Quite a difficult test print, due to nozzle-dragging toppling the slender structure. Recommend to disable nozzle wipe for that reason. Model: Honey Dipper - A Wave Overhangs Test Model by LeopoldMozart https://www.printables.com/model/1767134-honey-dipper-a-wave-overhangs-test-model
by ja
(this is a marble grey filament, the specs are just part of the 'marbling') The underside surface came out perfectly 'flawless' I would say, and wad dead level until the second layer, which caused the heat deformation and warping. I think an altered pass on the top (lower temp, spaced lines, every 3rd line, then double back , then triple back, or some sort of zig zag back and reverse zag to fill, something that would : 1, reinforce and 2, limit the cooling, could get us a perfectly flat surf
Excellent overhangs. Filament used was 3D-Fuel PCTG
Just a first test with stock settings. Result is a bit rough, but it works. Great work from the devolpers
This print used a custom geometry area to only use Andersons wave overhang slicing on the top gear part. This result in my opinion is perfect - clean functional base, tidier under the gear (compared to a standard slicer which was messy), and no clean-up needed for the gear itself either.
The base of this piece looks mostly good, but you can easily see some irregularities in the top face (compare with the other piece in the picture). When attaching slide-in racks through the notches in the bottom, they wouldn't go in all the way or move smoothly. The gear part itself was successful however.
Part with hexagonal counterbore -- common for seating/embedding nuts. Also addressed in preFlight slicer "Counterbore Bridge Gizmo".
by ja
Hollow cube with a hole in each face, making bridging impossible. Example of opportunistic design with wave overhangs, where this part could otherwise only have been printed using water-solluble supports.
by ja
it failed coz of lack of enough support to the bed and the printer knocked it off on the second layer everything is perfect in the waves a few defects are noted which were due to my filament containing moisture

Reprint of https://waveoverhangs.com/gallery/201 Default settings except "Replace bridge with WaveOverhang" Technically, it's bridged. But the print went wrong at the start (Clogged nozzle detection by the MK4S after 1 min of overhanging) and the surface is way worth than the "normal" bridging
by Nogard
Default settings, Prusa MK4S with Azure blue PLA Prusament, default temperatures. 2nd print of my 1st test print, but bigger and larger. The overhang was absolute perfection (I was watching over the entire overhang print) and after the layer was placed it was insanely horizontal. But it warped because the layer above the overhang was fast and hot. Beside that, 5/5. Note : After the layer was printed, the nozzle moving across the part was wiggling the thin overhang. Careful with long overhan
by Nogard
Default settings, Prusa MK4S with Azure blue PLA Prusament. Default ORCA temperatures, nothing special except slicing and printing. Slight warp of the top hat because it's a small top. 1st test to save on PLA. Next one will be bigger
by Nogard
The Wave Overhangs really transformed this print. It's using Polycarbonate and the material on a BambuLab X1E. You can see the inside with the native BambuStudio slicer on the left and the OrcaSlicer-WaveOverhangs on the right.
by Abhinav
Overall pretty good with a little bit of warping with the only real issue being the inner curve where it seems to struggle to stick to the other waves
by Skull
Superior overhang bottom layer quality, But theres warping that happens on the far edge of curves. I tried with Support, with and without the Auxiliary fan. I think with a bit of tweaking on the slicer it might work perfectly Great work👍 . printed in Elegoo Neptune 4 Pro.
I've increased nozzle temp to 243 celcius and enabled Assist cooling fan to 75%
by czajne
i have some underextrusion.... but its the filament :)
first ever print with this new overhang feature, turned out really well considering no supports were used, everything seems perfect except the slight warping which could probably be mitigated by lowering print temp or wave flow, will run multiple print tests as this projects pretty breakthrough in terms of 3d printing waste etc used completely 0.02mm stock orca preset for kobra S1, only thing changed was in wave overhang category
by Tundranox
Bridge test: 50mm piece with two 3mm legs - 44mm bridging length. On my printer (or at least, with current settings) this is pretty much the max length I can achieve before warping starts to give the bridge a "W" shape. Including two pictures of the same model printed with standard bridging for comparison.
I was trying to solve a very specific problem. Recesses and steps in holes just above the build plate less than 1mm. Too small for support to much to not have drooping. After trying many many different ways i remembered i had downloaded the wave overhang add in for orca and thought i'd give it a try. Though its a small step in a circle, the wave overhang algorithm did a fantastic job and i am now re-designing some parts as this physical\slicer limitation is gone. Oh, i am also using PETG.
by Clemke01
Strings were visible when a line ended and the nozzle moved to the next row. There are also bumps at the start of each row, visible in the 4th photo (on the inner side of the model, on the underside overhangs). Once, a line at the start detached; not sure why, but then it printed normally. Overall, it turned out quite well. However, the surface isn’t great, as defects remain even after three subsequent layers (first photo). I think we can try a regular slicer, but keep the bridge speed at 2 mm/s
by Nataly
model: https://www.thingiverse.com/thing:3215707/makes The overhang printed extremely well with PETG. I can barely notice one tiny line of plastic drooping on the lowest unsupported part of the dish, which is astounding.
Hybrid approach: painted the smallest circle possible in each of warp-prone corners using the paint-on supports function. Using the standard 0.2mm gap the supports leave no trace (5/6 even stayed on the plate) but they're sticky just enough to prevent any kind of warping.
After seeing this https://waveoverhangs.com/gallery/189 I thought the reduced warping might have been at least in parts thanks to the 'thicker waves'. I used some height range modifiers to print the three waves at 0.28 layer height and the warping and delaminations are indeed reduced considerably.
I don't get waves but instead just stacking lines building out. These lines don't print very well. Did I make error with the settings or is my shape to complex for the waves?
by Locutus
I can't believe it printed the overhangs. The top of the long overhangs were a little rough and actually warped upwards at the ends.
by Chew420
The PETG print was a great success! The experimental wave overhangs fully spanned the gaps, and the part shows good layer adhesion with no signs of warping. I did notice a few minor roughness on the corners, the expected rough texture and drooping on the outer edges of layers of the overhang, and only slight stringing in the top edge recess. This is my first try with waveoverhands and overall, it's very viable for saving time & materials, and it looks much better than using supports!
by meadowsjared
The print was slower than anticipated, but the results are phenomenal.
First test with 0.8mm nozzle. Curiously less warping than 0.4mm nozzle. Different kind of defect, where the waves don't fully reach the perimeter.
by ja
Sphere test, almost perfect, better than what I would get using supports. Default wave settings
Test for a decent sized counterbore overhang (20mm diametre inner hole, 40mm external), it's flawless. No warping, no other visible defects. Default wave settings, Elegoo Centauri Carbon, Elegoo PLA+
Almost perfect print on wave default settings (top cantilever actually a little better than same model printed in PETG with supports), Elegoo Centauri Carbon, Elegoo PLA+
Curved_Incline Testing the limits with wave overhangs. From the 3rd revolution onward the errors stack up and result in layers failing.
by Rob
The front saucer came out wonderfully. The underside of the rear thrusters was a bridge; and I didn't try to use wave overhangs instead of bridges. I used minimal supports. Also; to explain for the layer shift, I was trying out a new filament pulley that had gotten snagged a few times.
The print performed very well. I watched the first layer of waves print, and I noticed one side of the waves was drooping slightly lower than the other. They connected fine; and the end result of the bottom layer looks more solid than some supports I've used. It's astounding.
PTSample101 Lots of warping, TPU comes out really rough
by Rob
PTSample100 It seems like the 100th sample is a failed one...
by Rob
PTSample99 Don't know how this one failed so bad. Changing the temperature next sample.
by Rob
PTSample98 Best TPU print so far. Huge amounts of warping
by Rob
PTSample97 
PTSample96 Really good PETG-CF sample, some minor lifting near the edge of the print but looking really good.
by Rob
PTSample95 Don't know what exactly happened to this one, might be underextrusion or temperature too low.
by Rob
PTSample94 
PTSample93 First PETG-CF print. Looking good but has some lifting near the corner

PTSample92 First TPU test, simply failed
by Rob
Sample_91 Trying to find the limit of what is possible with this technique. A1 mini knocked the print off the bed because it kept returning to a position for time lapse

PTSample90 Inclined overhang with a corner. Looks great and wave overhangs handle this really well.
by Rob
PTSample89 Trying different things to remove the lifting in the corner

PTSample87 Tried to see how PLA would handle the same inclined part. The first layer where the overhanging section becomes bigger failed

PTSample86 Even better than last PLA-GF sample, slight lifting near edge
by Rob
PTSample85 Tried to make an inclined and thicker overhanging version of the test prints, only one layer makes use of wave propagation
by Rob
PTSample84 Connection with the base support is better than last slicer version, slight lifting near the edge
by Rob
PTSample83 Tried replicating the best PETG result with the new slicer version, looks great
by Rob
Good print with the K1, only issue is the overhang warps upwards in sharp corners. Fantastic piece of software, will be using from now on
Elegoo Centauti Carbon, PETG. As expected, overhang went up. For a 1 cm overhang to go up 1 mm, it surely overheated a lot. Next time I'll make sure to drop 15-20 degrees from nozzle's default temperature. The printed bracket itself were usable, but not because of precise quality, but because of this level of inaccuracy were acceptable by design.
Elegoo Centauri Carbon, PETG. Circular overhangs are looking pretty good, but sharp edges are flying away up to 1 mm difference from base line to the cut edge. The print itself is successful, this fact alone amase me. But the quality as it is now is not near enough.
by iCpu
print went well. minor warping some surface artifacts from the increased flow and decreased spacing printed in PETG I used default PETG settings
Joystick-Partial_Cut Warping and layer separation at the bottom of the overhang area. Looked fine during first overhang layer. Got progressively worse with each layer on top until enough separation between nozzle and bottom layers occurred so bottom layers were no longer being reheated. The second layer of internal solid infill was horrendous and basically had no support because of the sagging caused by applying the first layer of solid infill. Probably clean enough for my prototyping but not for a finished produ
by bmartin598
Surprised by the first output. Much better than I expected. I will try some more complex parts and on different materials to see what this amazing thing can achieve. Thanks a lot.
endcap Came out perfectly. Sliced on Prusa Slicer, printed on a modified Voron Trident
by surname
Default settings with Andersons algorithm.
t2 Bottom looks good now, but there is some warping. part of it was from overhang layer, but most was from top layers
by Tornad
t1 Start of line seems perfect, but it was picking up material on return move
by Tornad
Kaul 
PTSample79 Tried replicating the same result on a different printer. More warping observed.
by Rob
PTSample80 Lot of warping and rough surface finishes.
by Rob
CustomTesting1 Tried using only the auxiliary fan for cooling on the overhanging section per request. Very straight overhang, only when the pattern is automatically switched to monotonic does it fail. Intralayer thermal gradient seems to be minimized.
by Rob
Pulley The overhang turned out perfect, even after I had a power cut when the hotend was printing the overhang, and it continued without any issues. There is a bit of stringing, but structurally it looks sound. Material used was PC on my creality Hi printer.
by Uddhav
the print is very good keep in mind these extra settings i configured in the filament settings in the images i uploaded
5 best print so far on this is a VERY challenging test print. pattern: zigzag helped a lot against curling up at the end of paths. perimeter overlap: 0.15mm (instead of 0.1mm preset) helped to keep the perimeter wall attached to the wave structure. Hilbert curve floor (2 layers) at 50% density, 20mm/s speed with 0% fan speed showed big improvements against earlier tests (big layer separations after wave). test shows a slight lifting now, could possibly be improved with higher floor density
by fmod
Slight warping and layer separation.
by Gsonz
PTSample78 Only a slight disconnection between the waves and top layer causing a weakness. This issue is known and will be worked on.
by Rob
PTSample77 Only minimal warping of the PETG. Set the minimum wave time to 4 seconds to ensure that the sharp corners are filled.
by Rob
PTSample76 Again almost there, the minimum wave time is just slightly too much as the outer edge starts drooping a bit, changing it to 4 seconds next sample.
by Rob
PTSample75 Looking good, weird texture on the bottom side and slight warping.
by Rob
PTSample74 Good layer adhesion, weird texture on both top and bottom surfaces. Slight warping
by Rob
PTSample73 Monotonic pattern caused print to fail.
by Rob
PTSample72 Slight disconnection between the base of the model and the overhang. Looking good already but needs tweaking.
by Rob
PTSample71 Almost perfect again, slight lifting again, trying a different wave pattern next sample.
by Rob
PTSample70 First successful PLA-GF print, line spacing needs to be smaller to make layers adhere well. Needs more tweaking for more successful print.
by Rob
PTSample69 Almost perfect, just a small amount of lifting filament in the corner.
by Rob
PTSample68 Line spacing too high, line do not adhere well. Also the black ABS is mixed into the base.
by Rob
PTSample66 Good PETG print, filament lifting near the smaller waves.
by Rob
PTSample67 Looks good, only issue is warping. Probably the best ABS will get.
by Rob
Was fairly decent for not tweaking any of the settings, there was warping on all corners however, and there was some weirdness going on between the wave and standard layers. Printed with Sunlu PLA on a Voron 2.4 with an A4T toolhead.
by Ice
PTSample65 Small amount of warping, nearly perfect.
by Rob
PTSample64 More warping than last ABS sample, might be caused by me opening the enclosure during the wave section.
by Rob
PTSample63 Low amount of warping, small amount of lifting near the smaller wave section.
by Rob
PTSample62 Slightly better than last ABS print. Least warping so far.
by Rob
PTSample61 Line spacing a tad bit too much. Layers are seperating. Only slight warping. Ends of the smaller waves stick out again.
by Rob
PTSample60 Slight warping, noticed some curling on individual layers near the smaller waves.
by Rob
PTSample59 Good adhesion, some gaps between the waves and perimeter. Slight warping
by Rob
PTSample58 Very good adhesion between layers. Slight warping, not quite perfect.
by Rob
PTSample56 Good result, only there is a lot of warping present.
by Rob
PTSample57 Line spacing increased too much. Interlayer adhesion is suffering.
by Rob
The first overhang layer looked great, but once printing of the next layer started, the first one got bent downwards. Probably, there were some blobs protruding upwards from the first overhang layer, which then got caught by the nozzle, pushing the whole first layer down.
PTSample55 Looking really good, still a lot of warping.
by Rob
PTSample54 Huge step back from the last ABS print. Looks like underextrusion, will try higher wave flow next.
by Rob
PTSample53 Only problem with this print is the amount of warping observed.
by Rob
PTSample52 Better than the other PHA samples, but still not good enough. PHA warps in a completely different way than the other materials, PHA might not be suitable using the wave overhangs.
by Rob
On the flange the gaps between the holes and the edge are too small to wave through. Some warping also.
by ja
PTSample51 Shape is there, messed up on the perimeter. Material warps a lot even though it looks like it shouldnt.
by Rob
PTSample50 Not good at all, seems like the waves do not adhere to each other.
by Rob
8 good+... relatively low warping. Has gaps on straight sections and smaller features show consequences of warping. The large curve is near perfect
by Tawpie
Default settings
PTSample49 Still not good, very similar to last PHA sample.
by Rob
PTSample48 Line spacing might be too high, as the adhesion between layers is suffering (Classic ABS). Might be that this is printed in an open printer, will try later in an enclosed one. Warping is definitely less than the other ABS sample.
by Rob
PTSample47 It is getting there, still testing settings.
by Rob
PTSample46 First time ABS, printed in open air on the BBL A1 Mini. Layer adhesion is very good, only in the extremities there is some artifacting. Warps a lot though
by Rob
PTSample44 Failed, not sure why yet exactly
by Rob
PTSample45 It is getting there, on the good parts of the print, the curling is extreme
by Rob
PTSample43 Not a lot to say for this one
by Rob
PTSample42 Does not look well at all. It looks like a fly got stuck between two of the layers. Don't know exactly what needs changing yet.
by Rob
030-10 As expected similar results as just no floor layers
by Dennis
030-9 
030-8 Even slower does not really seem to matter
by Dennis
030-7 Results seem slightly better with the slower layers ontop of the overhang layer
by Dennis
PTSample41 
PTSample40 Even more warping caused by the line spacing.
by Rob
PTSample39 Increased the line spacing too much, warping as a result of it.
by Rob
PTSample38 Tried to mitigate the gaps by increasing the perimeter overlap. Might be the best sample so far. Waves are good and adhere well with each other.
by Rob
PTSample37 Even bigger gaps near the perimeter, starting to become a problem especially in the inner corner. Waves once again look nice
by Rob
PTSample36 Bigger gaps starting to form near the perimeter due to line spacing. Waves look nice
by Rob
PTSample35 Print overall is very good, slight warping in the overhang caused some overextrusion in subsequent layers.
by Rob
030-6 Hilbert floor + 30% fan (vs 100% default). Thought slower cooling reduces stress lock-in. However, it warped worse, not better. Hot floor likely sagged into and pulled on the wave during its longer cooldown
by Dennis
Even for cases that can be printed with bridges, result might be better with waveoverhangs.
by Dennis
030-5 60% vs 100% Hilbert curve did not seem to make a difference
by Dennis
030-4 First test with Hilbert-curve settings (https://github.com/dennisklappe/OrcaSlicer-WaveOverhangs/pull/34), definitely some less warping. Will do some more tests and also compare to just no top-layers at all. Will release this later today.
by Dennis
030-3 Tested corner-aware spacing taper (https://github.com/dennisklappe/OrcaSlicer-WaveOverhangs/pull/29) on the small corner, need some more testing to see it's usefulness.

femobook-to-aeropress-r1 I get an error saying vector too long when i try to slice. i cant even get to the point where i try to physically print the model. I have provided the 3mf file so hopefully it'll help you all debug this.
PTSample34 Not quite perfect, quite a bit of warping in the extremities. Between a 4 and 5 I would say
by Rob
PTSample33 Even better than last sample. Warping only near the smaller wave segments but minimal. Tuning line spacing such that there is barely the adhesion to suspend the material mid air might give the best results. However, there are gaps starting to form near the perimeter as a result of the line spacing.
by Rob
PTSample32 Very good sample, increased the line spacing to above 0.4 to 0.42. The only issue on this sample is the warping in the area with concentrated waves.
by Rob
PTSample31 Small amount of layer separation, as seen in photo 2. Minimal warping, only near the smaller waves. On the top side, the waves and perimeter do not properly connect, but can already be seen in the gcode viewer.
by Rob
PTSample30 Not a lot of warping, though there are some spots where there are gaps between tracks and the perimeter (See photo 2).
by Rob
PTSample29 Better overall compared to the last. Warping similar to last as well. The rough surface is less than before.
by Rob
PTSample28 Adhesion between base and overhang weak, line spacing causing issues near perimeter. Warping is less than last sample.
by Rob
PTSample27 The connection between the base of the model and the wave overhang is weak. A wavy pattern can be identified on the bottom and top surface again. Significant warping again
by Rob
PTSample26 First decent PLA-CF print. There is a weird texture on both the bottom and top surface, which could be the cause of too much overlap. Layer adhesion is better than PTSample25. A lot of warping is still observed.
by Rob
PTSample25 Tried with PLA-CF, no layer adhesion at all.
by Rob
PTSample24 Print quality overall very good, the main issue here is the amount of warping.
by Rob
PTSample23 Only a slight disconnection between the perimeter before the curve. Warping is the bigger issue
by Rob
PTSample22 Tried upping the wave flow to see effect. Apart from a small disconnection in the inner corner of the sample, the print looks great. A lot of warping is present though.
by Rob
Noticed underextrusion and simply no connection between the start of the curve in the overhang and the perimeter. A lot of warping present.
by Rob
PTSample20 A lot of overextrusion, very much visible on both the top and bottom. Warping caused the nozzle to interfere when printing the perimeters, causing the sample to fly off the build plate. Accidentally used the wrong filament profile, temperatures were higher than normally used.
by Rob
PTSample19 Rough perimeter and disconnection between waves and perimeter. A lot of warping but shape is there
by Rob
https://www.thingiverse.com/thing:2151369/
by ja
PTSample18 Apart from the same artifact that appeared during the last sample, the print quality is overall very good, a lot of warping is identified.
by Rob
PTSample17 Tried another printer and the new Orcaslicer version for the first time. Noticed a lot of underextrusion with the same converted settings as PTSample 8 and 14. Also a new artifact appeared between corners.
by Rob
Just warping, no delamination. Underside looks flawless
by Cocoanix
multilayerL_04 
Went insanely well but after floor layer was placed it just warped. Will try without floor layers.
by Cocoanix
multilayerL_03 
Basically perfect (dirty nozzle caused black strings in print). I printed this for my youtube video that is in production.
by Cocoanix
multilayerL_02 Very low perimeter quality due to extremely low layer time.
by ja
multilayerL_01 Zig zag behaviour unexpectedly stops towards the end of the overhang.
by ja
PTSample16 Almost perfect, small disconnections between the perimeter, tried replicating the same result as PTSample8 and PTSample14, but with different filament
by Rob
PTSample15 Very similar results to 13, seems to pull back on the material
by Rob
PTSample14 Almost perfect again, wanted to replicate the result from PTSample8, same result is found.
by Rob
PTSample13 Same weird starting lines, looks like overextrusion but the parameters are roughly the same. *PATTERN USED IS "SMART", unlike photo*
by Rob
PTSample12 Weird starting lines, overall not very good quality though shape is properly retained
by Rob
PTSample11 Still shows signs of overextrusion, overall looks clean, nozzle still dragging across the layers.
by Rob
PTSample10 Shows signs of overextrusion, but overall looks clean. Nozzle is dragging across the layers.
by Rob
PTSample9 Shows signs of overextrusion, nozzle is dragging across the layers, causing them to disconnect near perimeter

PTSample8 Almost perfect, not quite, perimeter on a different level than the rest of the overhang
by Rob
PTSample7 Waves not connected to the perimeter on a couple points
by Rob
PTSample6 Waves not connected to the perimeter on a couple points
