Patent number: 11260595Abstract: A light-curing 3D printer includes a main-tank, a printing platform, a lighting unit, a liquid material contained in the main-tank, an isolation fluid contained in the main-tank and floating upon the liquid material, a membrane arranged upon the isolation fluid, and an auxiliary mechanism. The 3D printer controls the lighting unit to emit light toward the liquid material according to slicing data of one cured-layer of a 3D model for forming a 3D object. The 3D printer then controls the printing platform to lower and activates the auxiliary mechanism to keep varying the status of the isolation fluid. Next, the 3D printer determines whether the 3D model is completed, and controls the lighting unit to emit light according to slicing data of a next cured-layer if the 3D model is not yet completed.Type: GrantFiled: December 30, 2019Date of Patent: March 1, 2022Assignees: XYZPRINTING, INC., KINPO ELECTRONICS, INC.Inventors: Wei-Chun Jau, Tsung-Hua Kuo, Hung-Peng Kang, Yi-Tang Kao

Patent number: 11260596Abstract: A hybrid laser printing (HLP) technology that utilizes ultrafast laser in sequential additive-subtractive modes to create 3D hydrogel constructs. The approach involves the synergistic use of additive crosslinking and subtractive ablation processes that are conventionally mutually exclusive. HLP can be operated at virtually any penetration depth and allow fabrication of multi-layer hydrogel constructs at micrometer resolution. HLP was used to print ready-to-use functional chips using commonly used hydrogels for potential cellular communication and migration applications. HLP was also found to be compatible with in situ printing of cell-laden hydrogel constructs. HLP makes shaping of soft hydrogels into 3D multi scale functional devices possible.Type: GrantFiled: July 11, 2019Date of Patent: March 1, 2022Assignee: SYRACUSE UNIVERSITYInventors: Pranav Soman, Puskal Kunwar, Zheng Xiong
