SUNLU PLA+ 2.0 1.75mm 3D Printer Filament (Red) – 1KG spool

What it is and why people pick it

SUNLU PLA+ 2.0 is a PLA+ style filament for FDM 3D printers, sold as a 1KG spool in red. On paper, the big promise versus standard PLA is simple: tougher prints with less of the brittle behaviour that can lead to cracks. If you’re printing items that need to handle a bit more day-to-day use—think functional prototypes, brackets, or parts that won’t be treated gently—PLA+ is often the midway route between “easy PLA” and more demanding materials.

This is also pitched as a filament that supports faster printing. That matters if your workflow is about getting batches done rather than taking your time on every model. Still, it’s not magic: the speed range is something to aim for only if your printer, cooling and settings are already dialled in.

Key takeaways

If you want a filament that’s fairly beginner-friendly but aims to produce sturdier PLA+ results, SUNLU PLA+ 2.0 fits the bill. It’s described as having good layer adhesion, a smooth surface, and low shrinkage to help reduce warping and peeling. It’s also said to be well wound, so it should load without the usual “tangled mess” stress.

What stands out in everyday printing

The most practical improvements here are about keeping prints stable and keeping the process smooth.

For adhesion, the manufacturer claims reliable layer bonding with a lack of delamination, plus low shrinkage to support a stronger hold to the print bed. In use, that usually translates to fewer first-layer issues than some temperamental materials—especially when you’re printing larger parts where edges can lift.

For speed, the stated print speed range goes up to 300 mm/s. That’s useful if your printer supports fast motion reliably, but you may need to stay on the lower end if your cooling isn’t great or if you notice ringing/artefacts.

There’s also a recommended temperature window (nozzle 205–220 °C, bed 50–60 °C). That’s helpful when you’re starting fresh with a spool, although you’ll still want to fine-tune for your machine and enclosure.

Who it’s for (and who should skip it)

It makes sense if you’re an FDM user who wants stronger-feeling PLA prints without stepping into the complexity of more temperature-sensitive filaments. It’s also a reasonable pick if you’re printing detailed models, functional parts, or decorative pieces and you care about consistent feeding—especially since it’s described as neatly wound and designed to avoid tangles.

It may not suit you if you’re chasing the absolute toughest performance available across all materials. PLA+ is still PLA-family behaviour, so it won’t replace truly high-performance polymers. Also, if your goal is consistently high-speed printing, keep in mind you’ll likely need the right cooling and stable printer settings, otherwise, high speed can compromise surface quality.

Before you buy: checks worth doing

Even when a filament is described as easy to use, it’s worth verifying a few basics:

• Do you have an FDM printer that runs 1.75mm filament?
• Can your setup reach the recommended bed and nozzle temperatures (205–220 °C nozzle, 50–60 °C bed)?
• Are you planning to print fast? If you’re new to speed tuning, start nearer the lower end of 100–300 mm/s and adjust from there.
• Are you printing large or flat parts that can lift at the edges? The low shrinkage/bed adhesion claims are encouraging, but your bed levelling and surface prep still matter.

A quick micro-example: if you’re printing a small bracket or a gadget holder, start with the recommended temperature range and moderate speed, then watch the first few layers for clean lines and good bonding before increasing speed for the rest of the job.

Should you buy it?

Worth considering if you want PLA+ results—tougher and less crack-prone than basic PLA—while keeping the process relatively straightforward for FDM printing. The range of recommended settings and the focus on layer adhesion, low shrinkage, and smooth feeding make it a practical “workhorse” spool.

You may want to skip it if you’re specifically after maximum strength beyond PLA+ territory, or if your printer can’t comfortably run the stated temperature window. Also, if you’re hoping to print at the top end of the speed range with zero tuning, it might leave you disappointed.

Mini FAQ

What nozzle and bed temperature should I use?

The recommended nozzle temperature is 205–220 °C and the bed temperature is 50–60 °C.

What print speed range does it support?

It’s described as supporting 100–300 mm/s, with the filament aimed at high-speed printing up to 300 mm/s.

Is it only for SUNLU printers?

The spool is described as suitable for SUNLU products, and also compatible with the vast majority of other brands of FDM 3D printers (claimed 99%).

Will it tangle on the spool?

The listing claims it’s well wound, designed to reduce tangles, stringing, and jams during printing.
