چکیده

در این مقاله الگوی نوینی برای ساخت داربست‌های مهندسی بافت، با استفاده از روش پرینت سه‌بعدی ارائه شده است. جهت ساخت داربست‌ها از رزین آکریلاتی حساس به نور استفاده شده است. نمونه‌های نهایی دارای دو ساختار ساده و گرادیانی می‌باشند که رفتار مکانیکی آن‌ها مورد بررسی قرار گرفته است. خواص مکانیکی نمونه‌ها با استفاده از تست فشار تک‌محوره و معادله تجربی مورد بررسی شد. نتایج نشان می‌دهد که تحت تغییر شکل‌های بزرگ در نمونه‌ گرادیانی برخلاف نمونه ساده نواحی الاستیک متعددی بوجود می‌آید. استفاده از این نوع لایه‌بندی در کنار مزیت زیستی نمونه گرادیانی می‌تواند کارایی داربست-ها را بهبود بخشد.
