This filament is wound neatly, looks great, prints fast, strong, barely strings in comparison with other filaments, stays stuck to the bed well without fusing with it and is nice and cheap. I would highly recommend this filament due to its amazing price and quality.

eally nice filament like most from sunlu. once iv done the much needed tests eg temperate and flow test the rest of the roll was perfect for me nicely rolled no kinks in it for me and overall printed out awesome

Good layer adhesion with no shrinkage. Good solid colour throughout. Nice clean finish.

Price seems to have gone up from 15.19 to 16.14 overnight though so watch out for price creep.

Happy to switch to this from the ICE PLA I was using.

works fines with my Anet running at around 205 – 218 temps, seen a few reviews complaining about filament not being wound correctly and prints failing to stick I have had no such issues with this. I have now completed 2 x 18 hours projects and 1x 24 hour print with no problems. and to “ledsam
VINE VOICE” Try moving your 3d printer away from the wall so you can move the filament holder to its correct location you might find it prints better also with this design of a 3d printer you might also find a 3d printed spool feed will be a great help so it’s not pulling the filament at an angle.

At first, I had a lot of trouble with adhesion with the Sunlu Filaments on my Ender 3 with the glass bed, and also in a Flashforge with the PEI bed, but they’s print just fine on the blue surface in the Flashforge.

A bit of research revealed that the coating on the glass bed, and the PEI need to be toasty hot to activate the stickiness, and they loosen when they cool. Also, I was using the included Flashforge calibration card. I remembered seeing something about using A4 paper to do this, so I grabbed the nearest piece of A4 and set up the Z axis with that. It happened to be one of those extra thin sheets the NHS send their doctors letters out on.

Instant result. the build plate adhesion issue was solved and nothing even tries to curl at the edges now. I print on the glass bed at 75 degrees for the first layer and let it cool to 60 after that. this results in excellent adhesion and the cooler bed prevents upper layers from pulling the print up, while the initial temperature ensures the first layer has enough time to adhere before it cools. Also, be patient with thin flat prints, let the bed cool down completely with the print held in place before you loosen it, this will prevent warping. It’s the same story with a PEI bed. At first I took the PEI bed out of the printer when down and set it aside to cool quickly. I actually heard the print crack and warp as it cooled too fast!

So far, I’ve used 15 Different SUNLU filaments, Silk, PLA+ and PLA, all have been great and printed perfectly when using the recommended settings (and a nice tight Z clearance) strength is great on all, and no issues with bridging. The only jams I’ve experienced were on the horrible quality Flashforge, which got sent back, no issues yet with the Creality.

PLA+ needs the extra temperature but is a more consistent print with greater strength for it.

First time I’ve tried Sunlu PLA+, not sure I’d buy it again at the same price.

I’ve spent hours trying to stop it stringing on my CR-10s Pro with Hemera XS extruder and I just can’t dial it in. Best I’ve got so far is at 205 degrees with 2mm retraction at 45mm/s but I’m still not happy with the results. Very faint wispy strings that get caught in the fans and annoying bumps in the walls. Can eliminate the stringing at 190 but the result is pretty brittle.

Judging by the pops as it prints there’s quite a lot of moisture in the reel, which probably doesn’t help. Maybe it’s just their way of selling their filament dryers!

Apart from the stringing the finish is ok, nice matt black.

Edited 5th Nov to add 2 stars as Sunlu, after checking photos etc, refunded the cost so I can buy again. As people say, it is not the problems it is how you deal with them, I can recommend them as their customer service will respond quickly and they will fix it. Shows customers and product perception are important to them.
I have other filaments which are 1.6mm near the end of the spool, I assume this is because of tension stretching the filament on the initial windings. Again I guess the filament is warm when wound on as it takes the shape of the spool. In this case as it is a 1kg spool (other were 750g) perhaps the weight caused tension in the final windings too ? I will unwind 10% of the spool sometime and see if it goes to 1.7.
So buy with confidence as they do their best to sort out problems with no arguments. The plasticky smell I believe comes from certain colours, this was silver, perhaps clear will be better.

I have been using ice filament but thought I would try this for a change as the ice went to 1.6mm diameter towards the end. This was 1.7 to start but quickly went to 1.6 !!! Easily seen as it was producing bad layers and the top layers were missing the edges. This is caused by small diameter causing backlash in the bowden tube coupled with not enough filament being extruded. 1.6mm is 10% too small, a massive amount in filament terms. Increasing flow rate to 112% fixes the problem, and confirms the lesser diameter.
Another problem (on the silver one anyway) is fumes. Other makes have never been a problem but I got sore eyes being in the same room when printing. Out of the box the filament smells ‘plasticky’ and more so when heated.
Deserves a star for being flexible (maybe just thinner so bends more 🙁 ) but could have it’s uses. Use in a ventilated room and use a vernier gauge to check diameter before each print and adjust flow rate to suit. Doubt I will use any more as just too risky, no idea what the fumes are.
I will ask amazon for a refund but doubt it is worth returning due to weight, I will return it as long as Sunlu refunds Amazon as not their fault.
Don’t buy it loads better out there. This is my first ever bad review.
Sorry but can’t recommend i
