Device for three-dimensional printing of a small glass object

摘要

The invention proposes a device for printing in three dimensions a glass object, by application and solidification of successive layers of a material constituting the glass, in locations corresponding to the section of the object to be produced in the layer. corresponding, by means of a laser 8 producing a beam whose wavelength allows direct fusion in the core of the material. The device comprises: - means for supplying the material to a support on which the successive layers are formed; - thermal regulation means of the successive layers for their temperature maintenance during the realization of the object and for their cooling after the realization of the object; - a central unit controlling the laser; said thermal regulation means being controlled by the central unit and maintaining the layers of the object at a maintenance temperature between the glass transition temperature of the material minus 100 ° C and the softening temperature of the material.
