Wish this Video/Channel popped up sooner, would have saved hour, resin and brain cells.
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!
Thank you for your kind words.
And thank you to uncle jessy 🥰
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!
Thanks, this was really handy and works great. Love the exposure tester model.
Excellent work Dennys. This will save me a lot of time when trying out new resin. I will try it soon.
This is the best informative test print explanation I have ever encountered.. Thank you so much!
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!
Your videos and calibration models are really great. You have really helped me improve my prints. Very much appreciated.
Thank you!
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.
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...
Thank you for making the Exposure Tester model. It is proving invaluable to the new Anycubic Photon Ultra DLP that is reaching backers.
Great Video (again).
your videos are really helpful and your support is simply fantastic. Keep up the great work, much appreciated.
Thanks
Axel
Thank you
I changed from Elegoo water washable resin to a mix of Siraya Fast/Tenacious. I used your calibration tool to set the correct exposure and it worked brilliantly. Thank you!
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!
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
Thanks. This is a genius test piece, to capture the fail print and also very clear result, with no guessing.
LOL
I always put it to the real life test.
Your results look like they couldn't be improved. I'm so impressed. And subscribed. So very subscribed.
I am testing how to improve,
Maybe by using other resin.
I will share when i have good result.
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
Thank you!
Very excited to try this. Just got my printer about a month ago and have been frustrated with occasional print lines. Thanks for this!
Thank you
Thanks! very clear information and I like your test model for exposure testing.
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.
Thank you
Holy hell. Amazing video and crazy helpful you absolute legend.
Thank you for a very informative video. I like the detailed descriptions with examples. This is a big help. My Z axis torture tests showed bad print lines. Following your advice I cleaned and lubricated (using SuperLube) the leadscrew and the guide rail and bearing block. Installed stepper motor dampener and aligned he leadscrew. All this with no change in print quality. The bearing block moves very roughly on the rail so this is most likely the cause. I am waiting for new high quality replacement parts. One question, as a newbie I don't understand how lift speed and retract speed affect the print. I would like to know how to dial these parameters in.
Thanks my man,
My nemesis is that, I could only print models of supports. After your video I will increase exposer time.
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
Great content. Do you mind making video about post printing process (cleaning, curing etc), your prints look incredible! Thanks.
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!
Happy printing!
Great video, I'm new in this hooby and this was so usefull. Thx
amazing video thank you! One quick question what was the exposure time for the burn layers?
You are very kind man to share your knowledge and are a true teacher thank you for your outstanding videoos
Thank you
There will be updated version for exposure tester soon
those head models looks amazing!
Thanks for this. Will give it a try tomorrow
you get a like and a follow.. your 2.5 second layer time was great.!
Different resins and printers all perform differently, always a good idea to do calibration. I was using the original photon for a long time then switched to the mars 2 Pro, the print time is so much faster.
Yes indeed.
And also temp and humidity can affect resin exposure
good and clear explanation . and thanks for the test piece good job.
Your test helped me soo much. May I ask what resin you use? Your prints look amazing.
Super cool video as usual Dennys, let me in the new group! keep it up!
Will do
Thank you
Great explanation! Would love more videos like this!
Thank you
man this was so helpful - thank you!
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.
Thank you for testing my exposure tester and let me know your experience using it.
Geezus! I didn't realize JUST how detailed resin printing could be.
And the resolution keep getting higher
This was a great video, thanks for sharing your info.

Thank you
Thank you so much:) warm greetings from Norway
Thank you, what sort of resin do you use? Looks really nice
this was incredibly helpful, thank you so much!
Thank you
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!
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.
This was extremely helpful!!!
Awesome work very helpful!!!! Do you think you could do a video on supporting large flat objects and getting the best edege? Eg model plane wings or shipping container type stuff? Hope it makes sense.
Yes i will make video about support in the future.
But for now i am focusing on more basic printer setting
I think I definitely got z rod/rail issues. I'll try to change the nfep to be sure and I'll try your test piece on castable resin. Thanks.
Dude, love this test file. Really useful
Thank you
Hey @dennys wang your videos are increadible. My photon mono 4k arrives next week and I have watched most of the videos you have done on it. Im not sure if I have missed it anywhere but how do you decide what exposure power to use?? I saw in one video you were playing with 60% and then another 30%. Whats the thinking behind this
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.
10/10 Video. Beautifully explained. Thank you!!!!!!
Quick question, if the ambient temp is much lower (like now, in winter), should I increase my exposure time to compensate?
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)!
Best channel for SLA
Thank you
i wil try this recomended settings
Very helpful. Thank you very much
Wonderful video sir! Keep up the great work! Can I please find out where you purchase the resin print of Bob Odenkirk? Could you please send me the link? Would love to purchase that sculpt. Thanks again for all the great videos!
amazing work thank you
Fantastic. Thank you!
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.
That means the bottom exposure is overexpose
Very important video. This link should be in every notice. Thanks a lot !
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?
can you share a link to those two heads/busts that you are printing
thanks very usefull videos
Excellent video
very helpful, thank you
I'll download your test model from here Im needing my anycubic mono 4k exposure done i bought the new mono 2 the other day and its beautifully printing but would like to put one of your tests through it anyway!
the validation matrix on my mono 4k i am getting good results everywhere apart from that bar on the right hand side im still getting the layer lines running up that
I will let you know how i get on i might need a bit of help from someone who really knows as i am new and trying to get into the printing hobby
I was just curious where your Sephiroth model came from, I love the stylized genre. Also your video is super informative, thank you.
It is from RVN minis on patreon.
Great video.. but... How does your test show over exposure?
Dennys thank you!!!! This was so informative! I’m struggling with Voxel or pixel lines do you have any videos helping with that?? I’m trying so many different things to fix it but so far have not succeeded
Check my video after this one
About print angle + antialiasing
What printer and slicee you using?
Nice video. Do you find results from calibration matrix different than from your model?
And also. Where did you get Sal’s 3d model? :)
I enjoyed the video. Thanks!
Thank you
Genius! thanks for sharing!
Thank you
Hi thanks for the time you've put into this. I've printed some of your layer exposure pieces, and they are printing without the supports for the rail. The rail is printed fused to the base. Any idea what might cause that?
Looks like compression issue.
Check my sonic mini 8k review part.
I show how to troubleshoot it.
Great content as usual.
Thank you
amazing video!
Thank you very much for the great video! I own a Flashforge Foto 8.9, and I find myself at 3.6 exposure time with little failures on two-three supports. Is that normal? Exposure seems a bit high. At 2.4, the supports were not even printed. Thank you very much in advance. Edit: I tested two different kinds of resins, the Anycubic standard and the Resione EC51.
Thank you, very informative video. Where did you get the Bob Odenkirk STL from please?
It's made by kaizen toys on facebook
Hello, thank you very much for the video, it is very useful, I would just like to know with which printer you carried out these tests, you can see a lot of detail in your prints, was it an 8K?
It was on mini 4k
Off course an FB group will the cherry On Top
I suggest a name Resin Guidelines
Resin printing guidelines?
Good one
This test is amazing, but with the elegoo saturn 3 ultra , with different exopusures print perfectly the test, maybe is the acf, any idea? Or suggestion?
Amazing video even in 2024! Solve all my problems. Can you tell me where can I get Saul Goodman stl? I really like it.
Very good and informative video. Am really enjoying your content. In the Photon Mono 4k review video, you lowered the UV power in order to get better details. How do you know what is the appropriate UV power to get the best results? I think most people will just print at 100% without knowing about this. Also, when you see print lines, how do you know that it is caused by underexposure and not because of the Z rail? Thanks!
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
Hello Dennys, I want to say I appreciate your in depth reviews. In your opinion which of the budget printers have most dimensional accuracy? (Assuming all settings are dialed in correctly) I need a printer that can handle multi parts keying into each other.
Latest review is mighty 8k and mini 8k
Very accurate imo
Great idea and video. I like your tester, but I am unwilling to sign up for another e-newletter/service to get it. So I'll have to continue using other testers. Sorry about that, but I am done signing up for stuff!!!!
Singing up for what?
The tester is available for free on cults3d.
loads of info thanks
Welcome
Awesome video bro , any tips for the Mars 3 4k ultra ? I keep getting voxel lines in my headsculpt prints ? I use chitubox
Use aa 2, grey 0, ib 2
Great video! I will be going through some testing today. A question regarding voxel lines vs print lines. Now that we’ve seen how you get rid of print lines, what should I do to reduce or get rid of voxel lines? Thank you!
Check other video about print angle + antialiasing
@@wangdennys Will do, thank you!
ooo that skin and hair texture at the start.
Love this, can you also share your thicker validation matrix?
Ok. Will upload it later tonight.
thanks !!! from hong kong user
Thank you
I would be interested in that group.
Hi dennys, great video...again.. :) I usually did my exposure test like in your other video, with uv tools and multiple exposures. Would you suggest ignoring this and going forward with the method you showed here? First print matrix and then your test?
On updated chitu 1.9
The multiple exposure not working properly, havent got time to tweak it.
Me personally just print my exposure tester.
The validation matrix in the video is just for reference.
But you could print both if you want for cross check.
@@wangdennys Thanks dennys for the fast answer. Im testing chitu pro 1.1.1 right now, maybe I should try the multi exposure with that. I only used them in 1.8 and since then everything was perfect.
In this case I go with your exposure tester. I had probems with this matrix at first, because from 2.3-2.6 most looked the same, but the prints had lines up until 2.6 (on the mighty 4k at 0.05). didnt have the raised version of you ;)
what do you run on your mighty (if you still run it) at 0.03 as a base exposure time?
Thanks again for making all those videos. They help more than all those reviews.
@@StefanMathys Pretty much the same exposure as in the video.
@@wangdennys Ah yes you are printing at 0.03 here. Thank you very much :)
Very good video and well detailed. Not herp derp, hold on guys before I tell you the problem you have to hear me out, this will blow your mind ... >insert 10000 hour long video< to tell you that X is caused by Y and fixed by just changing Z from 1 to 2... wish all youtube help/guide videos were like this :(
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
Different position on the bed should be tested one single model/position at time, or we can print multiple models at the same time?
thank so much
Hi Dennys, how are you? Thank you for your videos with all that tests. It helped me lot. Am I correct that you use supe rlube to treat FEP? Please correct me..Am I understand right, that you apply superlube to cleaned and dry fep foil and then wipe dry? Then you fill the tray with resin and print your test prints? Thank you for your answer. Best regards Daniel
I never suggest to lube fep with anything.
Lube only leadscrew and rail
@@wangdennys Thanks for the reply and correction. I misunderstood and preferred to ask. 🙈☺️
Does anyone know where to get the files for the head sculpts? I really LOVE the look of them! :o
The video was super helpful, thank you so much!
This is awesome. You are awesome.
Everything is awesome!!!!
What resin, printer and parameters did you use for printing big faces?? Thx
Hi Dennys, great video, been sharing it in a few places.
Did you create the troubleshooting FB group? I printed off your exposure tester as well as the corresponding thick validation prints, going from 1.3, to 2.4 seconds, but I really can't make up my mind. Which would be the best place to post pics of the results?
You can dm my social media
And how do i know what lift and retract speed i need to use? Also the lifting distance etc, i have a M3 and a halot mage, for example on m3 default speeds are 180lift/240retract im using nfep
Great video, when I tried your exposure test (the custom model) the supports didnt print at all and the flat parts were down against the base. Is this a normal fail or indicates some other issue besides exposure?
What printer?
@@wangdennys Elegoo Saturn
