Generally acknowledged material, chemical, mechanical, and structural requirements of scaffolds have placed strict pre-requisites and challenges on the fabrication technologies.
When developing the scaffolds, it is important to take into consideration the requirements of scaffolds as well as the drawbacks of the materials being used, so that the researcher can then test accordingly.
The blended polymeric materials were developed from commercially available, inexpensive and well characterised biodegradable polymers, which on their own lacked both the structural requirements of a scaffold material and, critically, the ability to facilitate cell growth.
This work suggests an effective, biomimetic approach for balancing strength and bioactivity requirements of porous scaffolds for tissue engineering.
Resulting macro-porous structures were also studied to evaluate the potential of 3DP technology for meeting the small-scale geometric requirements of bone scaffolds.
The biomechanical processes of bone regeneration are complex, so the requirements for scaffold design are diverse [ 12, 62– 62].
Electrospinning technique can be used to produce the three-dimensional nanofibrous scaffold similar to natural extracellular matrix, which satisfies particular requirements of tissue engineering scaffold.
However, further studies are needed to obtain a biomaterial that fulfills all the requirements of an ideal scaffold in terms of biocompatibility, bioactivity, and biodegradability, and able to give an optimal outcome at long-term follow-up.
To achieve such a hierarchical porous structure with accurately controlled internal pore architectures, the recursive intersection Boolean operation (RIBO) was proposed in order to satisfy computational efficiency and biological function requirements of a porous scaffold.
