Filament welder v2

Never waste short pieces of filament or partial spools ever again. The filament welder v2 lets you join filament with ease in seconds with no hardware, ptfe tubes, or any other non 3d printed object — giving you waste reduction at your fingertips.

How it works:

When your filament gets heated up, it starts to soften and when you clamp it in the merging part, the soft filament gets pushed together and melts together, leaving you with a strong bond.

Assembly:

The hinges are assembled simply by threading 1.75mm filament through the hinge holes and cutting the excess off using scissors or flush cutters. 

How to use it:

Step 1. Grab your two ends of filament and cut them at 45 degree angles ( Also make sure the filament is straight )

Step 2. push the two strands of filament into the holes on the holder

Step 3. Heat up the filament to temperature using a heating element (I'm using a lighter)

Step 4. Push the filament holder down, press on down the lid and push filament ends in ( you can layer the melted ends over each other for a better bond but will result in slightly more trimming )

Step 5. Open it up and trim excess material off using a flush cutter ( Optional: sand it down for smoother result)

End result (no sanding)

So why use a filament welder?

• Join filaments together so you can create multicolor prints without ams
• Save small pieces of filament
• Prevent print failures for swapping filament manually

Tips and warnings

Only compatible with 1.75mm filament

use high temp filaments to print to make lifespan longer
