OVERTURE PLA Plus (PLA+) Filament 1.75mm, Stronger & More Durable, Professional Toughness 3D Printer Filament 1kg (2.2lbs), High Precision +/- 0.02mm, Tangle-Free (Black,2-Pack)

I've been wanting to try PLA + for a while now and decided to try this. I've had an overall good experience with Overture filament.And in summary, this filament has been great. It prints well, and prints produced at appropriate heat and speeds are pointedly less brittle than standard PLA prints. My only gripe is this filament is rather hygroscopic.Diving in to details, again, I've had zero issues with printing with this filament. I've ran this filament through 0.4 mm, 0.8 mm, and 1.0 mm nozzles ( I have multiple printers) and have never had any clogs or adhesion issues, even when I ran prints far too quickly. I also gratefully note that I haven't had any tangles or snags in the filament windings.Returning to my note about heat and speeds, in my limited experience, this PLA extrudes and adheres better at hotter temps. For common PLA, I run a nozzle temp of 200-220 Celsius; For this PLA+, I've noticed better bed and layer adhesion and smoother extrusions at 220-240 Celsius. In terms of speed, I run it about the same as common PLA, with an overall average of 60 mm/sec. I'll go as slow as 20 mm/sec for small, delicate prints and up to 80 mm/sec for larger, rougher prints.Again, I've noticed this filament is rather hygroscopic. I'll be completely honest here; I do 3D printing as a hobby only, so I'm quite careless about my filaments, leaving them in the open on the printers for a week or more. When they aren't on the printers, I do keep them in a sealed storage box but I'm digressing here; With a fair amount of filament from other vendors, I can leave the filament out and only after weeks of leaving it out will I see the slightest sign of moisture in the filament. After only a few days of sitting out, this filament popped, fizzled and even bubbled the next time I used it, there was so much moisture in it.Since this is a result of my carelessness, I won't dock stars for this. But I feel it's worth noting that great care must be taken to keep this filament dry.... Oh, and I forgot to note that I live in a dry, arid region.Finally, to return to my mention of strong prints. Again, this PLA+ isn't harder than PLA, it's actually softer, gummier. This lends it more strength because instead of prints directly snapping, prints that are overstressed will simply stretch, bend and compress until surfaces slowly peel apart, like sticky gummy candy, and/or separate at a layer line.Some time ago, I 3D printed a holding box for a LiFe battery. I messed up some dimensions, so although the box printed well, I couldn't use it. That box was printed from PLA and I decided to see how brittle PLA was. When I smashed it, it literally shattered. Fast forward to printing with this, I printed another battery box, for a different battery, and once again messed up some dimensions. Remembering that I smashed the old box to see how the PLA reacted, I decided to do the same to this new, scrapped box.It wouldn't shatter....Heck, it wouldn't even break any pieces off! The box split across several layer lines, but after several minutes of smashing the box, it was still literally in one piece, albeit split many times. I've got a big project planned that's likely going to use all of this up, but if I have any remaining, I'm going to print a small decorative object and put it outside. I'm curious as to how well this stuff resists the elements. But overall, I'm very satisfied with this filament and will get more as the need arises!

**Second update**Trying to buy more. Looks like Amazon can't keep enough in stock that it's backordered. One of the two brands/filaments I keep coming back to because of how well it differentiates itself from the crowd of competitors.**First Update**Since using up my first spool of Overture PLA Pro (PLA+), I've ventured into trying other brands and other types of plastics including for various reasons (different properties e.g. strength, exposure resistance, colors, cost), and none have been as easy and forgiving to use as Overture's PLA Pro. Prints using other filaments often look as if they have been visited by a family of itsy-bitsy spiders. Even after optimizing for retraction, temperature, print speed; other filaments still exhibit a relatively greater degree of wispy stringing that need post-production cleaning. Overture's PLA Pro has spoiled me rotten with very little to no stringing on virtually all printed parts. As much as I love to tinker, I'd prefer spending more tinker time on design than optimizing extrusion settings; I'm going back to Overture for PLA because I just want my filament to "work."**Original Review**I bought and used this as my starter filament for my Ender 3 v2. As a novice to 3d printing, this is the very first filament I've ever used in my life (I skipped using the short wrap of starter sample PLA filament included by Ender). My very first print ever came out almost perfect using settings that fall within Overture's recommended nozzle/bed temp and print speed (my settings: nozzle 210C, bed 60C, print speed 60mm/s, fan 20-100%). Prints adhered to the glass bed very firmly and were hard to knock over during printing, but prints easily released once the bed cooled down (the trick is to make sure the Ender OEM glass plate is very clean (i.e. clean with rubbing alcohol before each use). Even prints with very narrow footprints hung on (this recommendation does not apply to PETG, which needed an adhesive like glue stick or hairspray for good 1st layer adhesion). If any warping occurred, warping was very minimal and almost unnoticeable; I have not found it necessary to add a brim when using this filament. Adherence was very good, including in overhanging parts printed without support structures. Printed items are surprisingly strong (Overture advertises 5x strength over typical PLA); printed figurines with 15-20% infill resisted a dropped carpenter hammer at 4-6 inches without deformation. That is, prints have high rigidity (i.e. less plastic deformation than PETG), but once they they deform, they don't have much elasticity to return to their original shape and may instead fracture/break. Considering this is a variant of PLA, it's not intended for structural items, but it was much stronger than I expected it to be, very easy to use for a novice, and produced nice looking prints including litophanes. I would definitely recommend.
