The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, 1, bracing frame, 2, container, 3, radiation source, 4, digital signal processing appts, 5, print supporting disk, 6, vertically control motor.
The specific embodiment
With reference to accompanying drawing, in conjunction with specific embodiments, the utility model is elaborated as follows.
Embodiment
As shown in Figure 1, comprise bracing frame 1, container 2, radiation source 3 and digital signal processing appts 4, the photoactive material of contain fluids state in container 2, print supporting disk 5 and immerse in container 2, the three-dimensional model printed for support; Bracing frame 1 supports radiation source 3 and digital signal processing appts 4; Select light source as radiation source 3, radiation source 3 is arranged in the top of container 2, direct irradiation digital signal processing appts 4, digital signal processing appts 4 is comprised of the micromirror matrix control system of machine, digital signal processing appts 4 is by the signal in reflected radiation source 3, every layer of information of three-dimensional modeling body is mirrored in the container 2 of splendid attire photoactive material, make photoactive material be become by liquid state solid-state.
Described bracing frame 1 bottom is provided with vertical control motor 6, vertically controls motor 6 and controls the height of printing supporting disk 5 by bracing frame.
The induction frequency spectrum of the optical spectrum of described radiation source and photoactive material coincide.Make photoactive material can in the short time, change states of matter.
The movement of described supporting disk highly determines the precision of printable layer.In the three-dimensional contouring technology, perpendicular to the z axle of printing in-plane, by vertical driven by motor supporting disk, controlled.After the fluent material on the x-y plane of a layer solidifies, the z axle is moved down by driven by motor.The liquid curing material covers curing part and forms the new curing printable layer that remains.Therefore, the each mobile distance of the printing dish of Z axis is less, and the layer density of Z-direction is higher, and its printing precision is higher.
Stereoforming method of the present utility model comprises the following steps:
Step 1, preparation is applicable to radiation source and the light sensation flowing material of stereolithography machine;
Step 3, be ready to projection image the supplied with digital signal treatment facility of every layer of three-dimensional model;
Step 4, open radiation source;
Step 5, solidify it by digital signal processing appts reflected radiation source to the light sensation flowing material;
Step 6, close radiation source and print supporting disk by vertically controlling motor removing;
Step 7, open radiation source and carry out solidifying of second layer material with this repeatedly;
Step 8, complete printing, closes radiation source.
The above is specific embodiment of the utility model and the know-why used, and any equivalent transformation based on the technical solutions of the utility model basis, within all belonging to protection domain of the present utility model.
