Stereolithography technique is dealt with the techniques of machinery, laser, numeral control, computer software and photosensitive resins, etc. The quality of the photosensitive resins has direct effect on the dimensional accuracy, mechanical properties of the fabricated parts. Therefore the further research on SL7560 type photosensitive resins is very meaningful and valuable. The properties of SL7560 type photosensitive resin were investigated by some instruments and equipments. Characteristics of FT-IR showed that SL7560 type photosensitive resin belonged to an epoxy-acrylic hybrid photosensitive resin. The experimental results showed that its viscosity at 30°C was 197mPa.s, its critical exposure (Ec) was 5.9mJ/cm2, its penetration depth (Dp) was 0.14mm, the tensile strength of its cured product was 43.7MPa, the tensile modulus was 2549MPa, the elongation at break was 10.7%. With the photosensitive resin as the processing material, the part of a mobile phone shell was fabricated using the Stereolithography Apparatus (HRPL-I), and the quality of the fabricated part was good.
