However, prototypes made with FDM o SLS may have slightly lower resolution and surface finish compared to the final product. Overall, Prototipado rápido offers enough accuracy to validate the design and functionality of a part, ensuring that the final product will meet the necessary specifications.
What are the limitations of rapid prototyping in the injection molding process?
While Prototipado rápido offers many benefits, it does have some limitations:
- Material Differences: The materials used in rapid prototyping may not always match the mechanical properties of the materials used in moldeo por inyección de plástico. This can affect how closely the prototype reflects the final part’s performance.
- Tolerances: Some Prototipado rápido technologies may not achieve the same high level of tolerances as moldeo por inyección de plástico. This can be an issue for parts that require precise dimensions.
- Escalabilidad: While Prototipado rápido is ideal for testing and small-batch production, scaling up to full production using moldes de inyección de plástico may introduce new challenges that were not apparent in the prototype stage.
