Introduction
The main idea of this printer is to create a new design of a 3D printer with a cubic cartesian scheme which includes as many as possible parts from plastic. I.e. it supports the RepRap concept to create some kind of easy reproducible 3d printer to make it more achievable for a wide engineer society. One of the main concepts is that all plastic parts designed to be printed by one hotend 3d printer without using supports.

Main improvements
The following is a list of the main improvements made upon the Prusa Mendel Iteration 2
- Enhanced frame rigidity (prevents x-axis backlash)
- Easy assembly
- Parametric files for multiple sizes/bearings or bushings
Development
The development of the GLKLN is hosted on github: https://github.com/Konstg16/GLKLN-V1.0.
History
Variants
Main article: Prusa i3 Variants
The release of the Prusa i3 under the GPL license and numerous other factors (its low cost, minimal BOM, simple assembly and calibration procedures, more than adequate documentation, etc) have encouraged the further development of a growing number of Prusa i3 "variants" worldwide, with different parts, different materials and different assembly processes, but which altogether adhere to the general looks, component assembly, dimensions and functionality of the original Prusa i3.
See the page Prusa_i3_Variants for an attempt to list the Prusa i3 Open Source variants along with their differences / improvements and "genetic lineage". Also check out the Category: Prusa i3 Derivate page which lists using the wiki tagging feature.
Printed Parts
OpenSCAD files for the printed parts are available on the Github repository.
To compile the parts and render STL files, copy configuration.scad.dist
[3] to configuration.scad
, and customize by editing values.
Precompiled STL files to make the printer can be found at the Clone Wars page for the i3, and here zipped up: File:Clonewars.zip.[1]
Frame type
Most major Prusa i3 Frame Styles fall into two categories: 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. Both the EiNSTeiN variant and the i3 Rework designs use single sheet aluminum frames, as do most kits. The Box Style Frame, on the other hand, 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 flat metal sheet, typically Aluminium, but can also be made from other material with a thickness usually between 3mm (0.125 inch) and 6mm (0.25 inch).
Pro:
- Looks professional (subjective).
Con:
- Requires specialized tools (e.g. abrasive water jet cutter, laser cutter, CNC router) or contracting out.
- Less rigid connection between XZ-frame and Y-frame part.
Box Style Frame
This frame is created from 8 small sheets of wood.
Pro:
- Can be created with standard DIY tools.
- More rigid connection between XZ–frame and Y–frame part part.
Con:
- Looks less professional (subjective)
Electronics
Stepper Motors
The Prusa i3 uses, including the extruder, 5 NEMA17 stepper motors. Two of these motors, the Z axis motors, are connected to the same stepper driver of the electronics. If using Wade's Extruder, its stepper motor needs a minimum holding torque of 40Ncm (0.4Nm). More information can be found on the Stepper Motor page.
Controller Electronics
About any RepRap controller works for the Prusa i3. Required features: 4 stepper drivers, 1 thermistor input and 1 heater output for the extruder and optionally another thermistor/heater pair for the heated bed. Choosing the best one for your printer is mostly a matter of taste. For comparisons, see List of electronics, Comparison of Electronics and Alternative Electronics.
Extruder
On November 12th, 2012 Josef Prusa (@josefprusa) tweeted a picture of his metal frame i3 with a custom dual extruder mounted.
Previous posts on Prusa's twitter feed reveal that Sound (Slic3r's Developer) inspired Prusa to attach a dual extruder.
In may 2015 was published the &makers single direct drive extruder named &struder, was designed to use on Wood multitool and now is adapted to use on prusa i3.
Heated Bed
The Prusa i3 includes a Heated Bed which allows for the use of materials such as ABS and nylon which can experience significant warping if printing on a cold platform.
- MK3 heating bed, aluminum plate thickness of 3 mm, uniform heating, fast, back has good heat preservation, high temperature can be heated to 120 degrees

Notes
- ↑ Please note that the zipped files are not compatible with holes for the Z axis brackets in the Prusa3ALU-*.dxf drawings, at least the ones in the old/ folder in github. Also, the models for Y-axis brackets are for M8 rods. Compiling your own and investigating the Prusa github packages is highly recommended!
