Polymaker is thrilled to announce the launch of PolyCore™ PC-7413, a cutting-edge pellet-based material made from 30% glass fiber reinforced polycarbonate (PC). This advanced material is specifically engineered for medium-temperature (80 °C - 120 °C) composite mold applications, an area that has rapidly evolved in recent years through the adoption of fused granule fabrication (FGF), also known as Large-Format Additive Manufacturing (LFAM). By leveraging FGF/LFAM, manufacturers achieve significant reductions in lead time and production costs.
“Over the past few years, producing large molds has rapidly become the most popular application of FGF/LFAM. PolyCore™ PC-7413 combines exceptional printability with cost-effectiveness to set a new benchmark in mold manufacturing.” Stated Raymond Huang, Director of Polymaker’s FGF Business.

Key Features and Industry-Leading Capabilities
PolyCore™ PC-7413 boasts numerous advantages, making it an outstanding choice for medium-temperature composite mold applications.
- Excellent Heat Resistance: With a heat deflection temperature (HDT) of 136 °C at 1.82 MPa, PolyCore™ PC-7413 is ideal for autoclave curing processes up to 120 °C.
- Exceptional Printability: The glass fiber reinforcement minimizes warping during printing, and its finely tuned rheological behavior ensures smooth extrusion and excellent layer adhesion.
- Cost Effectiveness: PolyCore™ PC-7413 offers a cost-effective alternative to traditional carbon fiber reinforced materials, making it perfect for companies scaling up production without compromising on performance.
The material's performance was validated through a real-world case in which an aerospace-grade mold was successfully produced and subjected to additional rigorous testing. The mold met strict requirements for dimensional tolerance (± 0.2 mm) and airtightness, confirmed by high-precision laser scanning and vacuum tests. These results demonstrate the material’s exceptional heat resistance, strength, and dimensional stability, underscoring PolyCore™ PC-7413 as an ideal choice for composite mold applications.

A Collaborative Success with Helio Additive
Beyond PolyCore™ PC-7413’s inherent material properties, we believe that the printing process, optimized by Dragon was also a critical factor in achieving the complete mold validation. By using a thermal history simulation for each voxel, Dragon’s optimization achieved a more uniform thermal distribution across the mold, reducing internal stress and enhancing layer adhesion. This process refinement contributed to the mold’s dimensional stability and airtightness, leading to a successful "First Time Right Print" with a 38% reduction in printing time.
