It was found that the obtaining of quality 3D printing filaments, without defects and natural color, from corn starch physical modified with PVOH, depends also on the melting behavior at compounding, both of starch and of PVOH, and on the controlling of the process sensitivity of the new compounds. A comparable melting behavior was possible by compounding the two polymers as powders with similar small sized particle. The controlling of the process sensitivity was achievable, mainly, by diminishing the melt resistance to flow, via formulation with a flow agent. The selected compounds which had controlled miscibility, few defects and natural color were shaped, with good results, as filaments with silky and smooth surface. These filaments were compatible with 3D printing because proved to have the ovality and the diameter tolerance in the accepted limits in the fields.

“…The two polymers, with proper melt processing additives and the entanglement compatibilizer was compounded in a Brabender plasticorder. Each blend was molded into films with 0, 01 mm thickness on a classical laboratory roller [1,13]. Bio-hibrids with 3 % treated silicate and blends based on PVOH and starch were studied.…”

Based on the FTIR spectral changes, the miscibility of some nanocomposites based on starch, polyvinyl alcohol and treated multilayered silicate, was qualitatively estimated. The FTIR spectroscopy provide evident gross/small spectral changes as well as appreciable spectral shifts mainly in those spectral range that defines hydroxyl O-H vibrations (3600-3000 cm -1 ), water absorbtion (1800 -1500 cm -1 ) , the morphological order degree and the interaction with multilayered silicate and (1192 -950 cm -1 ). Based on the observed spectral modifications it can be estimate that high miscibility do exist between the components of the studied nanocomposites.

“…This results in a melting temperature of approximately 230 °C, close to the decomposition temperature (230–250 °C). As a result, PVA is difficult to process through melting [ 49 , 50 ]. On the other hand, PC has the advantages of ABS, as well as good flame retardancy, low shrinkage, and high mechanical strength [ 51 ], and does not emit toxic or unpleasant gases during printing [ 47 ].…”

The application of polymer materials in sculpture art creation is extensive and plays a significant role in the development of sculpture art. This article aims to systematically explore the application of polymer materials in contemporary sculpture art creation. The research comprehensively applies various techniques such as literature research, data comparison, and case analysis to explore in detail the ways, methods, and paths of polymer materials employed in the shaping, decoration, and protection of sculptural artworks. First, the article analyzes three methods of shaping sculpture artworks with polymer materials (casting, printing, and constructing). Secondly, it explores two techniques of using polymer materials to adorn sculpture artworks (coloring and imitating texture); then it discusses the significant approach of using polymer materials to protect sculptural artworks (protective spray film). Finally, the research identifies the merits and demerits of using polymer materials in contemporary sculpture art creation. The findings of this study are expected to enrich the effective application of polymer materials in contemporary sculpture art creation and offer novel techniques and ideas for contemporary sculpture art creators.
