Introduction
- Prusa 3D printer Hephestos is a free project 'designed and developed by the Department of Innovation and Robotics bq'. Hephestos is based on the Prusa i3 and adds several improvements learned from other printers as PowerCode users of the RepRap community, modifications to these parts and designs own department.
- This project has sought to offer a robust printer design that solves many of the shortcomings of earlier designs such as the subjection of the limit switches and cable routing. We have placed particular emphasis on providing good documentation to facilitate and more comfortable to the user installation and commissioning of the printer.
- The complete kit can be purchased from July 7, 2014 on the website http://store.bqreaders.com/es/diy/ 499 Euros with VAT in EU (European Union) Free shipping expenses.
