摘要： A technique for fabricating a surgical splint for use in correcting a dental condition of a patient. The technique involves obtaining a three-dimensional digital model of lower and upper arch dentitions of the patient having the dental condition. Relative positions of the lower and upper arch dentitions are adjusted with respect to each other in the three-dimensional digital model using a computing device. A relative positioning structure is added to the three-dimensional digital model using the computing device. A physical model of the patient's corrected dentition is then generated from the three-dimensional digital model. The physical model includes the relative positioning structure that connects the lower and upper arch dentitions of the physical model at the adjusted relative position. The surgical splint is then formed using the physical model. A non-surgical splint is also described.

摘要： An inkjet printing method for forming a continuous three-dimensional structure is disclosed. A pre-patterned temporary structure is formed on a substrate for defining a filling groove on the substrate. An inkjet printing process is performed for filling the ink droplets into the filling groove. The ink droplets cover the filling groove and contact the surface of the temporary structure and the substrate at the same time. A self-aligned effect is formed by a composition of the gravity of the ink droplets, a surface tension between the ink droplets and the temporary structure, and a surface tension between the ink droplets and the substrate. When the ink droplets are solidified, a standalone continuous three-dimensional structure is formed by removing the temporary structure. The geometry of the continuous three-dimensional structure can be defined by the temporary structure; therefore a small track width of the solidified ink droplets can be obtained.

摘要： Since concrete materials do not cure quick enough when prototyping methods are used, so that a lower layer (2a) is already completely cured when the next layer (2b) is applied, a support material (4) is applied about the formed element (100) that is being built up in order to compensate for the lack of pressure resistance of the lower layer (2a), wherein the support material preferably has the same specific weight as the material (3) of the formed element (100). Thus, 3D-printing as well as selective curing are facilitated as build up methods.

摘要： In the case of a method and an apparatus, three-dimensional objects (16) can be produced from a solidifiable material by the sequential discharging of discontinuous drops (15). To this end, the solidifiable material is plasticized in the fluid phase and is introduced into a material store (12) having at least one discharging unit (13) which can be clocked. From there, the material is discharged in a dropwise manner by means of a discharging unit (13) in the direction of an object carrier (14) for an object (16), wherein the object carrier (14) and an outlet opening can be moved at a relative spacing in relation to one another in space in order to influence the drop shape. The creation of the drops is supported by changing the relative spacing in an alternating manner in opposite directions during the discharging of the drops from the discharging unit (13) and during the application of the drops to the three-dimensional object (16) during the production of the object.

摘要： An electrostatic three-dimensional printer in which molten material drops such as plastic and wax are given an electrostatic charge, and accelerated through a guiding magnetic field. Just as an electron is accelerated and guided in a cathode ray tube. Any molten material may be used. Parts are created by the build up of multiple layers of these droplets. When parts have overhangs a second removable material is used. In the case of plastic a lower melting point wax could be used to support the overhanging plastic then later removed from the part by melting.

摘要： An object produces from a computer data base by representing the object in the data base as a solid voxels surrounded by support voxels within a volume. The data base representation of the object as the solid voxels is converted to a data base representation of the object as a shell of solid voxels surrounding filler support voxels, and the object from said converted data base representation is constructed in a layerwise fashion. A first material is dispensed in liquid form at selected locations of a target surface, and the selected locations correspond to the shell locations of a cross-section of an object. The first material solidifies after being dispensed; a second material is applied at locations of said target surface other than the shell locations at which the first material is dispensed, to form another target surface. The dispensing and applying is repeated to form an object comprising a shell of the first material surrounding said second material, and surrounded by the second material. The portion of said second material surrounding said shell is removed, relative to the first material, to leave an object formed of a shell of the first material surrounding a portion of the second material.
