Prusa i3/fr

Introduction

Le modèle Prusa i3 (3 ème itération) est la nouvelle et actuelle imprimante 3D designée par le noyau de développeurs Prusajr. La i3 inclus les leçons apprises des deux précédents designs Prusa, comme tous les autres designs de RepRaps.

Principales Améliorations

The following is a list of the main improvements made upon the Prusa Mendel Iteration 2

   enhanced frame rigidity (prevents x backlash)
   easy assembly
   parametric files for multiple sizes/bearings or bushings

Development

The development of the Prusa Mendel is hosted on github: https://github.com/josefprusa/Prusa3. [modifier] History [modifier] Printed Parts

The STL files to make the printer can be found at Clone_wars:_Prusa_iteración_3.

To compile yourselve use the files from Github 2 (box style files) 3 (Singel sheet style) Copy configuration.scad.dist to configuration.scad and fill custom settings section there

RP every .scad in this directory (except complete-printer) once. Aim for 0.3mm layers and 2.2 extrusion width (width over thickness), for 0.66mm stroke width. Printer is tested at this setting.

Using doc/complete-printer.scad as a visual clue and doc/manual.txt as a guide, build the printer. [modifier] Frame type

There are two major Prusa i3 Frame Styles, the Single Sheet Frame, and the Box Style Frame. The Single Sheet Frame is designed to be manufactured through the use of a Laser cutter, WaterJet, or CNC Mill / Router Table. There are two current development tracks within the Single Sheet Frame, an Aluminium frame style, and a gusseted Wood frame style. Both are designed to support 6mm or thicker framing material. The Box Style Frame is designed to be easily manufactured at home with basic woodworking tools. The Y-axis for both frame styles is similar to that of the older Prusa Mendel Iteration 2.

Single Sheet Frame

This is a frame created from a single sheet of metal, typically Aluminum, but can also be made from various Materials with a thickness greater than 6mm / 0.25 inch Prusa i3 with a single metal sheet style frame. Prusa i3 with a single metal sheet style frame.

pro:

- Looks professional (subjective)

con:

- requires specialised tools (e.g. Water flow jet cutter)

- Less rigid connection between XZ-frame and Y-frame part
