Las tolerancias en Impresión 3D

La impresión 3D no es un proceso perfecto. Como en cualquier otro sistema de fabricación, existen diferencias entre lo que diseñamos y el objeto físico que fabricamos. Estas pequeñas diferencias entre la computadora y el mundo real se llaman tolerancias.

Obtener una tolerancia 0 en el mundo físico es imposible, es por eso que hay ciertos valores de tolerancia que son aceptables y no afectan el funcionamiento de la pieza diseñada. Conocer las tolerancias aceptables para cada aplicación, así como las tolerancias con las que imprime su impresora 3D marca la diferencia entre una impresión exitosa y una falla.

Es por eso que en este artículo veremos cómo medir las tolerancias de su impresora 3D y cómo diseñar con esos valores en mente.

Cómo afectan las tolerancias a tus impresiones 3D

Conocer las tolerancias con las que puede imprimir su impresora 3D es esencial si va a diseñar piezas que interactúen entre sí. Cuando conoce estos valores, es mucho más fácil diseñar con suficiente holgura para que todas las partes se comporten como usted desea.

En artículos anteriores le hemos dado una guía de diseño básica para dejar la holgura necesaria de acuerdo con el comportamiento de las diferentes piezas. Puedes verlo en la siguiente imagen.

Cuando conoce las tolerancias de su impresora, puede ajustar estos espacios para mejorar el funcionamiento de las diferentes partes que conforman su diseño.

Cómo medir las tolerancias de su impresora 3D

Lo primero es calibrar tu impresora correctamente. En impresoras comerciales, este paso no suele ser necesario, pero en los kits de montaje es esencial. Para esto, es mejor realizar un cubo de calibración y ajustar los pasos de los motores hasta que la precisión de la máquina sea correcta. Hay cientos de modelos en internet para realizar este paso. Te recomendamos que uses lo siguiente:

También es importante calibrar el extrusor de impresora 3D y asegurarse de que la cantidad de material extruido sea correcta.

Una vez que tengamos la máquina calibrada, iremos a medir las tolerancias de nuestra máquina. Para ello imprimiremos 5 piezas del siguiente modelo, en impresiones separadas.

Una vez que se imprimen las 5 piezas, siempre tome medidas en la misma pieza y con la misma orientación de la pieza. Al restar el valor superior e inferior, puede conocer la tolerancia de su impresora. Realiza estas medidas en las tres direcciones de la pieza (X, Y, Z).

Diferencia entre tolerancia y holgura.

Ahora que conocemos las tolerancias de nuestra impresora, podemos diseñar teniendo en cuenta la holgura . La holgura es la separación mínima entre piezas que debemos dejar en el diseño. Como regla general, podemos suponer que será el doble del valor de la tolerancia obtenida.

Si aún desea saber qué valores de holgura son los que funcionan mejor para su diseño, puede probar el siguiente modelo para la impresión 3D .

Cómo mejorar las tolerancias de tus piezas impresas.

Mejorar las tolerancias significa reducirlas. Siempre es posible reducir estos valores, especialmente si son muy altos. Para esto hay una serie de pasos que debes seguir:

  • Verifique las partes móviles de su impresora: Si estas partes están dañadas, afectarán la calidad dimensional de sus impresiones. Revise los motores, correas y cojinetes y reemplácelos si es necesario.
  • Use filamento de calidad: un filamento de baja calidad dimensional llevará a una extrusión inconsistente, que afectará las medidas de su pieza.
  • Asegúrese de calibrar su impresora: una impresora mal calibrada es el mejor amigo de las malas tolerancias.

Y eso es todo por hoy.

Saludos y nos vemos imprimiendo.

      L'aggiornamento della sperimentazione sui test del PSA europeo offre poche indicazioni agli uomini americani
      Gli ultimi risultati dell'European Randomized Study of Screening for Prostate Cancer (ERSPC) hanno riscontrato un minor rischio di morte a causa del cancro alla prostata negli uomini sottoposti a screening con il test del PSA, rispetto agli uomini che non sono stati sottoposti a screening. Ma sfortunatamente questa scoperta non offre una guida chiara agli uomini americani che cercano di capire cosa significhi per loro il grande dibattito sui test del PSA.
