DIY Filament Extruder Kit v2

DIY Filament Extruder Kit v2

$ 350.00

v2 vertically mounted

v2 hung on a door

Like the v1 version, the v2 version could be operated horizontally or vertically. It's recommended that it be operated vertically and use the motor speed controller and the temperature controller to control the diameter of the extruded filament.

v2 has the following improvements:

1. More Powerful Motor.

    DC 12V, 11.36 RPM (No Load) / 9 RPM (Load), torque.

2. Motor Speed Control w. Forward / Reverse Switch.

3. Stronger Extruder Frame (keep the frame from twisting).

The kit comes with a laser cut plywood box that houses the PID, SSR, Motor Speed Controller and the switches and connectors.

How to buy

I am offering this extruder as a kit that contains the materials needed to make this extruder except for the user supplied items mentioned below.

- Shipping: Free shipping to most major countries worldwide. Please contact me to see if free shipping is applicable to your location.

- Tax and tariffs: To be paid by the buyer.

- Item Location: Taipei, Taiwan.

User supply items:

The following items are not included in the kit and they need to be provided by the user.

- A 12V, 30A DC Power Supply;

- A 3D Printer with 20cm x 20cm x 20cm printing envelop (for printing the Hopper and the Hopper Base), the STL files will be provided;

- 18 AWG stranded copper wires (red, black, yellow, blue) - the length of the wire is depending upon how you arrange the extruder, power supply, and the control unit. (for my case, 4-meter for each color is more than enough);

- Power sockets and plugs;

- Basic hand tools (wire cutter, screw drivers, pliers, etc.);

- Solder, Soldering Iron, Solder Paste.


As the characteristics of material vary significantly, care must be taken to work out the optimal extrusion conditions (extrusion temperature, extrusion speed, pressure inside hopper, etc.) to achieve the desire result.


This machine must be operated in a well ventilated area and be attended by an operator constantly to minimize hazards (fire, toxic fumes, etc.).
