PA12 SLS Laser Parameter Matching
ظاهرة المشكلة
【Problem phenomenon】SLS printed PA12 parts had insufficient strength or surface overburning, and laser parameters attended to one thing and lost another
تحليل الأسباب
Laser power 150-200W, scanning speed 500-800mm/s, and layer thickness 0.1-0.15mm are the common windows for PA12; insufficient power causes incomplete sintering and low strength, too high causes overburning degradation and poor surface
الحل
Start optimization from 150-200W power, 500-800mm/s speed, and 0.1-0.15mm layer thickness; for reinforced powder, increase power by 10-15% and reduce speed by 5-10%; comprehensively evaluate energy density
الخلاصة الأساسية
SLS laser parameters depend on the comprehensive value of energy density, and raising power alone easily causes overburning; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
