Scaffolds are a promising innovation that create a suitable environment for the restoration of tissues.  They can also be used to achieve efficient drug delivery to specific sites.  Poly(butylene succinate) (PBS) is a biocompatible and biodegradable polymer that has been utilized in various research fields.  Fused deposition modeling (FDM) was conducted to construct PBS scaffolds with two specific lay-down patterns: grid and triangle.  The salt leaching technique was also used to produce pores in the scaffolds.  A morphological study, porosity measurement, and contact angle analysis were carried out to characterize scaffold morphology, pore characteristics and surface properties.  Salt content and type of lay-down patterns were found to affect the porosity and wettability of the scaffolds.  Porosity increased with an increasing proportion of salt while scaffolds with a triangle pattern were more porous than grid pattern at the same salt content.  The wettability test showed that the contact angle of all scaffolds ranged between 88° and 102°, while the grid pattern was more hydrophobic than the triangle pattern.
