What is PLA 3D870?

NatureWorks designed this PLA specifically for industrial 3D printing. It offers impact resistance superior to ABS, and once annealed, competes in thermal performance.

PLA 3D870 combines the ease of PLA printing with ABS-level mechanical performance. Compared to standard PLA, 870 offers:

• Improved mechanical strength
• Greater impact resistance
• Better heat resistance
• High printing resolution
• Strong adhesion and minimal warping
• Low odor

How to print PLA 3D870?

Use your slicer software with the following settings. Lower speed and layer height give finer detail, but increase print time. Dark pigments like black may require slightly higher temperatures.

• Nozzle temperature: 205 – 220 ºC
• Bed temperature: 40 – 60 ºC
• Fan: ON (100%)
• Layer height: ≥ 0.1 mm
• Print speed: 30 – 60 mm/s
• Material flow: 100%

POST-PROCESSING

How to anneal PLA 3D870?

1. Preheat oven to 110 – 120 ºC
2. Place the printed part inside. Use supports if needed for larger pieces
3. Annealing time: 20 minutes for 3.18 mm wall thickness
4. Cool down at room temperature without handling
5. Measure before and after to calculate any shrinkage

Annealing alters the molecular structure (crystallization), improving thermal and impact resistance. Be aware of dimensional changes.

MAINTENANCE

Maintain your 3D printer's extruder regularly to extend the machine’s lifespan. Use cleaning filament and brass brush as needed.
