Abstract

The invention discloses an electrostatic spraying system of a rapid shaping device used for a nano particle material. The system comprises a spraying head (6) and a spraying nozzle (7). The system is characterized in that the spraying nozzle (7) has negative voltage. The electrostatic spraying system enables the nano particle material to be adsorbed on the surface of a workpiece under the action of a high voltage electrostatic field; and therefore, splashing and resilience are remarkably decreased, the consumption of the nano particle material is reduced greatly, and the shaping efficiency is improved.

Description

technical field [0001] The invention relates to a rapid prototyping device for nano particle materials, in particular to an electrostatic spraying system of the rapid prototyping device. Background technique [0002] Rapid prototyping technology (RP technology for short) is an advanced manufacturing technology developed in the 1990s. It is integrated on the basis of modern CAD technology, laser technology, computer numerical control technology, precision servo drive technology and new material technology. developed. Different types of rapid prototyping systems have different forming principles and system characteristics due to the different forming materials used. RP technology can be divided into the following typical molding processes: Stereolithography Apparatus (SLA), Laminated Object Manufacturing (LOM), Selected Laser Sintering (SLS), Fused Deposition Manufacturing ( FusedDeposition Modeling, FDM), three-dimensional printing manufacturing (Three Dimensional Printing,...
