Is filamentation occurring on the surface of 3D-printed parts?

This not only compromises the precision of the workpiece,

It has also severely compromised its aesthetic appeal!

 

Pliith PT102, a PLA-specific 3D printing material, has significantly enhanced the properties of PLA through optimized molecular design and synthesis processes. Hydrolytic stability 、 Reduced yellowing value and achieves a moderate degree of crystallinity, ensuring the filament is resistant to moisture challenges and simplifying color formulation, The printing process is smooth. Moreover, it boasts exceptional precision.

 

1. Moisture resistance, anti‑pilling ① Pliith™ PT102 underwent accelerated aging (65°C/80% RH) for 72 hours; its initial melt flow index was 3.5 g/10 min, while after aging it increased to approximately 30 g/10 min—about nine times the initial value. Excellent resistance to damp-heat aging. ；

② Pliith™ PT102 wire was left undisturbed for 192 hours; its initial melt index was 5 g/10 min, and after aging, the melt index increased to approximately 11 g/10 min—about twice the original value. Low moisture sensitivity 。

2 Low yellowness index, resulting in a clear and transparent product.
Do the molded parts look dull and opaque? This is all due to… The yellowness index of PLA substrates plays a critical role: the higher the substrate’s yellowness, the more colorant must be added to achieve vibrant hues, resulting in parts that appear dull and lack translucency. Pliith™ PT102 has a yellowness index of 5–10; domestically produced PLA ranges from 6–13, while imported PLA typically falls between 18 and 23. Pliith™… PT102 is whiter and more transparent, making color design even simpler. 。

3. Moderate crystallinity, with 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:

• Glass transition temperature ( T g ) in Around 60°C, the temperature in the amorphous region of PLA exceeds T. g That is The PLA is beginning to soften;
• PLA melting point (T m ) in 150–180°C; the temperature of the PLA crystalline region is higher than T. m That is The PLA begins to melt;
• Pliith™ PT102 has a melting point of 160–165°C, moderate crystallization ability, and the filaments it produces exhibit a certain degree of crystallinity, providing moderate resistance to thermal deformation. No. The filament has expanded due to overheating caused by the print head retraction. Plug Meanwhile, its moderate crystallization ability prevents excessive shrinkage in printed parts, thereby avoiding warping and dimensional inaccuracies.

4. Puris series products

Pliith Biotechnology Co., Ltd., abbreviated as “Pliith” was founded in May 2021. Building on the Chinese Academy of Sciences’ Changchun Institute of Applied Chemistry’s “next-generation polylactic acid industrialization technology,” the company centers on the commercialization of polylactic acid and has established a full‑chain industrial layout spanning R&D, production, and sales across the “biomass–lactic acid–lactide–polylactic acid” value chain.

 

The PolyLactic Acid polymerization production line of Puli Si has been… Production officially commenced in November 2023, and the product has now been launched. High-gloss, low-melt-index ( PT101), high‑gloss, high‑melt‑index (PT301), medium‑gloss, medium‑melt‑index (PT102), and low‑gloss, low‑melt‑index (PT103) A series of products.
