Abstract
A shaping system that fabricates a shaping object by stacking a material layer formed based on slice data, the shaping system comprises a control section which controls operations of respective sections of the shaping system. The control section controls the respective sections so that, at a prescribed timing, a marker is formed and stacked on a top surface of a marker support body, image distortion information is acquired from a position of the marker as detected by a marker position detecting section, and a correction process for correcting the slice data is executed.
Claims19
A shaping system that fabricates a shaping object by stacking a material layer formed based on slice data, the shaping system comprising:
- a control section which controls operations of respective sections of the shaping system;
- a marker generating section which generates data of a marker;
- a slice data generating section which generates the slice data by adding data for fabricating a marker support body to become a base on which the marker is stacked to data of a three-dimensional model;
- a material layer forming section which forms a material layer made of a shaping material based on the data of the marker or the slice data;
- a stage on which the material layer is stacked;
- a marker position detecting section which detects a position of the marker stacked on the stage or the marker support body;
- an image distortion acquiring section which acquires information on image distortion occurring in the material layer from a detection result of the marker position detecting section;
- and
- a correcting section which reduces the image distortion with respect to the slice data based on the image distortion information acquired by the image distortion acquiring section, wherein
- the control section controls the respective sections so that, at a prescribed timing,
- the marker is formed and stacked on a top surface of the marker support body, image distortion information is acquired from a position of the marker as detected by the marker position detecting section, and a correction process for correcting the slice data is executed.
A shaping object manufacturing method that repetitively performs, a plurality of times, a set of
- a material layer forming step of forming a material layer made of a shaping material based on slice data generated from three-dimensional model data and
- a shaping step of sequentially stacking the material layer formed in the material layer forming step, wherein
- a correction process step of correcting the slice data is inserted between each repetition of the set.
A data processing method used in a shaping system which fabricates a shaping object by performing, a plurality of times, a step of forming a material layer made of a shaping material based on slice data and a step of stacking the material layer, the data processing method comprising the steps of:
- generating data of a marker for acquiring information used to correct the slice data;
- and
- generating the slice data by adding data for fabricating a marker support body to become a base on which the marker is stacked to data of a three-dimensional model, wherein
- when data of the marker is inserted between the plurality of times of performing the step of forming the material layer, a step of providing an opening corresponding to a shape of the marker in slice data of the material layer formed subsequently to the insertion of the data of the marker is performed.
