Application experience and research progress of different emerging technologies in plastic surgery

Table 1 Various three-dimensional printed bioplastics and their properties

Category	Characteristics
PLA	It comes in a variety of translucent colors and glossy textures. As an environmentally friendly plastic, it can biodegrade into active compost. Derived from renewable resources - corn starch and sugar cane. 3D technology is used to form biodegradable polymer materials that can produce tissue engineering scaffolds with high porosity and the ability to grow
PETG	Short thermoforming cycle time, low temperature and high yield. Low shrinkage and good hydrophobicity of the material, thus eliminating the need for storage in confined spaces
PHB	Low melting point biodegradable polyester. As with most biomaterials, it is often used as sutures and has shape memory. Due to the low melting point, high printing temperatures are not required, thus saving energy

PLA: Polylactic acid; PETG: Polyethylene terephthalate-1,4-cyclohexanedimethanol ester; PHB: Polyhydroxybutyrate; 3D: Three-dimensional.
