¿Qué es la impresión 3D?
La impresión 3D, o fabricación aditiva, es una tecnología innovadora que construye objetos tridimensionales a partir de archivos digitales. El proceso añade material capa a capa hasta conseguir la forma final. A diferencia de la fabricación tradicional, que suele cortar material de un bloque más grande, la impresión 3D permite crear geometrías complejas y detalles finos con un desperdicio mínimo. Se utiliza ampliamente en diversos sectores, como la creación de prototipos, el desarrollo de productos, los implantes médicos y la industria aeroespacial. Con sus ventajas en personalización, velocidad y rentabilidad, la impresión 3D es una herramienta clave en la fabricación moderna.
Comprehensive 3D Printing Quality Control & Inspection
At Lewei Precision, the quality and accuracy of each 3D printed component are our main concern. We will inspect all the parts to the highest standards of dimensional accuracy with the help of sophisticated inspection equipment, including CMM (Coordinate Measuring Machines), optical scanners, and digital micrometers. We are either ordering a prototype or a part that is production grade and this precision is ensured by our careful inspection process to ensure that you get the accuracy that you require in your 3D printing work.
Besides dimensional accuracy, we also comply with GD&T (Geometric Dimensioning and Tolerance) standards, which will guarantee that both dimensional and geometric accuracy conforms to ISO 2768-mK, and ASME Y14.5. We also perform detailed surface testing to verify Ra 3.2–0.8 μm roughness and confirm coating thickness. To provide full transparency, we offer comprehensive traceability through Material Certificates (MTRs), FAI reportsy CMM data sheets, ensuring that all your parts meet industry regulations and your specific needs.
