SUNLU Premium PLA+ Filament 1.75mm, Enhanced Durability and High Strength

I normally use Polymaker or Copymaster3D but this Sunlu was the right colour and it was very cheap. I've thrown away "cheap" filament from Amazon multiple times but thought I'd try this well reviewed filament. I'm glad I did.It prints fast and accurately on my Bambu Labs X1C. The layer lines are well blended and only really show up under harsh light. The finished texture is pleasant enough without the need for additional finishing. The parts I made seem very strong with a .2mm layer height and 3 walls with a simple box-pattern, 15% infill. It adhered without issue to my textured plate without adhesive and stayed stuck until cooled, even with an upside down triangular item (the "point" of the triangle was cut off with the "top" being 3 times as wide).I will look at the rest of the Sunlu filaments for future projects based on the performance of this PLA+.It's also worth mentioning that the spool works well in the AMS, unlike some paper offerings from other suppliers. It's the correct diameter and rolls without issue. The filament also appears to be wound well and accurately onto the spool,

Great PLA filament – very reliable and easy to print with! 👍I’ve been really impressed with the quality of this filament. It feeds smoothly through the printer and produces consistent prints with clean layers and good detail. I didn’t experience any clogging or tangling, and bed adhesion was excellent.The color is vibrant and the finished prints look great. It also seems very well wound on the spool, which makes printing long jobs worry-free.Overall, this is a great value filament and I’ll definitely be buying more for future projects! ⭐

I'm really pleased with this filament. It's been completely reliable from the moment it came out of the pack, with a tidy, even spool that feeds smoothly through the printer. Prints have come out clean with strong layer adhesion, no tangling, and very little warping, even on slightly larger pieces.The finish is tidy straight off the bed, and it feels a bit tougher than standard PLA, which is great when you're printing functional parts or anything that gets handled regularly. Colour was consistent throughout the roll too.If anything, the only slight downside is that certain colours seem to go out of stock quickly, but performance-wise it's been faultless for me. Overall, a solid, dependable filament that I'm happy to keep buying.

Good prints straight from the box

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 it

My Grandson has made some great things with this. Easy to use and flows well

great filament

I bought this as I wanted to experiment with clear PLA+ and was tempted by the price which seemed reasonable.Out the box, I loaded this into my Creality K1 Speedy printer and was able to print a test box with default parameters in Creality slicer (see photos). Where the base is cross hatched, it is more frosted, but the sides are quite transparent.lI did a bit of research and altered the default PLA+ profile to 230c, flow ratio of 1.05 and reduced fan speed to 30%. I also removed infill and dropped the speed to 30mm/s. The 3 test plates are a result of those settings. I made 1 with 1 wall thickness, 1 with 2 wall thickness and 1 with 5 wall thickness. Although it is not easy to tell on the video, the 2 wall version seemed a good compromise between rigidity and clarity.It is best to print this vertically if you want the best clarity, which is how I printed these. I'm sure with a bit more tweaking, I could probably improve on these results.NB: The yellow objects in the photos and video are spacers I printed to use up some filament. I put them under the prints to show more clearly how transparent they actually were.Overall I would say it is good value for money.

Sunlu, très bonne gamme de filament, jamais déçu !
