| Abstract Scope |
Binder jetting is faster than laser-based AM technologies, which enables the required throughput for the mass production of metal components. However, binder jetting requires several post-processing steps, such as curing and de-binding, which increase production costs. This study aims to establish an in-process curing method to reduce the production time of binder jetting printed parts using heat sources. Three different models based on FEM were developed to thermally simulate in-process curing during binder jetting. In the first model, the heat source moves incrementally over the powder bed. The second model integrates the heat input over each deposited powder layer, reducing computational time. In the third model, a lumped approach is employed, allowing for the grouping of several layers, thereby improving computational efficiency. The three models are compared with experimental measurements, their accuracy and computation times are also evaluated. |
