   Ceramic  MSL  differs  from  polymeric  MSL  in  the  following  aspects.  First,  the  resin
 system  for  ceramic  MSL is  composed  not  only  of the  monomers  and  photoinitiators  that
 are  used  in  polymer  MSL  but  also  of  ceramic  powders,  dispersants,  and diluents (Zhang
 et al.  1999;  Varadan et al.  1996). Dispersants  and diluents  are  used  to obtain  a  homoge-
 neous  ceramic  suspension  with a relatively low  viscosity. Upon  UV polymerisation,  the
 ceramic  particles  are  bonded  together  by  the  polymer  and  the  ceramic  body  is  formed.
