Print ASA with Perfection – SUNLU's Expert Guide

Achieve optimal results with SUNLU ASA filament by following these well-tested settings and recommendations:

---

Temperature control – Stable and even extrusion

• Nozzle temperature: 250–280 °C

• Use lower end for detailed prints (50–100 mm/s) and higher for faster production (100–200 mm/s)

• Provides smooth flow and reduces the risk of drips and unwanted threads

---

Perfect first layer – Optimal adhesion

• Print bed: 90–110 °C

• Use glue stick or PEI sheet to avoid warping

• Ensure good first layer alignment for maximum stability

---

Speed ​​and Cooling – Balanced Performance

• 250–260 °C at 50–100 mm/s

• 260–280 °C at 100–200 mm/s

• Bed temperature: 80–120 °C

• Recommended cooling: Low or no fan – ASA requires slow cooling to prevent delamination

---

Closed print chamber – Prevent cracks and warping

• Use an enclosed printer with stable indoor temperature (~50°C)

• Protect against drafts and temperature fluctuations that can create cracks in the model

---

Filament Storage – Preserve Quality Between Uses

• Store ASA in airtight bags with silica gel

• Avoid moisture absorption, which can lead to bubbles and poor adhesion

---

SUNLU ASA is a high-quality choice for functional and outdoor 3D printing. With proper setup, you'll achieve prints that are strong, accurate, and weatherproof – every time.
