cure through additional cured resin on the backside of the slice in the z axis how to identify cure through can be diagnosed as follows holes or small features resolved too small and oblong in shape text is distorted engraved text appears to have reduced height embossed text appears to have an upwards shadow print artifact 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 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 if possible for your material specifications, switch to a darker colored resin resin 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 orientation reorient the part to place holes in the xy plane orientation supports use scale to bring part features into your specification range by adjusting the z scale factor automatic scale factors account for inaccuracies in the majority of cases, but tweaking the scale factor further may help dial in your feature sizes in some cases design use dls design gudielines for holes in the z axis to bring part features into your specification range reference the tips for optical effects in dls design guidelines for vertical holes (z) design if problems persist, please reach out to carbon support mailto\ support\@carbon3d com explanation & causes cure through z axis dls design guidelines occurs when light penetrates vertically through a thin area of material and cures resin on the backside of the slice it is essentially overcure in the z axis this phenomenon causes holes to be oblong and 0 050 0 200mm smaller than nominal in the z axis clear or light colored resins experience more cure through as light penetrates through these materials more easily the printer software applies a cure through correction to your slices, but some amount of cure through may still occur cure through z axis 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 oriented holes in the z axis are oblong additional resin cures along the window facing side of the hole designed holes in the z axis are too small too much light is shining through slices that define the hole 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 color features are too small clear or light colored resins experience more cure through as light penetrates through these materials more easily
