## Abstract

A test system includes a computer, a 3D printer, and a test device. The computer obtains shape data which indicates a three-dimensional shape of a workpiece and material data which indicates a material of the workpiece. The 3D printer forms a structural object which has a three-dimensional shape that is indicated by the shape data. The test device performs a test on a pseudo workpiece which has been prepared by adding, to the structural object, a test piece made of the material that is indicated in the material data.

## Claims

### Claim 1

A test method comprising the steps of:
obtaining shape data which indicates a three-dimensional shape of a workpiece and material data which indicates a material of the workpiece;
forming a structural object which has the three-dimensional shape that is indicated by the shape data;
selecting, from among a set of test pieces given in advance, a test piece made of the material that is indicated by the material data which;
adding, to the structural object which has been formed in the structural object forming, the test piece which has been selected in the test piece selecting step; and
performing a test on a pseudo workpiece which has been prepared by adding, to the structural object, a test piece made of the material that is indicated by the material data.

### Claim 2 (depends on 1)

The test method according to claim 1, wherein
the step of performing the test includes the steps of:
performing surface processing on the pseudo workpiece; and
measuring a surface condition of the pseudo workpiece which has been surface-processed.

### Claim 3 (depends on 1)

The test method according to claim 1, further comprising the steps of:
generating the shape data;
providing the shape data and the material data; and
obtaining result data which indicates a result of the test.
