Nabertherm adds LH..DB furnace line for thermal post-processing in Additive Manufacturing
Nabertherm GmbH, headquartered in Lilienthal, Germany, has introduced its LH..DB furnace range, tailored for thermal post-processing of metal additively manufactured components, as well as the debinding and sintering of ceramic parts.
The furnace series is available in two different sizes, with oven volumes of 120 and 216 litres. This is said to allow heat treatment of all platform sizes of the current binder-based Additive Manufacturing machines. The LH..DB furnace is compact, with the controller, control elements, automatic gassing system, and switchgear integrated directly into the furnace housing. Once connected to the power supply, the furnace is immediately ready for use.

The LH..DB series is not limited to debinding and sintering processes in air: as a hybrid solution, processes under non-flammable process gases can be performed with the optional protective gas box. This allows debinding of additively manufactured 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 1,100°C.
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, improving the heat transfer into the charge and ensuring uniform debinding.
Specifications on each model in the new LH..DB series are available on the company website.
