REUSABLE MASTERSPOOL & VACUUM PACKAGE

Based on the concept of environmental protection, we have enhanced the pla pro filament with a new materspool, resulting in cost saving and reusability. After the filament runs out, you can buy SUNLU refills to refill it. FDM filament with vacuum package can protect the filament from moisture.

RAPID PLA+2.0 & HIGH COMPATIBILITY

Our high speed filament achieves the print speed of close to 300MM/S while ensuring excellent printing. Suitable for most FDM 3D printers using 1.75mm filament. Widely used in machinery, education, industry, automobiles, decoration, COSPLAY.

NEATLY WOUND PLA+2.0 FILAMENT & +/- 0.02MM TOLERANCE

Full mechanical winding and manual inspection can reduces tangles and breakage issues, less warping, no bubble. Technology control guarantee a filament diameter of 1.75mm with tolerance of +/-0.02mm, minimizing clogging and stringing. Strict tolerances make smoother printing and printer well.

CUSTOMER SERVICEOLERANCE

Recommend printing at a nozzle temperature of 205-215°C, a bed temperature of 50-65°C, and a printing speed of 50-300mm/s. If you have any question about 3d filament, please don't hesitate to contact us. You can add the 2kg pla+ to shopping cart first to help quick finding.

SUNLU 3D Printing Troubleshooting Guide

Issue 1: Filament Surface Defects (Notches/Damage)

Root Cause: Physical damage during production or transportation.
Solution:

1. Immediately stop printing. Check the remaining filament on the spool for defects.

2. Contact SUNLU Support: Provide clear photos of the damaged section for replacement.

Issue 2: Uneven Model Edges

Root Cause: Inconsistent extrusion due to filament diameter variation or moisture.
Solution:

1. Measure Filament Diameter:

Extract 1-meter filament and use calipers.

Gently clamp the filament at the center of the calipers (avoid excessive force).

Tolerance range: 1.75mm ±0.02mm.

Dry Filament: Use a filament dryer at 45-50°C for 4-6 hours if moisture bubbles are observed.

Issue 3: Stringing/Oozing

Root Cause: Insufficient retraction, high nozzle temperature, or damp filament.
Solution:

1.Retraction Calibration:

Start with default settings: Retraction distance 5mm, speed 40mm/s.

Adjust within 20-100mm/s range through iterative testing.

2.Temperature Optimization: Reduce nozzle temperature by 5-10°C if stringing persists.

Issue 4: Filament Tangling

Root Cause: Improper storage or reloading of partially used spools.
Solution:

Locate the tangled section and carefully unwind it.

Preventive Measure: Always secure filament ends using the SUNLU filament clip or thread through the spool hole after use.

Issue 5: Poor Bed Adhesion

Root Cause: Incorrect nozzle height, low bed temperature, or rapid cooling.
Solution:

Nozzle Height Calibration: Adjust to A4 paper thickness between nozzle and bed.

Temperature Adjustment:

Increase bed temperature (e.g., PLA: 60°C, PETG: 70°C).

Apply SUNLU bed adhesive or enable "Raft" in slicing software.

Issue 6: Brittle Filament

Root Cause: Over-drying (>48hrs at high temps) or factory defects.
Solution:

For over-dried filament: Store in sealed bags with desiccant.

Contact SUNLU Support if brittleness occurs immediately after unsealing.

Issue 7: Color Discrepancy

Root Cause: Lighting variations or minor batch differences.
Solution:

Compare under 6500K white LED light (industry standard).

Note: Natural color variations within ±5% are normal.
