- This may be effective in reducing the cost and weight of the model.
When printing with the 3DUJ series, the inside of the model is printed with modeling ink, but by making the model hollow, it is printed with a support material that is less expensive than modeling ink.
Furthermore, if an "escape hole" is drilled or created with separate 3D data editing software after modification, it is possible to reduce the overall weight of the model by draing the support from inside the model..
