Title:
CONTROL METHOD FOR THREE-DIMENSIONAL PRINTING DEVICE AND THREE-DIMENSIONAL PRINTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/142955
Kind Code:
A1
Abstract:
Provided are a control method for a three-dimensional printing device and a three-dimensional printing device, the three-dimensional printing device comprising a support (1), a printing head (2) and a driving assembly (3). The support (1) comprises a first fixing piece (11), a connecting piece (12) and a second fixing piece (13) which are sequentially connected; the first fixing piece (11) is connected to the printing head (2); the connecting piece (12) comprises a first side surface and a second side surface, the first side surface and second side surface being two opposite surfaces; the first side surface is a plane, and the second side surface is recessed towards the first side surface to form a recessed part; a strain gauge (121) is provided on the first side surface; and the second fixing piece (13) is connected to the driving assembly (3). The method comprises: controlling a printing head (2) to move in a first direction on the basis of N coordinate points of a first plane; according to a voltage value outputted by the strain gauge (121) and the distance moved by the printing head (2) in the first direction, determining three-dimensional coordinate information of N contact points; and on the basis of the three-dimensional coordinate information of the N contact points, determining a reference printing surface corresponding to a printing platform (4). The problems in the existing technology of relatively low leveling precision and relatively complex operations are solved.
