Flashing

flashing additional cured resin at the base of the part how to identify flashing can be diagnosed as follows at the base of the part, with the base being the surface that was on the platform during printing extra cured resin appears along the part's base edges docid\ up tsq77razxlvuevcvmq is a defect that may appear similar at the part's base but will be jagged instead of smooth the base appears larger than the rest of the model labels on the base of the part are difficult to read or unreadable cause inconclusive cause inconclusive cause inconclusive cause inconclusive unreadable label cause inconclusive unreadable label troubleshooting it is recommended that you review all the possible solutions before taking action to ensure you are pursuing the best course of action if the best course of action is not apparent, try the troubleshooting options in the order listed refer docid\ ppm8gmegcy 0fkfwgtcyj for more tips hardware checks if any of these conditions apply to your print, take the corrective action and reprint to see if the problem is resolved hardware verify platform and cassette are installed properly m1/m2 printers clean the platform's kinematic balls and clean & lubricate the kinematic pin mounts on the platform and cassette per docid 0ywe7ymsiydn imldvtpn do not do not bake parts on the platform which will cause misalignment of the kinematic balls reference cleaning and installation instructions for your printer docid 6pwz7jx jb4l5 xwkoj , docid 3yymggihdvaowg01eay6l , docid\ on8otjugbxoth6qmqw2om hardware diagnostics the following diagnostics may help determine if the issue is hardware related hardware print with a different platform and/or cassette if the issue is resolved with another platform or cassette, reach out to mailto\ support\@carbon3d com for assistance with the problematic hardware run an docid\ eneydjvgk9i1zhog5jjje print preparation or part design adjustments choose among the suggested actions below and select the best approach for your application print plan adjustments reference docid\ nxuk0dltz vemeau0dipn for guidance on the following parameters docid\ nunxrrm4bwbawuqk0frdt exposure timing parameters base exposure multiplier brightlining parameters all four parameters must be specified brightline interior exposure time brightline exterior exposure time brightline border thickness pixels brightline outer borders if problems persist, please reach out to mailto\ support\@carbon3d com explanation & causes explanation flashing is additional cured resin at the base of the part this is due to light scattering as a result of the docid\ t94pr a c0pihy6ljswk7 overcure can occur throughout the part (2) (2) , but flashing is a specific case at the base of the part due to the higher exposure times needed for adhesion to the platform (1) (1) base adhesion generally requires exposure times 5 20 times higher than the nominal exposure throughout the rest of the print to avoid adhesion failures the extra exposure time, however, can cause significant overcure as photons scatter overcure causes hardware the printer, cassette, or platform is dirty or requires maintenance to resolve the defect occasionally, a defect may indicate the printer requires servicing by a carbon engineer root issue problem why defect presents misalignment improper seating the platform could be too close to the window, receiving a higher dose of uv light than intended misalignment unlubricated kinematic pin mounts m1/m2 printers only the platform could be too close to the window, receiving a higher dose of uv light than intended misalignment mechanical alignment of the printer the platform could be too close to the window, receiving a higher dose of uv light than intended print plan adjustments print plan adjustments docid\ nxuk0dltz vemeau0dipn adjust the print plan to optimize mid to high volume production and/or address part defects in doing so, adjustment may both prevent or cause defects below are adjustments that can cause this defect printing stage parameter type type of adjustment why defect presents 5 exposure exposure timing increase increase more uv exposure at the base increases overcure that causes flashing 5 exposure brightlining increase increase more uv exposure at the base increases overcure that causes flashing
