NatureWorks 3D850 Hot Sale PLA Resin

Physical Properties

• Specific Gravity: Measured via ASTM D792, the specific gravity is 1.24 g/cc, reflecting the material’s density relative to water.
• Viscosity Measurement: Per ASTM D5225, the relative viscosity (RV) is 4.00 at 1.0 g/dL in chloroform at 30°C, indicating solution flow behavior.
• Melt Flow at 210 °C (410 °F): As per ASTM D1238, the melt flow rate under a 2.16 kg (4.76 lb) load ranges from 7.00–9.00 g/10 min.

Polymer Properties:

1. Base Material: Polylactic Acid (PLA)
2. Key Features & Characteristics:
   
   • High Heat Resistance: This resin is specially designed to withstand higher temperatures and is suitable for applications where parts may be exposed to high temperatures
   • Improved Impact Strength: Produces parts with significantly better durability and reduced brittleness, a common limitation of traditional PLA.
   • Optimized for Annealing: Can be annealed after printing to further increase heat resistance and crystallinity, boosting its mechanical performance.
   • Excellent Printability: Provides consistent extrusion and good layer adhesion, ensuring high-quality prints with minimal warping.

Applications:

• 3D Printing Filament Production: Ideal for creating monofilament used in FFF/FDM printers, ensuring precise detail, strong plate adhesion, and minimal warping.
• High-Temperature Prototyping: Suited for 3D printed parts requiring moderate heat resistance, such as electronic enclosures or mechanical components.
• Customized Material Formulations: Enables additive-enhanced filaments (e.g., impact modifiers, reinforcing agents) for tailored mechanical performance in diverse applications.

Processing Guidelines

NatureWorks 3D850 is designed for easy extrusion into filament and straightforward printing. It can be processed on a variety of 3D printing machines.

• Recommended Extrusion Temperature (Filament Production): 180-200 °C
• Recommended Print Temperature: 190-220 °C
• Recommended Bed Temperature: 20-60 °C (heated bed is optional but recommended)
• Drying: The resin should be dried to a moisture content of <250 ppm before processing. Recommended drying conditions are 4 hours at 40 °C.
• Annealing: For optimal heat resistance, printed parts should be annealed. Typical annealing conditions are baking the part at 110 °C for 10-20 minutes, though specific conditions may vary.
