Detached from Supports

detached from supports a part is partially or completely detached from its supports during printing detached from supports how to identify detached from supports can be diagnosed as follows check the build after printing verify that no parts fell off supports look at parts where they meet the supports and look for areas that are not connected part geometry did not resolve properly cause inconclusive cause inconclusive cause under supported solution print preparation or part design 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 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 change orientations with large suction forces such that supports are carrying a lighter load avoid asymmetric orientations (as in the example below) avoid larger cross sections later in the print obtain a more uniform cross section throughout the print move the part's center of mass closer to the platform orientation supports unvented volume ensure there is enough space between supports for venting break up fence supports into shorter sections with gaps in between to provide venting under supported add more supports for stability reference the orientation & supports for tips on improving stability ensure support parameters are strong enough for the selected resin avoid keeping supports when you change a resin the software will warn you and advise you to clear supports (and re support the part) use the default tip and neck sizes for supports or increase their size when suction forces are especially high reference supports for information on editing support parameters supports print plan adjustments reference print plan adjustments docid\ nxuk0dltz vemeau0dipn for guidance on the following parameters 1 pump up parameters docid\ xp2lrjpj4njfl z8n58rl pump height parameters minimum pump height minimum distance from peak distance from peak multiplier platform speed parameters motor speed u if problems persist, please reach out to carbon support explanation & causes suction forces pulling down on the part are stronger than the provided supports can handle reference dls printer dynamics docid\ u7xyytjydp3bvsyy2qkcu for more information on suction forces m1 and m2 printers generally require more supports than m3 and m3 max printers because they do not have force feedback (ffb) capabilities to respond to suction forces l1 printers fall in the middle because they use ffb but have larger suction forces in general due to large platforms suction forces 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 orientation large cross sections later in the print suction forces increase later in the print from large cross sections and the supports are not strong enough to overcome the force increase orientation asymmetrically oriented part suction forces can cause torque on asymmetrically orientated parts, rotating them off their supports if under supported supports under supported the part simply does not have enough supports to withstand suction forces this is more common with fence supports than bar supports supports supports generated for a different resin supports are resin specific, with default parameters designed for the selected resin if the user opts to keep supports after changing the resin, the supports may no longer be strong enough to hold onto the part supports support tip/neck parameters too small support parameters are editable in carbon software if the supports tips or neck diameter (for bar supports) are decreased from default, supports may no longer be strong enough to hold onto the part unvented volume a vacuum in an unvented cavity exacerbates suction forces print plan adjustments print plan adjustments print plan adjustments 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 1 pump up pump height decrease decrease a shorter pump height can make it more difficult for the part to break free of the dead zone surface tension if this happens, supports may not connect properly to the part 1 pump up platform speed increase increase increased motor up speed increases suction forces
