High-Quality Silver PLA+Silk 3D Printing Filament
PLA+Silk gives a glossy shine to anything you print with it. It looks great, is extremely easy to print with, and has generally good mechanical properties. It's perfect for showpieces and decorative models.
Coex 3D PLA+Silk is made with Virgin NatureWorks USA Ingeo resin, a high-quality colorant, and our secretive additive. All of Coex's filament is made in our production facility located in Wisconsin, USA. Coex 3D uses industrial-grade extruders and laser measuring quality control to ensure quality, consistency, and a 1.75±0.03mm diameter specification with every spool. We provide filament that gives excellent-looking and strong prints.
Coex 3D recommends the following print settings when printing with our PLA. Settings will vary depending on your specific printing setup.
- Hotend Temperature: 215 °C - 235 °C
-
Important! This temperature range may seem hotter than you're used to for other PLA+Silk filaments. Using 100% virgin resin causes our PLA+Silk to require slightly higher printing temperatures.
- Heated Bed Temperature: 40 °C - 60 °C
- Note: A heated bed is not a strict requirement when printing PLA+Silk, but using one is recommended.
- Recommended Build Surfaces/Adhesives
- Glass Build Surface
- PEI Build Surface
- Magigoo
- Painter's Tape
- Glue Stick
- Cooling Fan: Recommended. Up to 100% fan speed is advisable when printing PLA+Silk.
- Drying: PLA+Silk filament is hygroscopic and will absorb moisture from the air if not stored in a dry environment. If this happens, you may experience under-extrusion/inconsistent extrusion or excess stringing. You may also hear a "popping" sound coming from the hotend during printing. We recommend drying our PLA at 55 °C for at least 3 hours if it has been exposed to excess humidity.
Technical Printing Guide - COEX PLA
1. Material Notes
- Keep filament dry - store properly and dry before use
- PLA is less hygroscopic than other materials, but proper storage helps maintain quality
- If needed, dry at 55°C for 3 hours or more
- Check for any visible damage before use
2. Basic Parameters
PLA (Polylactic Acid) is a biodegradable polymer known for its ease of printing, good surface quality, and dimensional accuracy. Perfect for decorative parts, prototypes, and general printing needs where mechanical properties are not critical.

| 0.6mm | 0.6-1.0mm | 45mm/s | 0.2mm |
| 0.8mm | 0.8-1.2mm | 40mm/s | 0.2mm |
| 1.0mm | 1.0-1.5mm | 35mm/s | 0.2mm |
5. Temperature Settings
Bed Temperature: 60°C
- Wash the bed often for good adhesion - Use dish soap and rinse thoroughly to remove oils
- Use bed adhesion products if necessary (gluestick, WELD3D)
- Use brim for tall or large prints
- Keep ambient temperature stable
Extruder Temperature: 215-235°C
6. Cooling Settings
Cooling Configuration:
- First Layer: 0% (fan off)
- General Printing: 100% base fan speed
- Bridges and Overhangs: 100% fan speed
- Layers < 15 seconds: 100% fan speed
Critical Considerations:
- PLA requires maximum cooling for best results
- Full fan speed helps with bridging and overhangs
- The first layer needs no cooling for good adhesion
- Small parts need maximum cooling
7. Troubleshooting Guide
| Problem | Solution |
| Poor Layer Adhesion |
1. Increase temperature by 5-10°C 2. Reduce cooling fan speed for first few layers 3. Clean build surface with IPA
|
| Warping |
1. Increase bed temperature to 60°C 2. Add brim (5-10mm) 3. Ensure no drafts in printing area |
| Stringing |
1. Lower temperature by 5°C 2. Increase retraction speed to 45mm/s 3. Adjust retraction distance |
| Under-extrusion |
1. Increase temperature by 5-10°C 2. Clean nozzle or try cold pull 3. Check filament quality |
| Poor Overhangs |
1. Ensure 100% cooling 2. Reduce temperature by 5°C 3. Reduce print speed by 50% |
PLEASE NOTE: These printing parameters are initial recommendations based on our experience. They may need adjustment depending on your specific 3D printer, environmental conditions, and the geometry of the part you are printing. Use these settings as a starting point and fine-tune them according to your specific needs.
