However, the powder bed fusion technique still faces two major challenges: it is high cost and time-consuming. Additive manufacturing through powder bed fusion shows great potential for the fabrication of high-quality porous metal implants. Several types of additive manufacturing techniques including selective laser sintering, selective laser melting, and electron beam melting, are discussed for different applications.

You enter and exit math mode by using the dollar-sign. This review explores open-cellular structural design for porous metal implant applications, in relation to the mechanical properties, biocompatibility, and biodegradability. The space after the command will not create a space in your document, but it is necessary for. Additive manufacturing technology allows the production of complex structures with bio-mimicry features, and has the potential to overcome the limitations of conventional fabrication methods. The, in the integrals makes a small space before the dx. Actually i want to concat variable if u notice my question my var with the name of three one.

Recently, the fabrication methods of orthopedic implants and devices have been greatly developed. Use displayed math mode instead and youll get a larger integral symbol: Code: texint dx.
