3D printing company ExOne says that a paper published in the peer-reviewed journal, Additive Manufacturing said that a roller system was important to the quality of metal 3D printed parts using binder jet technology.

The researchers, who cited the company’s M-Flex metal 3D printer, said the compaction of the powder layers was beneficial in minimizing the seeping of the liquid binder outside the intended part area. ‘This seeping out effect can be detrimental as it can lead to layer shifting,’ the paper said. ‘In fact, layer shifting is consistently observed in many of the samples printed with the deactivated roller rotation.’
