Abstract

SE DISPONE UN PROCEDIMIENTO PARA PREPARAR UN OBJETO TRIDIMENSIONAL TAL COMO UN MANDRIL PARA FORMAR ENVUELTAS PARA PROTESIS MAMARIAS U OTRO DISPOSITIVO MEDICO INJERTABLE, SUMERGIENDO EL MANDRIL, ETC. LAS ENVUELTAS SE PROPORCIONAN CON MICROPILARES SOBRE LA SUPERFICIE EXTERIOR, QUE PARECE LA SUPERFICIE DEL MANDRIL EN RELIEVE NEGATIVO. DE CONFORMIDAD CON EL PROCEDIMIENTO, SE DISPONE UNA PIEZA A MAQUINA DE MATERIAL SOLIDO EN EXISTENCIA, TAL COMO POLIMERO, EN FORMA DE LA PROTESIS DESEADA. SE POSICIONA PARA ROTACION SOBRE UN EJE DE SOPORTE U OTRO MECANISMO DE SUSTENTACION. UN HAZ LASERICO DE IMPULSOS, DIRIGIDO A LA PIEZA A MAQUINA, SE DESPLAZA EN UN PLANO PARALELO AL EJE DE ROTACION DE LA PIEZA A MAQUINA, MIENTRAS SE MANTIENE EL HAZ APROXIMADAMENTE PERPENDICULAR A LA SUPERFICIE DE LA PIEZA A MAQUINA. LA FRECUENCIA DE LOS IMPULSOS DEL HAZ LASERICO Y LA VELOCIDAD DE ROTACION DE LA PIEZA A MAQUINA SE CONTROLAN PARA OBTENER PATRONES DE MICROAGUJEROS CIEGOS SOBRE LA SUPERFICIE DE LA PIEZA A MAQUINA. PUEDE OBTENERSE UN PATRON NO CIRCULAR MEDIANTE LA OSCILACION DEL HAZ HACIA, Y SEPARADO DE, EL EJE DE ROTACION, CON CADA REVOLUCION DE LA PIEZA A MAQUINA.
