Industrialization of Selective Laser Melting for the

Since porous pure titanium implants showed very similar mechanical behavior, this could potentially lead to a revival of the use of pure titanium for dynamically loaded porous implants. But in the end, the manufacturing cost is also important for the acceptance of this new technology to produce porous metallic implants on a commercially suitable level. Get price
