聚（3-羟基丁酸酯）（PHB）3D多孔立方体成功地使用选择性激光烧结（SLS）构建，这是许多现有3D打印技术之一。由此产生的立方体呈现出与相应的虚拟模型非常接近的形状和尺寸。此外，它们不易搬运，没有任何可见的损坏。如通过质子核共振（H-1 NMR）和差示扫描量热法（DSC）分析所观察到的，在SLS过程32.15小时之后，PHB粉末没有呈现热性质和化学组成的变化，这表明它可以被重新利用以打印另外的结构而不影响过程的再现性。
Poly(3-hydroxybutyrate) (PHB) 3D porous cubes were successfully built with Selective Laser Sintering (SLS), one of the many existing 3D printing technologies. The resulting cubes presented shape and dimensions very close to the corresponding virtual model. Moreover, they were resistant to handling without presenting any visible damage. The PHB powder did not present variation in thermal properties and chemical composition after 32.15 hours of SLS process as observed by proton nuclear resonance (H-1 NMR) and differential scanning calorimetry (DSC) analysis, indicating that it can be re-utilized to print additional structures without affecting the reproducibility of the process.
