Vertical Rib

vertical rib raised lines in the part (positive feature) that appear parallel to the z axis (build direction) how to identify vertical rib can be diagnosed as either a long vertical rib on vertical planes a small raised line on curved/sloped surfaces along the build direction (z axis) cause inconclusive cause 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 part defects for more tips try the following actions in order hardware checks diagnostics hardware checks if any of these conditions apply to your print, take the corrective action and reprint to see if the problem is resolved if the defect appears again upon reprint on the same part, in the same location, proceed to diagnostics hardware ensure all of the printer's optics are clean for a clear path for uv light verify the cassette window is cleaned properly, without dust, spots, or streaks verify the projector path is clean m1/m2 printers check the deck glass m3/m3 max/l1 printers check the projector lens reference cleaning instructions for your printer m1/m2 printer docid 6pwz7jx jb4l5 xwkoj m3/m3 max printer docid 3yymggihdvaowg01eay6l l1 printer docid\ on8otjugbxoth6qmqw2om diagnostics if the above checks & actions did not resolve the issue or do not apply to your print, the following diagnostics may further inform what is causing the issue hardware inspect cassette for contamination or damage reference cassette care docid\ y imi7aevlyjbsatexxdb for more information print with a different cassette if the issue is resolved with another cassette, reach out to carbon support mailto\ support\@carbon3d com for assistance with the problematic hardware if problems persist, please reach out to carbon support mailto\ support\@carbon3d com explanation & causes explanation vertical ribs occur when uv light is scattered by an anomaly that cures additional resin in an unintended area this happens in the same place on every layer, which explains why the defect is vertical the uv light can be scattered by a piece of dust or debris a damaged window causes hardware the printer or cassette 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 cleaning cassette window is dirty a dirty or faulty cassette is scattering uv light, causing additional curing at the defect cleaning deck glass is dirty (m1/m2) projector lens is dirty (m3/m3 max/l1) a dirty or faulty cassette is scattering uv light, causing additional curing at the defect window damage a dirty or faulty cassette is scattering uv light, causing additional curing at the defect
