   Nope, silicone rubber once cured has no melting point. 300 C is the maximum   
   temperature it can withstand before permanetly degrading. Silicone rubbers   
   in general have poor resistance to steam, super heated water, oils, fuels   
   and solvents.   
      
   Silicone rubbers would be impractical to 3D print due the the chemistry.
