        • Viscosity at 25ºC:  19.000-21.000 cps: printable
        • Viscosity at 30ºC: 15.000-16.000 cps: printable 
        • Viscosity at 40ºC: 5.500-6.500 cps: printable

      IFU for 100% clarity & transparency (without any haziness or whitish finishing)

      • print aligners in any SLA, DLP and/or LCD printer following our printing instructions, which can be sent upon request by email: info@3dresyns.com 
      • after printing cut the supports and eliminate the uncured resin by gravity from the surface of the aligner in the upside down position in an oven heated at 55-60ºC for 30 minutes
      • postcure the dry prints in a normal light box for 30 minutes at T<50ºC
      • clean parts by spraying IPA using a spray bottle to ensure that clean IPA is always used

      Examples of aligners software which can be used: Archform, BlueSkyBio, etc

           

          *Note: direct printing of aligners requires detailed integration of aligners specifications and control of the overall workflow and process variables (software, aligner thickness, resin design, printer specifications such as power, wavelength, print settings: exposure time, z layer thickness, postcuring and cleansing settings and protocols, types of cleaning fluids used, cleaning time and temperature, light power, wavelength and temperature during postcuring, etc.

          All the mentioned variables affect and determine final aligner mechanical properties, clarity and biocompatibility: such as  its hardness, rigidity, stress relaxation resistance during usage, color, overall resistance, durabibility and safety.

          Different printers, printing settings and specifications, cleaning and postcuring settings, etc in practice provide differences in properties for any 3D photoreactive resin
