摘要： Devices, systems, methods and computer program products are disclosed that facilitate part layer curing by an additive manufacturing device wherein each element of the part layer is exposed to light from a light source until the element receives sufficient energy to cure. In an aspect, received energy is calculated based on both the light received directly from the light source and light received from surrounding elements due to dispersion and other effects. The present disclosure enables consistent curing across a part layer, facilitate the creation of sharp outer structures, and allow fragile structures to be built alongside larger structures without a loss of quality, clarity, or resolution.

摘要： The present disclosure provides a method of making an orthodontic article. The method includes (a) providing a photopolymerizable composition; (b) selectively curing the photopolymerizable composition using actinic radiation to form an article in the shape of an orthodontic article including a number of layers of at least one photopolymerized polymer; and (c) moving the article and thereby generating a mass inertial force in the uncured photopolymerizable composition. The article has a first surface, and no more than 75% of the first surface has a slope magnitude greater than 2.5 degrees. Orthodontic articles are also provided, including an orthodontic article that is prepared according to the method. Orthodontic articles having low extractable component content are further provided. The mass inertial force tends to form a coating layer of uncured photopolymerizable composition on the article, and curing the coating layer can form a surface having low slope magnitude. The low slope magnitude may be correlated to a low haze of the surface of the article.

摘要： In a process for the lithography-based generative production of three-dimensional shaped bodies, wherein material that is solidifiable by exposure to electromagnetic radiation is present on a material support that is permeable in at least a region thereof, a building platform is positioned at a distance from the material support, material located between the building platform and the material support is heated and in the heated state is location-selectively irradiated by a first radiation source and solidified, wherein the electromagnetic radiation is introduced into the material from below through the material support that is at least partially permeable to radiation from the first radiation source, the heating of the material is performed by irradiating the material support with electromagnetic radiation of a second radiation source, wherein the material support is substantially impermeable for the radiation of the second radiation source.

摘要： A method for generating print images for additive manufacturing includes: accessing a part model; accessing a set of dimensional tolerances for the part model; and segmenting the part model into a set of model layers. The method also includes, and, for each model layer: detecting an edge in the model layer; assigning a dimensional tolerance to the edge; defining an outer exposure shell inset from the edge by an erosion distance inversely proportional to a width of the dimensional tolerance; defining an inner exposure shell inset from the outer exposure shell and scheduled for exposure separately from the outer exposure shell; defining an a outer exposure energy proportional to the width of the dimensional tolerance and assigned to the outer exposure shell; and defining an inner exposure energy greater than the outer exposure energy and assigned to the inner exposure shell.

摘要： The present disclosure provides apparatuses and methods for manufacturing three-dimensional objects. Each additive manufacturing apparatus (1000, 2000, 3000) includes: a) a reservoir (1100, 2100, 3100) for receiving hardenable material; b) a first movable light engine (1200, 2200, 3200) providing a first light radiation configuration; a second light engine (1300, 2300, 3300) providing a second light radiation configuration that is different than the first light radiation configuration; and d) a light altering structure (1400, 2400, 3400). The light altering structure is located between the reservoir and light radiated from at least one of the first movable light engine or the second light engine. The first movable light engine is configured to radiate light onto a first focal plane (2220) within the reservoir containing the hardenable material and the second light engine is configured to radiate light onto a second focal plane (2320) within the reservoir containing the hardenable material. The method includes: a) obtaining a hardenable material disposed in a reservoir; b) selectively radiating light having a first light radiation configuration from a first movable light engine; and c) selectively radiating light having a second light radiation configuration from a second light engine onto a second focal plane within the hardenable material. The apparatuses and methods can advantageously form objects having different resolutions on demand using the same apparatus, plus optionally can blend light from multiple light engines.
