bambulab A1とAMS liteを使用している環境で、プリンターで印刷した除湿ケースから乗り換えました。 <プリントして使用する除湿ケースの難点> ・スプールとケースのマージンが少なく、スプールの出し入れが難しい ・その為出し入れの際に再生紙製スプールが壊れそうになる事も多かった ・ケースと送り出し機構のアライメント調整が難しく、フィラメントにかかる負荷が高くなって印刷に不具合が出ることがあった ・ケースに窓を設置していたものの、真上から見る形なのでフィラメントの残量が分かりにくい ・除湿用のシリカゲルの交換タイミングがわかりにくい&忘れがち 本製品とAMS miniを印刷して組み合わせることで、上記の不満点が全て解消し、とても満足度高いです。 <フィラメント送り出し用の穴> フィラメント送り出し用の穴は蓋と横壁の2パターンありますが、 蓋が開けやすいので自分は横壁から出す方が使いやすく感じました。 PTFEチューブに多少余裕を持たせてやれば、送り出しの負荷が高くて不具合を起こすこともありません。 <自動除湿機能> また、自動除湿機能が想像以上に便利です。 湿度が30%を上回ると自動的に除湿し、常に30%以下に保ってくれます。 シリカゲルの状態を気にする必要も、入れ替える必要もなくなり、快適です。 (湿度何%を上回ったら除湿するかは任意で設定可能) <フィラメントの確認> 蓋を開ければフィラメントの残量確認や、絡まりの解消もしやすいです。 <動作音> 動作音もプリンターと比較すると静かなので、自分は気になりませんでした。 値段は高いですが、それだけの価値はあり、プリント環境が非常に快適になったので満足度は高かったです。

Solid drier. I print a lot of filament and a single spool dryer just wasn't going to cut it for my needs. This 4 spool dryer works well and does exactly what i need. I really like that it has outlets for using as a dry and print box. I print directly from this dryer on my bed slingers and the quality had really improved printing from a dry roll. Keeping your filament dry is keep to reducing stringing and having it stay within the box helps reduce tangles. The dryer has a solid amount of preset choices for temperatures for a variety of filaments, but you can fine tune it for any specialty filament. My only wish would be that it was split and could dry 2 types of filament at the same time. However I just throw them in as a little extra temperature doesn't appear to affect my PLA when drying with PETG.

The SUNLU S4 Filament Dryer Box is absolutely flawless. It arrived exactly as described and works perfectly right out of the box. The ability to dry four spools at once is a huge time saver, and the results are consistent—no more moisture issues or printing problems. The build quality feels solid, the controls are intuitive, and the temperature holds steady throughout the cycle. I’ve run multiple types of filament through it (PLA, PETG) and every spool came out dry and ready to print with noticeably improved performance. This product does exactly what it promises, and it does it reliably. For anyone serious about 3D printing, this is a must‑have accessory.

The Sunlu filament dryer works well. All of their products are great quality at a decent price. The customer service is great. It's easy to operate just remember to rotate your spools. It comes with a few tubes ready to connect to your printer.
