“…A computer can then reduce the model to slices or layers. The 3D objects are constructed layer-by-layer using rapid prototyping techniques such as fused deposition modeling [165,166], selective laser sintering [167][168][169], laser cladding [170], 3D printing [171][172][173][174][175][176][177][178][179][180], solid freeform fabrication [181][182][183][184][185] and/or stereo lithography [186][187][188][189]. Furthermore, a thermal printing process of melted calcium orthophosphates has been proposed as well [190].…”

In the late 1960's, a strong interest was raised in biomedical applications of ceramic materials (named bioceramics a little bit later). Bioceramics was initially used as reasonable alternatives to metals in order to increase their biocompatibility. However, within a short period, it has grown into a diverse class of biomaterials, presently including three essential types: relatively bioinert, bioactive (or surface reactive) and bioresorbable bioceramics. This review is limited to bioceramics prepared from calcium orthophosphates only, which belong to the categories of bioactive and bioresorbable compounds. There have been a number of important advances in this field during the past 30 -40 years. The research was shifted from an initial study on the develop-ment of bioinert bioceramics towards bioactive and bioresorbable bioceramics, and these different types of calcium orthophosphate bioceramics can be tuned through the structural and compositional control. At the turn of the millennium, a new concept of calcium orthophosphate bioceramics has been developed to promote a regeneration of bones. Current biomedical applications of calcium orthophosphate bioceramics include artificial replacements for hips, knees, teeth, tendons and ligaments, as well as repair for periodontal disease, maxillofacial reconstruction, augmenttation and stabilization of the jawbone, spinal fusion and bone fillers after tumor surgery. Potential future applications of calcium orthophosphate bioceramics are demonstrated in drug delivery systems, effective carriers of growth factors, bioactive peptides and/or various types of cells for tissue engineering purposes.

“…Consequently, pure titanium, Ti-6Al-4V and NiTi shape memory alloy, which are known for their biocompatibility and good corrosion resistance, have been successfully sintered into 3D porous structures for medical implantation using Nd:YAG laser [47,48]. Bioceramics such as hydroxyapatite (HA) could also be sintered to form customized implants for bone substitution [49]. The type of laser used in SLS can affect the properties (mechanical properties, density, and surface texture) of SLSformed objects.…”

Selective laser sintering (SLS), a mature and versatile rapid prototyping (RP) technology, uses a laser beam to selectively sinter powdered materials to form three-dimensional objects, porous or non-porous, according to the computer-aided design which can be based on data obtained from advanced medical imaging technologies such as magnetic resonance imaging (MRI) and computer tomography (CT). In this chapter, major RP technologies suitable for biomedical applications are briefly introduced first. A review is made on SLS, including its working principle, modification of commercial SLS machines for fabricating biomedical products, biomedical SLS materials, and optimization of SLS parameters. Finally, a detailed presentation is given on the biomedical application of SLS, focusing on the fabrication of tissue engineering scaffolds and drug or biomolecule delivery vehicles. It is shown that SLS has great potential for many biomimetic and biomedical applications.

Tetracalcium phosphate (TTCP, Ca 4 (PO 4 ) 2 O) was functionalized by poly (l-lactic acid) (PLLA) in order to improve the dispersion of TTCP particles in poly (butylene succinate) (PBS) matrices, and then a series of the PLLA grafted TTCP/PBS (g-TTCP/PBS) composites were prepared via melt processing. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), tensile analysis, differential scanning calorimetry (DSC), thermogravimetric analysis (DTG/TGA) and melt rheological analysis were used to investigate the structure and properties of the g-TTCP/PBS composites. The results revealed that l-lactide could be grafted onto the surface of TTCP, and the g-TTCP/PBS composites showed the best mechanical properties when the content of g-TTCP was 10 wt%. The crystallization temperature of g-TTCP/PBS composites tended to increase with the increase of g-TTCP contents. The functionalized particles played an important role in augmenting the thermal degradation rate and the complex viscosity of the composites due to their unique structure and the reasonable interfacial interaction between the particles and PBS matrix.
