Great to see a video on using LW-PLA with Bambu printers. It's also interesting to see the different approaches to designing airframes with LW-PLA. Ideally the part should have little or no travel which would avoid retraction and therefore stringing but I don't believe you can do that with using the standard infill, the internal structure has to be designed for it.

Great stuff guys! Shout out to Tom Stanton as well, his video explaining how to model these vase mode wings is awesome. What do you reckon about using the 50% engineered version with a carbon strut or two for added stiffness?

This! Highly recommended

I would love to see what approach you took in the CAD to make the ribs. Tom Stanton needed to split the ribs to allow for vase mode printing without retracts. From the look of it my guess is that you used 2 layers on the ribs and 1 for the outer shell without the split. I am really impressed with the approach you are taking to get this technology optimized. It will be interesting to see if you use the approach for the rest of the fuselage or just apply it to the wings.

Another fantastic video! Would you be willing to do a video on the actual SolidWorks design and how you create the models?

Why not 👍

Well.. a tenth of an ounce in weight between the Gyroid and the vase mode wing really isn't that much. The vase mode wing was able to sustain a higher load and greater deflection..But an engineered wing like that seems a lot more work goes into that as opposed to just using a gyroid infill. IMO, it seems you get similar performance with the gyroid wing with a lot less work required. Am I reading that right?

@renerosentraeger 2 ай бұрын

Yes

@PrinterPlanes-n8s 16 күн бұрын

This is my take as well. Saving many hours of fiddling in CAD to get 90% of the performance is a fair trade. I am prepping my first design now and have been debating which method to settle on. Now it's clear that, at least for me, gyroid is the way.

Video about wing at last! Thanks a lot. Can you make some additional video about how did you shaped the wing starting from just one particular wing profile? Is a wing just a stack of wing profiles but proportionally smaller as you travel from fusalage to the wing tip? Or maybe something else? And how do you know if the wing generate enough lift to put the whole plane up during project phase?

@rcdavidk 6 ай бұрын

Excellent information. My one concern is about time. Your single wing part reports with a print time of over 12 hours. The only settings I changed on my PlanePrint 6 hour part were the speed settings. At 35 across the board the part went to over 14 hours. I guess there is a trade-off to find some decent print time but with a quality print I can be happy with.

Why did you continue with the infill based solution instead of the engineered wing, if the latter has a higher strength to weight ratio?

@renerosentraeger 2 ай бұрын

Especially when it comes to VTOL Technic inclusion you are too limited with the engineered style. Also inner ductings and smooth surfaces are not possible.

@renereissig-hochweller3228 10 ай бұрын

I saw a comment on one of your shorts suggesting a vtol f 35 I find it a good idea when the jrm 1 is finished sometimes but I think it would be more fun to keep the sukhoi plane body trend going and instead make a vtol su 75 maybe you will take it to consideration when you are looking for a project

How do you like this lw filament compared to esun and others?

@mateoo169 10 ай бұрын

How you test larger grid (trailing edge) when you have alredy broken leading edge ? When you twist wing the tension comes out from the edges of the wings

@mytubehkjt 10 ай бұрын

Great work but like I said, you'll be disappointed with the diamond pattern. It is heavy and you don't need all that internal structure. You're much better to place your own internal structure only where it is required. This can be done without the use of shell or offset face. I'd also recommend you split the wing into 3 pieces so as to have a few horizontal 'ribs'. Best way to achieve this is with adding walls (up to 4) to the bottom 1mm and the top 1-2mm of each section. Lots more here but I feel you guys are reinventing the wheel to some degree...

@marcphilippveenendaal4394 10 ай бұрын

Thanks for your feedback! If you look through the results, the grid pattern was fractionally lighter than the Gyroid and stronger. As we discovered, it is all in the design of the part as to how we can reduce the weight but still maintain strength. It’s a learning curve for us and always better to trial and understand principles so that new ideas can be generated!

@mikekelly6774 10 ай бұрын

It's a shame to see that kind of printer only outputting at 35mm/sec. We buy them to do 10x that speed. Filament makers really need to catch up with the latest printers and produce more high-flow variations.

@zdog90210 6 ай бұрын

Lw pla actually acts quite differently than regular pla. This lwPla foams as it prints so it creates tiny air pockets in the filament as it prints you can increase the rate of air bubbles by increasing the heat, decreasing the extrusion and actually decrease the speed it is printed so by printing more slowly around 35mm/s you can maximize the foaming action of that filament with the heat of the nozzle by giving the filament more time in the nozzle tip thus lightening the overall part. Plus the parts are a single wall in vase mode they print pretty quickly. Other lwPla is prefoamed and those are printed closer to petg or abs speed but not nearly as light as non prefoamed lwpla

@colesantos 6 ай бұрын

stock settings dont work at all for lw pla on a bamboo x1. poor layer adhesion and completely weak parts. messing with settings helps a bit but basically garbage compared to pla strength. not sure if others have this issue.

Yes, took some time to figure out and finally it works perfect.

he mentioned Light Weight PLA. It's the more expensive one that foams up. Weights about 50% of regular PLA

@rv7builder397 2 ай бұрын

The strength is impressive (I think), but there's no actual frame of reference, and the test method doesn't offer any insight into the strength required (which is driven by load distribution on the wing), vs the weight. If you want to design the lightest wing for the strength required, the testing should be with a 'Whiffle tree' to properly distribute the loads to match flight loads. (Look it up; I can't seem to embed links in youtube comments.) Having said that, I really appreciate the video showing the use of the LWPLA. Looking forward to trying it with the grandson, who's into both 3d printing and RC a/c.

@@renerosentraeger Hey, I just realized that the 1st search results you get might not accurately describe using a Whiffle tree for wing testing. The Wiki link talks about equalizing the load, but when testing a wing, aero engineers test based on the aero loading of the wing, which is very high at the root and tapers off toward the tip. The tree is adjusted so that the inner part of the wing carries most of the load, tapering off toward the tip, as happens with the wing actually flying. A 'wing sandbag testing' search and clicking on the images tab will give a much better visual of what the loading looks like.
