Improvements in or relating to the manufacture of three-dimensional objects

摘要

A prototype including both a main part and support part is fabricated on a platform. A first charging device charges a first charged area and a first material dispensed by a first dispensing device is attracted to the first charged area. A second charging device charges a second charged area and a second material dispensed by the second dispensing device is attracted to the second charged area. The first and second charging devices as well as the first and second dispensing devices are moveable to build a layer of the main part and support part.
