Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a method for 3D printing without preprocessing a CAD model before delivery to a 3D printer. The CAD model for a design to be printed is received by a 3D printer. Instructions are generated for printing the first slice. While the instructions are used to start printing the CAD model, dynamic real-time slicing is performed on a remaining portion of the CAD model. Preprocessed data, model analysis information or real-time feedback is received during the printing of a respective slice. A next slice is identified, and slicing parameters are adjusted, including adjusting a slicing parameter for the next slice. Instructions for printing the next slice are generated. The next slice is printed based on the generated instructions. Dynamic real-time slicing is repeated to generate a then next slice and associated printing instructions.

A method generates a three dimensional representation of a garment and comprises: obtaining a three dimensional human body model comprising an outer surface representative of an outermost surface of a human body; obtaining a three dimensional representation of a garment; and simulating a three dimensional physical interaction of the three dimensional body model with a three dimensional representation of the garment. Simulating the three-dimensional physical interaction comprises: deforming both the three-dimensional body model and the three dimensional representation of the garment; and displaying the deformed three-dimensional human body model and the deformed three-dimensional representation of the garment.

Described herein are three-dimensional (3D) printer systems and methods, which may provide for “continuous pull” 3D printing. An illustrative 3D printer includes: a resin container, a base plate, a light source arranged below the resin container and operable to cure resin in the resin container; and a control system operable to: (a) receive model data specifying a 3D structure; (b) determine 2D images corresponding to layers of the 3D object; and (c) generate control signals to operate the light source and the base plate to sequentially form the layers of the 3D object onto the base plate, wherein the base plate moves a formed portion of the 3D object upward after formation of each layer, and wherein at least a surface of a formed portion of the 3D object remains in contact with the resin in the resin container throughout the formation of the layers of the 3D object.

Techniques are disclosed for converting a stereolithographic model into an STL data file that defines logically related components and subcomponents of an object. A user can categorize elements of an object to form logically related components and subcomponents of the object. Each element is represented by a triangle. All triangles representing each of these components and subcomponents are then reordered and listed sequentially within the STL. Each list is delimited at the beginning and end by two hidden triangles, one or both of which store unique identification values that are associated with the respective individual components. Additionally, a reference table can be added to the STL. The reference table includes instructions, operations or other information that is specifically associated with each component and subcomponent using the unique identification values. These instructions and operations enable users to have better control over 3D print quality than is possible using existing techniques.

A computer program product for proactive heating-based crack preventing in three-dimensional printing is provided. The computer program product includes a computer readable storage medium having program instructions embodied therewith. The program instructions are readable and executable by a processing circuit to cause the processing circuit to read a three-dimensional model to be printed, determine if the read three-dimensional model has open-ended or closed-ended layers, for each closed-ended layer, calculate start and end heating times and amount of heat requirement for materials of the closed-end layers and control a heating of the closed-ended layers in accordance with the calculation during a laying down of each of the closed-ended layers.
