Chemical surface preparation specifically for stereolithography (SLA) polymers prior to its metallization is reported for the first time in the present paper. Contact angle analysis was conducted to assess the surface hydrophilicity so as to optimize the preparation process. The applicability of this technology was verified by subsequent metallization process. This introduces an efficient method for metallization of SLA polymers and enhances its performances in applications. X-ray diffraction (XRD) and atomic force microscopy (AFM) image analysis were applied to understand the phase composition and the micromorphologies of the substrate. Surface profiling and optical microscopy were applied fur surface analysis to understand the progression of surface modification during chemical preparation process. Groan copyright
