Lightning infill is new in cura 4.12 beta. But what on earth is it?

Күн бұрын

So, as the video says, after my monumental 10 day marathon and before I fix my broken printer (yes, yes, you all want me to fit a DD...don't worry, I'm on it!). Where was I? Oh yes. I had to reinstall windows and all the other stuff, and noticed that cura was a new version. Seriously, how did I not see that? Must have been too busy making content!
Lightning supports though. I actually think they're pretty huge. In case you hadn't gathered that.

I've printed a number of large pieces for a model ship so far using lightning infill, and the hull so far has printed perfectly and almost completely hollow - the end result is a perfectly structured piece that isn't brittle but weighs much lighter that printed 20% faster with 80% less material. (80% may be exaggerated, but its ALOT of material saving)

@@walterkennedy9474 I used 20% infill with 3.2 line distance which I think is default, had no problems with this. Print speed 50mm/s and 35mm/s wall, t/b and support speed. The keel prints better perpendicular to the build plate to minimize visible print layers, so angled 90 degrees as if the bow is pointing straight up. Obviously cut your pieces into parts that require little to no support if possible. Suggest a resin printer for small detailed parts and decorations.

Seems very logical, although why it's a type of infill I don't know. It seems that "Internal Supports" would be a valuable new category that is actually orthogonal to Infill. I can see using a Grid or Gyroid for structural strength and still wanting to run this "lightening" algorithm (or some other internal support algo) afterwards to improve the support of minima. Still, good progress!

It's not exactly what you are describing, but gradual infill gets pretty close, although it's denser under any top surface, not just those that really need it. But if you subdivide it 1-2 steps, you use half or quarter infill density in the rest of the internal volume :)

I have seen this comment a lot, it makes sense on the face of it, but I find it doesn't seem to happen in reality, the infill is so thin. Of course it could be countered with more bottom layers if it was an issue, say if you were printing a human head or something. I had a horrible idea about using it to print stacked dice. 🤣

I would love to be able to combine this lighting infill with a very minimal, maybe 5% line or grid infill. I feel like the combination of the two would give you a perfect balance of support in exactly where it's needed and rigidity.

@bymitten1 2 жыл бұрын

If you haven't already, you could try using the "gradual infill" setting in Cura. If you set the infill density to say, 25% with three "steps", it'll print the majority on the model at 6.25% (25 ÷ 2 ÷ 2) infill, followed by 12.5% and then 25% for the last 3mm.

If you use the default 20% infill and just set "Gradual Infill Steps" to 2, you will get 5% infill for most of the volume, and 20% in a thin layer just below all the overhangs where it's needed. I prefer that, because bigger objects are not very rigid with "Lightning".

Yeah gradual infill steps are good for things that need to be less flimsy that you know where they will be loaded from. I made a stand for something and saved a ton of plastic by doing that. I mostly do functional prints so I don't think I will have much use for this new infill as I typically need a strong part from all sides. However, it's always super cool to see the advancements in 3d printing just from the software side, and this very clearly will help reduce filament usage and print times for prints that can take advantage of less infill.

@jmunkki 2 жыл бұрын

Another take on this would be what you might call spiderweb internal support. It looks like lightning support still starts from the bottom of the print and I can also see that it's often not connected at both ends. Instead, spiderweb support would leave the bottom of the print empty and start bridging across the print before the internal support is needed to build a net on top of which more dense structure can be built (still supported by strands from the side of the print). As a designer, I like to make models that have supports in the model instead of relying on slicers. Similarly, for an isolated local minimum in a top surface, you can hollow out the model below it to create an invisible internal pillar.

@jeffwells641 2 жыл бұрын

It looks like it does both from the bottom and/or from the nearest stable surface. It probably looks for the most reasonable spot to put support, and if it can't find a nearby internal surface that is flat enough it will just use the bottom surface, which seems reasonable. Webbing would need another available surface to attach to, and it won't be able to web across layer boundaries (e.g. a spot on layer 15 to a spot on layer 25), so anywhere the print struggles with bridging webbing will also struggle. It doesn't seem like it would actually solve a problem except to maybe give a small amount of overall support.

@TarekMidani 2 жыл бұрын

If you branch out at 45 or 60 degree angles you can basically be able to start the infill higher off the ground without requiring bridging. Maybe we need an option to specify to the slicer at what angle we're confident the printer can handle. Or what length of bridging can it do

To make structural parts, I'd ditch the 0.1 millimeter nozzle because I'd be working with materials which would invariably jam it. I would also add Load-Dependent Infill to the mix, and I'd do a crapton of tempering and annealing.

Big fan of your explanation and I do believe it makes a lot of sense. However, compared to other common infill methods I can see two caveats: - lightning support assumes an orientation of the part. Unless the parts intended orientation of display is the same as when printing, the internal support becomes “useless” besides improving printing surface quality (not a problem for decorative parts). - Compared to uniform infills, this also impacts the weight distribution of the model by shifting the center of gravity more to the top. It is a great tool, but there are some trade offs.

Really neat; I don't know why I didn't think of "internal trees, why not?" before now.

I know, it's definitely one of those "why did this take so long" moments.

I agree there hasn't really been enough improvements in support (internal or external) in the last few years. I blame s3d for being a paid program that a lot of influencers got that worked better than anything out (at that time) but then NEVER got updated. Now that the free software has the same features and more I haven't looked back at the software I paid as much as a cheap printer for...

Ok when I first heard about the new 'infill' I was not at all impressed nor did I realize what it was truly for. Wow..that's useful.

Great content and do agree! Can you print with lightening. Leave a hole to inject expanding foam. I bet u will be finished with an very strong part simple to make

You could. I'd be interested to see how well that would work especially on really large pieces

I almost never print hollow parts but this features seems like a huge game changer for those that do.

This is amazing I was just thinking about this a week ago. About why is there no version of tree support for infill. I'm so excited I just updated cura.
