PLA Marble is polylactic acid with a marble-effect finish. A maker sells it for sculptures, artworks and architectural prints. It is amorphous as printed, so it softens at its glass transition: its HDT at 0.45 MPa is 55–56 °C. On the H2C it prints on a 60 °C bed with no heated chamber, though a maker says its heavily stone-filled product can be slightly more abrasive on brass nozzles.
Partly documented Notched Charpy impact rests on 1 product, tensile modulus (XY), tensile strength (Z), HDT at 0.45 MPa and price on 2 products each and tensile strength (XY) on 3 products. Each figure is the median of the products that publish it comparably, and beside it the middle half of them; a value on a test bar no document describes as printed, or with no stated test load, is set apart, except a heat deflection of a plastic that cannot crystallise, which its glass transition sets, unless its document points to a moulded or resin bar. Products with an added filler or additive are shown but kept out of the medians.

Among the materials
Against PLA-CF, PLA Marble is 27 % less stiff and 22 % less expensive. Against PETG, PLA Marble is 21 % more expensive and 20 % stiffer, and its HDT at 0.45 MPa is 15 °C lower. Among the materials, PLA Marble has a low HDT at 0.45 MPa and price: both are in the lowest quarter of the materials that publish them. The rest of its key properties sit in the middle half.
PLA Marble is tougher in notched Charpy than PLA-CF and PETG but costs less than PLA-CF, PLA-GF and PP and others
How does it compare with what an engineer would buy instead?
- PLA Marble: its products' median and middle half

- lowest to highest
- each material's median (top row)
- set apart: test bar not described as printed, or no stated load
- beyond the scale
Each row is a material, each column a property: the bar is the middle half of a material's products, the tick their median, the hairline their lowest to highest; the ticks above the rows are every material's median.

Thermal properties
PLA Marble is amorphous as printed, so it softens at its glass transition, typically 56 °C: its HDT is 55–56 °C under 0.45 MPa and 53 °C under 1.8 MPa. As published, Vicat softening is typically 57 °C and melting typically 160 °C.

Printing on the H2C
PLA Marble softens near 56 °C, below the H2C's 65 °C chamber
What does printing it on the H2C take, and how hot can a part get?

After printing
the suggested annealing temperature of models printed with Bambu PLA Marble is 50 to 60 °C, and the time is 6 to 12 hours.

What makers say about printing it
Printing advice
A major aspect is the use of printing nozzles with diameters of 0.4mm or more.
Spectrum PLA Stone Age, maker's product page or guide, p. 1When printing with filled/composite filaments it is recommended to clean your nozzle immediately after printing by feeding 15-20cm PLA filament through your nozzle.
FormFutura StoneFil, maker's product page or guide, p. 1This will make sure that any potential fillers are flown out of your nozzle.
FormFutura StoneFil, maker's product page or guide, p. 1It is even better to use glow in the dark PLA as the extremely hard phosphorous particles are much more likely to scrape out residual waste from your nozzle.
FormFutura StoneFil, maker's product page or guide, p. 1Experience level: Beginner
FormFutura StoneFil, maker's product page or guide, p. 1
Nozzle wear
StoneFil has a very high filling with stone powders and therefore the filament can have a slightly more abrasive effect on brass nozzles than unfilled filaments.

What it is sold for
It is widely used in sculptures, artworks, and architectural style printed works.

What makers warn about
However, it is not recommended to use a 0.2 mm nozzle for printing as clogging may occur.

Finish and accuracy
Contains 0.4 mm marble particles, giving the printed models a distinctive marble-like texture.

Makers rarely give the concentration, temperature or duration: treat them as indications, not design data. Each product's statements are on its card.
Resin reference data (for plain PLA, where no maker of these products speaks): it absorbs moisture and is dried before melt processing. Fillers, pigments and printing change this, so it does not stand for these products.
Density and price
PLA Marble's density is typically 1,240 kg/m³, the middle half 1,240–1,250 kg/m³, across 5 products. PLA Marble typically costs 31 CAD/kg, across the 2 products with a regular price in the sample; the lowest is Eryone Marble PLA at 31 CAD/kg.
| Product | Price |
|---|---|
| Bambu Lab PLA Marble | 32 CAD/kg |
| Eryone Marble PLA | 31 CAD/kg |
