Zti powder deployed on dmt insstek technology

Development of dmt 3d printing process technology for new metal matrix composite material (zti-powder)

- Metal 3D printing technology is a topic of increasing global interest and receives a great deal of attention as the main production technology of Industry. In particular, the DED (Directed Energy Deposition) method of metal 3D printing shows several advantages over the PBF (Powder Bed Fusion) technique such as the size distribution and variety of used powders, simple fabrication of products, repair and remodeling of damaged machine parts/products. Furthermore, various materials can be applied to the same parts/products, while there is essentially no limit for the size of the product and the physical and mechanical properties of the printed part/product is superior. Ti-6Al-4V is a titanium alloy which is used in aerospace, transportation and medical fields, has various and excellent properties but is vulnerable to abrasion and corrosion. On the countrary, Ceramic are attracting attention as cutting-edge medical materials but they are easily broken due to lack of ductility. Recently, Z3DLAB and for the first time in world-wide, has elaborated a new advanced material using the PBF manufacturing technology: (Selective laser melting-SLM with Argon controled enviromenent) by the fusion of two combined powders, Titanium alloy (Ti-6Al-4V) with nanoceramic (Yttria-stabilized Zirconia(YSZ) ) to create a nanocomposite material refered as (ZTi Powder).This Ti-based YSZ composite material also called metal matrix composites (MMC) posses a unique propetiese. it is taugher than Titanium alloys and less britle compared to ceramics which makes it the best candidate for the elaboration of aerospace and transportation parts.Until now, Ti-based YSZ composite materials have been developed using various processes such as Micro-arc oxidation, Brazing with strip NiCrSiB, Sintering by induction, PBF: Spark plasma sintering and hot pressing. However, Tibased YSZ composites for 3D printing such a (ZTi-PowderⓇ) has not been developed to manifacture parts by using the DED (see first paragraph) manufacturing technology. Therefore this (ZTi Powder) is expected to be optimized for 3d printing, the main future production technology of industry and is expected to contribute to various industrial application areas. In Korea, Insstek is the only company that has commercialized DED type 3D printer and processes (DMT refers to Direct Metal Tooling technology) using only domestic technology that produces machine parts and products on demand for domestic/international supply and export. However, the currently developed device does not include a chamber operating under a controlled atmosphere that allows for 3D printing of metal matrix composites such as (ZTi Powder). Thus, 3D printing of such materials faces many restrictions.(ZTi- Powder) material has been fused by SLM technology at Z3DLAB and several mechanical and micrstructura charactirzation were conducted. The founded results were astonishing, but that doesn't mean that the obtained results are going to be the same when the current powder (ZTi Powder) will be fused by the DED tencnology. Therefore, a lot of research work and laboratory experiences such as (Powder folowability, preparation conditions and parts manufacturing parameters...etc) should take place in order to develop the current powder of (ZTi Powder) so the mechanical propoerties obtained by DED would be greater than the PBF elaborated parts in Ti-6Al-4V.
