How To Get Smooth Surface With Print Angle And Antialiasing

In this video i would like to share some test that i done with several print angles and antialiasing settings.
you could use this as reference for your print orientation and AA setting in order to achieve print result with smooth surface.
Printed on Phrozen sonic mini 4k
Layer height 0.03mm
slice with chitubox
unfortunately per date of this video posted, lyche AA doesnt work after the latest update. So some lychee user that need AA would support the object on lychee and then slice on chitubox.

[@nosalis]

Great video, thank you ! you can definitely lose some small details with antialias / image blur, but if you have the lienes on the model that you would be attemptint o sand down / clean, you will lose the detail as well , so it's really a tradeoff that everyone has to decide for themselves

[@LaRue-1-0]

I would have liked to see a flat print of the tank. It looks like AA and IB make a big difference in any case. The angles didn't seem to make the difference between a good print and a bad print. With his first test model several angles had great results, and many of them better then arctan angle. This was eye opening. For people saying you risk losing detail, when it came to the tank model, I saw no loss in detail between the two at a glance. I think I am going to be giving this a go with my prints. Thank you.

[@wangdennys]

Thank you

[@rossknowles5608]

another good video. thank you. i find the orientation/angles of the print (and decisions about which parts to print separated make such a big difference. ive barely tried the AA and Blur... (first time today). i guess its a matter of using those print layers specs to get the more dense number of layers orientated to suit. (or is it? now i think of it im not so sure the z height is better than the screen mask resolution) the obvious example being a lengthy cylinder such as the tank barrel. super fast print horizontally but far fewer layers...more support needed to keep those lines from sagging. vertical print... more layers, lots more time, plus the risk of waiting hours and hours only to end up with it glitching and getting those 'position slips' seen as horizontal artifacts. hope to see you working through support tactics and all the other little finessing that can be done... although admittedly.. after my first few hand supported prints... i try to minimise it all and save time with some software assistance... lots of factors to juggle

[@mr.prints5783]

Another informative session. Will the test results change for different resins used?? Is it a smart practice to run through the tests you've provided over the weeks for every different resin used? Keep up the great work.

Different resin only need different exposure But print angle and antialiasing setting can remain the same

will this work with the photon ultra dlp? i need advice for getting the photon ultra or the elegoo saturn 2 for dental applications

[@wangdennys]

get saturn 2 or mighty 8k The resolution is better for dental.

[@XxSTOZZYxX]

Will Image blur work on the Mono 4k or is that tied to the aa in the firmware?

[@wangdennys]

I tested mono 4k several times on several slicers. The AA is not optimal yet.

[@NyrixCorp]

Since slicing is always done horizontally, I wonder if the antialiasing is only applied with per-layer information, meaning only X/Y gradients get smoothed. It would be interesting to compare antialiasing with angles on X/Y plane compared to what you show here, which is X/Z or Y/Z plane. Ideally the slicer would pick the optimal grayscale value based on the average of partial deriviatives along both X, Y, and Z directions, but maybe they are not that sophisticated.

[@NyrixCorp]

Nevermind, I thought about it a bit more and realized you only need antialiasing in X/Y plane. Antialiasing doesn't do any magical smoothing of the part, it only allows the creation of sub-pixel accuracy voxels. That can increase the printer's effective X/Y resolution, making it appear more like a smooth surface, but under a microscope it still looks rasterized. The equivalent on the Z axis would simply be decreasing layer height.

[@awildtomappeared5925]

@@NyrixCorp Under the microscope it can look smoother. If the edges were hard then we wouldn't see a reduction in layer lines so they are being softened. The thing is if you do the right exposure you can actually get a layer to form that is too thin to reach the fep, that's why these XY AA methods actually can blur away lines on the Z axis but crudely. For proper Z axis AA you need to compare at least two layers so that you can have a bigger blur on lower angles, I've done this, it works. But for really good Z AA that can actually add detail not remove it you need to do it during slicing by rendering height/depth information with each layer and using that to make a gradient, I'm working on this, haven't tested it yet but I know it will be great.

[@luisbustamante5479]

What is the ideal layer height for best details? Thank you.

[@wangdennys]

I usually do 0.025mm

[@DiavloPL]

How does IB 2 translate to Lychee settings?

[@thirtysixverts]

Hello! I have a Mighty 8k and have been curious about these settings. In Chitubox, I can't set my anti-aliasing level to 0 if I want to do Pixel Blurring. I can set my pixel blurring to 2 as you suggest, but then my anti aliasing must be set to either 2, 4 or 8. I also have a drop down for Grey Level, which can go from 0-8. I'm using the free version. Any ideas/suggestions?

[@msheal666]

Using different printer, but this should work for your as well. Try AA 0, GL 0, IB 2 - it's a best setting for me for now

[@paulocezarxavier8552]

can i keep the settings enabled always? or do I need to turn it off when printing less flat parts. why I think of printing all parts together, whether they are flat or not

Hi Dannys, may I know which printer you are using for AA? I tested with anycubic mono and seems AA not working.

[@alexthehopeless3778]

People always say to shake your resin before using, but when I shake it it creates bubbles and then I get holys in my print which are probably those bubbles, what do you think about shaking resin before printing?

[@herrwolf5184]

let set settle after shaking, also it bubble dont do much problem because it will be squeezed out during printing when the bed presses against it.

@@wangdennys thanks i used to use 0 and 4 will try 0 and 2 now!

[@francisconikotian2326]

but with very complex models its trial end error right? you cant predict everything

[@wangdennys]

For the angle, yes! It is to help you judge on the situation. Usually i judge the situation from the widest or biggest flat surface of an object, and use this method as starting point for the trial and error Rather than go blindly and test every 1⁰ increments. But usually on printer with working AA, it helps alot, even with very complex model. You can check all my test print on video for printer review.
