DYNAMIC REAL-TIME SLICE ENGINE FOR 3D PRINTING

摘要

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.

1. A method for 3D printing without the necessity to pre-process a computer-aided design (CAD) model before delivery to a 3D printer, the method comprising:
receiving, by a 3D printer, a CAD model for a design to be printed by the 3D printer; processing the CAD model to identify a first slice and generating instructions for printing the first slice; using the generated instructions to start printing of the CAD model; in parallel with the printing, performing dynamic real-time slicing on a remaining portion of the CAD model including:
receiving pre-processed data, model analysis information or real-time feedback during the printing of a respective slice; andidentifying a next slice for printing including adjusting one or more slicing parameters based on the received pre-processed data, model analysis information or real-time feedback, wherein adjusting includes adjusting a slicing parameter for the next slice to be printed by the 3D printer; andgenerating instructions for printing the next slice; andprinting the next slice based on the generated instructions and, in parallel, repeating the performing dynamic real-time slicing to generate a then next slice and associated instructions for printing.
