  • All Metal V6 1.75mm
    The best option, it includes all the advantages of the latest design, more compact and a better temperature control.
  • All Metal V5 3mm:
    The most economical option, high quality and multilateral.
  • All Metal V5 1.75mm
    The most economical option, high quality and multilateral.


  • 0.2 – 0.8
    We offer a wide range to choose the most suitable for your application, about 0.4 are the most popular choices.
    Smaller diameters provide higher resolution and larger diameters print faster and stronger parts.

LCD with SD reader:

  • 2004 LCD Smart Controller
    Control your printer in real time, without a PC. Highly recommended option.
  • 12864 LCD Full Graphic Smart Controller
    Control your printer in real time, without a PC, also the most comfortable way. Highly recommended option.


  • Ramps 1.4.
    Without a doubt the most popular electronics for your 3d printer.
  • Ramps 1.4 SB
    All the attributes of the Ramps 1.4, with additional protections, and manufactured in Spain. And also with an appearance more attractive

Power Supply:

  • 12V 30A Ultra compact (With switch y printed part)
    The best solution to power your printer, compact, stable, and with power to spare. We also include switch, protector printed on PLA and power connector.
  • No
    If you want to recycle a PC Power Supply, this is your option.


  • 4x Clips for Heated Bed
    Used to adjust the glass to the Heated bed
  • Thermal Insulation for Heated Bed
    Increases the rate of heating of the bed, reduces energy consumption, and protects the electronics
    (We recommend to isolate with kapton the part in contact with the Heated Bed)
  • Filament ABS - 1Kg – Colour depending on stock – Diameter selected
  • Filament PLA - 1Kg – Colour depending on stock - Diameter selected
  • Tempered Borosilicate Glass
    An ideal base on which to perform your impressions, smooth and strong.
  • Kapton Tape 15mmx33m 
    Insulating tape resistant to high temperatures, highly recommended, as it serves both to insulate the connections (for example the Heated Bed) and to hold cables.

LCD with SD card reader, it allows the printing without needing to connect it to the PC. In addition, from the LCD you can adjust multiple of options: 

Hotend, it is the element that melts the filament: 

Nozzle, it the extreme of the extruder, and defines the thickness of the filament being extruded: 

We offer a wide range to choose from for your application, nozzles around 0.4mm are the most popular choices. Smaller diameters provide higher resolution and larger diameters print faster and stronger parts

Ramps (RepRap Arduino Mega Pololu Shield), it is the electronic component that controls the printer power: 

Printing Surface, it heats up the surface so the filament can adhere to it easily: 

You can add some extras for your kit. We recommend the borosilicate tempered glass, as it is the perfect 3D printing surface, it is very flat, resistant and easy to clean

How to Change the Nozzle

Fátima 14/09/2016 1
Our 3D printer, as every machine, needs a maintenance. One of the most basic ones is the change of the nozzle of our hotend. We may need to change it for several reasons, as for example, needing a smaller or bigger diameter (as bigger diameters are better for resistent parts with few details and fast printings and small diameters are better for sma...
