Abstract
Nanomodified polyetherimide samples obtained by fused deposition modeling using an experimental setup for three-dimensional printing of highly heat-resistant plastics are studied. Their structure and thermal properties are investigated by pycnometry, scanning electron microscopy, differential scanning calorimetry, thermogravimetry, and dilatometry. It is found that the modification of polyetherimide with carbon nanofibers considerably reduces the porosity of printed samples. An analysis of cytotoxicity shows that the tested materials are bioinert.
