The electrostatic latent image of the positive and negative graphical information image of lower semisphere passes through magnetic brush successively, adsorbs ball material, and model work is fallen into after pressurization
In platform, the positive and negative figure of lower semisphere is paved into respectively, completes one layer of printing；Successively printed by above step, until whole lower semisphere
Body printing is completed, and after heating makes each layer mutually merge, cooled and solidified is into the lower hemisphere with hemispherical cavity；It will be ready to
White material fill into the cavity of lower hemisphere；Printing and making upper hemisphere in the same manner, formed with lower hemisphere whole
It is individual filled with the hollow microsphere expected in vain.
Preferably, step（1）In leftover pieces crush after size be 10-20 mesh.
The size of leftover pieces after being pulverized in the present invention is controlled in 10-20 mesh, can either be ensured and hot melt powder
Uniformly mixing, while can also ensure that there is certain filling effect as inserts.
Preferably, step（1）The mass ratio of middle leftover pieces and the hot melt powder of addition is 2~3:1.
Preferably, step（10）The white material of middle filling is not higher than 80% of hemispherical cavity height in lower semisphere.
It is that will not should be deformation during upper hemisphere fusion spills to ensure to fill the lower hemisphere after white material, the present invention
The height of the white material of middle filling keeps being not higher than 80% of hemispherical cavity height in lower semisphere.
The present invention carries out twice laid compared with prior art, by leftover pieces caused by cutting sheet material, can not only reduce
Production cost, while being capable of the perfect inserts as polyurethane sheet；Produced by this method hollow filled with expecting in vain
Microballoon precision is high, and quality is outstanding, and added to that can be merged completely with black material during heating stirring in black material, ensure that polyurethane
The quality of production of plate.
