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. If you are interested in buying the kit or have any questions, please feel free to leave your message in the comment section below.

- Price of the kit: US$300/ea

- 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:

- A 12V, 30A DC Power Supply;

- A 3D Printer with 20cm x 20cm x 20cm printing envelop (for printing the Horizontal Hopper and the Horizontal Hopper Base for horizontal operation or the Vertical Hopper Base for vertical operation), 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, 3 meters / ea should be more than enough);

- Power sockets and plugs;

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

Note,

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.

Warning!!

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