Embodiment Construction

[0019] Depend on figure 1 Known, a kind of SLA molding process of light-cured three-dimensional concentric sphere, comprises the following steps: 1, utilize 3D modeling software to carry out 3D design to product (concentric sphere), design finishes, export its STL data.

[0020] 2. Open the STL data of the concentric spheres in the support production software (RPData), place the product in the center, and place the side with the product wall thickness on each concentric sphere facing down, and then build the support. The bottom surface of each ball is provided with a small number of supports, and the supports are firm, which is convenient for post-processing and can reduce the cost of the product. (The improved support structure diagram is shown in the attached figure 2 ); After layered processing, simulate the product processing situation, check whether the support of the product is reasonable, and whether there are potential safety hazards, and export the product SLC file ...

Abstract

The invention discloses an SLA (stereo lithography) technology of a light curing stereo homocentric sphere which is characterized by comprising the following steps: 1) designing product; 2) loading data and establishing support; 3) carrying out layering treatment on an RPDate; 4) loading SLC data based on SLA; 5) processing and manufacturing products based on SLA; 6) clearing; and 7) inspecting. In the invention, hollow sphere manufactured after process improvement has a bright and clean surface and is convenient to post process, furthermore, the cost is low, the product surface is beautified, and the product hardness is increased.

Description

technical field [0001] The invention relates to a light-cured three-dimensional modeling method for products, especially an SLA molding process for highly complex products (concentric spheres). Background technique [0002] At present, the concentric spheres designed by 3D software cannot be directly CNC processed or molded by injection molding. The products can only be processed separately and then bonded together. However, this processing is too cumbersome, high cost, and affects the surface finish of the product. , It is difficult to meet the product requirements, which requires a new processing method to meet the processing requirements of such products and improve the molding process of complex products. [0003] The basic principle of rapid prototyping (RP) technology: under the control of the computer, the CAD digital model is directly and rapidly generated into a three-dimensional solid model through the material accumulation method. The more mature process method is...
