Predicting crystallinity of polyamide 12 in multi jet fusion process
Journal of Manufacturing Processes, 2023In multi jet fusion process, the thermal history varies at different locations inside the printing chamber resulting in the dependence of crystallinities of the printed parts. As performing experimental test is time consuming and costly, it is desirable to have the crystallinity be predicted even before the parts are printed. Thus, this work presents a

Modelling of the capillarity effect for cylindrical shapes in Multi Jet Fusion technology
Progress in Additive Manufacturing, 2021Multi Jet Fusion is one of the most productive additive manufacturing technologies available on the market. This important characteristic, together with the almost isotropic mechanical resistance of fabricated products, attracts the interest of users and industries. Despite those significant advantages, parts can present some specific defects.

A finned-riser design to avoid the capillarity effect in multi-jet fusion technology
Rapid Prototyping Journal, 2020Purpose Multi-jet fusion (MJF) process is based on a polymeric powder bed that is heated and irradiated by infra-red lamps. The layer under construction is jetted with inks to provide the desired heat management conditions for selective melting. Depending on several process variables, manufactured parts can exhibit lifting of the borders of the top ...

Springs are mechanical devices which are used quite extensively in different industries and mechanisms. Traditionally, springs have been manufactured by wrapping a hot wire around a rotating mandrel. This process has certain limitations because it is difficult to vary the spring parameters such as pitch and wire diameter. However, through the use of AM
