specific Embodiment approach

[0015] The specific embodiment: the present invention will be further described below in conjunction with accompanying drawing:

[0016] Such as figure 1 As shown, the present invention provides a model optimization material-saving method of stereolithography technology, this method is to reduce the amount of materials by shelling the three-dimensional model; the specific shelling method is to give the three-dimensional model a certain shell wall Thick, that is, the shell is extracted from the surface of the model to the inside. And after a certain shell wall thickness is given, the model must be punched, that is, the outside of the printed model cannot be closed, that is, the depth of the hole must penetrate through the shell wall thickness, so as to ensure that the printed solid model is hollow.

[0017] The steps of this method are as follows:

[0018] (1) Take the minimum space volume of the pre-printed model, and then set the maximum shell thickness. The maximum shell t...

Embodiment

[0026] 1. The printed model is a handicraft pig. Through measurement, the pig's mouth 1 is the smallest space volume, and the maximum shell thickness should be smaller than the minimum radius of this part, so as to ensure that the pig's mouth is a hollow entity.

[0027] 2. After giving the model a certain shell wall thickness, the model must also be drilled. The depth of the hole must meet the depth of the wall thickness, otherwise the printed entity is not hollow, such as figure 1 Print entity 2 as shown.

[0028] 3. figure 1 Printing entity 3 is a hollow part, which is filled with a large amount of support material, the purpose of which is to save and support the entity material.

[0029] 4. figure 1 The 4 parts of the printed entity are the shell wall thickness. Different thicknesses are selected according to different situations. The smaller the shell thickness, the greater the material saving.

[0030] Table 1 shows the relationship between the amount of consumables a...

Abstract

A model optimization material-saving method of a stereo photocuring molding technology is characterized in that according to the method, the material utilization amount is reduced in a manner that a three-dimensional model is shelled; according to the specific shelling manner, a certain shelling wall thickness is given to the three-dimensional model, and shelling is carried out from the surface of the model to the interior of the model; after the certain shelling wall thickness is given, the model is punched, that is, the exterior of a printing model cannot be sealed, the punching depth needs to penetrate the shelling wall thickness, and it is ensured that a printed solid model is hollow; and a large number of materials for printing can be saved, and therefore the printing cost is greatly reduced, and application and popularization of the stereo photocuring molding technology are facilitated.

Description

technical field [0001] The invention relates to a model optimization and material saving method of stereolithography molding technology, which belongs to the field of rapid prototyping technology. Background technique [0002] Stereolithography is one of the earlier technologies used in 3D printing because of its high dimensional accuracy, excellent surface quality, and ability to print complex structural models. The materials used in the stereolithography technology are liquid photosensitive resin and paraffin wax, both of which complement each other and work together in the printing process, and both are indispensable. The surface and the hollow part are protected by a large amount of paraffin support, and the rest is made of solid material to print the solid part. The principle of stereolithography technology: use laser to focus on the surface of the solid material, so that the material is cured in a certain order, and after completing the "curing" of the current layer, ...
