Additive manufacturing is a manufacturing technology that is gaining more and more ground among metallurgists. The process involves all the techniques used to create 3D metal objects from a digital design.

The notable increase in the world of metal additive manufacturing of the use of methods such as the Metal Injection Molding (MIM), the Binder Jetting (BJ) and the Fused Deposition Modeling (FDM), prompted TAV VACUUM FURNACES to design and install a vacuum furnace for thermal debinding in its Research and Development laboratory, in order to experiment the best solutions for this delicate post-production phase.

Let's find out what debinding is, how it is obtained and above all which are the most suitable tools to create high quality components without risking contamination.

Additive manufacturing and vacuum heat treatments are technologies capable of making important progress in various sectors, including dentistry applications.

In this case study carried out in collaboration with industry and Italian academy excellences, we will see the role of 3D printing in the medical-dental field and discover the benefits of post-printing vacuum heat treatments.

The final results are of a precision never known before with the more traditional procedures, while the mechanical and geometric advantages are innumerable.

In the previous article we’ve seen how AlTiN thin film deposition process was carried out via reactive Physical Vapor Deposition High-Power Impulse Magnetron Sputtering (PVD HiPIMS) to coat Ti6Al4V substrates, realized via Selective Laser Melting (SLM).
Two different SLM process conditions were employed for modifying the obtained part surface morphology and, later, the samples were heat-treated under high vacuum.

Do not miss this in-depth investigation and the conclusions at the end, we’ll provide you all the information to get the most out of these three technologies.

Among the industrial AM technologies, selective laser melting (SLM) is the most widespread, thanks to its process stability and its favorable ratio between costs and part quality. However, selective laser melted products require coatings for functionalizing the surface with extra properties and in this article we’ll see how thin film deposition process can be carried out to coat titanium substrates.

Is it possible to coat the titanium alloy substrates to obtain a good improvement of the mechanical surface features?
What’s the role of vacuum heat treatments on additive manufactured parts?
Can the laser scanning paths affect the resulting adhesion of the coatings?

Die additive Fertigung (AF) ist eines von vielen Verfahren zur Herstellung dreidimensionaler Festkörper auf Grundlage einer digitalen Datei.
Im Unterschied zu subtraktiven Fertigungsverfahren, bei denen das Ausgangsmaterial ein fester Materialblock ist, von dem so lange Material abgetragen wird, bis das Endprodukt fertiggestellt ist, wird bei der additiven Fertigung das Teil (bzw. einzelne Elemente auf Teile) Schicht für Schicht aufgebaut, basierend auf einer Geometrie, die in einem 3D-Design-Modell beschrieben ist.

Erfahren Sie, wie additive Fertigung mit Metallen das Design und die Produktion von leichten Metallteilen in Echtzeit ermöglicht und welches Potenzial Vakuum-Wärmebehandlungen für im 3D-Druck entstandene Teile bieten.
