Three-Dimensional Printing Device and Three-Dimensional Printing Method

A three-dimensional printing method, comprising:

• moving a platform mechanism of a three-dimensional printing device such that the platform mechanism is attached to an exposure apparatus of the three-dimensional printing device;
• emitting a light by a light source of the three-dimensional printing device to cure a printing material between the platform mechanism and the exposure apparatus, so as to form a first layer of a printed object;
• moving the platform mechanism a first distance away from the exposure apparatus;
• and
• emitting the light by the light source to cure the printing material to form a second layer of the printed object, wherein the second layer has an even or uneven thickness, and a maximum thickness of the second layer is limited by the first distance.

A three-dimensional printing method, comprising:

• when a platform mechanism of a three-dimensional printing device is attached to an exposure apparatus of the three-dimensional printing device, controlling the exposure apparatus to transmit light to form an initial printed layer, wherein at least one of the platform mechanism or the exposure apparatus is a floating assembly;
• controlling the platform mechanism to move to a preset position, and controlling the exposure apparatus to transmit the light to form a current printed layer and complete a printing action of a current round, wherein the preset position is determined according to the number of the current printed layer;
• and
• executing the printing action of a next round until a preset event occurs.
