Hybrid furnace solutions for thermal post-processing in Additive Manufacturing

With the new LH..DB series, Nabertherm offers a versatile solution that is tailored to the requirements for thermal post-processing of 3D-printed components. Thanks to the flexibility of the furnace series, the range of applications also includes the debinding and sintering of conventionally manufactured ceramics on a laboratory scale.  

Versatile and compact

For the development of this furnace series, particular focus was given to the heat treatment processes in Additive Manufacturing. The aim was to create a furnace solution that can be used independently of the material. The LH..DB series is therefore not limited to debinding and sintering processes in air: As a hybrid solution, processes under non-flammable process gasses can be performed with the optional protective gas box. This allows debinding of 3D-printed components made of metal or other materials requiring an inert atmosphere up to 600 °C. Subsequent heat treatment under inert gas is possible up to 1100 °C. 

The furnace series is available in two different sizes with oven volumes of 120 and 216 liters. This allows heat treatment of all platform sizes of the current 3D printers for binder-containing material systems. In addition, the LH..DB furnace impresses with their compact design. The controller, control elements, automatic gassing system, and switchgear are integrated directly into the furnace housing. Once connected to the power supply, the furnace is immediately ready for use.

Safety through proven technology

The DB debinding package ensures safety during debinding. During processes in air, preheated fresh air dilutes the escaping binder gases so that no ignitable atmosphere is created. During inert debinding, the safety package monitors the gas flow of the gassing system and ensures reliable purging of the protective gas box. In addition, the furnace chamber is purged with preheated fresh air independently of the process. This improves the heat transfer into the charge and ensures uniform debinding.
