Talking about prototype technology of SLA laser forming

Laser Rapid prototyping machine is the principle of forming by material accumulation. Controlled by a computer, about 0 per layer. The thickness of 1mm is accurately scanned by laser, and the material is superimposed layer by layer ( Photosensitive liquid resin can be cured quickly under the irradiation of UV laser), Rapid prototyping accuracy of ±0. Product prototype of 1mm. Because there is no need to install and remove the workpiece, there is no need to change the tool, so as to ensure the accuracy of the product. The process takes only a few days or even hours (To determine the size of the product shape).

The manufacturing process of sla laser forming prototypes is also an important part of ensuring the quality of prototype models, the processing method and machining accuracy in the prototype model manufacturing process will also affect the service life of the prototype model. The accuracy of each component directly affects the overall assembly of the prototype model. To remove the influence of the accuracy of the equipment itself, it is necessary to improve the processing method of the part, improve the technical level of the fitter in the grinding process of the prototype model to improve the machining accuracy of the prototype model parts; If the overall assembly effect of the prototype model does not meet the requirements, the probability of the prototype model moving under abnormal conditions will be improved in the trial model, which will have a great impact on the overall quality of the prototype model.

in order to ensure that the prototype model has good original accuracy- The quality of the original prototype model, in the manufacturing process, we must first select the high-precision machining methods, such as EDM, wire cutting, CNC machining, etc. , and pay attention to the accuracy inspection of the prototype model, including the machining accuracy, assembly accuracy of the prototype model parts and the accuracy of the prototype model through the test mold acceptance work, the high-precision measuring instrument should be selected as far as possible during the inspection, for those prototype model parts with complex surface and surface structure, if the ordinary ruler and label card are used, the accurate measurement data cannot be achieved. At this time, a precision measurement equipment such as a three-Coordinate Measuring instrument is required, to ensure the accuracy of the measured data.

CNC precision machining is a traditional way of cutting off excess materials by means of place. It is commonly used in prototypes of mobile phones, PDA, digital cameras, small household appliances and peripheral products of electronic computers, and can also make standard parts for functional testing of large and complex products, such as air conditioning, color TV, electronic piano, display, audio, medical equipment, motorcycles, auto parts and other products.

In the traditional processing industry of prototypes, CNC machining is generally aimed at some large workpieces and appearance plates, and the processing materials are extensive, ABS, PU, PA (Nylon) PC, PVC, PP, PE, POM (Saigang)Asian force (Transparent material)Wait; CNC has low cost, high strength, high temperature resistance, high toughness, transparency and other requirements for processing materials, and can also make metal samples such as aluminum alloy; Moreover, the CNC model processing forms are eclectic, such as polishing, Ash spraying, painting, polishing, silk screen printing, electroplating, etc (Especially models that need plating) The effect is completely comparable to the products produced by the mold; In appearance, assembly, functional verification, can achieve customer design intent. Therefore, CNC model making has become one of the mainstream of modern prototype processing.

correct use and maintenance of sla laser forming prototypes is also a major factor in improving the quality of prototype models. For example, the installation and commissioning of the prototype model should be appropriate. In the case of hot runner, the power supply wiring should be correct, and the cooling waterway should meet the design requirements, in the production of the prototype model, the parameters of injection molding machine, die casting machine and press should be in line with the design requirements and so on.
