Three-dimensional printing apparatus
First Claim
1. A three-dimensional printing apparatus, configured to form a three-dimensional object layer by layer with a modeling material and comprising:
- a printing assembly, comprising a feeding tube, a driving wheel set and a nozzle, wherein the driving wheel set is disposed between the feeding tube and the nozzle to drive the modeling material transferred to the nozzle from the feeding tube and exit from the printing assembly via the nozzle so as to form the three-dimensional object layer by layer; and
a cleaning unit, having a brush, wherein the brush leans against and contact with the driving wheel set so as to clean out the residual modeling material while the driving wheel set rotates relatively to the cleaning unit.

Abstract
A 3-D printing apparatus is configured to make a modeling material form a 3-D object layer by layer. The 3-D printing apparatus includes a printing assembly and a cleaning unit. The printing assembly includes a feeding tube, a nozzle and a driving wheel set disposed between the feeding tube and the nozzle to drive the modeling material transferred to the nozzle from the feeding tube and then exiting from the printing assembly via the nozzle so as to form a 3-D object layer by layer. The cleaning unit has a brush, in which the brush leans against on the driving wheel set to clean out the residual modeling material while the driving wheel set rotates relatively to the cleaning unit.
