Preparation of PLA/PEG Composite Filaments and Their 3D Printing
The polylactic acid/polyethylene glycol (PLA/PEG) composite filaments and its 3D-printed samples were successfully prepared,then the mechanics performance,thermal performance and biomedical application of the PLA/PEG composites were investigated.The results show that the addition of PEG improves the mechanical properties of PLA material,but reduces the glass transition temperature and cold crystallization temperature.Furthermore,the SEM shows that the 3D-printed biomedical objects possess high printing precision.The successful preparation of PLA/PEG composites for 3D printing can further explore its application in medicine and biology fields.
