Traditional manufacturing machines cannot easily integrate multiple raw materials in the process of cutting or mold forming. With the development of multi material 3D printing technology, we have the ability to integrate different raw materials. Raw materials that cannot be mixed before will form new materials after mixing. These materials have a wide range of colors and unique properties or functions. When using 3D printing for the first time, there are various processes and materials to choose, so which process materials should we choose?
The following aspects are usually considered: cost, appearance, details, mechanical properties, mechanical properties, chemical stability, and special application environment. Although there are various factors, based on the production purpose of the model, it can be roughly divided into two categories: appearance verification model and structure verification model.
Appearance verification model: a prototype model designed and produced by engineers to verify the product appearance or a model directly used and with high requirements for appearance. The appearance verification model is visual and touchable, which can directly reflect the designer's creativity in the form of real objects, avoiding the disadvantage of "beautiful drawing but not beautiful making". Appearance verification model making is essential in the process of new product development and product appearance elaboration.
Based on the requirements of the appearance verification model, it is recommended to select photosensitive resin 3D printing (including high-precision and high toughness ABS and transparent PC materials);
Structure verification model: In the process of product design, from design scheme to mass production, it is generally necessary to make molds. The cost of mold manufacturing is very high, and the relatively large mold is worth hundreds of thousands or even millions. If the unreasonable structure or other problems are found in the mold opening process, the loss can be imagined. Therefore, making the structural verification model can avoid this loss and reduce the mold opening risk.
Based on the requirements of structural verification model, if the requirements for precision and surface quality are not high, it is recommended to select materials with good mechanical properties and low prices, such as PLA, ABS and other materials.
In addition, there are some special requirements. For example, if there is a requirement for conductivity, metal materials are required, or if you want to reverse make a beautiful jewelry, it is recommended to use paraffin wax.
