Good price for 4 rolls. Bought up a ton of their transparent PLA colors recently -- including the white/yellow/orange/purple set here -- and they print well and are remarkably clear. I've had people look at my prints with the clear 'white' (just pure clear color) and say it looks more transparent than PETG. Be aware that their transparent green is REALLY green -- like, neon acid green, super bright.

Anyone else have their sunlu pla just randomly break just sitting there? I have white pla+ and I keep coming to my printer and finding it broken where it feeds in.

SUNLU PLA is being used as a low cost everyday filament, with transparent colors printing especially well and looking remarkably clear, including a pure clear option labeled Transparent. The price for four rolls stands out, and the filament is described as consistent on a Bambu X1C. The main drawback is brittleness, especially with white PLA and PLA left sitting in the printer or PTFE tube, where it can snap at the feed point. Drying may help if the filament has absorbed moisture, making this a practical budget pick with some color specific quirks.

Common Questions (5)

  • PLA can become brittle and snap after sitting in a PTFE tube or loaded in the printer for a long time, and this has been reported with SUNLU PLA and PLA+ as well as other brands. Retracting the filament from the PTFE tube when idle is the main prevention method mentioned.

  • PLA is hygroscopic and can need several hours of drying if it has been exposed to humidity for a long time. In normal use, SUNLU PLA often does not need pre-drying, and some users report going through many rolls without drying them first.

    CoreyR2384GFY_412gabe23111

  • The transparent line is essentially clear, uncolored PLA, and the spool label just says "Transparent" unless it is a colored variant like "Transparent Purple." The transparent colors print well and are described as remarkably clear; the transparent green is extremely bright, neon-like green.

  • White PLA is reported as the color with the most issues across brands, and SUNLU white PLA specifically has been described as giving consistent problems while other SUNLU colors print well. White also needs the most pigment, which can make it harder to formulate consistently.

    DezranCoreyR2384

  • It is described as a preferred filament for the Bambu X1C because it is consistent and priced well. The same buyer also notes SUNLU HS PLA and HS PETG can be bought for about the same price as regular-speed filament.

I've only just started using my existing supply of SUNLU filaments, but they have been good and I like them.

So is the clear white just clear transparent?

This is the preferred filament that I use in my x1c, always consistent and best price ever, however I buy hs pla and HS petg mainly for the same price as regular speed

I've had my filament do that too (not this brand) It'll break in the PTFE tube while it's just sitting there

Sunlu was one of my first PLA. I can't use anything stronger or different for printing so i've decided to try something better, hyper, plus...

Yes, this is a common issue and not just with Sunlu. PLA does something weird when it sits inside PTFE tubes. Moisture absorption, micro fissures, curvature under stress, whatever it is, lots of people experience this issue with lots of different brands. Even my favorite "tough" filament, Polymaker PLA Pro, frequently experiences this if I leave it too long. Retracting the filament from the PTFE tube is, unfortunately, the only way I know of to prevent this breakdown.

Yes. Whether or not I dry. I've stopped buying because it seems I'm the only one.

Wait till you get a printer and have 40 rolls, but can't decide what to print.

So is the clear white just clear transparent?
That's correct. It's "pure" transparent... basically clear, uncolored filament. The actual label on the spool just says "Transparent." (The colors have the color in the label as well, e.g. the label on the spool for the purple one reads "Transparent Purple.") I guess they have to specify "white" so it doesn't look like they made a mistake and omitted the color type.

I find that happens with all my pla+ and Bambu ams when filament sits there for a number of days.

I've had consistent issues with every roll of their white PLA that I've tried, but their other colors have been really good.

For me, this happens with every Sunlu spool, and I'm not sure why. However, there are no issues with filaments from sub-brands of Sunlu, which is weird.
