Sedimentation stabilized radiation-curable filled compositions |
摘要 |
The present invention relates to a process for the production of three-dimensional articles by stereolithography using a radiation-curable composition containing a mixture of at least one cationically polymerizable compound and/or at least one free radical polymerizable compound, at least one filler material, at least one photoinitiator for cationic and/or radical polymerizations and at least one antisedimentation agent. An organic viscosity stabilizer material soluble in the base resin may optionally be brought into contact with the composition. A filler material can be introduced in the composition in an effective amount sufficient to at least delay or prevent a significant viscosity increase. The present invention also relates to cured articles resulting from said processes and a process for preparing said compositions. |
