Bulk Export: Aesthetic and Functional Considerations
Silk finish PLA creates smooth lustrous surfaces mimicking polished ceramic. Understanding silk production, trade-offs, and verification is essential. Our silk PLA uses modified polymer promoting controlled crystallization, creating pearlescent sheen intrinsic to filament.
Chemistry of Silk PLA
Blending PLA with modified polymers alters crystallization, promoting uniform structures. Reduces tensile 10-20% vs standard. Elongation may increase.
Silk vs Matte vs Glossy
| Attribute | Silk | Matte | Glossy |
|---|---|---|---|
| Visual | Pearlescent | Non-reflective | Hard gloss |
| Tensile | 40-50 MPa | 45-55 MPa | 50-60 MPa |
Applications for Silk
Consumer designers: enclosures, decorative panels. Jewelry: finished pieces. Education: displays. Metallic shades popular. Premium margins.
Quality Verification
Visual under D65. Gloss at 60 degrees (15-25 units). Microscopic imaging. Diameter at 40 points. Evaluate under own lighting.
Print Settings
200-225 C, bed 50-60 C. Layer 0.12-0.20 mm. Speed 40-60 mm/s. Cooling 80-100%. Insufficient cooling = patchy.
