Who we are

About LayerWise 9

Who We Are LayerWise was incorporated in 2008 as a spin-off from K.U.Leuven-PMA

Unique technological expertise in Metal Additive Manufacturing since 2001

Developing new AM applications together with clients


LayerWise Mission 10

Who We Are

Increase your added value

through advantages of

Metal Additive Manufacturing

Therefore LayerWise offers its technological expertise realized by

being technology developer as well as technology user


Industrial applications

Production parts 13

Additive manufacturing

Same material

Same characteristics

What is the added value?


Innovate! 14

cooling & heating

enhance flow

isolation

weight reduction

function integration

save time

save cost


Partner: Von Karman Institute, Belgium

Case: Supersonic turbine blades


Project goal

16


Scaled turbine vane model Improve efficiency:

achieve higher turbine expansions

reduction of shock waves at vane edge

more compact engines

By pulsated blade cooling instead of continuous cooling

Simulations vs. wind tunnel testing



17

Functionalities Complex 3D

Cooling cavity

Fine instrumentation channels

Thin walls

No leakage

Weight saving

Cost saving
