Polymaker Panchroma Marble PLA Filament 1.75mm 1kg

Stone, without the weight. Panchroma Marble is a PLA loaded with mineral particles that break up the surface as it prints, so a finished piece reads as cut stone rather than plastic — most convincing on large flat faces and gentle curves.

It's aimed squarely at things you display: statues, busts, architectural models, planters, vases, chess pieces. No enclosure, no special profile, just a slightly slower print and one hardware requirement worth knowing about before you start.

At a glance

Worth knowing

Polymaker state a 0.4mm nozzle as a requirement, not a preference. The mineral filler that makes the stone effect will bridge and jam a finer nozzle. Plenty of people run this at 0.6mm or 0.8mm quite deliberately — a wider extrusion shows the speckle off better and prints a large decorative piece faster.

It's the stiffest PLA in the Panchroma range and among the strongest in tension — 3427 MPa modulus and 52 MPa tensile, well above the Matte. What it gives up is toughness: at 3.3 kJ/m² notched impact it's roughly a third of Matte's, so it chips and cracks rather than bending. Treat it as an ornamental material and it's excellent; drop a functional part in it and you'll be disappointed.

Run cooling on full and keep the speed down — 200 mm/s is the ceiling rather than a target, and the texture reads better at moderate speeds with thinner layers.

Storage

Polymaker specify drying at 55°C for 6 hours, and only if a spool has actually taken on moisture. Sealed with fresh desiccant between prints it rarely needs it.

As filament takes on moisture you'll hear popping or hissing at the nozzle, then see stringing and rough surfaces, and eventually the strand goes brittle enough to snap in the tube. That's almost always moisture, not technique — dry it and it usually comes back.
