Support material in 3D printing lets us defy gravity, but it does eat up additional filament and add time to the print. My patrons requested a guide on tuning support material settings in the slicer, so this video covers the most important parameters across a range of slicers, as well as ways to apply support more efficiently.

On my Bambu Lab X1C I load PETG into one of the AMS slots, and use it as a support interface when printing with PLA. Works very well, I can set the top Z distance to zero, and the prints come out perfect

@mpark0 Год назад

Can the same be done with ASA and PETG? Or is there another material that can be used to support ASA?

Don't you end up purging tons of waste?

@digital0785 Год назад

@new.one.1307 Год назад

I tried the same but I had a lot of jamming in extruder when PLA was removed. Did you have similair issues?

@dammitmatt6426 Год назад

Very interested in this because I'm currently Z-stacking some PLA to get multiple flat models in 1 go. The bottom layer doesnt matter too much but because it's printing in black, the top layer has a few blemishes where the connection points were. So basically I'm wondering, how clean does PETG leave the top surface when printed on PLA? Since I'm stacking I'm basically just looking to replace the 1 layer gap between models with 1 layer of PETG and then pull it off after.

@Diceman83 Год назад

@TeachingTech There's a Cura 5.3.0 psudo-Alpha that has a critical difference from the current 5.2.1. It is the "Minimum Support Area" setting - in the regular release, this is disabled for tree mode (and defaults to a value too high for me), but the special 5.3.0 release allows it. This was important for me, as I had a small lip that couldn't droop, and I couldn't get the tree or traditional support to go to it due to the part geometry. This version also has a ton of settings for tree mode that help with material usage and strength. Great addition to the tool box if Cura is your slicer of choice.

@genegreiner7766 Год назад

Great video, Michael! Very helpful information. One setting in Cura that is worth using is “Enable Conical Support.” It modifies traditional supports to use less filament by starting with a narrow base on the build plate and building the supports up at an angle until it reaches the full size before the transition layer.

@TeachingTech Год назад

Thanks for the info!

@MidnightMadness3DP Год назад

Since my first 3D printer you have been my go to for knowledge. Your video's are amazing and have taught me so much. I thank you sincerely for all of your contribution to this industry. I might be a bit simple though as I found this video just to hard to follow with all of the jumping back and forth from one slicer to another.

@theycallme_nightmaster Год назад

I might switch to prusa slicer for that paint on feature. making support blockers in Cura is the bane of my existence

@GeorgeWells00 Год назад

Your video has helped me resolve a LOT of issues I've had with supports lately - I have literally printed a dozen iterations of one model and each time it was a failure (usually the supports completely fused to the model, even organic ones). You covered the bases of what is important and how I was very confused with what should be selected for several options in Prusaslicer. Thank you Michael!😁

@TeachingTech Год назад

You're very welcome!

@hyperspeed1313 Год назад

Something critical to know is that the air z gap will always be a multiple of your layer height when supporting a flat surface. If printing 0.2 mm layers, a 0.28 mm gap will print the same as a 0.20 mm gap or a 0.16 mm gap.

@TS_Mind_Swept Месяц назад

Well that doesn't seem to be the case anymore, at least not in Prusa or Orca

@GmoLargey Год назад

Thank you so much, been having some grief with the supports. Where it's needed inside a shell like object, these settings make more sense now.

@maaboo7379 Год назад

Hi, Michael. I have a solution for perfect supports for the single material. The only downside is the number of support top and bottom surfaces which are limited to one's patience (i.e. how many times you want to intervene the print process). The method is simple and kind of derivative of old known method of using marker. I changed the usual marker to the custom one filled with sunflower oil (I purchased empty marker on Aliexpress if someone interested). Then you have to set pause after finishing the topmost interface layer, "paint" the surface with oil and continue to print. I even was able to separate well known calibration cube printed with 100% infill just using pause in the middle, which confirms that 0 mm gap works perfect. Hope, this can help in some difficult cases where you have to print with supports and the surface above support must be the same quality as bottom or top.

@TeachingTech Год назад

That sounds effective. On angled face, do you pause it after each layer to apply the oil? I guess those break away easily by comparison anyway.

@maaboo7379 Год назад

@@TeachingTech Well, technically speaking it's the same downside since angled faces have too many surfaces to support. But, yes, you have to apply oil every layer to make perfect supports.

@somerando8409 Год назад

@Nussbub Год назад

Exactly what I was locking for. 👍🏼 I had some problems with the 0,6mm nozzle

@darrennew8211 Год назад

The paint-on is good for putting supports in someplace that will be hard to reach. Like, if you're printing a cylinder open on the bottom, you can paint-on supports in a ring in the middle of the cylinder, and it leaves plenty of space around the edge and up the middle to get needle-nose pliers to grip the support stuff. Also, if you add extra triangles when you're modeling it (e.g., adding extraneous edge loops in blender) you can very easily paint on the triangles of a large flat area to drop supports right where you need them, not too close to edges and etc.

@Dark0Storm Год назад

The exclusion painting can also be really handy too if you have small areas that you don't want support material in at all as it'll be impossible to remove.

@ac808 Год назад

@bucklogos 11 месяцев назад

For parts I design myself I have gotten into a habit of designing my own supports into the actual part. It's a lot more efficient than automatic supports and yields great results.

@mikejones-vd3fg Год назад

Great info on all the supports. Ive been useing them to my advantage lately, when printing some L brackets for shelf, the little 45 degree diagnal bit gets filled with support adding to the strength of the brakcet, i imagine anyway. Not sure where the compression forces are going to be honest, but more mass in that area cant hurt. Printing the bracket on the side allowed for no support but I was getting warping issues even with a brim because of the small contact and long surface area lifted corners easily (ABS) printing the other way solved that, but gave me unwanted supported which turned out to be wanted! The conicoildal supporst are nice looking too so add an artistic touch to the bracket. Ive also printed some pieces in mid air to be purposely supported which gives a cool effect.

@Dark0Storm Год назад

For xy gap it would be useful to see what effect this has when you are supporting overhangs that are sloped. I found it had quite an effect on removability of the supports, but not really sure what the actual relationship was or when the slicer was using xy, or z gap to determine support location on these kinds of overhangs.

@stephenf98 Год назад

Thank you for a great video. Very educational for this noobie. I took my son's Geeetech A20M since he wasn't using it (just got married working on house) and I'm learning. I would like to learn the different properties for these filaments and how to program into the slicer. Of course there are lots of tuning involved but just the general idea. I would also like to find/told what slicer to use that I can see the G-coding after slicing, so I can edit a few things in like auto bed leveling and/or keep the setting in the EPROM.

@huntliba Год назад

I would add my favorite tip for supports - for PS and similar (I don't know about Cura or S3D) do not over look "support material extrusion width" - I use much much lower/thinner/smaller width for supports, because then they are much much more easier to remove... for example I use 0.6 nozzle and my support material width is 0.4-0.45 (depends on material - silks need little more) and you use less material also :D so win-win

@rubendariovelez Год назад

great video, i would add something, when you are removing the support materialwith smaller Z gap/distance, its easier break the support and then remove the interface support, the interface surface will look cleaner and will be easier than remove all the chunk in unoe move.

@mururoa7024 Год назад

You don't need supports for counter-sunk holes if you design them slightly differently. The STL files for the Voron parts illustrate how to do this.

@Marv3D Год назад

I also like closing them with one layer height, so it's just a bridge and you can simply push the screw through

@alejandroperez5368 Год назад

That's an easy way to design them. But there's an even better design approach out there that doesn't cover the hole and doesn't require supports.

@taza99 Год назад

I've been using the "snug" supports in prusaslicer, just saves some more filament :)

@DennisMurphey 9 месяцев назад

You do a great job and i have learned much. Today I am in new territory. Maybe you have some ideas. CR 10S Pro V1 modified a lot, Pi 4B with Klipper, Mainsail and Orca slicer. Struggling to get clean parts with support. Setting are there but what does what is not transparent. I see weeks of trial and error to learn how to use all the knobs and dials available. Would like to very much shorten that learning curve and try hard to get the best possible part in the fastest print time on this old but much loved Bed Slinger. Any help you can offer would be wonderful, Dennis in Virginia I forgot to mention horizontal holes, I need them for assembly and some are countersunk and some are threaded but that all need to present a round hole not oblong which is most common. I am adding a second part cooling fan to help balance the hardening of filament once extruded. Not installed yet. Should help. D

I had to go hospital Friday because I had to use a raft which I never usually use. I turned it on left it as default and it was really flipping stuck to the point I needed to use something sharp. Unfortunately I slipped now I have a massive bandage on my finger. So I need to check these settings in future to save on hospital trips lol .

@matteoo3923 Год назад

Thanks for your video, really interesting. A thing you should do tough is to focus on just one slicer (Prusa for example? by chance the one i use :D) Switching continuosly from one slicer setting to another makes the video difficult to follow

@photelegy Год назад

❓ 17:07 Is there a way to block the path of the supports? (Support-blockers don't do what I want) E.g. I have a model like your red sketch (10:39) with a small hole in the bottom roof (circle of the hole being horizontal). Now the support would go through the small hole making it difficult to remove. With support-blockers I can try to find the area on the top roof exactly over the hole. What I want would be, that I could insert a "support-path-blocker" (my suggestion for the naming) as a cylinder inside the hole, so that there wouldn't go any support through (doesn't mather if traditional or organic/tree support). For my easy example the way with the normal support-blockers (or paint-on-supports) can work somehow but with more difficult parts such "support-path-blocker" would really help. Maybe they exist and I just don't know where. PS: I'm using SuperSlicer and sometimes PrusaSlicer.

@theycallme_nightmaster Год назад

hard to believe you haven't used tree supports before. I found them within a month of getting my printer and use them all the time, I find they are better than normal supports 60% of the time

@TeachingTech Год назад

It's the truth. With resin printing, they are closer to tree and I have used them extensively, but not with FDM. I don't ever use Cura unless it's for a video like this or I'm reviewing a machine that needs it. With that in mind it was never really an option for me.

@shawnhicks619 Год назад

@@theycallme_nightmaster yeah prusa slicer has it now on the alpha, as mentioned in the video, and it’s much nicer then traditional supports on most items. However Bambu studio tree supports are very nice. I’m sure I could match the results with prusa slicer with some tweaking but I don’t use my older printers as much as I used to so won’t unless I have to. All that being said supports have been the bane of my existence since I started 3D printing. I even kept the first model I printed that is embedded inside support material as a reminder to double check settings. I like the idea that petg and pla don’t play nice and you can use one for supporting the other. I need to try it some time.

@PatrickLangendoen Год назад

You should have said thanks to my support - ers

@rickseiden1 Год назад

If you choose "Smart" instead of "Brush" when applying support enforcers in Prusa Slicer derivatives, you can just click on a surface and the slicer will automatically paint the entire surface.

@TeachingTech Год назад

Great tip, thank you.

@Marv3D Год назад

I can get the best supports by bumping up the bridge flow rate quite a bit, like 1,5. This applys also for the first layer from the overhang printed on the support material. The distance can still be 0,2 mm but with the bigger flow rate the material ist pressen more against ist but still not bonding very well because of the initial 0,2mm "gap". If ther are also real brides in the model I only apply the bigger flow rate with modifiers where the supports contact area is. (PusaSlicer)

I'm amazed that it printed without any issues right out of the box, I was prepared for days of testing and calibration....

@shanematthews1985 Год назад

So what is the option to wrap supports with a wall called in prusa and its derivatives, you seem to have missed those

@thebrain2302 Год назад

Would it work for slicers to have a mode in wich you could print two layers of, let's say, 0.16mm just walls and on the second layer the infill is printed at 0.32mm? This could allow for nice details on the outside and saving some time for infill printing. Also this could already be a thing and I don't know about it. :D

@lshallo106 Год назад

Yes I've heard of that. Look for "combine infill every n layer". Your should find settings for your slicer.

@greenman360 Год назад

I just wish I could get Prusa Slicer to print supports like Cura. I prefer almost everything about Prusa, but when I print things with supports, even using "organic" supports and tweaking the Z distance and X Y separation, they are still harder to remove, much less cleanly. With Cura they almost fall off.

@iamprinceba Год назад

I was curious to know which materials supports adding support to it's prints, from my testing TPUs, PETGs filaments are the hardest and you can't add support at all, this is because of the nature of the material.
