Summary

The Filament Fuser Block enables you to securely fuse two ends of 3D printing filament together in roughly 10 seconds. With this tool you can recycle leftover filament, extend the length of your filament spools for long prints, and add color changes to your prints!

The printed parts enable you to safely hold the heated block under a hinged guard, and clamp everything to the side of a table. It works on 2.85mm and 1.75mm filament in any printing material. The Fuser Block is controlled by plugging the (3) two-pinned connectors into your existing 3D printer controller, so you can precisely control the temperature!

These 3D printing models are shared here for free, but to complete the assembly you'll need the associated hardware kit from the EngineerDog Store here: https://engineerdog.com/store/filament-fuser/

Complete assembly and use instructions available on 3D Printing.com here: http://3dprinting.com/how-to/fuse-filament-home/... See image attached for recommended print settings

Update: Now included is a printable jaw cover that fits on standard 6" slip joint pliers. Using grooved pliers to squeeze a freshly made warm joint with as it cools helps compact it and further strengthens the bond.

UPDATE 1: This device is intended to be controlled by your existing 3d printer controller. This is super easy for a reprap printer, but difficult for some commercial devices. My recommended solution for a stand alone controller is to get the cheap complete reprap ramps kit and just use it for this purpose. (After you get it setup you wont even need to connect it to your computer!)

UPDATE 2: New part "Clamp Face V2" is intended to replace the original clamp face. The new one doesnt require a nut to do the job!

ATTENTION ALL:
I am not affiliated with jasonmrc and his stand alone temperature controller product and as of this writing (9-19-16) I do NOT recommend the use of his stand alone controller with my product.

The reason being that his current version does not provide a means for powering the cooling fan which is an essential part of this tool. (Operating the device without the fan is hazardous, as its primary purpose is to cool the shaft to prevent your plastic frame from melting down. Cooling off the fused joint is a secondary purpose.) Additionally, it lacks the proper pin connections for making direct connections to my product without having to splice wires.
If these conditions change I will update this comment.

hi

designed the controller for the filament fuser .. anyone interested ?

temperature controller is now available ready built and tested .. more info on my tindie page !

Hello,

At what speed is this tingie printed best?
I have a zonestart p802m

I am not familiar with that printer, but in general the slower you go the better quality you get. These parts are big and chunky and there are only a couple of fitted surfaces so you could get away with the slop introduced by printing fast if you wanted to.

Is it possible to print the parts in PLA or do I need to print them in ABS for higher temperature resistance?

The white one shown in the main pic is PLA and it has worked just fine! The trick is keeping the little fan on 100% of the time to keep the rod cool.

How about a custom arduino temp controller for this project ? if i see interest i might design it ..

Ok im on it .. shall design one ! what features would you consider i should include ..

temperature control -
set preset for pla and abs ?

a go button and a shutdown button ..
an lcd ? which shows all the info ?

A LCD and presets for different filaments would be great. But manual temperature setting should also be possible.

For temperature control, existing PID temperature control librarys for Arduino, like the one at http://playground.arduino.cc/Code/PIDLibrary and autotune libraries to help you tune it like http://playground.arduino.cc/Code/PIDAutotuneLibrary could be used.

A MOSFET to switch the heater and the fan on/off could be added together with the LCD and some buttons and connectors to a Arduino Proto Shield - or use one together with the Adafruit LCD shield (https://www.adafruit.com/products/772) which has already the LCD and buttons all ready to use.

All these features are implemented in my controller !

Where do I find information about your controller?
