PLA Galaxy is polylactic acid in a galaxy-effect variant. A maker sells it for decorative items, toys, accessories and cosplay props, and makers describe a glossy finish that shows different colours from different angles. It is amorphous as printed, so its HDT at 0.45 MPa is 54.6–55 °C. On the H2C it prints at 200–230 °C with no heated chamber, and a maker says its silver-aluminium flakes are not abrasive to the nozzle.

Partly documented Notched Charpy impact and price rest on 1 product each, tensile modulus (XY), tensile strength (Z) and HDT at 0.45 MPa 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.

Among the materials

Against PLA-CF, PLA Galaxy is 36 % less stiff. Against PETG, PLA Galaxy is 19 % weaker across the layers and 8 % weaker flat, and its HDT at 0.45 MPa is 15 °C lower. Among the materials, PLA Galaxy has a high notched Charpy impact and a low tensile modulus (XY), HDT at 0.45 MPa and price: each is in the top or bottom quarter of the materials that publish it. The rest of its key properties sit in the middle half.

PLA Galaxy is tougher in notched Charpy than PLA-CF and PETG but costs less than PLA-CF, PLA-GF and PP and others

Thermal properties

PLA Galaxy is amorphous as printed, so it softens at its glass transition, typically 61 °C: its HDT is 54.6⁠–⁠55 °C under 0.45 MPa and 52 °C under 1.8 MPa. As published, Vicat softening is typically 56 °C and melting typically 156 °C.

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.
