  In this paper we are exploring the possibilities of 3D printing in the
fabrication of mirrors for astronomy. Taking the advantages of 3D printing to
solve the existing problems caused by traditional manufacturing, two
proof-of-concept mirror fabrication strategies are investigated in this paper.
The First concept is a deformable mirror with embedded actuator supports system
to minimise errors caused by the bonding interfaces during mirror assembly. The
second concept is the adaption of the Stress Mirror Polishing (SMP) technique
to a variety of mirror shapes by implemented a printed thickness distribution
on the back side of the mirror. Design investigations and prototypes plans are
presented for both studies.
