摘要：Polycaprolactone-carboxymethyl cellulose composites have been obtained and used to print porous structures by material *** materials used contained 0,2 and 5% w/w of the carboxymethyl cellulose *** structures have been analyzed in terms of their morphology (including the evaluation of their porosity),mechanical properties under compression load and cell *** affinity has been evaluated by culturing sheep mesenchymal stem cells and analyzing their viability by the Alamar Blue(R)assay at days 1,3,6 and *** results show that composites samples have similar values of porosity and apparent density than pure polycaprolactone ***,samples containing 5%w/w of carboxymethyl cellulose have micropores on the filaments due to a hindered deposition *** characteristic affects the mechanical properties of the structures,so these ones have a mean compression modulus significantly lower than pure polycaprolactone ***, the samples containing 2%w/w of carboxymethyl cellulose show no significant difference with the pure polycaprolactone ones in terms of their mechanical ***,the presence of 2%w/w of additive improves cell proliferation on the surface of the porous *** complementary information,the flow properties of the composite materials were studied and the power law equations at 210℃ obtained,as this temperature was the 3D printing *** equations can be useful for simulation and designing purposes of other manufacturing processes.
