The need of solvent can be circumvented using photocurable bottlebrush polymer melts as inks, which can be solidified by UV after deposition . However, the materials design requires sophisticated chemistry, and the printed parts are not reprocessable. Additionally, the photocrosslinking process is sensitive to the intensity of light, which inevitably diminishes as the size of printed objects increases. This may result in uncontrollable crosslinking and mechanical properties.
