Showa Denko Materials is one of only four companies in the world who manufactures DCPD (dicyclopentadienyl) monomers. These monomers have numbers of unique features inherent to the chemical structure itself.

Innovative Solution

Low cure shrinkage monomers improve dimensional accuracy of 3D printed objects

Fancryl 500 Series developed by Showa Denko Materials has a bulky DCPD structure that it contributes to low cure shrinkage when added to 3D print resin formulations. These products improve the dimensional accuracy of 3D printed objects with fine, complicated shapes.

Less oxygen sensitive monomers improve the yield rate of 3D print objects

Fancryl 500 Series is not affected by oxygen inhibition compared to other monofunctional aliphatic monomers. These products reduce the scrap rate caused by insufficient cure.
