摘要： A method for printing a three-dimensional object in a volume of a photopolymerizable liquid by photopolymerization, the method comprising: (a) providing a digital representation of a three-dimensional object that has been sliced into a plurality of sequential two-dimensional image slices along the z-direction; (b) processing each of the two-dimensional slices of the three-dimensional object into a sequence of subsampled images, each subsampled image comprising an arrangement of pixels wherein each pixel has defined x and y dimensions; (c) sequentially exposing each of the sequence of subsampled images of a slice at a selected location along the z-direction in the volume using excitation light until the volume at the selected location along the z-direction has been exposed to all of the subsampled images of the slice, and (d) sequentially repeating step (c) for a previously unexposed sequential slice of the three-dimensional object, each at different selected location along the z-direction, until the three-dimensional object is formed. A pixel can comprise a single pixel or a grouping of pixels. Preferably the pixels in a grouping of pixels are adjacent pixels. Preferably, the pixels of a subsampled image are separated from each other by a distance. Other methods are further disclosed.

摘要： Photohardenable compositions comprising a photohardenable component and a photoswitchable photoinitiator, wherein the photoswitchable photoinitiator is activatable by exposure to light having a first wavelength and light having a second wavelength to induce a crosslinking or polymerization reaction in the photohardenable component, and wherein the photohardenable composition displays non-Newtonian rheological behavior are disclosed. Methods including such photohardenable compositions for printing one or more objects are also disclosed.

摘要： A method of printing one or more three-dimensional objects comprises: providing a volume of a photopolymerizable liquid in a closed container including an entry port and an exit port, the entry port and the exit port being connected by a channel therebetween, the container including at least one printing zone comprising at least an optically transparent window to facilitate irradiating excitation light at a first wavelength into a printing zone through the at least an optically transparent window, wherein the photopolymerizable liquid displays non-Newtonian rheological behavior such that the object formed in the photopolymerizable liquid within the printing zone remains at a fixed position or is minimally displaced in the unpolymerized photopolymerizable liquid during formation, directing the excitation light through the at least an optically transparent window into the printing zone to selectively photopolymerize the photopolymerizable liquid in the printing zone without support structures to form a printed object, wherein the printed object remains at a fixed position or is minimally displaced in the unpolymerized photopolymerizable liquid during formation, and applying pressure to the contents of the closed container and/or pumping additional photopolymerizable liquid into the closed container through the entry port to at least transport the printed object out of the printing zone toward the exit port, thereby discharging at least a portion of contents of the closed container out of the closed container through the exit port. Systems for printing one or more three-dimensional objects are also disclosed.
