“…From the DSC results, Table 3, filament and scaffold showed similar T m and T g values, suggesting no molecular interactions during 3D printing processing [13] . An increase from 7.1 to 11.6% in crystallinity was observed, indicating favored crystallinity in 3DP [29] , as observed in extrusion. Composites of PLA and tricalcium phosphate processed by extrusion [39] with a similar behavior presented adequate mechanical properties for scaffolds.…”

“…Os espectros de FTIR do PET, EGMA e das blendas PET/EGMA são ilustrados na Figura 4. Observa-se a existência de bandas típicas presentes na cadeia do PET, situadas em 1000 e 800 cm -1 , que representam a vibração de deformação do grupo éster (-COO-) [23]. No espectro do EGMA, verifica-se a presença do anel epóxi presente nos grupos metacrilato de glicidila (GMA) caracterizada pela existência de uma banda localizada entre 908-912 cm -1 , correspondente à contração das ligações C-C, e estiramento das ligações C-O [7,17].…”

“…Estes resultados estão em consonância com Silveira [23], Baouz et al [24] e Feng [25] quando eles estudaram o efeito de copolímeros contendo -GMA numa blenda com poliácido láctico (PLA) como matriz. Analogamente Brito et al [22,26] observaram melhora significativa na resistência ao impacto de blendas de PLA/ EMAGMA.…”
