Embodiment Construction

[0053] Such as figure 1 As shown, the three-dimensional molding machine of the present invention includes a box 2, and the box 2 is suitable for containing a liquid substance 3, such as figure 2 As shown, the liquid substance 3 is adapted to solidify when subjected to a selective stimulus 4 .

[0054] The aforementioned selective stimuli 4 are produced by emitting means 5 delivering the stimuli 4 towards the tank 2 .

[0055] Preferably, but not necessarily, the liquid substance 3 is a photosensitive resin and the emitting means 5 comprise a laser emitter connected to any known type of scanning device 5a is associated.

[0056] Obviously, variant embodiments of the invention may contain other known types of emission means 5 as long as they are capable of solidifying the liquid substance 3 .

[0057] The machine 1 also comprises a molding plate 6 provided with a working surface 7 facing the launching means 5 and adapted to support the three-dimensional object A being shaped...

Abstract

The invention is a modelling plate (6; 6'; 6") for a stereolithography machine (1) suited to produce three-dimensional objects (A) through superimposition of a plurality of layers (E) with predefined thickness of a liquid substance (3) that solidifies when subjected to a selective stimulation (4). The plate (6; 6'; 6") comprises a work surface (7) that supports the object (A) and grooves (8) made in the work surface (7) along a development trajectory (X).

Description

technical field [0001] The present invention relates to a molding plate for a three-dimensional forming machine, and a three-dimensional forming machine including the plate. [0002] The invention also relates to a tool for cleaning the molded panels described above. Background technique [0003] As is known, stereolithography techniques can produce three-dimensional objects by superimposing successive layers obtained from liquid resins that solidify when subjected to predetermined stimuli. [0004] Each layer of the object is created by selectively stimulating the resin to cure at the points that make up the corresponding part of the object to be produced. [0005] As is known, a three-dimensional molding machine generally comprises a tank adapted to contain liquid resin, means adapted to stimulate a layer of liquid resin having a predetermined thickness, and a moving molding plate supporting it during the formation of the three-dimensional object. [0006] To form the fi...
