Pumpkin Orange PLA Prime
Polylactic Acid (PLA) is made with natural, renewable materials, such as starch, corn or sugar cane. Because these materials make up PLA, it is better for the environment than other materials, and it can be recycled. PLA Prime is made from a higher grade resin than our already high grade PLA resin. PLA Prime is a great material for prototyping and aesthetic models. Due to the ease of printing, PLA Prime filament is a popular choice, not only for beginners, but even pros. PLA Prime is by far the most used filament by printers, beating out ABS, PETG, TPE/TPE, and Nylon for the top spot.
Coex's PLA Prime products are made with Virgin NatureWorks USA Ingeo resin and high quality colorant only, no fillers. All of Coex's filament is made in our production facility, located in Wisconsin, USA and uses industrial grade extruders and laser measuring quality control. We provide filament that gives excellent looking & strong prints.
Technical Printing Guide - COEX PLA Prime
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.

4. Retraction Settings
| Nozzle | Distance | Speed | Z-Hop |
| 0.4mm | 0.5-0.8mm | 45mm/s | 0.2mm |
| 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.
