How To Setting Resin Exposure For 3d Printer Resin 

Thank you for your kind words. And thank you to uncle jessy 🥰

Thank you!

Thank you

LOL I always put it to the real life test.

I have to agree! Dennys Wang Calibration pieces are the absolute best! Simple and fast - if the Dennys Wang pieces come out well (the combination of the thicker validation matrix and the custom exposure/support test), prints will not fail! Absolutely vital for successful "unconventional" resins and printing techniques...

I am testing how to improve, Maybe by using other resin. I will share when i have good result.

Thank you

Thank you!

Yes indeed. And also temp and humidity can affect resin exposure

Thank you There will be updated version for exposure tester soon

Thank you

Will do Thank you

Thank you

Welcome! Kindly consider to subscribe Thank you

And the resolution keep getting higher

Thank you

Happy printing!

Thank you

Thank you for testing my exposure tester and let me know your experience using it.

Thank you

For a skin color resin, 60% is ok for a Photon mono 4k ? I did a test with 1.4 s, columns are thick and I barely see the pillars but its 100% UV

would you please share your settings? including UV Power, Cure time, lift speed and retraction speed? I use the Photon Mono 4K

@@renatosilva2078 would you please share your results with 80% and 60% UV Power? I will try soon and do the same.

@@walterrldias I just realized I wrote exposure time instead of UV power to 80. I hope nobody set exposure time to 80 for 1 layer. :D I edited it now. Anyway I tried many to print faster, but it has limits, so right now my prints don't fail with this setting: Layer thickness: 0.05 or 0.1 mm UV power 80 Exposure time 2 sec Lift distance 5>1 mm Lift speed 2-2 mm/s Retract speed 4-4 mm/s (I tried it faster, but it starts to make annoying cured little layers next to the print, so it is the fastest which makes clean prints yet) Important to set the supports thickness to 1.2 mm, I usually print bigger 1/4 and 1/6 pieces, and sometimes 1 mm supports still failed. The connection head of the supports can be between 0.8 and 0.6 mm, depends on the size and details of the printed piece. Good support setting is very important to check them manually if there are too many or not enough placed by the slicer. Print bigger parts with less details with 0.1 mm as figure bases to spare time, and detailed parts with 0.05 mm if you want the best quality look of your printed figure. This setting is not good above 0.1 mm layer height, then you will probably need more exposure time for higher layers. Also the type of resin can act differently, I use the Anycubic grey resin.

@@Chibanah haha I had noticed the typo, but also 80 is such a UV Power number that I decided NOT to bother you with that. I thought u would notice it yourself and you did. Thanks for the feedback. I will try it later in the day.

Welcome! And thank you for watching!

@@wangdennys I'm french, and you speak slowly, so I can understand. It's miraculous :)

I am reading script 🤣 LOL

@@wangdennys Hello, how to print the exposure tester ? Flat on the board, or slightly inclined ? Thanks a lot !

Could message me on my social media With image of the print result?

Thank you

Thank you

Thank you

That means the bottom exposure is overexpose

Welcome

Yes i will make video about support in the future. But for now i am focusing on more basic printer setting

Thank you

Looks like compression issue. Check my sonic mini 8k review part. I show how to troubleshoot it.

Everything is awesome!!!!

Resin printing guidelines? Good one

Yes increase it Also longer rest time.

@@wangdennys What do you mean by rest time? Before curing it? (Btw thank you for the fast answer)!

Check my video after this one About print angle + antialiasing What printer and slicee you using?

It is from RVN minis on patreon.

It's made by kaizen toys on facebook

With my exposure tester I do rerf while lowering the uv power until i have fail This way i can tell the exposure and uv power is optimal. After that i will do stability torture test and print the oval tube to check for print lines. If print lines happen Then i apply lube. Usually print lines completely gone. If your problem is z rail Usually it printed wobble, not just print lines.

@@wangdennys thank you.. very useful info

Latest review is mighty 8k and mini 8k Very accurate imo

It was on mini 4k

Check other video about print angle + antialiasing

@@wangdennys Will do, thank you!

Ok. Will upload it later tonight.

Use aa 2, grey 0, ib 2

Thank you

Singing up for what? The tester is available for free on cults3d.

I print some object flat with phrozen aqua grey 8k resin And not experience any warping. Maybe yoy can try it.

@@wangdennys I'll test some flat to see it it helps, but I also had this issue with thin parts with my Formlabs printer also

10000 hours long video? 😲

@@wangdennys You know, videos where they take tons of time to get to the point and add a lot of non-information. You do the complete opposite and thats why I like your vids :)

@@ravager990 thank you so much for the compliment

I never use lube on fep. It's all about correct setting. Take your time tuning your printer.

Please keep in kind climate and temp can affect resin exposure. My setting Uv power 30% Layer height 30um Layer exposure 1.6s Bottom exposure 20s.
