On July 22, the Institute of New Materials and Industrial Technology at Wenzhou University announced a significant research breakthrough.
**PLA-Based Rapid 3D Printing Material**
Polylactic acid (PLA) is a low-carbon, green, bio-based, and biodegradable material. Compared to ABS, PLA is odorless and offers superior dimensional stability. Its low melting point facilitates easier printing, reduces thermal safety risks, and lowers energy consumption during the printing process. Additionally, PLA boasts excellent printability, ease of use, and high tensile strength, making it the most widely used material in the industry. However, PLA traditionally suffers from notable drawbacks, such as slow crystallization rates, poor melt flow, and slow printing speeds.
Through the development of key technologies-including rapid nano-crystallization and effective control of melt flow rates-this project successfully achieved the industrialization of an ultra-high-speed PLA 3D printing material. Capable of printing speeds up to 498mm/s, the material outperforms products from renowned brands like BASF and has reached a world-leading level. The global market for PLA 3D printing consumables is projected to grow from $562 million in 2020 to $1.661 billion by 2026.
**Technical Advantages:**
• High crystallization rate (10x increase)
• High melt flow rate (3–5x increase)
• 3D printing speed: Increased from 300mm/s to 498mm/s
**Application Scenarios:**
Fields such as culture and art, education and training, and biomedicine.
