Prima Filaments PV-ABS-175-0750-DG PrimaValue 3D-Print Filament, 1.75 mm, 1 kg Spool, Dark Grey

Worst ABS filament I ever purchased, and I've used many.After printing, this filament sticks like a leech-on-steroids to glass. Normally the ABS pops off when the glass cools down, but not this sucker. I can only assume the manufacturers have added something to the mix, as all other filaments I try work as expected. I'm also required to print at 250 degrees to get this filament to ooze enough to squirt out the hot end, way hotter than what I normally use for ABS.I am also suffering with clogged nozzles, whilst not unusual for 3D printing the frequency has become very regular with this garbage filament.I have had some success releasing the printed objects by placing the glass bed in my freezer, however thanks to this useless filament I've now lost 2 glass plates. The cost of ownership for this Prima Filament is very excessive.

Let me start by saying all filaments vary in material, feel and quality.I have a Da Vinci 1.0a, on some DIY printers you would probably have to tinker with the extruder/bed to get it working well. On the other Hand I am running stock firmware and have had excellent prints.My reason for purchasing a black filament was that Samsung refused to supply me replacement plastic brackets for my oven handle - so I said I will make my own :)Quality 4/5Excellent packaging, comes on a wider spool than my other filaments but same weight so not sure why they have chosen this design but it fits well so cannot complain. The initial print has a few inconsistent width as if the extruder struggles for the first second to extrude properly but after that it's perfect and really not an issue as this happens on my test line (I think other slicers do a test brim around the print before starting) so won't be an issue, probably down to my temperature but I cannot currently adjust this so just left as is. I have not noticed a big difference in the smell produced when printing. All my ABS filaments produce a slight smell but since the printer is mostly closed its not a big deal.Price 5/5At £13.49 (at the time of purchase) not the cheapest filament I have purchased but it's the second cheapest. And for the price the end product is great I would of spent double this just to source the parts I needed for my oven.Feel-Look 5/5Could not be happier with the print quality, absolutely superb! I have printed my replacement brackets at a 0.4mm later height and they look great, as its black the ridges are barely noticeable. When removing from my heated bed it sometimes leaves white marks on the bottom of the print - this does not happen on my other filaments but I have heard that black filaments can do this sometimes, I found that if you just put a spot of acetone on the marks it vanishes and gives a clean black look.Amazing buy at this price, I was a bit hesitant when I read the other reviews but after seeing a finished print and the brackets on my oven again I am ecstatic. Really good buy for me and hope others will have the same results.Extruder temp: 220cBed temp: 80c-90cPrinter: Da Vinci 1.0a - stock firmwareAttached photos of my oven handle, phone dock, keychain, failed print of laptop holder and others - ignore the stringing in the last photo that was my XYZs crappy slicer.

This was the worst purchase I have ever made on Amazon, the adherence is awful to base and other layers no matter what you print on (Tape, Print Bite, Glass) tried them all. When it does eventually stick to the base the layers don't stick so the end product is flimsy and breaks far to easily, even on 100% infill!!!! I have tried calibrating many times, changing the temperatures.... you name it I did it! Got so fed up that I scrapped the spool and returned to the good old trusty HatchBox. First print on the HatchBox was perfect, just shows how the quality differs between suppliers. If only I could find a 1.75mm black ABS from HatchBox :(

Avoid this at all cost, this is a waste of money, all my projects went failI'm a very exigent with the quality of my 3d printing and quality and smooth printing is a must for me, the only thing I could get from thiswas 2 days on calibration, cleaning the hot end from the blockage it caused, also not sticking to other players well enough to build a full project.only buy it if you are creating small pieces ie, screws, nuts and etc.

Updated - manufacturer provided a refund and paid for my broken beltI have 2 reels of this ABS - This does print ok but I have had a major problem with a black reel i bought in late 2016 so wouldn't buy again. The roll is tangled throughout and could never be left unattended. I accidently left it unattended today when using it and it resulted in the filament going tight as I wasn't there to free it. In turn this has snapped one of the stepper motor to axis belts on one of my printers. See my photos to see the state of the winding onto the roll. The blue roll I have has been fine so it must have been a bad roll/batch but has put me off this brand.

2nd spool I've bought from PrimaValue.First spool worked alright, but this one refuses to print. It'll work for a short while but then the extruded will start clicking and stop extruding.I've tried recalibrating and figuring out what's wrong, but all the other filaments I have work flawlessly while this one just fails. Every time.

Having run about 2 kilos of this filament now, after prolonged use through an E3D V6 Hot End, it can cause blockages and is very hard to clean the inside of your hot end. It leaves black scale inside the heat break, which prohibits smooth running of the filament through the hot end. This eventually transfers into the nozzle causing a blockage that can be very hard to clear. It is highly noticeable when changing filaments where even after a good hour of printing you will still end up with black streaks in your print from this filament.On the plus side, it does print well on to a PEI bed and doesn't smell as much as some ABS filaments.I would advise that unless you really want to get blockages after about half a kilo of constant use, then look elsewhere for ABS.
