New developments of short and continuous fibre printing with exceptional mechanical behaviour and unique functionalities

Additive manufacturing (AM) techniques have been extensively explored in the last decades due to their potential to transform existent production technologies. Fused filament fabrication (FFF) is a very versatile AM technique, although it is widely used for prototyping due to their limited mechanical properties, especially in between layers. To approach this matter, a novel technique was developed in which the strength in between layers was increased in 184%. Also included in the topic are embedded continuous carbon fibers with unique functionalities, used to monitor the structural health of 3D printed parts in real time, decreasing the need for periodical inspections.



What drives you?
The belief that we can develop extremely powerful technologies in a sustainable manner.

Why should the delegate attend your presentation?
Additive manufacturing is one of the most sustainable forms of production. With 3D printing, we explore manufacturing one step ahead, adding unique functionalities to this very promising and environmentally friendly way of developing new ideas.

What emerging technologies/trends do you see as having the greatest potential in the short and long run?
All technologies that are in line with current needs. The most special one is the need for a healthy environment and therefore, circular technologies and the ones that are able to reduce, reuse and recycle are always going to be on top, especially on the long run.

What kind of impact do you expect them to have?
A considerable decrease not only in the amount of waste produced, but also in the overall amount of waste.

What are the barriers that might stand in the way?
The urge of the majority: power and profit.

“Special quote”
Additive manufacturing not only can reduce dramatically the amount of produced material, energy and waste, it is also a very powerful tool in which beyond all advantages, sustainability is key.

About Cesar Stupp

Mr. César Stüpp has a Materials Science and Engineering background. Soon after bachelor, he started a Master degree, working on the development of a novel biodegradable hydroxyapatite reinforced magnesium composite. Later on, he started a Professional Doctorate in Engineering at the Eindhoven University of Technology. During this period, the final assignment resulted in enhancing significantly the overall properties of fused filament fabrication (FFF) printed parts, reducing its anisotropy. To continue working on the development of FFF and help bringing this technology to all applicable areas, he works now as a scientist in the additive manufacturing group in Brightlands Materials Center.

Continuous AM for production – Presented by Jeroen Smeltink, AMSYSTEMS – TNO

Continuous AM for production – Presented by Jeroen Smeltink, AMSYSTEMS – TNO, at the AM Integrated Factory Conference, December 4, 2018, at Brightlands Chemelot Campus, Sittard-Geleen, The Netherlands.

Since its inception Additive Manufacturing (AM) has been the promise for a paradigm shift in production technology and processes. Moving from prototyping towards mass customization and printing on demand, the AM-process now needs to make a further leap. By continuous AM the productivity can be increased and as a result the cost for the production can be decreased.

“Generative design for additive manufacturing” – Presented by Mathijs de Schipper, TNO

Designing smart structures and utilizing the full potential of additive manufacturing requires a new design approach. Using algorithms complex structures can be generated with for example varying thickness resulting a range of material hardness. I will show you my approach towards designing an insole with multiple material properties using Grasshopper.

Working with new materials sometimes requires more control over your printing process. Instead of slicing a 3D object resulting in a file for your printer you can also directly design the toolpath for your printer. For 3D foodprinting we use this approach to create complex textured food. Using a generative design approach you can directly go from design to printing.
