SUNLU PLA+2.0 3D Printer Filament Bundle, 4KG Upgrade PLA+ Filament 1.75mm, Tougher and Stronger, Dimensional Accuracy +/-0.02mm, 1KG per Spool, 4 Packs, 4KG Total, Black+White+Klein Blue+Red

Arrived quickly. Outer box in great shape. Each package still vacuum sealed. First spool printed very nice. No stringing and no fuzz like some filaments leave. No issues with sticking to the bed or between layers. Color is true black and no problems with the extruded feeding it so size is great. I wanted a few of the reusable spools and these are in great shape, the price per spool was less, and it’s like I’m getting them free without having to print them myself. Win, win for me.

Priced reasonably well. For someone that goes through a decent amount of black PLA, this is a definite plus. Color consistency across batches also seems to be good, so repeatability of prints is easy. Each came packaged in vacuum sealed packaging and a desiccant packet included, good for keep moisture out of the filament. I bought a cheaper roll from a competitor (coincidentally I can't find them on Amazon anymore), and the filament arrived with a high moisture content, messing up my prints. For the price, you can't beat it. Also works well in a Bambu Lab AMS. Would reccomend.

I’ve been running this SUNLU PLA+ 2.0 on a Creality Ender 3 V2 (Klipper, stock motion hardware) using both 0.4mm and 0.2mm nozzles for a mix of functional and detail prints. Most of my printing was done between 205–210°C, which gave the best overall results. I did test down to 195°C with the 0.2 nozzle, but interlayer adhesion dropped off noticeably. At 205–210°C, layer bonding was significantly better than standard PLA I’ve used before. Not quite PETG-level toughness, but much closer than typical PLA. Print settings & performance: I typically run around 175 mm/s with 7500 acceleration. First layer is slowed to 20 mm/s with 0% fan, gradually ramping to full fan by layer 4–5. This setup produced very consistent results. Stringing was almost non-existent. Overhangs came out clean and crisp, and smaller bridges showed minimal sagging. Longer bridges (around 2 inches or more) did show some sag, but nothing outside expectations. Layer height & detail: Most prints were done at 0.04 layer height with a 0.12 first layer, and detail came out very sharp. I also tested 0.2 layer height, which still produced clean, crisp results without noticeable loss in quality. Bed adhesion: Using a stainless PEI build plate at around 45°C, adhesion has been phenomenal. I haven’t had a single print fail due to bed adhesion. Print quality & consistency: Surface finish is smooth with a slight gloss. Color remained consistent throughout the roll. Filament diameter stayed within about ±0.05 mm, typically measuring slightly over nominal (+0.03 to +0.05 mm). Other notes: No noticeable moisture issues so far, even without a dry box. Overall: For the price, this is one of the best PLA+ filaments I’ve used. It prints reliably at high speeds, has excellent layer adhesion at proper temps, and delivers consistent quality across different layer heights. Great option for both functional parts and detailed prints.

Overall I think this Sunlu PLA+2.0 filament is the best PLA that you can buy all around. Price is on the lower end, print quality is great, no clogs or tangled spools after 750 hours of printing with it. It's also incredibly strong. I've gone back and forth between this and Bambu's PLA Tough+ and give the edge to the Sunlu. It's much harder to break and harder as a material itself. The Bambu acts more like PETG where it is slightly softer and though very strong is easier to break than the Sunlu is. The Sunlu fails with a snap whereas the Bambu fails with more of a PETG-like bend. The Bambu is probably better for taking impacts but the Sunlu would likely be able to support more weight before failing. I look at the Sunlu like high carbon steel where it's harder and stronger, but more brittle and Bambu is more of a mild steel. They each have their applications, but with the Sunlu being nearly half the price, I am going to continue to use that for the majority of prints.

If you are new to 3D printing, know that these rolls are 250g not the 1000g that fits in the bambu AMS. These are a great deal, and with the PLA+ 2.0 they filament prints strong. You can print a reel these snap into to fit into the AMS. It’s a great deal and great filament. 10/10 recommend these. Colors are vibrant, adhesion to the print bed is good.

Cheap and still prints as it should. Very pleased with the filament. Will be buying more. No issues with layer adhesion, looks great, standard thickness so no issues there, pretty strong for a PLA.

Im impressed with the consistency and quality of this PLA+ filament; it feeds smoothly through my printer without tangling or clogging. The filament came vacuumsealed with desiccant packets and each spool was clearly labeled, which kept it dry and ready to use right out of the box. Prints using this material have had a nice matte finish and improved strength compared to standard PLA, and the dimensional accuracy has been spot on across all four spools. I appreciate that you get a variety of colors in this bundle, making it easy to experiment with different projects without buying individual rolls. The only downside is that some colors seemed slightly darker than the pictures and I did notice a bit more stringing at higher temperatures, but overall it's a great value for everyday printing.

Buying the bundle is definitely more cost efficient, especially if you print a lot like I do. White is one of my main colors, and I’ve never had any issues with this brand. Prints come out clean and consistent every time, and the filament runs smoothly without giving me problems. If you’re looking for a reliable go-to filament and want to save a little by buying in bulk, this is a solid option.

Super tough and love the colour

So far this has been flawless. Works exactly as it should.

Great quality filament,i would reccomend buying it an i personally eould buy it again,i bought 3 boxes,each box had 500g white and 500g black filament and was vacume packed vacuum packed properly eith silica gel packets and a filament clil with each roll

J'utilise le Pla Sunlu depuis longtemps. Très content. 210° lit à 55°

great
