It is a two-piece clamp machined from aluminium rather than printed, and the only thing it needs besides filament is a household lighter or a heat gun. \u003cspan data-token-index=\"3\" class=\"notion-enable-hover\"\u003eNo power supply, battery, app, or PTFE sleeves\u003c\/span\u003e are involved, so there is nothing to recharge and nothing to keep buying.\u003c\/p\u003e\n\u003cp\u003eLoad one filament end into each side of the channel, melt the tip of one end briefly with the flame, and push the two ends together while the plastic is still soft. The machined channel holds both ends in line and contains the softened plastic, so the weld sets close to the nominal diameter instead of as a lump on the side of the strand. Trim any flash with flush cutters and check the joint with calipers before it goes onto a spool.\u003c\/p\u003e\n\u003cp\u003eBecause the clamp is machined aluminium, the flame heats the filament rather than the tool. A jig printed in PETG or ABS softens under the same heat and its channel drifts out of line, which matters most when you sit down and join a whole box of leftovers in one session. PLA, PETG, ABS, and ASA join well; TPU deforms at the seam and fiber-filled filament does not fuse across the joint. \u003cspan data-token-index=\"5\" class=\"notion-enable-hover\"\u003eJoints must be trimmed and measured before AMS use\u003c\/span\u003e, since an oversized or oval joint is what catches inside the feeder path.\u003c!-- notionvc: b04909f7-27a5-45fa-8bf0-8763de8d5481 --\u003e\u003c\/p\u003e","brand":"Call3D","offers":[{"title":"Black","offer_id":68400988979435,"sku":"Filament-Splicer-Call3D-1","price":19.99,"currency_code":"USD","in_stock":true},{"title":"Silver","offer_id":68400989012203,"sku":"Filament-Splicer-Call3D-2","price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0779\/9039\/6139\/files\/filament-splicer-call3d-filament-welding-tool-2796011.jpg?v=1794185047","url":"https:\/\/www.call-3d.com\/products\/filament-splicer-call3d-filament-welding-tool","provider":"Call3D","version":"1.0","type":"link"}
