Description
Filament is the one consumable where the cheap roll and the good roll look identical on the spool and behave nothing alike on the machine. The Three Kilo is ANYCUBIC PLA+ in a three kilogram spool, which is the size that matters for anyone printing more than one project a month: fewer changes, fewer partial spools in the cupboard, and one continuous batch of colour that will not shift shade halfway through a large print.
The specification that decides whether a roll prints reliably is diameter tolerance, and this one is controlled to plus or minus 0.02 millimetres. At 1.75 millimetres nominal, that tolerance is what keeps extrusion volume consistent from the first metre to the last, because a filament that wanders by 0.1 millimetre changes the flow rate enough to show as banding on a vertical wall. The winding is deliberately tidy and cross-laid rather than loosely spooled, which is what stops the tangle that ruins a fourteen hour print at hour twelve.
PLA+ is not PLA with a marketing suffix. The modified formulation raises toughness and impact resistance, so parts survive being dropped and clips survive being flexed, while keeping the printing behaviour people like about PLA: no enclosure, no heated chamber, low warp, and a finish that takes paint and glue cleanly. It holds dimensional stability well enough that large flat parts stay flat, and the layer adhesion is consistent rather than the brittle snap that standard PLA shows on thin walls.
The material is imported, non-toxic and vacuum sealed with desiccant, which matters more at three kilograms than at one: a spool that absorbs moisture over months prints with popping and stringing, and a spool this size takes long enough to use that packaging is part of the specification. Compatibility is broad enough to be uninteresting, which is the point, and shelf life is stated at two years sealed.
Buy filament by the batch, not by the panic.
Key Features
- Three kilogram spool Roughly three times the print time of a one kilo roll, so one batch carries a whole project in a single consistent colour.
- Plus or minus 0.02mm tolerance Controlled diameter keeps extrusion volume stable, which is what prevents banding on tall vertical walls.
- Tidy cross-wound spool Wound to resist tangling, so a long print does not fail at hour twelve on a crossed strand.
- PLA+ toughness Higher impact resistance than standard PLA, so clips flex and dropped parts survive.
- Low warp, no enclosure Prints on an open machine, which keeps the barrier to entry where it should be.
- Vacuum sealed with desiccant Moisture protection matters at this spool size, because the roll is open for months.
- Consistent colour batch One spool, one dye lot, so a multi-part assembly does not shift shade between parts.
- Wide printer compatibility Works on the large majority of FDM printers and 3D printing pens at standard PLA temperatures.

Where It Belongs
It suits the workshop that prints brackets, jigs, enclosures and replacement knobs, where a failed print costs an afternoon rather than a photo opportunity. It suits the hobbyist who has graduated from one kilo rolls and is tired of running out mid-assembly, and it suits anyone producing the same part repeatedly who wants one dye lot across the batch. The three colours are the practical ones: white for painting and for light diffusion, grey for showing surface detail, black for functional parts that should not look like prototypes.
Frequently Asked Questions
Q: Does a 3kg spool fit a standard printer?
A: Not all of them. A three kilogram spool is physically larger than a one kilo roll, so check the spool holder diameter and clearance on your machine. Many printers need an external side-mounted holder or a bearing spool holder for this size.
Q: What temperatures should I print at?
A: Start at 205 degrees Celsius nozzle and 60 degrees bed, then adjust in five degree steps. PLA+ typically wants slightly more heat than standard PLA for the best layer adhesion.
Q: Will it string?
A: Less than wet filament, and more than dry filament. If you see fine hair between travel moves, dry the spool at 45 degrees for four hours before blaming the settings, since moisture is the usual cause.
Q: Is PLA+ food safe?
A: No 3D printed part is food safe in a practical sense, because layer lines harbour bacteria and brass nozzles contain lead. Use it for models, jigs and functional parts, not for cups or cutlery.
Q: Can I paint it?
A: Yes. Grey and white take primer and acrylic well. Sanding with 400 then 800 grit before priming gives a finish close to injection moulded, and PLA+ sands without the fuzz that standard PLA shows.
Q: What is the shelf life actually?
A: Two years sealed. Once opened, moisture absorption is the limiting factor, so store it in a sealed bag with desiccant, or in a dry box if the room is humid.
Q: Does the ±0.02mm tolerance apply across the whole spool?
A: It is a controlled specification across the production run rather than a spot check at the start of the spool. That is what matters for flow consistency, since a diameter that drifts mid-print changes extrusion volume.
