Tears

tears part feature prints properly and breaks at a later point how to identify tears can be diagnosed as follows areas of breakage will fit together like puzzle pieces features will not be missing printed material when the broken area is held back together occurs on elastomeric parts puzzle pieces broken struts docid\ daen8lgs6gp8auw ue5ls and tears docid\ ojz 12lsnz1 5bo4gyw06 are defects that arise from the same issue but one appears on lattices and the other on surfaces, respectively rigid parts experience gouging instead of broken struts or tears cause printing forces printing forces from a layering docid\ f3rkqgeozlwauxwynkdlp defect tearing under forces solution print preparation or part design cause inconclusive cause post processing post processing troubleshooting try the following actions in order process checks print preparation or part design adjustments it is recommended that you review all the possible solutions before taking action to ensure you are pursuing the best course of action process checks most tears occur during post processing review the scenarios below and verify if any apply to operating procedures aggressive part removal follow recommended procedures for washing and proceed gently with elastomeric resins which are delicate in their green state part removal print preparation or part design adjustments it is less common for tears to occur during printing but can occasionally happen due to print forces 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 print plan adjustments reference print plan adjustments docid\ nxuk0dltz vemeau0dipn for guidance on the following parameters 1 pump up parameters docid\ xp2lrjpj4njfl z8n58rl platform speed parameters motor speed up if problems persist, please reach out to carbon support explanation & causes explanation tears can occur in elastomeric parts when they are stretched and pulled to the point of breakage this can occur during post processing or printing, with the former being the common scenario causes post processing how the part is handled in post processing is causing the defect post processing lattice root issue problem why defect presents platform removal aggressive elastomeric resins are delicate in the green state and require gentle handling 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 platform speed increase increase increased motor up speed increases suction forces which can be especially problematic if a large cross section occurs later in the print after delicate struts
