Rapid development and efficient construction of product model can obtain good design efficiency at the same time. In the creation stage of design, the two-dimensional representation based on drawing is often used, but in the later stage, the representation of design will be more specific, and the specific visual model should be used as the object of discussion. Compared with the planar two-dimensional performance, the hand model has irreplaceable advantages.
Because of its visibility and touch, the prototype can directly reflect the designer's ideas and concepts in the form of physical objects.
Painting is not good-looking or better avoided. Therefore, the model research of prototype is often in the process of considering the shape of new products.
Generally speaking, the production cost of mold is relatively high. Some students majoring in mold design can reach hundreds of thousands of yuan or even millions. And once any dissatisfaction is found after production, it needs to be done again. This loss can be made up for. Therefore, the hand model can avoid the technical defects of the traditional mold, and has attracted more and more attention from the market.
The prototype model can make the details of the product clearer, and the visual experience of the product can be very intuitive. Everyone in the design team can see these designs, which has obvious advantages in coordinating the work of the whole team. The prototype is used for design discussion. Compared with the two-dimensional plan, the 1:1 hand model is more intuitive. Designers can feel the design effect through direct contact, so that the discussion of design modeling is based on a more realistic basis. It is irreplaceable for plane drawings.
After the prototype is made, if painting is required, it should be noted that the workpiece formed by SLA laser is not suitable for surface highlight treatment, because the material used in SLA is photosensitive resin, and the paint from the prototype is not very good. The gloss effect is not very good. The workpiece processed by CNC, including PP and POM materials, is not suitable for surface coating, and the material has no adhesion to the paint.
Shandong rapid prototyping manufacturers remind that sandpaper should be used before painting. There are several types of sandpaper, including coarse sandpaper and fine sandpaper. The workpiece can be ground with water. Use fine sandpaper, and then you can sand blast and spray the bottom. The high gloss treatment needs to be polished more finely, and then sprayed with a layer of primer for polishing.
According to the production site of the specific prototype factory and the surface of the workpiece processed by the 3D printing prototype, the main purpose of adopting physical means is to eliminate the control factors affecting the processing quality and cycle in chemical treatment and maintain the service life of chemical agents. For example: deal with too much oil, dust, iron, rust and floating rust. The oxide scale is too thick to be cleaned manually (mainly steel wire brush and abrasive cloth). Remove rust and dust with compressed air.
