Embodiment Construction

[0031] refer to figure 1 A flowchart that presents a computer-implemented method for determining the B-Rep of the outcome of the 3D printing process.

[0032] A Boundary Representation or B-Rep is a widely known format for modeling a 3D object in its boundary or envelope or skin, ie its outer surface. A B-Rep thus specifies data in a specific format that may include geometric and topological data. Geometric data is data that provides a geometric entity, which is an entity described by a 3D position. Topological data is data that provides topological entities, which are entities described in terms of references to geometric entities and / or relationships to other topological entities, such as relative positioning and adjacency relationships. In general, relationships may include "bound" relationships that relate a topological entity to other topological entities that topologically bound it. The B-Rep format is described in more detail, for example, in document EP 2 808 810 A1...

Abstract

In particular the invention relates to a computer-implemented method for determining a B-Rep of the result of a biaxial 3D printing process, said method comprising: providing (S10) a stack of planes, each pair of consecutive planes corresponding to a respective slice of the result of the 3D printing process ; for (S20) each pair of consecutive planes: providing (S210) one or more corresponding tool trajectories; determining a corresponding 2D profile corresponding to one or more tool trajectories; Respective extrudates of respective 2D profiles defined by the pair of first planes; and forming (S30) a B-Rep using the extrudates and the portion of the plane. The method improves 3D printing.

Description

technical field [0001] The present invention relates to the field of computer programs and systems, and in particular to methods for determining a boundary representation (B-Rep) of the results of a biaxial 3D printing process and / or for comparing a B-Rep to a reference (manufactured) product (e.g. a target 3D modeled object representations of parts) to compare methods, systems and procedures. Background technique [0002] Many systems and programs for design, engineering and object manufacturing are available on the market. CAD is an acronym for Computer Aided Design, as it relates to software solutions for designing objects. CAE is an acronym for Computer Aided Engineering, as it relates to software solutions for simulating the physical behavior of future products. CAM is an acronym for Computer Aided Manufacturing, as it relates to software solutions for defining manufacturing processes and operations. In this CAD system, GUI plays an important role in technical effici...
