Introduction
This document contains the Manufacturing,
Assembly and Operational instructions for 3dp’s
Wind Turbine.
This fully functional wind turbine has been
specifically design to be manufactured, assembled
and operated at home with its unique 3d printable
design. The wind turbine is optimized to produce a
power output of 5 Watt (12volt ~4amps) at 5m/s
wind speeds, perfect for battery charging
applications.
The wind turbine has been designed with a
unique Passive Variable Pitch (PVP) design. The PVP
maintains an optimum power output through control
of the turbines rotational speed. Whilst optimizing
power output the PVP also protects the Turbine from
dangerous over speed conditions, limiting its
maximum revolutions per minute in wind speeds
greater than 5m/s.
The main components of the turbine have been
designed for Additive Layer Manufacturing (ALM)
methods using PLA plastic. 95% of the ALM
components require no post processing as these parts
do not require ‘print supports’ reducing material
usage whilst improving the overall finish of the part.

MKII Design Improvements
The MkII has three design improvements, the first is an
all important tail fin to allow the turbine to turn into the
wind and extract the maximum wind energy in
changeable conditions, the second is a stiffer tower
structure with bigger bearings and increased diameter
locating pin to support the increased loads from the tail
whilst allowing for the third improvement which is the
inclusion of Split Ring Electronics. The Split Ring
Electronics allows the turbine to spin around the tower
axis without any limitations it brings the power
electronics into the tower where there is more space and
its easier to access.
The MkII requires the following new parts:
