One Step manufacturing process of complex parts by SPS sintering

managed by Toulouse Tech Transfer


Current methods for manufacturing complex parts are not fully satisfactory: loss of material, length of process, materials with imperfect performances... Spark Plasma Sintering (SPS) is a rapid densification technique which allows to get materials exhibiting higher performances. Combining this technology with a method for producing complex shapes is today possible.
- Manufacturing process of complex parts to nearest dimensions, so called near net shape
-> Use of a sacrificial material (possibly of different and less expensive kind)
-> Creation of mobile interfaces
-> Evolution of the mobile interface during the densification: support the formation of the part to its final dimensions
- One step process
- Manufacture of several parts in a single matrix
- Fast production of high performances parts

Readiness Level (TRL)

technology validated in lab(The pie chart refers to the entire portfolio contained in the database of the helpdesk)

Technology Readiness Levels (TRL) are a method of estimating technology maturity of Critical Technology Elements (CTE) of a program during the acquisition process. The use of TRLs enables consistent, uniform, discussions of technical maturity across different types of technology.
