Introduction

Reprap Wilson is a descendant of the Prusa i3 style reprap. It also has elements similar to the Lulzbot Taz.

The main goal of Wilson was to replace the frame with one built from standard Aluminum extrusions (2020). Additionally, the design has a parametric build area, meaning it is relatively easy to scale the X, Y, and Z axis within reason. I've also made an effort to reduce the number of unique parts used as much as possible, and incorporated some other design ideas that I have tried on the Prusa i3 previously (monolithic Y ends, easy adjustment of the Z limit switch, integrated endstop holders, among others).

The standard BOM is for a 210mm x 210mm x 200mm build area.

Build Variants

There are two variants of the reprap Wilson design, tentatively called the R and T Series, or simply RS and TS.

Wilson RS

The RS is the original model, with Round (R) threaded rods for the Y axis. Advantages of the RS: Less extrusions to buy, if you already have or have access to M10 threaded rod. For the same print volume, the RS is shorter (Z axis), which results in shorter extrusions and Z axis rods.

Wilson TS

The TS uses T-slot extrusions for the Y axis (as well as the frame, like the RS). Advantages of the TS: A single type of framing element is used (2020 extrusion), which simplifies the BOM. The Y axis is more rigid to the frame, which makes front-to-back stress on the frame less likely to cause any wobble. Because the print bed is higher, there is room beneath the bed for a 12V PSU and electronics board.
