PVPLA175WT PrimaValue PLA Filament, 1.75 mm OD, 1 kg Spool, White

This was my first cheap filament, and it hasn't been a terrible experience. Other comments had me concerned that there would be all kinds of issues. I believe these could be valid, but none of them were present on my Wanhao Duplicator i3 Mk2. Measuring the thickness of the filament did show variation, from 1.71mm to 1.8 in some places, from my understanding this might cause problems with the extruder, but at the time of writing this review I have now on my third spool with no obvious issues. You really do get what you pay for as far as I am concerned, and in this case you shouldn't expect the best quality, but if you're using the lower end 3D printers, I can't see any problem with using equally low-end filament. I have since tested some £20+ filaments, and you can tell they're better quality, but not everybody can afford to pay for more than one spool when they get their first printer, and this is the perfect filament for any such people.

"Perfect roundness and very tight diameter tolerance". I would disagree with this completely. I have had a print completely fail now due to a complete lack of quality control. My extruder had stopped working because the filament got stuck, it had a bulge in it that failed to get into the extruder. For 1.75mm filament, the bulge was 2.4mm, so quite a big difference. Won't be using this filament again.Now not sure if I have any more, so afraid to use it for large prints. Considering I have 3/4 of a roll left, this is complete waste!

My settings on an Anet A8 modified with bowden extruder all metal. Hotend 180C any hotter and it strings. Bed 60C Retraction is high on this one. Retraction distance 5mm Retraction speed 80mm/s It's a good stable filament, adheres nicely but I find it strings more than most. I have tried three brands of white so far and another brand called ICE is my favourite for consistency and less stringing!

It's an OK filament but nothing to be amazed with. It likes to print around 195C but I find it much harder to use than Hatchbox filament. It's just my opinion but for a newcomer (like me) this filament will be tricky to start with.

I'd been using RigidInk filament for a couple of months, but saw this suggested on My Amazon. To say it's that much cheaper than RigidInk, I was really pleased with the prints I got with this filament. I'm running a hacked Chinese Prusa I3 clone with a bowden and E3D head and this stuff prints like a dream at 205 degrees on my rig. It never tangles, the filament diameter is very consistent, the colour is consistent too, and layer bonding is perfect, even for structural parts with high infill. I've got white, grey, black, orange and green and they all behave exactly the same - reliable, predictable and great bed adhesion at 50 degrees with a PVA wash on the bed (to the point where I have to chisel off parts with large bed contact area). There are so many different PLA makers at the moment, and I'd put Prima pretty close to the top of the pile for quality and consistency, even compared of more expensive filament.

Not impressed with this stuff at all. I've used several different brands of PLA, including cheap generics. I only use it for prototyping, nothing critical, it's easy and fast and the cheaper it is the better. This stuff is the absolute cheapest I could find so I thought I'd give it a try. I loaded it up, dialed in my standard PLA settings, started a print and.. zero bed adhesion. I spent the next hour trying various settings with no luck, it simply would not stick. I loaded a reel of PLA from a different brand just to ensure my printer wasn't at fault, it printed perfectly. I emailed the manufacturer, and to their credit I got a very fast response, this is what they told me: "Both the SELECT and VALUE line are so called "modified PLA" which for some people can get persived as harder to print - it's not. It's just a matter of finding the right setting on the printer you are using for the moment." So.. It turns out that the issue was actually my perception of how hard this product was to print. I decided to attempt printing again, this time with a radically different perception of how this stuff could perform. I perceived it as being a top level PLA, perfectly uniform in shape and density, accepting of standard PLA temperatures, capable of printing the finest of details with a gorgeous smooth and glossy finish. I loaded it up, full of positivity, confident in its qualities and.. it didn't print :( I spent another few hours with it, trying various settings, and eventually I did get it to stick. The trick was to take my carefully calibrated extruder and force it into the print bed, with the first layer ending up basically as a smear. This worked for a while but then stopped working, leading me to believe that this stuff has serious dimensional issues. I gave up. This stuff is not good, I'm sure it varies heavily from batch to batch and maybe I just got unlucky but I can't recommend it. Spend a few pounds more and get something else.

Used to be good, have used Prima for a couple of years, no problem. This has a different appearance, smells different and prints like cottage cheese, I expect that the filament is not totally dry, will be my last purchase of this brand, especially as it used to be £16 a roll and a much better product back then. Anyone looking for an alternate, have a look at the BQ range of PLA, that is currently around the £13 mark on prime for a 1KG roll if you can live with the poor design of the spool, forget about using that on its edge as one side smaller than the other.

This company's filaments are excellent value for money and have (so far) never disappointed me. I have purchased a wide variety of different colour PLA filaments and each one performs as the last. The only thing I've noticed is that the "sweet spot" on the extruder temperature varies slightly on different colours - so don't assume that one temperature will be good for all. I have found that a quick test print (of your favourite calibration test) will be enough for you to "dial in" the best temperature for each particular filament. Once the temperature is established it seems to work flawlessly, and produces very good prints.
