Community prints.

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+

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.

It seems like the 100th sample is a failed one...

by Rob

Don't know how this one failed so bad. Changing the temperature next sample.

by Rob

Best TPU print so far. Huge amounts of warping

by Rob

Very rough TPU print

by Rob

Really good PETG-CF sample, some minor lifting near the edge of the print but looking really good.

by Rob

Don't know what exactly happened to this one, might be underextrusion or temperature too low.

by Rob

Failed TPU print

by Rob

First PETG-CF print. Looking good but has some lifting near the corner

by Rob

First TPU test, simply failed

by Rob

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

by Rob

Inclined overhang with a corner. Looks great and wave overhangs handle this really well.

by Rob

Trying different things to remove the lifting in the corner

by Rob

Slight lifting in edge

by Rob

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

by Rob

Even better than last PLA-GF sample, slight lifting near edge

by Rob

Tried to make an inclined and thicker overhanging version of the test prints, only one layer makes use of wave propagation

by Rob

Connection with the base support is better than last slicer version, slight lifting near the edge

by Rob

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

by Giro

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.

Came out perfectly. Sliced on Prusa Slicer, printed on a modified Voron Trident

by surname

Default settings with Andersons algorithm.

Start of line seems perfect, but it was picking up material on return move

by Tornad

Tried replicating the same result on a different printer. More warping observed.

by Rob

Lot of warping and rough surface finishes.

by Rob

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

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

by MichaelAlbany

the print is very good keep in mind these extra settings i configured in the filament settings in the images i uploaded

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

Only a slight disconnection between the waves and top layer causing a weakness. This issue is known and will be worked on.

by Rob

Only minimal warping of the PETG. Set the minimum wave time to 4 seconds to ensure that the sharp corners are filled.

by Rob

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

Looking good, weird texture on the bottom side and slight warping.

by Rob

Good layer adhesion, weird texture on both top and bottom surfaces. Slight warping

by Rob

Monotonic pattern caused print to fail.

by Rob

Slight disconnection between the base of the model and the overhang. Looking good already but needs tweaking.

by Rob

Almost perfect again, slight lifting again, trying a different wave pattern next sample.

by Rob

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

Almost perfect, just a small amount of lifting filament in the corner.

by Rob

Line spacing too high, line do not adhere well. Also the black ABS is mixed into the base.

by Rob

Good PETG print, filament lifting near the smaller waves.

by Rob

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

Small amount of warping, nearly perfect.

by Rob

More warping than last ABS sample, might be caused by me opening the enclosure during the wave section.

by Rob

Low amount of warping, small amount of lifting near the smaller wave section.

by Rob

Slightly better than last ABS print. Least warping so far.

by Rob

Line spacing a tad bit too much. Layers are seperating. Only slight warping. Ends of the smaller waves stick out again.

by Rob

Slight warping, noticed some curling on individual layers near the smaller waves.

by Rob

Good adhesion, some gaps between the waves and perimeter. Slight warping

by Rob

Very good adhesion between layers. Slight warping, not quite perfect.

by Rob

Good result, only there is a lot of warping present.

by Rob

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.

Looking really good, still a lot of warping.

by Rob

Huge step back from the last ABS print. Looks like underextrusion, will try higher wave flow next.

by Rob

Only problem with this print is the amount of warping observed.

by Rob

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

Shape is there, messed up on the perimeter. Material warps a lot even though it looks like it shouldnt.

by Rob

Not good at all, seems like the waves do not adhere to each other.

by Rob

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

Still not good, very similar to last PHA sample.

by Rob

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

It is getting there, still testing settings.

by Rob

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

Failed, not sure why yet exactly

by Rob

It is getting there, on the good parts of the print, the curling is extreme

by Rob

Not a lot to say for this one

by Rob

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

by Zevilbofh

by Dennis

Even slower does not really seem to matter

by Dennis

Results seem slightly better with the slower layers ontop of the overhang layer

by Dennis

Too much.

by Rob

Even more warping caused by the line spacing.

by Rob

Increased the line spacing too much, warping as a result of it.

by Rob

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

Even bigger gaps near the perimeter, starting to become a problem especially in the inner corner. Waves once again look nice

by Rob

Bigger gaps starting to form near the perimeter due to line spacing. Waves look nice

by Rob

Print overall is very good, slight warping in the overhang caused some overextrusion in subsequent layers.

by Rob

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

60% vs 100% Hilbert curve did not seem to make a difference

by Dennis

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

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.

by ruether

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.

Not quite perfect, quite a bit of warping in the extremities. Between a 4 and 5 I would say

by Rob

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

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

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

Not a lot of warping, though there are some spots where there are gaps between tracks and the perimeter (See photo 2).

by Rob

Better overall compared to the last. Warping similar to last as well. The rough surface is less than before.

by Rob

Adhesion between base and overhang weak, line spacing causing issues near perimeter. Warping is less than last sample.

by Rob

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

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

Tried with PLA-CF, no layer adhesion at all.

by Rob

Print quality overall very good, the main issue here is the amount of warping.

by Rob

Only a slight disconnection between the perimeter before the curve. Warping is the bigger issue

by Rob

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

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

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

Slight warping

by ja

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

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

by ja

Went insanely well but after floor layer was placed it just warped. Will try without floor layers.

by Cocoanix

Good except for warping

by ja

Basically perfect (dirty nozzle caused black strings in print). I printed this for my youtube video that is in production.

by Cocoanix

Very low perimeter quality due to extremely low layer time.

by ja

Zig zag behaviour unexpectedly stops towards the end of the overhang.

by ja

Almost perfect, small disconnections between the perimeter, tried replicating the same result as PTSample8 and PTSample14, but with different filament

by Rob

Very similar results to 13, seems to pull back on the material

by Rob

Almost perfect again, wanted to replicate the result from PTSample8, same result is found.

by Rob

Same weird starting lines, looks like overextrusion but the parameters are roughly the same. *PATTERN USED IS "SMART", unlike photo*

by Rob

Weird starting lines, overall not very good quality though shape is properly retained

by Rob

Still shows signs of overextrusion, overall looks clean, nozzle still dragging across the layers.

by Rob

Shows signs of overextrusion, but overall looks clean. Nozzle is dragging across the layers.

by Rob

Shows signs of overextrusion, nozzle is dragging across the layers, causing them to disconnect near perimeter

by Rob

Almost perfect, not quite, perimeter on a different level than the rest of the overhang

by Rob

Waves not connected to the perimeter on a couple points

by Rob

Waves not connected to the perimeter on a couple points

by Rob

Generally dimensional inaccurate, perimeter on different level, edges not connected

by Rob

Very poor quality, not dimensionally accurate at all, a lot of underextrusion.

by Rob

Very poor quality, not dimensionally accurate at all. A lot of underextrusion

by Rob

Takes somewhat of a form, but still does not resemble the model

by Rob

Does not take form at all. Poor adhesion between layers
