sharing! Very interesting!

Riika did nothing wrong people! Nothing wrong! It’s not her fault the resin producing cabal LIES!

I’ve heard heating it significantly will remove some yellowing, but haven’t tested myself yet.

You did nothing wrong, sadly that's what happens when you cure your "clear resin" prints

Humm... Like, say, with a heat gun?

Just a little cross-linking of the resin.

All clears will yellow under UV, some more than others- but I’d say that it’s overcured. Thin parts need much less time. 60 sec might even be too long.

I’ve had pretty good luck so far with the Clear Blu from Siraya Tech.

Riika Magnus , something like that. Once again, this is only what I’ve seen in other groups. Might want to look into it a bit more before attempting.

Nice.. ? ? ? Mr cleaning is based on? Better ore equal to ipa? Thanks ?

Ivan Del Bene I’ve never used IPA, I just watched a video from Uncle Jesse comparing Simple Green, Mr. Clean, Mean Green and IPA. He liked Mean Green the best but I wasn’t able to get any so I went with Mr. Clean.

Hello Riika! Check out my Newbie resin printing Guide. It should be usefull for you!
https://www.facebook.com/groups/AnycubicPhoton/permalink/1959611750850124/

In this particular issue - Clear resins tuen yellow when cured longer than 60 sec (resin dependent) So use little time for cure.

Tom Sargison thanks, I will check that out!!

Riika Magnus wich is the main ingredient of it? Ammoniac or alchol based? ?

A lot of people are having to use alternatives to IPA. Riika Magnus another option that doesn't seem to be leaving the shelves is denatured alcohol. Like this stuff https://www.homedepot.com/....../Klean-Strip....../100139444 . I just bought some Simple Green to try out, because there is 0 IPA anywhere as would be expected.

Ivan Del Bene Mr. Clean is ammoniac based. Are you posing that question because ammoniac should be avoided?

Chris Armstrong nono I was thinking about it because I replace tamya solvent for my airbrush with a glass ammoniac product.. And worth it ? ?

Riika Magnus in conjunction to what he said about the resin cure time, if it sits stationary in the uv light, you’ll have those spots that are more heavily exposed. It’s good to rotate the print in the light, or have total exposure from all sides to evenly cure.

Corey Ardwin That I do know. I am just temporary using my UV nail dryer (I actually do use that for my nails, LOL) until I build a curing box (it will have reflective sides, UV strip lights and a solar turner). In this scenario I cured for 60s, then rotated the object, and did that three more times as I was unaware that 60s probably would have been sufficient, LOL.

Yayyy!!

Jolene Sweeney I gave up And just stuck it in there. Now I’m curing it in my nail light.

LINK OF ULTRASONIC PLEASE

Riika Magnus nice! Yep I bought a uv light and a whit box with a spin table. :) I use acetone tho! Mean green did not work

Jolene Sweeney I used Mr. Clean today. I think it cleaned it alright ?‍♀️

How long are you supposed to cure it in the UV light for?

Riika Magnus I left mine for a out an hour honestly. I did 6 hours too wasn't an issue. But I looks like about 20 min is fine roo

Yea I had a terrible time! Lol but working well now.

Jhon Pier Acuña Escalante I got mine on eBay, it’s the 2L model for $59

https://www.ebay.com/....../1-3L-2L....../312719889097......

Jolene Sweeney sooo I did a about 4 mins in my light and now it looks kind of... burned?

Riika Magnus that's odd.... mine is not in a nail lamp and the model is 6-8inches from the model.

Could be because of the clear colors? I've only printed in gray but trying clear tomorrow

I never heat, if I go from the printer directly to the ultrasonic (3-5mins max) the supports come right off

Jolene Sweeney mine was right there.

Rigo Arevalo I was just doing the test print so no supports to deal with. But thanks for the info!!

Mmmm can't help much on that! My light is purple ?

Jolene Sweeney mine is a purple 405nm light, I think my camera just messed with the exposure.

Riika Magnus oh ok! I bought this one from Amazon


3D Printer UV Resin Curing Light... https://www.amazon.com/dp/B0834N3Z2L......

I have that and really like it

Rigo Arevalo Jolene Sweeney good to know about that one, I ordered some UV Led strip lights to put in a curing box I’m going to build once everything gets here. But I’m just not sure if the lights are really going to be UV 405nm, so nice to know of a backup.

Yellowing is from “over curing” but some resins will get clear over time. It’s difficult getting a clear to stay clear after printing, but there are some newer resins that claim to stay clearer during curing and beyond

Rigo Arevalo LOL, I had the think in there for 4 mins. Didn’t realize that would be to long. But good to learn now!

Looks good!

look like square be out of shape

Kwok Tony what do you mean?

look like square be out of shape, isn't it?

Kwok Tony it looks fine to me in person. Maybe it’s just the pic?

I have this same one and love it so far

Mine is leave the house loud ?

Luke Mason I have a hearing aid in one ear and as soon as I turn on the cleaner it goes crazy and I have to take it out of my ear.

Riika Magnus you can leave prints going for long periods of time, but they can become brittle. Clear resins turn yellow quickly. Try putting it in a clear container of water while curing to help also.

I just fill it with hot water from the tap. It takes ages to warm up otherwise

I've just tried my new cure & wash station & IMO it's the bees knees!

I don't mess with the heater on mine. Be careful, because it probably doesn't have any logic at all - if you forget to turn off the heater, it won't shut off. After all the water evaporates, you have a fire hazard. It almost happened to me once and I'm pretty careful about stuff like that. Luckily I was home and noticed before it was a serious problem.

Micah Vestal good to know, I didn’t even think of that.

John Vickers I looked at that, but it cost more than the Zero so I couldn’t justify it.

Unless I remember to turn the heater on beforehand (that's about a 50/50 proposition) I never have the patience to wait.

I wouldn't use the heater:
