Scratches and Scuffs

scratches and scuffs a line or scuff mark in the part that occurs after printing scratch example how to identify scratches and scuffs can be diagnosed as follows a recessed line in the part that was not there immediately after printing but appeared sometime during post processing a line or scuff that is lighter in color than the rest of the part material appears scuffed and scraped across the surface this can occur with resins that are softer in the green state https //res cloudinary com/carbon3d/image/upload/v1741915985/education/troubleshooting/part defects/scratches scuffs/scratch 01 png inconclusive https //res cloudinary com/carbon3d/image/upload/v1741915983/education/troubleshooting/part defects/scratches scuffs/scratch 02 png inconclusive https //res cloudinary com/carbon3d/image/upload/v1741915979/education/troubleshooting/part defects/scratches scuffs/scratch 03 png inconclusive https //res cloudinary com/carbon3d/image/upload/v1741915981/education/troubleshooting/part defects/scratches scuffs/scuff 01 png inconclusive https //res cloudinary com/carbon3d/image/upload/v1741915987/education/troubleshooting/part defects/scratches scuffs/scuff 02 png inconclusive https //res cloudinary com/carbon3d/image/upload/v1741915989/education/troubleshooting/part defects/scratches scuffs/scuff 03 png inconclusive https //res cloudinary com/carbon3d/image/upload/v1741915982/education/troubleshooting/part defects/scratches scuffs/scuff 04 png inconclusive https //res cloudinary com/carbon3d/image/upload/v1741915991/education/troubleshooting/part defects/scratches scuffs/scuff 05 png inconclusive 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 process if any of these conditions apply to your print, take the corrective action and reprint to see if the problem is resolved post processing handle parts in the green state with care parts held on the faces instead of edges can show smudges from gloves handle parts with caution during washing avoid over packing parts if you are washing them off the platform begin with light pressure in the compressed air cabinet and increase pressure intensity gradually use recommended rpms on the orbital shaker, increasing gradually if parts are not losing adhesion to the platform use all tools with caution near the parts if problems persist, please reach out to mailto\ support\@carbon3d com explanation & causes explanation parts are more fragile in their green state and can pick up damage during processing parts bump into one another during washing (when washed off platform) parts are blown off the platform in the compressed air cabinet a tool or baking implement scrapes the part parts held on the faces instead of edges can show smudges from gloves hold parts on edges instead of faces causes post processing how the part is handled in post processing is causing the defect post processing root issue problem why defect presents reckless handling parts are blown off the platform in the compressed air cabinet parts blown off the platform can run into items that can cause scratches, such as the platform or the air gun a tool or baking implement scrapes the part tools scraping across green state parts can leave permanent marks parts held on the faces instead of edges can show smudges from gloves minor amounts of residual resin on the surface can appear different when held tightly with a gloved hand washing setup parts bump into one another during washing (when washed off platform) some resins are softer in the green state, so when parts bump into each other in this state, the can leave permanent scratches
