› 1995 - 2007 The AM parts were purchased from external suppliers.

› 2007 Set up of the own production

Machines: 5 SLA 1 SLS

› 2008 - 2018 Due to the rising demand of AM parts, the machine park had to be extended constantly.

Machines: 6 SLA 6 SLS

› 10/2017 Start of the set up of the new Metal AM Center

› Today Two Additive Industries MetalFab1 Basic Systems are implemented successfully.

› Near Future Both MetalFab1 are going to be extended with an additional core and a storage module
