ColorFabb LW-PLA "The new balsa?"

I want to start this thread for all of us who are playing around with this material to share settings tips and tricks you've come across.

A link to the ColorFabb site.
https://colorfabb.com/lw-pla-natural
https://colorfabb.com/lw-pla-black

And a link to their printing suggestions or how to get some initial setting values for your printer.
https://learn.colorfabb.com/print-lw-pla/

Currently I am printing on my workhorse printer my Ender 3.
Simplify3D Setting I use (YMMV);
Extrusion Multiplier .45 (That's right only 45%)
Retraction (I've given up on that...)
Temp 240
Bed 60
Layer Height .2

I'll leave this as the starting point and post specific findings/thoughts as separate posts.

I've seen this material mostly because of the Eclipson Model-V I'm working on. Been hesitant to pull the plug on a spool because it's a bit pricey. Will be interested to see your results and opinion.

Cheers!

Certainly interested in your findings. I haven't strayed much from normal pla. But just got some pla + to try. If the LW stuff works out I may have to try it as well. Unless it is $50 a spool or something then it would have to be REALLY good :)

Edit -ha ha. I just looked it up. It costs more than that! Hmm. Still watching but that plane better fly itself when you are done :)

Last year I started with the Free plane offer by Eclipson on Thingiverse
https://www.thingiverse.com/thing:3302937#
I have it printed out in PLA, but it seems really heavy... and haven't finished the electronics or maidened it...

Then Flite Test did that video on the EBW-160 (blackwing) and I bought the files for that...
They promptly went on sale the next week... :rolleyes:
I also have that printed out in PLA. This time however I had my new Ender 3 online and I really started playing with the settings to get a good light weight print. All the parts are in a box, so I'm not sure of the weight but it actually feels lighter than the free version (probably end up tossing it...

Black friday and the LW-PLA goes on sale. I buy two spools (might as well with the shipping after all.) it isn't cheap, I'll give you that.

Just this past week I finally started playing around with it.
I used the guide from ColorFabb (listed above) and printed out about 30-40 of these little cubes.

Having things "close" I decided to go ahead and try reprinting the Wing with the LW stuff.
The final parts will print out tonight.

You can see I'm on track for the listed weights as everything you see here weighs in at just 7.4oz or around 210Grams!!!

So where I am currently at on the first spool (after th config run and a couple "extra" parts... did I print wing section 7L or 7R...:unsure:)
So I think I've got enough to try the 3DLabPrint PT-17 as well!!!

The reason I put Balsa in the title was two fold.

First it just feels like balsa in the hand, same kind of woody texture (hard to explain unless you are holding some) and seems to weigh about what something out of balsa might.

The second is on the surface I've gotten quite a few "zits" I believe that's just due to the way this stuff works... The good news is this stuff SANDS! (Just like Balsa)... And layer lines are a thing of the past!
IMG_0151.JPG

As the temp get around 220, it starts to "foam" and I think you would almost want to turn off all software acceleration (but I haven't tried that yet.) This property makes it "string" like crazy... My ender 3 has (currently ;)) a Bowden setup (and that works fine for PLA) but retraction is already at the edge with a Bowen and I just gave up and turned retraction off... The interior of the wings is UGLY, but luckly this stuff isn't transparent!

That is really great info thank you. and very tempting to give it a try. it looks great

Been working on an LW-PLA design. Here's my basic print settings:

Prusa i3 Mk2s

Nozzle: 0.4mm
Extrusion: 45%
Extrusion Width: .43

Retraction: 1.8mm
Extra Restart Distance: 0.08mm
Retraction Vertical Lift: 0.05mm
Retraction Speed 40.0mm/s
Coasting Distance: 0.20mm
Wipe Distance: 5.00mm
First Layer Speed: 40%
Speed: 60mm/s
Avoid Crossing Outline - 150mm

Bed Temp: 55
Nozzle Temp: 245
Cooling Fan: 100% Starting on layer 2

I've got 3 Prusas. They are all stock direct drive, though on one of them, I did a good bit of fiddling with stuff to make sure the filament pathway was perfectly clear. Really, really helps out with stringing. Probably because the retraction movement has almost zero friction.

Great info, thanks. and beautiful plane.
