1.1 Materials and equipments
Huge #46 standard artificial resin tooth (Huge Dental, Shanghai, China), Silastic impression material(3M, Germany), CAD/CAM zirconia ignot, ShoFu veneering powder(ShoFu, Japan), IPS Press Speed Vest embedding material, IPS E.max press MO1 cast ceramic ignot, IPS E.max Ceram Glaze Paste, Zirconia Primer, EP3000 vacuum cast ceramic furnace(Ivoclar Vivadent, Liechtenstein); Adper Easy Self-Etch Adhensive, Unicem-200(3M, Germany), CAD/CAM software(3Shape, Denmark); CAD/CAM glass ceramic ignot, ceramic carving machine(Sirona, Germany); TH-8201S electric universal test machine (Tuobo machinery, China); Light-curing unit(Dentsply, USA); VMS250 3D FAMILY optical image instrument (Zhitai Co.
To consider the reason, firstly, perhaps it is because of the higher flexural strength of the Y-TZP(>900MPa), which is the main material of the whole zirconia crown.

Shrouded turbine blisk often uses difficult-to-cut materials, such as nickel-base superalloy and titanium alloy.
However, it is hard for CNC milling to deal with difficult-to-cut materials, especially for blisk with small channels because of rigidity limit.
EDM is used for machining difficult-to-cut materials [5, 6].

In general, the injection moulding process is not ideal for plastic optical
lenses since excellent replication of the mould contour is very difficult to achieve by using this
process due to free mould shrinkage and stress induced distortion, especially when highly viscous
moulding materials are used.

ZnS is also particularly suitable as host material for a large variety of dopants because of its wide band gap (3.67 eV).
Materials and Methods The synthesis of ZnS:Mn2+ QDs was carried out by chemical precipitation in aqueous solution (ion exchange reaction between zinc acetate and sodium sulfide with addition of manganese acetate and sodium hydroxide) in the presence of glutathione that creates a steric barrier preventing flocculation and precipitation of the nanoparticles.
