Styrotec offers a Hybrid-Technology with the Large Format Additive Manufacturing "LFAM" which extends the CNC milling machine with a extrusion head on the Z-Slider for large area 3D printing. This enables new possiblities to realize components.
The printing of big forms before CNC machining leads to less waste then if you were to use usual PU blocks. The energy and time expense is lower and also it is more environmentally friendly because the left over material can be recycled.
