“…Such a high level of process flexibility enable it can directly fabricate complex internal structures and customized shapes. Up to now, AM has been applied to prepare bone scaffolds from various materials, including metals [12][13][14], polymers [15][16][17] and ceramics [18][19][20], even their composites [21][22][23]. Among them, metal bone scaffolds are most promising for load-bearing bone repair [24].…”

Iron metal possesses good biocompatibility and excellent mechanical strength, though it degrades too slowly. In this work, selective laser melting (SLM) was applied to fabricate iron-manganese (Fe-Mn) biodegradable scaffold. Results shown Fe-Mn scaffold exhibited a uniform pore structure with a porosity of 66.72±2.3%, which highly matched with as-designed model. Phase analysis revealed Fe-Mn scaffold mainly contained α-Fe, martensitic and austenitic phases. Due to the potential difference among these different phases, galvanic corrosion occurred in Fe matrix. In addition, a small amount of Mn distributed at grain boundaries also contributed to the formation of galvanic corrosion. Thus, the corrosion rate increased from 0.09±0.02 mm/year to 0.23±0.05 mm/year. The scaffold exhibited suitable mechanical properties with a yield strength of 137±8.4 MPa, an ultimate strength of 221.7±10.9 MPa. Moreover, cell assays demonstrated its good cytocompatibility. Taking these positive results into consideration, SLM processed Fe-Mn scaffold was a promising material for bone repair application.

“…For the preparation of metal oxides, several warning is need to unused in rectors' receptacle such as platinum, silica and alumina. Traditionally, a rise -temperature ceramic synthesis, also denoted as ceramic route or bake and shake, is used to fabricate inorganic nanostructures [124][125] . According to process, the materials precursor have intimately been grounded in equipollent amounts and heated at high temperatures for long time to facilitate inter prevalence of the reactant reagents.…”

The chemical procurer is an exciting phenomenon, which involves pervasion of various reactions on dissimilar media. The synthesis practicability lets the assortment of materials nanoscale, including oxides, minerals, alloys, and sulfides...etc. Research on inorganic materials will fetch ameliorations to innovative techniques, such as the nanostructure, morphology associated technique and description conjugation artistry. To obtain optimized synthesis performance with the inorganic nanostructures, however, numerous challenges as yet stay. More research and additional effort is needed to address the following important issues to enhance the practical preparations of nanostructures for inorganic compounds. This paper provides an inclusive review of recent and current researches that focus on the general technical method ways for synthesizing inorganic materials in different nanoscales. The chemical growth of particles in a nanoscale can be quite different from those of large quantities of substances or atoms and the individual molecules that make up them. Obviously, there are continued efforts by a large group of chemists to prepare inorganic nanomaterials, and behaviors both known and desirable for chemicals are worth and choose the appropriate methods. In addition, in this paper, it can open the way to illustrate the choice of the appropriate method for many researches.

“…As acrylate monomers, polyethylene glycol diacrylate (PEGDA) [ 31 , 32 ], 1,6-hexanediol diacrylate (HDDA) [ 33 , 34 ], and bisphenol A ethoxylate diacrylate (BEDA) [ 35 , 36 ] were employed; as a photoinitiator, a phosphine oxide-based compound (BAPO) was selected. This photoinitiator is widely employed in SL or DLP 3D printing [ 37 , 38 , 39 ] but it is not considered biocompatible, unlike other photoinitiators such as Lithium phenyl–2,4,6–trimethylbenzoylphosphinate (LAP). However BAPO is 20 times cheaper than LAP and it was demonstrated that it may show low toxicity effects on cells if added in the adequate concentrations [ 30 , 40 , 41 ].…”

Light-based 3D printing techniques could be a valuable instrument in the development of customized and affordable biomedical devices, basically for high precision and high flexibility in terms of materials of these technologies. However, more studies related to the biocompatibility of the printed objects are required to expand the use of these techniques in the health sector. In this work, 3D printed polymeric parts are produced in lab conditions using a commercial Digital Light Processing (DLP) 3D printer and then successfully tested to fabricate components suitable for biological studies. For this purpose, different 3D printable formulations based on commercially available resins are compared. The biocompatibility of the 3D printed objects toward A549 cell line is investigated by adjusting the composition of the resins and optimizing post-printing protocols; those include washing in common solvents and UV post-curing treatments for removing unreacted and cytotoxic products. It is noteworthy that not only the selection of suitable materials but also the development of an adequate post-printing protocol is necessary for the development of biocompatible devices.
