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
The present invention relates to the photocuring three-dimensional contouring method of product, especially for the SLA moulding process of high complex product (homocentric sphere).
Background technology
At present, the homocentric sphere of designing according to 3D software, directly CNC machine-shaping or pass through mold injection molding, can only be with the product separate machined, and then bond to together, but processing is too loaded down with trivial details like this, cost height and influence product surface fineness, be difficult to satisfy product requirement, this just needs a kind of novel processing mode to satisfy the processing request of this series products, improves the moulding process of complex product.
The basic principle of rapid shaping (RP) technology: directly the CAD mathematical model is generated three-dimensional entity model fast by the material accumulation method under the control of computer, wherein the process of comparative maturity is photocuring three-dimensional contouring (SLA-Stereolithography).This technology is raw material with the photosensitive resin, is the point by point scanning of track liquid towards resin with the Ultra-Violet Laser under the computer control by the profile of being scheduled to part each minute layer cross section, make the thin resin layer that is scanned the district produce photopolymerization reaction, thereby form a thin layer cross section of part.Finish when one deck solidifies, travelling table applies the new liquid resin of one deck so that descend one deck scanning to solidify again at the resin surface that originally was cured.Before being bonded in securely, new one deck that solidifies on one deck, so repeats to finish up to the manufacturing of entire product prototype.
When but traditional SLA makes the homocentric sphere series products, support and add morely, post processing is complicated and to influence product attractive in appearance, and this provides a kind of new manufacture craft to solve this type of problem with regard to needs.
Summary of the invention
Deficiency at the prior art existence, the object of the present invention is to provide the SLA moulding process of the three-dimensional homocentric sphere of a kind of photocuring, be with the moulding of 3D modeling software deisgn product, support manufacturing software supports the product STL data and layering is handled, the laser fast shaping machine loads data, working process parameter and the requirement of rapid shaping room environmental are set, make product.
In order to realize above purpose, the technical solution used in the present invention is: the SLA moulding process of the three-dimensional homocentric sphere of photocuring may further comprise the steps:
1), product design: utilize the 3D modeling software that the homocentric sphere product is carried out the 3D design; Derive its STL data;
2), loading data sets up support: open the STL data of homocentric sphere in support manufacturing software RPData, product is placed between two parties, facing down of product wall thickness arranged on each homocentric sphere, set up then and support, the support of lesser amt is set in the bottom surface of each ball;
3), the support manufacturing software hierarchy is handled; With the photosensitive resin is raw material, is the point by point scanning of track liquid towards resin with the Ultra-Violet Laser under the computer control by the profile of being scheduled to homocentric sphere each minute layer cross section, makes the thin resin layer that is scanned the district produce photopolymerization reaction, thereby forms a thin layer cross section of part; Finish when one deck solidifies, travelling table applies the new liquid resin of one deck so that descend one deck scanning to solidify again at the resin surface that originally was cured, new one deck that solidifies is bonded on preceding one deck securely, after layering was handled, analog equipment processing situation was confirmed back derivation product SLC file;
4), SLA loads the SLC data: the homocentric sphere product is opened SLA and is made software on laser fast shaping machine operation interface, load homocentric sphere SLC file then, and working process parameter is set;
Described technological parameter is: profile scan speed is 6000mm/s, and the filling sweep speed is 6500mm/s, and the support sweep speed is 1500mm/s, and laser power is 330mw.
5), SLA processing and fabricating product: the room temperature of working environment remains on 23 ℃, and humidity maintains below 40%, begins to make product;
6), cleaning: after completing, remove and support, product is through cleaning grinding and buffing, and homocentric sphere is made and finished.
7), check.
The present invention, the latter made hollow ball any surface finish of process modification, convenient post-treatment, and also with low cost, beautify product surface, increase product hardness.
Description of drawings
Fig. 1 is a process chart of the present invention.
Fig. 2 is that conventional method is added the support schematic diagram.
Fig. 3 is that schematic diagram is supported in interpolation of the present invention.
The specific embodiment
Known that by Fig. 1 the SLA moulding process of the three-dimensional homocentric sphere of a kind of photocuring may further comprise the steps: 1, utilize the 3D modeling software that product (homocentric sphere) is carried out the 3D design, design finishes, and derives its STL data.
2, in support manufacturing software (RPData), open the STL data of homocentric sphere, product is placed between two parties, and will facing down of product wall thickness be arranged on each homocentric sphere, set up then and support, following support that lesser amt need be set in the bottom surface of each ball of situation in this, and firm supporting, make things convenient for post processing, can reduce the cost of product again.(the supporting construction figure after the improvement sees accompanying drawing 2); After layering was handled, analog equipment processing situation checked whether the support of product is reasonable, whether has potential safety hazard, derives product SLC file after confirming.
3, on laser fast shaping machine operation interface, open SLA and make software, load homocentric sphere SLC file then, new working process parameter is set, profile scan speed is 6000mm/s, the filling sweep speed is 6500mm/s, and the support sweep speed is 1500mm/s, and laser power is 330mw, and the temperature in the room remained on 23 ℃, humidity maintains 40% can begin to make product when following.
4, after production was finished, through cleaning and polishing, homocentric sphere was promptly made and is finished.
Being known by Fig. 2, is that traditional approach adds support 1, and the top and bottom of hollow ball 2 all will add supports 1, though such support 1 is very firm, can cause hollow ball 2 poor surface smoothnesses, and difficulty increases during post processing, and manufacturing cost improves.
Know by Fig. 3, utilize 23 ℃ of the present invention, humidity maintains below 40%, laser power is increased (330mw), profile scan speed reduces (6000mm/s), fills sweep speed and reduces (6500mm/s), with this understanding, hollow ball 2 there is the placed face down of wall thickness, under each hollow ball 2, adds and support 1 and get final product.Draw through experiment, hollow ball 2 any surface finish that the present invention makes, convenient post-treatment, and also with low cost.
