導入
This manual provides essential information for the proper use and maintenance of SUNLU PLA 3D Printer Filament. PLA (Polylactic Acid) is a widely used thermoplastic material known for its ease of use, reliability, and versatility in FDM (Fused Deposition Modeling) 3D printing. This filament is designed to offer excellent layer adhesion, minimal warping, and consistent diameter for high-quality prints.
SUNLU PLA filament is suitable for a broad range of FDM 3D printers due to its precise dimensional accuracy of +/- 0.02mm and standard 1.75mm diameter. The filament is neatly wound to prevent tangles and jams, ensuring a smoother and more efficient printing experience.
製品の特徴
- 高い互換性: Designed for almost all 1.75mm FDM 3D printers.
- 寸法精度: +/- 0.02mm for consistent extrusion and print quality.
- Neatly Wound Spool: Reduces tangles and jams, ensuring smooth feeding.
- Excellent Layer Adhesion: Promotes strong and durable printed objects.
- Minimal Warping & Stringing: Contributes to cleaner and more precise prints.
- 環境に優しい素材: Made from ultra-pure PLA raw materials derived from corn extract, non-toxic.

Setup and Spool Assembly
The SUNLU PLA filament may come with a reusable spool design, allowing you to replace the filament core while retaining the outer spool. This section details how to assemble the refill filament onto the reusable spool.
Assembling the Reusable Spool
- Separate the Spool Sides: Gently pull apart the two halves of the reusable spool.
- Prepare New Refill: Unpack the new refill filament. Do NOT remove the plastic straps that hold the filament neatly wound until instructed.
- Load Refill Filament: Align the refill filament with the central hub of one spool half. Ensure the small triangular mark on the filament core aligns with the corresponding mark on the spool half.
- Combine Spool Halves: Place the second spool half over the filament, aligning its triangular mark with the filament and the first spool half. Press firmly to combine.
- Lock the Spool: Rotate one side of the spool towards the "lock" mark until it clicks securely into place.
- Remove Plastic Straps: Once the spool is securely assembled, carefully remove the plastic straps from the filament. Ensure the filament is pressed close to the spool to prevent any gaps.

運用ガイドライン
For optimal printing results with SUNLU PLA filament, adhere to the following recommended settings and practices:
| 設定 | 推奨範囲 |
|---|---|
| ノズル温度 | 200〜230℃ |
| ベッド温度 | 50〜65℃ |
| 印刷速度 | 50~100mm/秒 |
Always perform a small test print or calibration cube when using new filament or adjusting settings to fine-tune for your specific 3D printer model.

メンテナンスと保管
Proper maintenance and storage of your PLA filament are crucial for preserving its quality and ensuring consistent print results. PLA can absorb moisture from the air, which can lead to printing issues such as bubbling, stringing, and reduced print strength.
保管に関する推奨事項:
- 乾燥を保つ: Store filament in a cool, dry place, away from direct sunlight and humidity.
- 密閉容器: After opening, store the filament in an airtight container or resealable bag with desiccant packets (silica gel) to absorb moisture.
- オリジナルのパッケージ: If possible, keep the filament in its original vacuum-sealed packaging until ready for use.
- 絡まりを防ぐ: To prevent tangling, always insert the filament end into the side holes of the spool after each use.

一般的な問題のトラブルシューティング
While SUNLU PLA filament is designed for reliability, occasional printing issues may arise. Here are some common problems and their potential solutions:
| 問題 | 考えられる原因 | 解決策 |
|---|---|---|
| Clogging/Jams | Moisture absorption, incorrect temperature, tangled filament. | Dry filament (use a filament dryer), adjust nozzle temperature, ensure filament is neatly wound and not tangled. |
| Bubbles/Steam during printing | Moisture in filament. | Dry filament thoroughly before use. |
| 層接着不良 | Low nozzle temperature, incorrect bed temperature, dirty print surface. | Increase nozzle/bed temperature within recommended range, clean print bed, apply adhesive if necessary. |
| ワーピング | ベッドの接着力が不十分、隙間風、ベッド温度が不適切。 | Ensure proper bed adhesion, use an enclosure, optimize bed temperature. |
| ひも | High nozzle temperature, incorrect retraction settings, wet filament. | Lower nozzle temperature, adjust retraction distance/speed, dry filament. |
| Filament breaking/brittle | Moisture absorption, old filament. | Dry filament, ensure proper storage. |
For persistent issues, consult your 3D printer's specific manual or contact SUNLU customer support.
