Heating platform and 3D printing apparatus
First Claim
1. A heating platform, adapted to form a three dimensional (3D) object in a layer-by-layer manner by dispensing a thermal-plastic material, the heating platform comprising:
- a substrate, having a first surface and a second surface which are opposite to each other, wherein the first surface is used to form the 3D object;
a heating plate, attached to the second surface of the substrate to heat the substrate;
a conducting plate, attached to the heating plate to make the heating plate to be disposed between the second surface of the substrate and the conducting plate, wherein a surface area of the conducting plate is smaller than a surface area of the substrate, and an end of the conducting plate extends out of the heating plate; and
a temperature sensing element, disposed on the end of the conducting plate which extends out of the heating plate to sense a temperature of the substrate through the conducting plate.

Abstract
A heating platform including a substrate, a heating plate, a conducting plate and a temperature sensing element is provided. The substrate has a first surface for forming a three dimensional (3D) object and an opposite second surface. The heating plate is attached to the second surface of the substrate to heat the substrate. The conducting plate is attached to the heating plate, and the heating plate is coved between the substrate and the conducting plate, wherein the area of the conducting plate is smaller than the area of the substrate, and an end of the conducting plate extends to the outer of the heating plate. The temperature sensing element is disposed at the end of the conducting plate extending to the outer of the heating plate to sense the temperature of the substrate through the conducting plate. A 3D printing apparatus including the heating platform aforementioned is also provided.
