摘要： The invention relates to a method for the stress-free polymerisation of large, three-dimensional dental material blocks that are suitable for producing dental prosthetic parts in a material removal method, said method comprising the following steps: (i) transferring the polymerisable dental material into a radiation-permeable three-dimensional casting or compression mould, so as to form a defined three-dimensional material geometry, (ii) optionally planarising at least one surface of the dental material in the three-dimensional casting or compression mould, and/or (iii) optionally applying pressure to the polymerisable material in the three-dimensional casting or compression mould, (iv) irradiating the polymerisable dental material from all sides with light in the UV/visible range, so as to form polymerised outer surfaces of the dental material in the form of a solid outer shell of the dental material, said shell being in the defined three-dimensional material geometry while the inner region of the material is not or is partially polymerised, (v) optionally removing the dental material with its dimensionally stable shell and defined three-dimensional geometry from the casting or compression mould, (vi) heating the material with the solid shell and defined three-dimensional geometry to between 60 °C and 150 °C for at least 90 minutes, and obtaining a material block that is substantially cavity-free and obtained while substantially maintaining the three-dimensional geometry that was set prior to polymerisation.

摘要： An imprint method including the steps of: an exposing step to irradiate a photo curing resin, coated on a large-area substrate, with a curing light while the light-transmitting imprint mold is pressed against the photo curing resin, an amount of the curing light applied onto the photo curing resin in a light shielding region provided with the light shielding member (5) made less than an amount of the curing light applied onto the photo curing resin in a light transmitting region of the mold so that a portion of the photo curing resin in the light shielding region is semi-cured by the use of the light shielding member (5) provided so as to reproduce the concave-convex pattern of the transparent substrate; a separating step to separate the mold from the photo curing resin after the exposing step; a moving step to move the mold so that an end of the light transmitting region of the mold is positioned on the semi-cured portion (9b) of the photo curing resin; and a repeating step to repeat the exposing step and the separating step with the mold positioned at a position after the moving step.

摘要： An inkjet-based process for programmable deposition of thin films of a user-defined profile. Drops of a pre-cursor liquid organic material are dispensed at various locations on a substrate by a multi-jet. A superstrate that has been bowed due to a backside pressure is brought down such that a first contact of the drops is made by a front side of the superstrate thereby initiating a liquid front that spreads outward merging with the drops to form a contiguous film captured between the substrate and the superstrate. A non-equilibrium transient state of the superstrate, the contiguous film and the substrate then occurs after a duration of time. The contiguous film is then cured to crosslink it into a polymer. The superstrate is then separated from the polymer thereby leaving a polymer film on the substrate. In such a manner, non-uniform films can be formed without significant material wastage in an inexpensive manner.
