  Optical fibre is drawn from a dual-head 3D printer fabricated preform made of
two optically transparent plastics with a high index core (NA ~ 0.25, V > 60).
The asymmetry observed in the fibre arises from asymmetry in the 3D printing
process. The highly multi-mode optical fibre has losses measured by cut-back as
low as {\alpha} ~ 0.44 dB/cm in the near IR.
