Too much retooling and the cost would probably double. My Experience with this product: I'm on my second one. First one worked a couple of times and the metal heating bar just fell out of the jaws. The second one I've used probably a hundred times. (1) I Turn on the Filament connector letting it heat up. (2) I flush cut each end of the Filaments to be connected. (3) I open the Jaws and put one side half way in. (4) I push the other Filament in half way. (5) I start my first stopwatch timer for 4 minutes. (6) When the timer goes off I turn Filament connector off and grab both pieces of Filament close to the Filament connector and push them towards each other for 1/4" or so. (6) Start the send timer for 10 minutes. (7) When 10 minute timer goes off I open the Filament connector and use a razor blade to lightly cut along the filament in the Jaw. Then I use a tiny screwdriver and working from each end "lightly" start to get under the filament in the jaw and pry up. Doing so on both ends. (8) trim most of excess with razor blade and sand with a Nail file emery board. Works like a champ... **Q: I mostly use pla as i don't have an area to control the temperature for abs. how does this work with pla?** A: The melting temperature of PLA materials from different manufacturers may be different. You need to control the heating time to achieve this. Of course, even if it is heated for a long time, its temperature will be constant at about 220 ℃, which can also meet the connection of all kinds of filaments. **Q: will this ever be available again?** A: Sure, on Amazon. **Q: Does this still break pretty easily or is it a good investment?** A: I have had mine for quite a while and it is still going strong. Nothing has broken and I have used it many times. I believe it is a great investment. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 値段だけの価値はあると思います *by A***ー on January 1, 2025* 中途半端に残ってしまったフィラメントを溶接する為に四苦八苦してほぼ失敗していました。この溶接機を使っ見たら簡単に失敗せずに溶接ができました。中途半端なフィラメントが無駄にならずにすみます。 ### ⭐⭐⭐⭐⭐ フィラメント接続が上手くいきました。 *by 山***一 on October 11, 2024* 慣れが必要ですが、2〜3回試すと上手く接続出来るようになります。特に、冷却時間の5分はフィラメントをうまく保持しないと切れてしまいます。少量残ったフィラメントを使うのに多用しそうです。 ### ⭐⭐⭐⭐ 綺麗に接続できる。 *by し***ん on November 13, 2023* 中途半端に余ったフィラメントの継ぎ足しに使用。まだ、PLAしか試していないが、綺麗に接続でき取れてしまう事が無いので非常に便利。接続時にバリもでないので、接続してそのまま使用できる。難点があるといえば、フィラメントの挟み込みが強いので開きながらフィラメント位置を調整するのが大変なくらい。もう少しクランプが適切だとフィラメントの位置調整も楽になると思う。他のレビューでは壊れるとか割れるとかあったが、おそらく通電時間が長すぎると壊れやすいんだと思う。①フィラメント先端を90°にそれぞれカット。②クランプを開いてフィラメント先端をクランプの中心にあるヒーター部中心にセットしてクランプを閉じる。③反対側からフィラメントを挿入して先にクランプしたフィラメントに当たるまで差し込む。 この時、先にクランプしたフィラメントが移動してしまったらやり直し。④各フィラメントの指定された時間だけボタンを押して通電。 PLAだと2分くらい。⑤通電OFF後にそのまま5分程度放置。 但し、熱でフィラメントが柔らかくなるので、通電後はクランプから出ているフィラメントを押さえておいた方がいい。(そのままだとぐにゃっと曲がることがある。)⑥放置して冷めたらクランプより取外し。上記で綺麗にくっつくので、フィラメントが中途半端に残っている人には持っていて損は無いと思う。このフィラメントコネクターの注意点ではないが、巻径の大きなフィラメントに巻径の小さな余ったフィラメントを繋げる際は、繋げて巻径の大きな方に巻き取ったらすぐにフィラメントドライヤーに掛けた方がいい。フィラメントドライヤーに掛けずに防湿庫に入れておくと、特に時間の経った巻径の小さなフィラメントだと時間が経つとプチプチ切れて使い物ならなくなる。 ## Frequently Bought Together - VIT SPORT 1.75mm Filament Connector | Easy Operate Filament Welder Filament Splicer for 3D Printer | Filament Fuser Filament Joiner for PLA/ABS/PC/PETG/TPU Filaments - ELEGOO PLA Filament 1.75mm Black 2KG, 3D Printer Filament Dimensional Accuracy +/- 0.02mm, 2 Pack 1kg Cardboard Spool(2.2lbs) 3D Printing Filament Fits for Most FDM 3D Printers - OVERTURE PLA Filament 1.75mm PLA 3D Printer Filament, 1kg Cardboard Spool (2.2lbs), Dimensional Accuracy +/- 0.02mm, Fit Most FDM Printer (Black 1-Pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/743403422-1-75mm-filament-connector-easy-operation-filament-welding-machine-splicer](https://www.desertcart.sn/products/743403422-1-75mm-filament-connector-easy-operation-filament-welding-machine-splicer) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-05-31*
