This is another great 3D printing tutorial. Teaching Tech is an accurate name for this channel because the pedagogy is excellent. I wish schools taught this efficiently and excellently. Thank you Michael for this very useful information.

[@anon7437]

You can fix the tolerance issue with reducing the xy size compensation by the fuzzy skin thickness. (-0.2 xy size, 0.2 fuzzy skin thickness) this cancels out the external jitter and leaves you with nearly the same tolerance as original

[@ValTek_Armory]

The only problem with that is parts with internal geometry that need to be a certain size to work

[@xenontesla122]

I wish it worked like this by default.

[@DARKredDOLLAR]

X/y compensation is a lifesaver fr. The amount of times I'd have to remodel in cad to get the right tolerance vs just modifying one value is insane.

[@iopfarmer]

Best technical tip in 3d printing in a long time! Thanks 👍

[@Filharvey]

Thanks for the top fuzzy skin info.

[@Dark0Storm]

I use fuzzy skin on very small settings to reduce layer line prominence on tabletop terrain prints. It's nice to see it getting some focus.

[@trulsdirio]

So basically, to make FDM prints look better we don't need to make them less rough, we need to make them way more rough. Neat!

[@seenPunktSee]

For my solution, it even worked on the top layer: I imported my model to Blender, applied the Remesh Modifier, and selected the faces I wanted to be fuzzy. Then, in Edit Mode > Mesh > Transform > Randomize. Worked great, hope it helps!

[@JMMC1005]

I like using fuzzy skin with *very* fine layers, minimal thickness and small point distance. 0.08 mm layers with 0.05 thickness and 0.08 point distance works well, and creates a really nice satin finish. It doesn't make the part feel any rougher than the regular layer lines do, but it does a great job of breaking up the pattern and making the part look injection-moulded. Of course, it's very slow due to the fine layer lines needed to make the effect convicing.

[@oNovais]

This will be so useful increasing surface for viscous glues to hold on.

[@yagoa]

I made a bike handle with the vase mode and fuzzy skin, from TPU works GREAT

[@ArionKrause]

Combining fuzzy skin with point distance of 0.1 mm and thickness of 0.1 along with 0.1 mm layer height and scarf joint seam makes absolutely perfect animal toys, like the Chibimals, as it gives them a light texture and no visible layer lines or seams.

[@cbgslinger]

Thanks for showing how to put fuzzy skin on a top surface! I have been using it with modifiers to good effect, but this opens up new possibilities. It would be even cooler if fuzzy top skin was incorporated into the slicer.

[@waynekiely4137]

Brilliant, thanks. This technique might also be handy to make customisable filters to strain solids from liquids.

[@TheTeknikFrik]

I usually go really low top layer flow (like 0.8) with hilbert curve to mimic fuzzy skin. Will have to try going the other way now :)

[@aleks-ivanov]

I accidentally discovered this effect a while ago when I was experimenting with the Hilbert curve and forgot to change the filament profile, so I printed with PLA at a 245°C. So instead of increasing the flow, I simply heat the nozzle 30°C above the required temperature to achieve the same effect without changing the flow. And thanks to overheating the visual result was even better. The Hilbert curve also perfectly hides lines on the top surface (as well as on the bottom if you don't use PEI surface)

[@torymiddlebrooks]

Thanks, Matt!

[@MertBert]

This was a very helpful and in-depth tutorial. Thank you! I've scribbled down the "Perfect top layer fuzz" settings for future prints Greetings from Norway : )

[@kerasine]

Fantastic video!!! I like what fuzzy skin can do for a print but recognized the limitations. These settings open up a lot more options. Thank you for sharing!

[@fisheye3d1727]

Superslicer is back into production, love the extra controls avail.

[@TheTeknikFrik]

I hadn't noticed it started getting releases again :)

[@AustinVojta]

"All Walls" makes the fuzzy effect on inner perimeters, too (not just the outermost one).

[@James-u9z2v]

Interesting. What would be the purpose of that option?

[@3dPrintsAndLeaves]

@@James-u9z2v Possibly stronger but that would need testing. It's probably there because it was easy to code though :)

[@802Garage]

Top fuzzy texture is awesome! You can actually adjust the fit of one part inside another using only the slicer though. In Cura, horizontal expansion, and in Orca, X-Y compensation.

[@2ndStoryPrinters]

Thanks!

[@JonS]

Great tips! I must try fuzzy skin with that top over-extruding technique. 15:06 You wouldn't need to use CAD to fix the fit. You can use a positive (at least in Orca) X-Y hole compensation in the slicer.

[@TYGAMatt]

I made some garden LED light holders using fuzzy skin and translucent PETG. Works great and diffuses the LED light nicely

[@eiriseven]

That cutting mesh trick is amazing, I was actually going to ask/suggest if such feature existed or would be possible lol.

[@mucokah]

Thanks for the video. It's been like a year since I started to print 3D things. And I'm learning some new stuff each day... How magnificent! I recently started to use fuzzy skin on decorative busts; it looks much better. I was using the default settings of Cura, but reducing the thickness and distance made sense. I'll try today for sure.

[@tomresink7189]

you can also get a fuzzy skin on top (and bottom) by tilting your object 45 degree. depending of you object you can get very nice results

[@hobbyistnotes]

Very cool technique to add top surface texture. I wish we had an opportunity to simply paint the fuzzy skin exactly same way as we do supports in Orca slicer.

[@DaveTimperley]

Yew littly beauty, that is brilliant! I've just got a printer, and I'm planning on making much with the 'fuzzy skin' setting

[@random-staff]

Wow, real mastering fuzzy skin

[@BRUXXUS]

I've been using fuzzy skin with dense distance and lower thickness to print nice diffuser lamp shades from white or clear PETG for a while. That technique for fuzzy skin on top is REALLY cool! I'm totally going to use that!

[@x10iman]

As usual a great tutorial. Thanks.

[@ILIKE3DPRINTERS]

Hi 15:10 you can do it in Slicer, just use X-Y hole compensation to make wall inside the hole with offset If the fuzzy skin thickness is 0.6mm, set the X-Y hole compensation to 1.2mmm

[@Viking8888]

Awesome video! I've been wanting to do some prints with fuzzy skin, so thank you!

[@Vykori]

15:11 hmm? XY compensation has definitely existed in slicers for years, you don't need CAD

[@kurtlindner]

Brilliant idea, Fuzzy Skin as velcro. At the end when mentioning the loss in dimensional accuracy I thought, "TPU." TPU's flexibility could allow for flexible tolerances and accommodate for inaccuracy, and the increased surface area and imperfect surface might increase grip in a press-fit-closure usage.

[@thejoetandy]

top surface fuzzy skin with TPU would also be great for rubber feet and other things that need grip.

[@eddiezebeast]

And this guide just happen to bereleased when I had a print where I which to have more control over fuzzy skin. Thanks Michael! Now I just have to tune the setting to match to the powdered side of my PEI sheet (it's a threaded round box, since both box and lid have threads, they both need to be printed on the flat surface). My guess would be both thickness and point distance to around 0,15mm.

[@craigcolbeck1347]

Great videos; have learned from and use many of your instructions! It stood out to me that you mentioned the complexity of isolating areas of a print in CAD versus in a a slicer (CAM). I see it the other way round. (Not in terms of fuzzy skin on top--the actual topic of the video--but still.) I use (OnShape) CAD for this: I thin extrude .01 in/mm (doesn't matter) inward from the surface where I want fuzzy skin, then I Boolean delete said extrude from the original. I make the new part fuzzy in the slicer. The "internal" surfaces generally don't matter. As useful as the "outside only" setting is, it doesn't work for every model, especially when multiple print heads/components are involved. My post is a bit off the exact current topic, but THANKS FOR ALL THE TIPS, and I hope someone finds this useful.

[@skilledcamman4752]

I was getting really bad results before, Thanks for the video.

[@TijmenHatesads]

I've used the overextrude trick with Hilbert curves for pretty good effect. You can change the shape of the ridges by sanding the nozzle to be more round.

[@ClaytonMacleod]

Bambu Lab should think about creating a wiki that explains all the slicer’s settings. They could even show example pictures. It would save us having to wonder what each setting did.

[@janjager2906]

Yes indeed , a very good idea! It would let you get an understanding of what is going on with those settings so much more intuitive!

[@ydefy1848]

15:00 All you have to do for your fuzzy skin parts to fit is to modify your hole/contour compensation settings. No CAD needed. Of course, it only works on the x/y planes.

[@DrewLSsix]

That 5x.1 pattern looks like it would be great for wood like textures, maybe paired with a wood like filament, or just applied to parts of models that are supposed to represent wood.

[@suit1337]

@4:50 if you use that aggressive thickness values, you need to set the walls to 1 - since the fuzzy skin will intersect with the inner wall and heavily distort the object - i've tested this extensively (also provided a test block set with different values over on my printables or makerworld profile) so no need for "hoping" it works, it works - just use one wall ;)

[@dinissantiago6729]

Vase mode + fuzzy skin could be used to make some sort of filters, could be useful

[@deandavies1462]

IVe managed to get some interesting results when slicing in cura vase mode without fuzzy skin by using different extruder nozzzle settings to the revo nozzle sizes I actually have installled, you get a very interesting finish. I did this with translucent slitter filled fillaments for christmas baubles I was printing. 0.4mm nozzle tricked to thinking it was printing 1.2mm extrusions at a setting I had set up for a 0.8 mm revo printing for a 1.2mm thickness. The end result is something that can best be shown rather than explained in words.

[@ianbruene1529]

You don't need CAD for the tolerance problem if you use the slicer's X/Y compensation settings.

[@yuripolak]

How on earth orca slicer guys didn´t come up with paint on fuzzy... great video

[@kimmotoivanen]

Waiting for Prusa or SuperSlicer to implement it? Do they do feature development?

[@hebijirik]

For fitting fuzzy parts into other parts without CAD work you could try what in PrusaSlicer is called XY compensation. Try setting it to -0.5 when your fuzzy skin height is 0.5mm. I have never used it in combination with fuzzy sking but I have used the XY compensation to make parts slide into parts when they are all scaled down. Parts designed with 0.2mm clearance at 100% size will no longer fit together when printed at 40% size. But if you use the XY compensation on the right ones to increase the clearance that was scaled down then they can be fitted into each other again.

[@KhanTigre]

Amazing video, got my PLA prints looking great. Also, just for the shirt you got my like & subscribe

[@TheLaXandro]

It's weird how there's still no proper texturing for 3d prints. Like, import a depth map, align it on print's surface and it'll emboss a pattern in the part's side. Same idea as fuzzy skin, tugging on extrusions forward and back layer by layer, just deliberately instead of randomly. Texturing is just one thing, it can also be used for text, especially makes stuff easy for date codes and serial numbers as you don't have to bake anything into the STL.

[@abowden556]

This idea is probably more practical with resin printing than FDM printing, at least for the moment.

[@rossmaclean2]

IdeaMaker does exactly that, and you can export it as an STl into another slicer if you wish

[@TheLaXandro]

@@rossmaclean2 that's the thing, it does all this by messing with the model itself, while it should be so easy to do it within the slicing process.

[@iopfarmer]

The one wall type could be an amazing technique to make filters! 👍

[@TS_Mind_Swept]

Not something I'll likely make much use of, but something I'll keep in mind for those times where it may be beneficial

[@piconano]

I felt all fuzzy watching this video.

[@dachi-2]

I made a giant pen holder in vase mode and set the fuzzy skin to be as dense as possible and it turned out stronger than normal

[@richiedeadsix]

Super useful

[@2mD]

@15:05 i think you could just use XY compensation in the slicer, so you don't need to modify the part in CAD

[@ipadize]

15:04 i wish the slicers had an option to offset the walls to the inside like CNC machining Softwares can do.

[@xenontesla122]

Very nice! The fuzzy skin on the teddy bear still looks a little horizontal (I wonder if a higher layer height would help?), otherwise it's perfect! This is really convincing me try it out!

[@hitf5]

When you do a modifier, how do you make it so the connecting part that is not modified does not have a separate perimeter. The example you showed where you placed the modifier through a hole and it split the hole making a weak joint. Sorry I can't be more clear - I tried all sorts of modifiers to not get this line. Basically what I want to do is go from a fuzzy skin perimeter to a normal perimeter without interruption. Maybe slicers can't do this yet though. The reason I like to use fuzzy skin is for that manufactured look others have mentioned. I am usually using fiber filled filaments to help hide layer lines but am tired of being exposed to those fibers so I started using fuzzy skin on normal non-filled filaments to get essentially the same effect but without the nasty fibers.

[@AidanHost]

I’m running into the same issue. I have a model where there are gaps in the wall and as a result the inside of the model gets fuzzy too. Using a Modifier results in two external perimeters, one smooth and then one fuzzy from the modifier on the outside of the model

[@bonovoxel7527]

Oh, noice!! Try this with the Hilbert Curve and maybe 150% instead of 170%. Try or I will have to, this thing is supercool!! Edit: Damn, I'm a genius. I wrote this when you just said overextrusion, lil i know you would have used exactly the Hilbert Curve feature! (It just looked obv to me given the result to accomplish.)

[@throwawaypt2throwawaypt2-xp8nx]

thx to the segment submiters

[@DinnerSonic]

The top surface fuzzy skin effect, wow! I wonder if it'll cause any nozzle damage from bumping into the bumpy bits as it goes around, at least for weaker nozzle types? Also, wasn't there some kind of "use an SVG as infill/surface pattern" trick for one of the slicers out there, could that be used to further customize the top surface in some way with a modifier?

[@3D_Printing]

A Fuzzy ending to this video :)

[@ryan0io]

Regarding Cura fuzzy vase mode, it worked in older versions of cura, but broke in newer ones. I think there was a bug open for it, but last I checked there was no traction on it.

[@eliokreier522]

For fuzzy skin to remain the desired accuracy just use the xy compensation this way you don't need CAD.

[@ipadize]

8:08 this way you could make a bubble creating thing for fish tanks

[@AndroidA258]

you can use XY compensation to make fuzzy skin dimensionally accurate

[@Washierlos]

05:20 this slicer behavior has always bugged me. is there a way to stop the slicer from applying fuzzy skin on the inside part of the model/modifier? as you mentioned, it creates a very weak bond and makes it pretty unusable for some applications. how did it behave in your model of the handle?

[@kdt85]

This can be used to tweak tolerances to. Is something is to loose all fuzzy skin. Printy panels on printable is a use case

[@martinpirringer8055]

another usefule application is when you wrap the part into fiberglass or carbonfiber. Usually you got to hit the part with 40-80 grid sandpaper and scratch it up really good. Wit h fuzzy skin just take the part and lay up maybe a couple of layers of 1708 or such and top it off with a cloth like 6 or 8 oz. So now you got a strong part with as much FG as you want and maybe a mm or 2 of plastic inside. Dont use PLA as epoxy or boat resin gets warm when it cures. But PETG or ABS or HIPS is a good choice

[@alycapo3391]

Do you still sand after fuzzy skin and do you use the default settings. I'm guessing you do a wet lay of carbon and vacuum bag?

[@martinpirringer8055]

@@alycapo3391 Noo sanding and wet layup yes. For the settings it depends on what I use. If its just a covering of very thin cloth like a low oz (4 or smaller) cloth then probably send or very little fuzzy. Problem is that some 3dp plastic does not stick that well especially to epoxy based resin polyethylene sticks better. If you go 1708 or 2408 biaxial you can go with default or even bigger for a good mechanical interface. I dont want to go into materials in general as there are differences between the stickyness of different brands of the same type of material So I consider 2 ways of using 3dp for glassing . 1 for molds then you do mold stuff print as smooth as possible, maybe some post processing, wax, release agent etc and maybe a metal backing or thick plastic mostly petg if you use compression or Nylon if you use heat. Or "consumed" molds with fuzzy skin. Lets say I need a mostly l shaped thing that has lets say 5mm thickness thereabouts. I might print a 1mm thick l shaped plastic with fuzzy skin usually ABS as its stiff and hard on a textured bed with fuzzy skin. Then i might wrap it in 2-3 layers of 1700 biaxial to get the thickness u want and then you can top it off with some cloth and maybe even some standard FG/CF surface finish/paint etc etc if needed as now its a standard layup thing. Now the advantage of the consumed 3dp is that you can be creative in shapes and hole placements and creases as long as you can use layup methods and use a roller etc if the part gets too complicated you do a mold. Like I am working on some intricate pieces for a drive train which are being molded whereas some frame pieces might have lay up and cut to size using grinders, saws sanders drills after they cure etc.\

[@stockvibez]

Not sure why slicers still dont have option to use "fuzzy Z" on top layers, I understand that Z axis is much slower but result could be awesome. Currently for a simpler model, one could make models top surface fuzzy in a CAD software and use nonplanar printing patch for top layer.

After you found a match, my first question is whether you could reduce the flow rate on the top for a closer match to a lower fuzzy skin thickness. Of course, with a teddy bear, the larger thickness is more appropriate.

Newest Bambu slicer update improves the randomness of the texture per layer. It was already good vs Creality 5.1. now its even better. I do .2 and .2 myself with either .16 or .20 layers for a nice "manufactured" look. And DON'T USE ADAPTIVE LAYERS as it makes the texture look inconsistent.
