1. Moisture resistance, anti‑pilling

① Pliith ^TM PT102 particle‑accelerated aging (65°C/80% RH) for 72 hours: initial melt flow index of 3.5 g/10 min, increasing to approximately 30 g/10 min after aging—about ninefold higher than the initial value—demonstrating excellent resistance to damp‑heat aging.

②Pliith ^TM PT102 wire was left to stand naturally for 192 hours. Its initial melt index was 5 g/10 min; after aging, the melt index increased to approximately 11 g/10 min, roughly doubling compared with the initial value, indicating low moisture sensitivity.

2. Low yellowing value, resulting in a clear and transparent product.

Do your parts look dull and opaque? This is all related to the yellowness index of the PLA base material. The higher the yellowness index, the more colorant you need to add to achieve vibrant colors, resulting in parts that appear less vivid and less transparent. Pliith ^TM PT102 has a yellowness index of 5–10, domestic PLA ranges from 6 to 13, while imported PLA falls between 18 and 23, Pliith. ^TM PT102 is whiter and more translucent, making color design even simpler.

3. Moderate crystallinity, a “skeletal support” that prevents clogging.

Clogging or printing issues? It largely depends on whether there’s a crystalline region providing structural support (a scaffold)!!

The main characteristics of PLA material for 3D printing are as follows:

① Glass transition temperature (T g ) At around 60°C, the temperature in the amorphous region of PLA exceeds T. g That is, the PLA begins to soften;

②PLA melting point (T m ) At 150–180°C, the temperature in the PLA crystalline region is higher than T. m That is, the PLA begins to melt;

Pliith ^TM PT102 has a melting point of 160–165°C and moderate crystallization ability. The filaments produced exhibit a certain degree of crystallinity and good resistance to thermal deformation, preventing filament swelling and nozzle clogging caused by overheating during nozzle retraction. Moreover, its balanced crystallization properties avoid excessive shrinkage in printed parts, thereby minimizing warping and dimensional inaccuracies.
