SUNLU PLA+ 2.0 1.75mm 3D printer filament (PLA+ upgrade), Grey, 1kg spool

The essentials

SUNLU PLA+ 2.0 is an upgraded PLA+ filament for FDM 3D printing, aimed at people who want parts that feel less brittle than “standard” PLA. On paper, the brand positions it as tougher and more crack-resistant, with layer adhesion and low shrinkage designed to help with dimensional stability and fewer warping headaches.

It’s also a filament that’s meant to be usable day-to-day. If you’re printing functional bits, prototypes that get handled, or even decorative pieces where you don’t want them to feel fragile, PLA+ tends to be the sensible middle ground. Still, it’s worth remembering: PLA-based materials are generally not the same as true engineering plastics when it comes to sustained heat or harsh environments—so it’s not a “set-and-forget” choice for every demanding job.

Key takeaways

The most compelling angle here is the combination of strength-orientated PLA+ behaviour and practical print settings. The entry lists a nozzle range of 205–220°C, a bed temperature of 50–60°C, and printing speeds of 100–300 mm/s, which suggests the filament is intended to cope with faster workflows rather than only slow, delicate passes.

There’s also an emphasis on clean handling: a “neatly wound” roll, plus a low chance of tangles and jams based on the consistent spool winding. For anyone who has had filament turn into a knot of regrets mid-print, that’s not glamorous—but it matters.

And for people tracking tolerances, the listing includes dimensional accuracy of +/-0.02mm. That doesn’t automatically guarantee flawless results in every setup (printer calibration still rules), but it’s a useful promise if you care about fit and precision.

What you’ll notice day to day

Layer adhesion and consistency are usually where PLA+ either earns its keep or disappoints you. This filament is described as having reliable layer bonding, a smooth surface, and reduced delamination. Combined with the stated low shrinkage, the goal is fewer deformations and less peeling away from the bed.

If you want a quick example of how this plays out in real life: imagine printing a small latch or a bracket that’s meant to be flexed a little during assembly. With PLA+ that’s positioned as tougher than PLA+, you’re hoping the part holds up better than a more brittle print would—particularly at stress points around corners and thin features.

Where it shines (and where it may not)

This is a good fit if you prioritise stronger-feeling PLA prints, better resistance to cracking, and a filament that’s compatible with both everyday projects and higher-speed printing. It also suits beginners as a “reliable and easy to use” option, provided you follow the recommended temperature and speed ranges.

It’s not the best choice if your parts will be exposed to conditions where PLA materials typically struggle, or if you need an engineering-grade polymer. Also, while dimensional accuracy is mentioned, real-world precision still depends heavily on your printer’s calibration, enclosure conditions, and how well your settings match your specific hardware. If you’re expecting it to fix poor first-layer adhesion by itself, it may leave you disappointed.

Compatibility & requirements

The listing claims broad compatibility with FDM printers, driven by the spool’s shaft size being suitable for 99% of other brands. Beyond that, you’ll still want to match your printer’s capabilities with the typical PLA+ temperature range (nozzle 205–220°C, bed 50–60°C) and ensure your slicer settings align with the stated speed guidance.

Is it worth it?

Buying verdict: this SUNLU PLA+ 2.0 spool looks worth considering if you want PLA+ that leans tougher than more brittle baseline PLA, with settings that support relatively fast printing and a focus on layer adhesion and low shrinkage. It’s especially attractive for people printing functional prototypes, parts that will be handled, or projects where you don’t want to babysit warping and peeling.

You may want to skip it if you’re printing something that needs high heat resistance, or if you’re buying purely for precision without checking your printer calibration—accuracy claims don’t replace good setup. In short, it’s a practical “workhorse” PLA+ option for FDM owners who like their prints to be sturdy, but it can’t magically turn PLA limitations into engineering-plastic performance.

Quick FAQ

What are the recommended print temperatures?

The listing recommends a nozzle temperature of 205–220°C and a bed temperature of 50–60°C.

How fast can you print with this filament?

It’s described as supporting up to 0–300 mm/s, and the suggested speed range is 100–300 mm/s.

Is it good for accurate, precise prints?

It claims dimensional accuracy of +/-0.02mm. That’s a promising figure, but accuracy still depends on your printer and calibration.

Is the spool suitable for most FDM printers?

The listing says the axis size makes it suitable for 99% of other FDM printer brands, but you should still ensure it fits your spool holder.

Is this filament mainly for beginners or experienced users?

The wording suggests it’s approachable for beginners while still being “reliable” for experienced users—so it’s more about consistent print behaviour than complicated tuning.
