METHOD FOR DETECTING CHARACTERISTIC OF FORMING MATERIAL AND THREE-DIMENSIONAL PRINTING APPARATUS
First Claim
1. A detecting method for detecting a characteristic of a forming material, the detecting method being adapted for a three-dimensional printing apparatus that comprises a tank filled with a liquid forming material, and the detecting method comprising:
- controlling the tank to swing to generate a wave motion on a liquid surface of the liquid forming material;
detecting the wave motion of the liquid forming material to obtain detection waveform information;
comparing the detection waveform information with sample waveform information to obtain a characteristic comparison result in association with the liquid forming material; and
executing a predefined operation according to the characteristic comparison result.

Abstract
A method for detecting a characteristic of a forming material and a three-dimensional printing apparatus are provided. The three-dimensional printing apparatus includes a tank filled with a liquid forming material, and the method includes the following. The tank is controlled to swing to cause a wave motion on a liquid surface of the liquid forming material. The wave motion of the liquid forming material is detected to obtain detection waveform information. The detection waveform information and sample waveform information are compared with each other to obtain a characteristic comparison result. A predefined operation is executed according to the characteristic comparison result.
