Stone Gray PLA Prime

Polylactic Acid is a biodegradable, eco-friendly plastic, known for its ease of use and low warpage quality. PLA Prime is Coex's 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 their 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.

Recommended Print Settings

Coex 3D recommends the following print settings when printing with their PLA Prime. 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 filaments. Using 100% virgin resin causes Coex's PLA 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, 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.
Drying: PLA Prime 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. They recommend drying their PLA at 55 °C for at least 3 hours if it has been exposed to excess humidity.
