Translucent Blood Red PLA Prime
Polylactic Acid is a biodegradable, eco-friendly plastic, known for its ease of use and low warpage quality. PLA Prime is our high performance PLA 3D printing filament. It is made from Natureworks Ingeo 3D850 and shows improved heat resistance, more toughness, good adhesion and less warping or curling than traditional PLA. PLA was always the go-to basic filament and is still recommended when you start your journey with 3D printing, without needing to change any of your profiles you can up your game by printing with Coex 3D PLA Prime - available in most of our standard PLA colors.
This high performance material will be perfect for that special print or prototype that you've been wanting to make but weren't sure if PLA was the best material for the job. Please realize though that all grades of PLA will still have limitations. If you truly need high strength and high heat resistance you may want to explore other materials for your project or part.
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.

| 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.
Customer Reviews
This makes a great diffuser for LEDs!
Heard about this filament on Darkmoon discord and decided to get a couple of rolls. I opted for the translucent blood and it definitely exceeded expectations. A little pricier than others so it won’t be the goto, but every now and again I’ll pick up a spool or two. Was perfected for a background on the numbers in a clock I made for my buddy who’s a mustang fan.
Beautiful, deep and unique color. The translucency gives an interesting effect where thinner details and areas allow more light to pass through, changing the hue and saturation of the color. The prints look amazing because of the added depth. It looks great on both functional and aesthetic objects. For large objects you can get very interesting effects using a small number of walls and a beautiful infill pattern - for example honeycomb. The X1C prints this filament like butter using the standard profile.
Tried the regular PLA version as well - and the color is stable between versions. Prime version can be stronger if you use annealing.
The support from Coex team is simply superb, just top notch. All questions I had were resolved instantly and to my complete satisfaction. Definitely became a regular customer here. A big plus for me is that all the production and the COEX team is here in the USA.
Thanks so much for your kind words! I'm so pleased that we were able to meet or exceed your expectations and we look forward to working with you for a long time to come!
Printed perfectly on my K1. PLA Prime has great mechanical properties that fulfill multiple functional and non-functional purposes. I have found PLA Prime to be superior to Polymaker's PLA Pro in strength even without annealing. Prints always come out clean and looking great due to the unique colors COEX offers.
COEX offers an unparalleled experience that is worth the extra couple of bucks over buying cheaper filament. When you order from COEX you are starting a partnership with a company that is invested in their work. They are very knowledgable and always willing to assist you in getting the best quality prints you can.
Love the color and printed well. Slight stringing but may be printer settings.
