Para una pieza que tiene que encajar, elige una herramienta de CAD con IA que calcule la geometría a partir de tus medidas, no un generador de mallas: SpeakCAD para trabajar desde el móvil y obtener G-code laminado para tu impresora, CADAM, la herramienta de código abierto de AdamCAD, para alojarla tú mismo en un ordenador, Zoo para archivos STEP, STLsmith para ganchos y escuadras sencillos. Meshy, Tripo y MakerLab son mejores para figuras.
En parte. Gratis, sin tarjeta: la demo en directo (3 ediciones con IA de una pieza real, sin cuenta), abrir y redimensionar uno de los 650+ modelos listos de la biblioteca en una cuenta gratuita, y la pieza de prueba Fit Check en STL o 3MF. Describir tu propia pieza usa créditos: 4 créditos por una pieza nueva con un plan, sus 3 primeros cambios pequeños gratis (3 sin plan), 3 por un cambio de diseño, 2 por un cambio pequeño, 1 por una edición rápida (un tamaño o un número cambiado); la descarga está incluida en todos los planes (4 créditos sin plan). Maker cuesta 7,99 $ al mes por 50 créditos, cancela cuando quieras; Pro cuesta 14,99 $ al mes (200 créditos al mes, G-code laminado incluido).
No por sí solo: ChatGPT puede describir una pieza o escribir código OpenSCAD, pero no genera un archivo imprimible. Pega su descripción o su código en SpeakCAD (mira la página ChatGPT a STL) y obtendrás un STL, un 3MF o G-code laminado para tu impresora.
Para figuras y formas orgánicas: Meshy, Tripo o MakerLab. Para archivos STEP para un taller de mecanizado: Zoo, Backflip o Fusion 360. Para aprender CAD gratis: Tinkercad. Para código abierto y autoalojamiento: CADAM u OpenSCAD.
