Abstract：Toaddressthe issue thatthecasting mold foracertaincommercialvehiclecrossbeam hasahigh cost proportionand along manufacturing cycle under thescenariosof itslarge overall dimensionsandsmall-batch trial production，thisstudyaims torealize the mold-free，low-cost，andhigh-eficiency manufacturing of thecrossbeam. Taking theaforementioned commercialvehiclecrossbeamastheresearch carier，thisstudyexplores thedigitalmodel processing，additive strategy，prototypeprinting，staticperformance，andeconomiceficiencyinthefabricationof large sized automotive components via arc additive manufacturing.
