  • Patent number: 10539949
    Abstract: A three-dimensional printing apparatus and a method for calibrating printing inaccuracy thereof are provided. A printing head of the three-dimensional printing apparatus is adapted for moving along a straight printing path on a datum plane and simultaneously feeding out forming material, so as to generate a layer object on a supporting surface of a platform. If a path distance of the straight printing path is greater than a threshold, a plurality of linear compensation relationships respectively corresponding to a plurality of first zones of the supporting surface are used for calculating a first compensation value of a starting point and a second compensation value of an ending point. If the path distance of the straight printing path is not greater than the threshold, a common compensation values is decided based on at least one of second zones and which is corresponding to the starting point and the ending point.

  • Patent number: 10493745
    Abstract: The invention provides a method for height difference measurement between the print heads and a 3D printer using the method. The 3D printer includes a printing module, a contact sensor, a movement sensor and a controller. The controller makes a 3D print head and the contact sensor contact to each other vertically for generating a contact signal, and obtains a first height value according to a vertical movement distance between the printing module and the contact sensor. The controller makes a color head and the contact sensor contact to each other vertically for generating the contact signal, and obtains a second height value according to a vertical movement distance between the printing module and the contact sensor. The controller obtains a height difference between the 3D print head and the color head according to the first height value and the second height value.
