NETZSCH interviews Additive Manufacturing Experts

In free webinars, Dr. Natalie Rudolph chats with experts from both academia and industry about their work and research with Additive Manufacturing (AM) technologies to answer some of the pressing questions we received from our viewers of the Basics series. They answer those questions and share important insights and knowledge.


Metal and Polymer Powder Bed Fusion

Thursday, April 22, 2021 / 10:00 AM - 11:00 AM CDT / 5:00 PM - 6:00 PM CEST

The Additive Manufacturing technology Powder Bed Fusion (PBF) is the most used technology due to the potential use of metal and polymer materials. Furthermore, the use of powder feedstock delivers on the promises of design freedom and absolute flexibility to produce individual parts. 
In response to our Basics AM video series (click here to watch), we received many questions about the differences between metal and polymer AM. For that reason, Dr. Natalie Rudolph interviews one of the leading experts on both processes, Prof. Dr. Katrin Wudy from the Professorship of Laser-Based Additive Manufacturing at the Technical University Munich. Prof. Wudy will answer the viewers’ questions such as:

  • Differences and common features in metal and polymer powder bed fusion,  handling and some machine specifics
  • Powder feedstock availability for additive manufacturing applications 
  • Powder consumption for the part production in the additive manufacturing process
  • Market insights: Size, growth rate, manufacturers of printers, average marketing prices and standardization
  • Typical characterization methods to understand the material behavior

Our special guest today: Prof. Dr. Katrin Wudy

Dr. Natalie Rudolph welcomes Professor Dr. Katrin Wudy from the Technical University of Munich to answer your specific questions.

Professor Wudy (https://www.mw.tum.de/lbam/home/) is a specialist in laser based additive manufacturing and one of the only experts in the world who works and studies both metal as well as polymer powder bed fusion processes.

Prof. Wudy studied plastics and rubber engineering at the University of Applied Science Würzburg-Schweinfurt and finished her PhD at the Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) in the field of powder and beam based additive manufacturing in 2017. From 2015 to 2019, Prof. Wudy headed the "Additive Manufacturing" working group at the Institute of Polymer Technology and was Managing Director of the CRC 814 "Additive Manufacturing" at the FAU. In 2019, Prof. Wudy was appointed as Assistant Professor for laser-based Additive Manufacturing at the TUM. 


Material Extrusion from Prototype to Real Application

Thursday, May 20, 2021 / 10:00 AM - 11:00 AM CDT / 5:00 PM - 6:00 PM CEST

Material Extrusion is one of the most widespread forms of 3D printing representing the largest number of industrial 3D printers as well as a big home user market. In this interview with Dr. Natalie Rudolph, Dr. Tom Mulholland explains how to optimize your complete process to solve technical and design issues. 

In this first of two webinars, we will discuss the importance of understanding materials and identifying the right one for your application.

By looking at Essentium’s broad material portfolio, we will examine many different materials, filaments, applications and future innovations.

Furthermore, Dr. Mulholland will discuss many of your most frequently asked questions, including: 

  • How to save costs and time by optimizing your process
  • How to find the right material for your particular application and production setting
  • What kind of material is important and what will be developed in the future
  • Which sector or industry is growing the most and has the highest potential
  • How to speed up your process

Our special guest today: Dr. Tom Mulholland

Dr. Natalie Rudolph welcomes Dr. Tom Mulholland from Essentium to answer your specific questions. 

Dr. Mulholland (https://www.essentium.com/) is a specialist materials engineer and expert in the field of material development for material extrusion processes.
  
Dr. Mulholland received his Master’s degree in Mechanical Engineering at the University of Wisconsin-Madison. Afterwards he worked at the ICIPC in Colombia as an applied researcher before he went back to his alma mater to obtain his PhD degree.  


Understanding Material Properties for Industrial Material Extrusion

Thursday, June 17, 2021 / 10:00 AM - 11:00 AM CDT / 5:00 PM - 6:00 PM CEST

Finding the right material is one of the most important parts of every additive manufacturing process. Dr. Natalie Rudolph and Dr. Tom Mulholland will explain which properties are important for high quality and efficient production of filament and the successful Material Extrusion printing. 

Get insights into the development of materials for different applications and see how they affect the processing behavior, for example chemical resistance or flame retardance. 

Dr. Natalie Rudolph and Dr. Tom Mulholland meet for a second interview to answer more of our viewers’ questions such as:

  • What is most important to achieve good flow behavior? 
  • What is the cause of delamination and how can you reduce warpage? 
  • Which properties are important to make a material printable?
  • Why is temperature so important for crystallization and to optimizing your cooling process?

Digital Light Synthesis of UV-Curable Materials

Thursday, July 22, 2021 / 10:00 AM - 11:00 AM CDT / 5:00 PM - 6:00 PM CEST

Digital light synthesis, as a variation of the Vat Photopolymerization process, is one of the most promising additive manufacturing technologies for production at scale. 
Dr. Natalie Rudolph and Dr. Alec Redmann discuss the advantages and disadvantages of this special 3D-printing method, take a look at unique UV-curable materials and show how additive manufacturing can be used creatively to enhance other, conventional manufacturing technologies such as high-performance composite production.
Dr. Redmann will explain the dual cure approach where UV curing during the 3D printing process is combined with a subsequent thermal curing stage to reach thermally stable properties over the service life of the parts. 
Furthermore, they will discuss some of your most frequently asked questions, including: 

  • What makes the printing process so much faster and why is it so important? 
  • Can you build large and heavy parts with the top down DLS method?
  • Is it possible to add extra material during the printing process?
  • How to combine different materials to get perfect functionality and why is thermal analysis so important for the process?
