Physical and chemical properties study of 3D printing polyamide by multi-jet fusion and selective laser sintering
摘要
Abstract
Objective To provide a reference for the clinical application of 3D printing guides,the physical and chemical properties of MJF 3D printing polyamide were studied.Methods According to YY/T 1845-2022,the following tests were conducted on MJF 3D printing polyamide specimens:Printing accuracy,material,mechanical,chemical and biological.Results Printing accuracy:Better than SLS 3D printing(0.004 mm vs.0.071 mm).Material properties:VST(175.7℃)met the standard,and load deformation temperature(78.4℃)was slightly below the standard.Mechanical properties:Tensile strength[(42.64±1.83)MPa],elongation[(7.17±0.58)%],flexural strength[(55.64±1.37)MPa],and Rochwell harness[(95.60±3.19)HRR]were not inferior to SLS 3D printing.Chemical properties:Reducing matter(0.4 mL),heavy metals(≤5 μg/mL),pH difference between test and blank control solution(1.22),evaporation residue(1.1 mg),UV-absorption(0.042 5)all met the standard.Biological properties:No significant cytotoxicity,no skin sensitization,no intradermal irritation,no potential pyrogenic reaction,and no acute systemic toxicity.Conclusion MJF 3D printing polyamide material has good printing accuracy,material,mechanical,chemical and biological properties,making it suitable for manufacturing 3D printing guides.关键词
