Master Thesis - Characteristic of additively manufactured surfaces

LET’S TALK ABOUT YOU

Your profile

• Student at MSc level with focus in mechanical engineering and material science

• Have good knowledge about material characterization

• Is structured and can communicate well.

• Who can find own ways and solutions to challenges

Your responsibilities

• We are now looking for a student to take on the assignment “Identification and definition of characteristic of additively manufactured surfaces”.

The assignment

Additive manufacturing, AM, also commonly known as 3D printing, is an advanced manufacturing process. At Siemens Energy we use mainly an AM method called SLM that welds metal powder layers together with a laser to create three-dimensional objects. The AM process can create geometries with complex features and small internal channels, that the conventional manufacturing methods finds problematic and expensive to produce. 

As all new technologies, the AM technology continuously challenge set ideas, methods and tools that have been develop and used for many years in the conventional prototyping and manufacturing. One of the many challenges that AM faces is the high surface roughness of the printed material. The surface roughness creates problems for many of our flow calculation methods, because of the small size difference between the channels in the geometry and the surface roughness on the channel walls. To take the next step to improve our flow calculation methods and tools we need to learn more about our printed surfaces. 

In this thesis we want the student to help us learn more about AM printed surfaces. More specifically: What do an AM surface look like? How is an AM surface changing when different parameter such as print angle, material, position on build plate, etc. is changed?  What are the main characteristics of an AM surface? How can we describe an AM printed surface statistically? 

The thesis will be split into two parts:

• Scanning additively manufactured surfaces with optical- or/and electron-microscope. 

• Create surfaces from the scanning results and characterize the surfaces to find out how the surfaces varies depending on different parameters. 

The student will be hired by Siemens Energy, but the practical microscopy work will be done at Linköping University.
