Cómo funciona la impresión 3D SLM
Fusión selectiva por láser (SLM): un enfoque revolucionario de fabricación aditiva de metales
Selective Laser Melting (SLM) is an advanced metal 3D printing technology that was first proposed by the Fraunhofer Research Institute in Germany back in 1995. Unlike the traditional Selective Laser Sintering (SLS) process, SLM enables the direct formation of near-fully dense metal parts through the selective melting of metal powders.
The key advantage of SLM over SLS is the elimination of the complex manufacturing steps required for metal parts. In the SLM process, the metal powder is instantaneously melted and solidified (with a cooling rate of approximately 10,000 K/s), resulting in a large temperature gradient and significant residual stresses within the part.
Sin embargo, este rápido proceso de fusión y solidificación puede plantear problemas de deformación del sustrato. Para superarlo, el sustrato debe ser lo suficientemente rígido como para soportar la influencia de las tensiones residuales. El recocido de alivio de tensiones puede emplearse para eliminar la mayoría de estas tensiones residuales, evitando una deformación excesiva del sustrato debido a una rigidez insuficiente.
La capacidad de la SLM para fabricar directamente piezas metálicas de densidad casi total, sin necesidad de pasos de fabricación complejos, la ha convertido en una tecnología valiosa en diversos sectores, como el aeroespacial, la automoción, el médico y otros. Al aprovechar la precisión y la flexibilidad de diseño de la SLM, los ingenieros y fabricantes pueden ampliar los límites de lo que es posible en la fabricación aditiva de metales.

Ventajas de la fabricación aditiva de metales por láser
-El haz láser puede fundir rápidamente el polvo metálico y obtener una trayectoria de soldadura continua, que puede obtener directamente casi cualquier forma;
-The fabricated metal parts have high dimensional accuracy, good surface quality and nearly 100% density;
-Compared with the traditional process, it basically does not need subsequent reprocessing, which can greatly shorten the processing cycle, avoid material waste and reduce the expensive mold cost;

Mold steel is a kind of steel used to manufacture cold stamping die, hot forging die, die casting die and so on. As the mother of industry, the quality of die directly affects the quality of pressure machining process, product accuracy, output and production cost. In addition to reasonable structural design and machining accuracy, the quality and service life of die are mainly affected by die material and heat treatment. The hardenability of traditional process is poor, and it will be scrapped once cracked in the process of quenching. With the participation of 3D printing technology, the formed die grains can be improved in the process parameters, which directly improves the mechanical performance. 3D printing is processed by laser. The die steel obtained after high-speed cooling is very uniform, and hardly needs to go through the quenching process. It can be used after the internal stress is released after heat treatment.
Titanio y aleaciones de titanio
Titanio and titanium alloys have the remarkable characteristics of high specific strength, heat resistance, corrosion resistance and good biocompatibility. They have become ideal materials in the fields of medical devices, chemical equipment, aerospace and sports equipment. Titanium alloy is a typical difficult to machine material, which has high stress, high temperature and serious tool wear, which limits the wide application of titanium alloy. 3D printing technology is especially suitable for the manufacture of titanium and titanium alloys. When 3D printing is carried out in a protective atmospheric environment, titanium is not easy to react with oxygen, nitrogen and other elements. At the same time, the rapid heating and cooling of local micro areas also limit the volatilization of alloy elements; Second, complex shapes can be manufactured without cutting. Based on the high utilization rate of powder or wire, it will not cause waste of raw materials and greatly reduce the manufacturing cost. At present, the types of 3D printed titanium and titanium alloys include pure titanium, Ti6A14V (TC4) and ti6a17nb, which can be widely used in aerospace parts and artificial implants (such as bones, teeth, etc.).
