I saw that Amazon is selling eSUN PLA+ filament. From the product description:
PLA+ Advantages:
Blended with special biodegradeable bio-polyester
High rigidity. Good Glossiness
10 times tougher than PLA
Smoother finished printouts
No cracking or brittle problem
Also, I believe I saw a PLA to PLA+ comparison spec sheet in one of the product images.
Curious if anyone has been using this filament and sees any difference from the non plus PLA that eSUN markets?
So I got some and it is great! It prints just like PLA, probably better than my other eSun PLA. I do a very casual strength test with materials: I print this somewhat flimsy bottle opener and count how many beers it opens before it breaks. So far, this PLA+ is doing much better than regular PLA. I’ll let you know the final results.
That is great news! I would also be curious if the strength translates into the PLA+ not cracking and breaking as it spools while printing. The eSUN regular PLA doesn’t do that all the time, but often enough to be annoying.
I’m printing with a custom profile, but I think it’s just a slightly modified version of the regular Lulzbot PLA profile. I could send it to you if you want, but it just has minor tweaks as I recall (I’m on a Lulzbot Mini by the way).
I have been trying to print this Eiffel Tower .stl that I created for a while with PLA using all sorts of settings. While printing this one section, the constant retraction was eventually grinding my filament and ending the print prematurely! I tried everything with my settings and couldn’t get it to print (it is a VERY hard print too). However, the PLA+ is printing it right now with no issues, so it is definitely less brittle in the spool I would say!
