280% Elongation at Break: Yingpu’s New Copolyamide Material Redefines the Flexibility Limits of 3D Printing

Core Performance: Remarkably Enhanced Toughness

Available in black and white, Precimid1190Pro offers a substantial leap in material toughness:

· Ultra-high elongation at break (280%)
Compared with the 8%–17% elongation at break of standard PA12 materials (Precimid1172Pro), Precimid1190Pro achieves a dramatic increase to 280%—an improvement of over 2,150%. This remarkable resilience enables the material to withstand significant deformation before fracturing, effectively resisting impact and repeated bending, while greatly reducing the risk of brittle failure.

· High-precision molding with excellent reusability
Despite its enhanced toughness, the material fully meets the SLS process requirements for high-precision molding, capturing intricate design details with clarity to ensure both functional integrity and aesthetic quality. Furthermore, with a low new-powder ratio of just 15%, Precimid1190Pro offers outstanding powder recyclability. This not only lowers production costs but also improves efficiency and minimizes material waste.

Application Focus: Rehabilitation and Comfortable Wearables

Thanks to its exceptional flexibility and durability, Precimid1190Pro is the ideal choice for high-performance material solutions in the fields of medical rehabilitation and customized wearable products:

· Customized rehabilitation orthoses
Applicable for wrist, palm, and ankle supports, Precimid1190Pro’s high toughness and durability ensure stable and reliable support throughout the patient’s recovery process, with minimal risk of deformation. After chemical vapor smoothing, the orthoses achieve a smooth, refined surface that significantly improves breathability, reduces heat buildup during wear, and facilitates cleaning and disinfection—enhancing long-term comfort and treatment compliance.

In addition to precise customization for hand and wrist anatomy, 3D-printed copolyamide orthoses can undergo dyeing and other post-processing treatments to meet patients’ aesthetic preferences.

· Eyeglass frames
For 3D-printed eyewear, Precimid1190Pro offers substantial toughness improvements, reducing the likelihood of breakage from accidental bending or drops, while enabling the creation of lighter, more stylish, and highly durable frames.

With its defining performance metric—an elongation at break of 280%—Yingpu’s Precimid1190Pro high-toughness copolyamide powder has successfully overcome the flexibility limitations of traditional 3D-printed nylon materials, pushing the performance boundaries for flexible applications. This breakthrough delivers more reliable, durable, and design-liberating solutions for industries ranging from medical rehabilitation to personalized consumer goods and demanding functional components.
