SUNLU’s PLA+2.0 Filament Bundle Review: Speed, Accuracy, and Colorful Vibes

SUNLU’s PLA+2.0 filament bundle is pretty hard to miss—eight spools, eight bold colors, each vacuum-packed and promising more muscle than your average PLA. It sounds like a dream for anyone juggling class projects, prototypes, or just a lot of ideas needing a splash of color. But, hang tight—there’s more going on beneath those shiny wrappers.

Let’s start where SUNLU loves to boast: speed. The label talks a big game about printing up to 300mm/s. Sure, it moves fast, and for cranking out parts last-minute (don’t act like you haven’t been there), speed is gold. But it’s not all smooth sailing. Push it too far and you’ll notice stringing—those annoying wisps that ruin your prints’ clean lines. Tuning your slicer and dialing the temps is basically required homework if you want the speed without cobwebs. Otherwise, be ready for some post-processing or those infinitesimal jams that eat away your patience.

Accuracy-wise, their claim of +/-0.02mm dimensional tolerance is decent enough for student projects, models, and most functional parts. Print settings dialed correctly, what you ordered is mostly what you get. The “plus” in PLA+ means it’s less fragile than garden-variety PLA. You can flex finished parts just a bit more before that heart-sinking snap. Still, as those spools wind down, the last bits might get a little sketchy and brittle. Not a crisis, but it’s worth knowing—nobody likes surprise spaghetti, especially when you’re short on filament.

Colors? The rainbow spread is genuinely handy—blueprints and renders come to life, and everything’s easier to organize. It makes presentations pop, or at least lets you fake some artistic flair if your skills end at ‘functional but ugly.’ But heads up: the color that trips people up most is black. For whatever reason, it wants its own bed and nozzle temp, and it can turn out weird and dull unless you fuss a bit with your setup. If you’re matching existing parts or need consistently popping finishes, one less thing to troubleshoot would be nice.

Packaging gets a thumbs-up. Each spool is vacuum-sealed, which means you avoid that sickening sizzle in damp weather. Feed issues are usually minimal—the company seems obsessed with neat winding. But not every roll arrives as a perfect coil. Occasionally you’ll discover a sneaky loop underneath, and one tangle means a session of panic surgery mid-print. For folks who hate babysitting their printer, this is the kind of surprise nobody wants right when a deadline looms.

Temperature matters, too. The window for a good print—205°C to 220°C at the nozzle and 50°C to 60°C at the bed—isn’t huge. Drift too far (or don’t double-check for each color) and you can run into curls, layer split, or outright failed adhesion. If you’re the type who just wants to load and go, something less finicky might serve you better.

So, who’s this for? If you like tweaking, experimenting, and are willing to play print-whisperer for better results, SUNLU’s PLA+2.0 bundle will give you a lot to work with—strength, color, a touch of speed, and the flexibility to try new ideas on a whim. If, on the other hand, your priority is unboxing a spool, loading it, and forgetting it (especially for long or mission-critical prints), I’d point you toward something more forgiving. The occasional stringing and tangling, along with the personality each color brings, add up to some extra work.

Bottom line: SUNLU PLA+2.0 is versatile and fun, but not quite plug-and-play. You’ll get value for the bundle and plenty of variety for prototyping, but you’ll also need to keep an eye on the details and be ready to troubleshoot. If you’re up for it, great—otherwise, keep browsing for a more hands-off filament that won’t test your patience when you’re in a crunch.
