The invention relates to a method for the production of blocks of material of a polymerized dental composite material as well as to the blocks of material obtainable according to the method, in which (i) a polymerisable dental composite material is transferred into a pressure-resistant casting mould (100), (ii) a pressure in the range of 10 to 500 MPa is applied to the polymerisable dental composite material in the pressure-resistant casting mould, and (iii) at least a part of the casting mould and/or the polymerisable material is heated in a defined manner to a temperature of 90 to 150 C.

Methods produce a three-dimensional dental block of material from a dental, polymerizable material. The methods include at least: transferring the polymerizable dental material into a radiolucent three-dimensional casting or press mold; irradiating the polymerizable dental material substantially from all sides with light in the UV/Ms spectral region forming polymerized outer surfaces of the dental material in the form of a solid outer shell of the dental material, wherein the shell is present in the defined three-dimensional geometry of the material whilst the inner region of the material is not polymerized or partially polymerized; heating the material with solid shell being present in defined three-dimensional geometry, to 60 C. to 150 C. for at least 90 minutes; and obtaining a dental, polymerized block of material having defined three-dimensional geometry.

Methods for manufacturing objects are provided herein. In some embodiments, a method includes receiving a digital data set representing an object, and applying energy to a curable material based on the digital data set to form the object. The object can include at least two object portions formed from the curable material using different energy application parameters. The method can further include removing residual curable material from the object. A different amount of the residual curable material can be removed from each of the at least two object portions. After the residual curable material is removed, the at least two object portions can each have different material properties.

Methods for manufacturing objects are provided herein. In some embodiments, a method includes receiving a dental appliance formed using an additive manufacturing process, the dental appliance including a plurality of appliance portions. The method can include identifying, based on sensor data, a location of a subset of the appliance portions on the dental appliance. The method can further include applying energy to a subset of the appliance portions to selectively modify one or more material properties of the subset of the appliance portions.
