Filament Fuser Electronics & Hardware Kit

.

This listing is for the Assembled Hardware & Electronics parts needed to build the “Filament Fuser Block” as seen on 3DPrinting.com here. The finished device can be used to fuse together two ends of FDM 3D printing filament, any size and any material!

This kit contains all the hardware and electronics already assembled exactly as shown in the first image. This kit does NOT include the 3D printed parts, but don’t worry, the associated 3D Printable files are available for FREE on Thingiverse.com here.

PLEASE BE AWARE: This product is designed & intended to be controlled by your existing 3d printer controller. This is super easy to do on a reprap printer, but may be difficult for some commercial devices. If you need a stand-alone controller, my recommended solution is to get the cheap complete reprap ramps kit and just use it for this purpose. (After you get it setup you won’t even need to connect it to your computer!) Control kit available here and a power supply for it here.

How to fuse filament:

The secret to getting a good bond is a combination of good tool and the right technique. First warm up your Block by plugging it into your 3D printer controller. Just borrow the same set of pins that your extruder uses.

Then take about 1” of filament in each hand and follow this quick procedure.

  1. Push the filament into the side of the block for a couple seconds until it starts to mushroom out. (so you know it’s hot)
  2. Push the separate pieces together using the top groove as a guide.
  3. Slide the fused filament from the guide so that you scrape off the mushroomed material, leaving a smooth side.
  4. Side the fused filament through the side groove to remove the rest of the mushroom.
  5. Hold the bond in front of the fan until it cools.
  6. If necessary use the various edges of the block to scrape off any excess material or re-smooth the bond.

Let your slicing software to tell you how much filament the print needs and divide that length into segments to choose where certain colors will show up.
