Abstract Scope |
HP’s Multi Jet Fusion (MJF) is a powder-based technology that selectively melts polymer powder, using a fusing agent, in a layer-by-layer fashion to create 3D parts. One of challenges for wide adoption of additive manufacturing is the assurance of the print process and part consistency through a cost-effective and non-destructive fashion. Here, we showcase a method to print two-dimensional patterns at desired locations throughout the part. The readability of the pattern can provide either the signals to take action during the print process or information on part quality during and after printing, thus non-destructive part quality measurements can be achieved. This method can also be used for covert part marking to provide design intellectual property security. |
