Transition “Mystery” Color PLA Prime
A great opportunity to pay less for great PLA Prime filament! Our transition color PLA Prime filament is the same high quality PLA Prime filament that our customers trust but in "mystery colors." These varying colors are the result of our changeovers from one of our standard color to another during production of our filament and cannot be reproduced. Let us choose a color for you and you will receive 1kg of filament for the 500g price!
Purchase 1kg of PLA Prime filament at the 500g price. This Transition Color filament in a "mystery color" at the 500g price! Colors vary. (This item is not returnable due to color).
Note: These are not a rainbow filament.  The color change in each spool will vary and be very gradual.
*This product is limited to availability as we make changeovers. If you cannot add it to your cart, we are sorry, but we are out of stock.

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. 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
3. 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.

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.
