LW-PLA Prints Falling Over
Hello,
Whenever I try to print something taller and thinner in LW-PLA, it falls over at some point mid-print, irrespective of brim size and lower/higher temp setting for both the hotbed and the nozzle.
Any good pieces of advice in this situation?
Thank you.
Please save your project as a .3mf file

Zip the .3mf and post it here. It will contain both your part and your settings for us to diagnose.
Cheerio,

Thank you for looking into this.

Prosibly this LW-PLA is more fussy than regular PLA and needs to be printed slower ?. See the recommended speeds on this spool : 30-50m/s. Check if the speeds of your profile are within this range.

Foaming filaments are always tricky as they throw away accuracy for volume, they mess with the extruder's internal pressure and there is no easy way to predict where the ooze will go.
Foaming filament of any type should be considered a technical challenge, foaming TPE has a place when the ability to vary the flexibility matters but it's semi-controlled expansion, thermal resistance and changes in strength and resilience mean that it's always going to be tricky to use and newbies should be made aware that it's going need a couple of years experience before attempting it.
Foaming PLA is often described as 'Silk' by cynical manufacturers which deceives newbies into thinking it's just a cosmetic change, it isn't, it should be regarded as a specialist, technically difficult material.
And you are attempting a technically difficult part, that blade has a 30:1 height to width ratio and you are trying to print it standing up - it would be hard to stand it on a desk in that pose.
The first thing to try is printing slowly, very slowly.
Also, add some sort of buttress to keep the part upright, or slice the part lengthways and print the two halves flat on the bed to glue together post printing.
Cheerio,
