UJOYBIO --Brand Core Philosophy: quality and affordable

Ujoybio3D, part of Yuanjia Biotechnology, specializes in R&D of biodegradable materials with expertise in synthesis and modification. Backed by shareholders like Lihe Science & Technology and Bojie Shares, it has achieved core technologies for industrializing PLA raw materials and launched a thousand-ton demonstration line.

Why Choose UJOYBIO – From Source to Superior Filament

When it comes to 3D printing filaments, not all brands are created equal.
While most manufacturers simply modify pre-made PLA pellets, UJOYBIO stands apart as a true source manufacturer — one of the very few in the industry capable of chemically synthesizing 3D printing-grade PLA pellets in-house.

🔬 From Chemical Synthesis to Filament Perfection

At UJOYBIO, we control every step of the process — from chemical synthesis of PLA pellets to physical modification and filament extrusion.
This integrated approach allows us to:

Enhance filament performance at the molecular level
→ better strength, stability, and print consistency

Maintain tighter quality control
→ each batch is precisely formulated and tested for reliability

Reduce production costs
→ direct synthesis means no dependency on external suppliers

Ensure long-term material innovation
→ continuous R&D into new PLA-based materials and blends

⚙️ The Difference Compared to Typical Filament Manufacturers
Feature    UJOYBIO    Other Brands
PLA Source    Chemically synthesized in-house    Purchased pre-made pellets
Process    Chemical synthesis + physical modification    Physical modification only
Quality Control    Full-chain, from raw material to filament    Limited to extrusion stage
Material Innovation    Custom PLA formulations    Standard commercial pellets
Cost Efficiency    Lower production cost, higher value    Higher material cost, lower flexibility
💎 Result: Better Prints, Smarter Choice

By controlling the entire chain from raw material to finished filament, UJOYBIO delivers more stable printing performance, cleaner extrusion, and greater value for every spool.
That’s why professionals and creators around the world trust UJOYBIO for reliable, high-quality PLA filaments.
