This is resin made for the Wanhao Duplicator 7. Resin4Decor Low Viscosity Clear Resin (12h Curing Time). Wanhao 3D-Printer UV Resin - 500 ml - GreenWanhao UV Resin for DLP / SLA / LCD 3D-Printers Wavelength 405NM Time for solidify 8 - 16s Viscosity (25 degree) 120~140 mPa. However, curing time did not affect the SBS significantly in the 2 mm thickness groups. Digital light processing (DLP) 3D printing is a technology which uses a UV light to shine through an LED screen, curing resin layer by layer with extreme precision. The Wanhao Duplicator 7 is a resin desktop 3D printer. the resin component of the adhesive to migrate along the substrate surface. - plug off the cable cord when not used for a long period of time. 5 seconds curing time. Cumene Hydroperoxides (CHP) achieve cure using lower exotherm temperatures which reduces resin shrinkage. The Duplicator 7 Plus has a build area of 120x70x200mm and a layer resolution capability of 35 microns. molecular weight approaches infinity.
