Caping

caping capes or sheets of resin form on and between parts/features how to identify caping can be diagnosed as follows irregularly shaped strands/sheets of cured resin on the exterior of and between parts on the build this is an uncommon defect this is an extreme form of docid\ jjgvksg a4hng6atn iy2 cause layout layout solution print preparation or part design 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 docid\ ppm8gmegcy 0fkfwgtcyj for more tips process, material, and hardware checks if any of these conditions apply to your print, take the corrective action and reprint to see if the problem is resolved resin selection double check that the resin selected in the ui for the build was the same resin printed resin selection resin handling after printing m1, m2, or l1 printers check window between prints for debris reference docid\ kqygmwdx 5lnp uy81 xt for more information 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 docid 6pwz7jx jb4l5 xwkoj , docid 3yymggihdvaowg01eay6l , docid\ on8otjugbxoth6qmqw2om hardware 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 docid\ y imi7aevlyjbsatexxdb for more information print with a different cassette if the issue is resolved with another cassette, reach out to mailto\ support\@carbon3d com for assistance with the problematic hardware print preparation or part design adjustments the following solutions will address print or part related causes of the defects choose among the suggested actions below and select the best approach for your application usually only one type of adjustment is needed supports adjust supports to allow more space between part and support adjust density of supports to allow for more resin flow supports layout increase padding to at least 5 mm reference docid\ sj39gtbagt0csgvvlcfli layout print profile small unvented volumes available in software docid\ m57iwuleuclygcsbkfe62 and higher for use with prints where there is distortion or extra cured resin on the surface of critical features inside holes most commonly seen in analog or anterior die holes in dpr 10 , but applicable to any application with similarly fitting parts like connectors may also help with docid 3eiqqqqcgkwu6qngdr5ox in parts with large window facing cross sections default print using the default print profile instead of dynamic to slow down the print reference docid\ n9rcre4j391hmxwvp udg dynamic is a tool for m1 and m2 printers force feedback (ffb) printers (m3, m3 max, l1) will see minimal to no difference in print speed with the dynamic print profile, so this troubleshooting option is unlikely to help default print profile print plan adjustments reference docid\ nxuk0dltz vemeau0dipn for guidance on the following parameters docid\ nnb8zuqlpvprucppbwwsr delay timing parameters minimum pre exposure delay minimum time force slope down settled if problems persist, please reach out to mailto\ support\@carbon3d com explanation & causes explanation stray uv light partially cures a film of resin close to the window that film eventually attaches to the part and is pulled up as the part builds the build is not receiving the proper dosage of light and/or oxygen overheated resin disrupting the normal pigment concentration and disbursement causes print preparation or part design how the part is oriented , supported , or designed is causing the defect print preparation or part design cause root issue problem why defect presents supports over supported parts that are over supported provide less space for resin to flow properly throughout the build causing light to scatter layout parts too dense on platform padding between parts is to small for resin to flow properly throughout the build causing light to scatter print profile print too fast in dynamic a shortened print gives less time for resin flow to all areas of the build causing light to scatter for m1 and m2 printers 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 cleaning cassette window is dirty a dirty or faulty cassette inhibiting regular light and oxygen flow deck glass is dirty (m1/m2) projector lens is dirty (m3/m3 max/l1) window damage a dirty or faulty cassette inhibiting regular light and oxygen flow resin the printing material is expired , beyond the printing range in its pot life , or has been improperly mixed , causing abnormalities in the print resin root issue problem why defect presents resin selection wrong resin the print is not receiving the proper dosage of resin resin handling after printing not checking window between prints not checking the window between prints could leave accidental debris behind for the next print that inhibits proper uv exposure additionally, checking the window helps cool down the resin between prints overly heated resin can disrupt normal pigment disbursement 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 4 settle down delay timing decrease decrease the settle down phase is too fast for proper resin flow and oxygen recharge, build causing light to scatter
