How To Setting Resin Exposure For 3d Printer Resin

[@Kitzkrieg]

Was under 5 minutes in and I've learned more than any of the other channels I've watched to remedy some of my issues with 3D prints. Also, Uncle Jessy sent me here!

[@wangdennys]

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

[@vision3690]

Hello Mr Wang, you are so knowledgeable about 3D printing. Thank you for sharing your expertise Sir

[@johngundlach1062]

Wish this Video/Channel popped up sooner, would have saved hour, resin and brain cells.

[@arahndoberman2987]

Oh God, I can’t tell you how much this helped me with my first resin printer! I had been using the validation matrix exclusively and suffered from failed prints. Printing your matrix plus the exposure tester fixed it!

[@wangdennys]

Happy printing!

[@zedabyu]

Nice! I just paid for my Mega 8k and am doing some research. This should be very useful. Thanks for sharing, and I hope to learn more from your channel

[@wameier84]

Dude I've been printing for a few years now and your the first person to say that maybe your prints are UNDER exposed! Usually everyone says cut the exposure! I can't wait to print again!

[@vidsurfer0725]

Saw 45 seconds of this video, and I'm a sub for sure....now when I have more time I want to watch all your vids.

[@wangdennys]

Thank you

[@Chibanah]

Not only the exposure time, but also the UV power count in this matter!!! When I turned up my UV power to 80 (the factory setting was around 60 on my Photon Mono X), which is recommended for darker resin, my prints got better even if I lowered the exposure time to 1.5 sec. So begginers pay attention to this as well!

[@renatosilva2078]

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

[@walterrldias]

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

[@walterrldias]

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

[@Chibanah]

@@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.

[@walterrldias]

@@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.

[@blackcanyonmodelworx6060]

Hello from United States. I just found your channel and this is the first video I have watch. THIS is such a huge help. I just got my first resin 3d printer and had 2 failed prints and ruined my FEP. This will be such a huge help to get my settings dialed in. Thank You

[@Vargpung]

Had problems with my elegoo mars 2 pro with setting it up, did some things Dennys told me to in this video and other videos and chatted with him for a bit. Now it works like a charm and the prints are crisp! Love you Mister Wang

[@wangdennys]

Thank you!

[@Emtbtoday]

I have found your test model's on cults and following there aswell, I will be testing all this over the next couple of day's many thanks!

[@volkmen2]

Thanks my man, My nemesis is that, I could only print models of supports. After your video I will increase exposer time.

[@netnoob77]

I have been using your exposure tester quite a lot recently since I just got my printer and have been trying to find the sweet spot with the couple of resin types that I have. I have to say it's a very useful tester model. I usually print the Resin XP2 Validation matrix, Ameralabs town and your tester model together during the calibration. More than once, I found that the Resin XP2 and Ameralabs model to have printed wonderfully at a certain exposure setting but it failed on your tester model (corner support failure). If I didn't print your tester model, I wouldn't have known that the exposure setting was still a tad too low, and that it would probably fail if I were to print a complex model with a lot of fine supports. Also, your tester is quick to print since it has such a low height. For quick test, I just print alongside the Resin XP2 Validation matrix.

[@wangdennys]

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

[@alexwolfang2310]

I'm just starting in the world of printing, and your videos are so good and well-explained. I've subscribed!

[@TreeFiddy350]

Thank you SO much for this!!! The combination of the thicker validation matrix and your custom exposure/support test is absolutely brilliant, the combo of tests has really helped me to understand resin and how far you can push the limits of reducing exposure time.

[@retromodernart4426]

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...

[@mathewfitzpatrick5645]

Geezus! I didn't realize JUST how detailed resin printing could be.

[@wangdennys]

And the resolution keep getting higher

[@cwtjones]

Thanks. This is a genius test piece, to capture the fail print and also very clear result, with no guessing.

[@wangdennys]

LOL I always put it to the real life test.

[@CYMotorsport]

You mentioned the lift screw at 1:14 at I was super curious how you’d assess this but never heard more. The screw is the one thing I haven’t touched troubleshooting and what I’ve been suspecting so to hear someone mention it is affirming. Would there be z wobble and that’s how you’d diagnose this as the screw? I’ve been printing a long time and recently got some very odd fails I’ve never seen with very thin strands of cured resin attached to my object if it prints at all as well as a rectangle in a very thin layer no matter the shape or object I print.

[@nosalis]

those head models looks amazing!

[@Jauphrey]

Holy hell. Amazing video and crazy helpful you absolute legend.

[@3lcost3]

I recently switched to Sunlu standard resin and it's been a hell of a job to remove the exposure tester off the build plate.

[@wangdennys]

That means the bottom exposure is overexpose

[@wangdennys]

Will do Thank you

[@IPrint3dMinis]

This is great, I found in the early days of my 3d printing I simply used the manufacturer's recommended setting for resin type. HOWEVER I quickly figured out that is not enough. I live in FL, and we have a pretty high temp year round, and I also use the printer in my garage with no a/c (yeah it's hot). I run two fans but the common settings seem to cause failures within the print or were giving me heavy print lines. The basic validation matrix seemed to print fine, it was only when I started added supports to complex or bigger prints that caused issues. Long story short, I found a few threads saying that over exposing the bottom layers (from 30s to 45s - given it an extra few seconds for the two layers of screen protector) and pushing up the layer exposure to 3.2 seconds as well as changing the lift speed has all but helped the prints almost 100% print successful now. Good validation matrix too that you made, I will be subscribing for more!

Thanks for the calibration file. I'm dialing in some new resin but the Exposure Tester Model is barely any space between the square and the base. I used the cults3d download but it doesn't look like yours in the video. Using Lychee Pro and you can see the sliced model looks normal. Anyone care to help out? Also ran V3 cones of calibration with table, sword, skull and cones. Was over exposed, beer didn't fit in mug and sword didn't go through skull but I did have all successes and all failures on the cones.

[@wangdennys]

@@theVariedLife calibration model is use only to give you headstart. Fine tune it again on real object print. If there is no space, then that means your leveling is too low and pressing the screen. Relevel with thicker paper.

For the delamination you mean you just leave the print on the plate for 1 hour and wait to see if it delaminates? Or can you remove it for the plate and wait 1 hour before cleaning and/or curing?
