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

César Stüpp

by Cesar Stupp, Brightlands Materials Center

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.

Interview

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.

Aligning molecular and structural dynamics in additive manufacturing of thermoplastics; towards enhanced weld mechanics and geometrical stability

by Jules Harings, Maastricht University, Aachen Maastricht Institute for Biobased Materials

Additive manufacturing is a technology that develops rapidly as a niche within the field of discrete manufacturing. Unique products of high added value rely on customisation and nearly endless design flexibility and are progressively introduced in automotive, aerospace, art and medical industiesy. Nevertheless, despite successes with metals and living materials, a mismatch in product quality and expectations has been the Achilles’ heel in the mass adoption of thermoplastics in 3D printing, especially in fused deposition modelling (FDM).

Roughness of as-printed 3D parts is limiting the real breakthrough of Additive Manufacturing. Post processing technologies consist out of subtractive techniques such as grinding or sanding, or out of additive techniques such as coating.

Laser polishing of 3D Printed Plastic Components

Despite their great potential for individualization, 3D-printing processes for polymer parts like SLS (Selective Laser Sintering) and FDM (Fused Deposition Modeling) have the particular disadvantage of a high surface roughness; therefore, surface finishing is often necessary. However, current finishing procedures often have deficits such as low flexibility, long process times or incorporation of abrasives in the component. Therefore, Fraunhofer ILT is developing a non-contact, laser-based polishing process for additively manufactured plastic components.

How Silicones Additive Manufacturing is a remarkable growth driver for production of soft materials

Jean Marc Frances

by Jean Marc Frances, Scientific & Technology Coordinator for Elkem Silicones R&D

In order to respond to the increasing demand for new materials, Elkem Silicones has developed a new series of customized silicones especially designed for the use by Additive Manufacturing (AM).

These silicone series are intended to be used by Liquid Deposition Modeling. A technology based on extrusion principles. Indeed AM opens up new horizons for the use of silicones as a novel high performance material and as other materials it will affect existing global value chains.

Industrializing AM and merging the worlds of additive manufacturing and machining – Presented by Stijn Brilman, cards plm solutions

Stijn Brilman, cards plm solutions, will speak at 3D Printing Design & Engineering Conference on April 16, during the 3D Printing Event at Brightlands Chemelot Campus in The Netherlands.

Getting rid of the bin of broken dreams! How do we deliver high quality and accurate metal products? Unfortunately, people often forget that AM is more than the printer and controlling the printing process. In order to realize the full potential of additive manufacturing, companies must employ a robust process that integrates design, engineering, manufacturing planning and production operations.

In this presentation we provide the insights of an end-to-end workflow where AM and machining are combined.

How to boost Additive Manufacturing (AM) for serial production? Opportunities to improve AM processes and Machines – Presented by Abdellatif Bey-Temsamani, Flanders Make

Abdellatif Bey-Temsamani, Flanders Make, will speak at 3D Printing Design & Engineering Conference on April 16, during the 3D Printing Event at Brightlands Chemelot Campus in The Netherlands.

With the industrial transition to use Additive Manufacturing (AM) for Series Production, AM machine builders, SW/HW providers and end-users are confronted with different challenges to increase productivity, decrease lead time and produce parts with high quality. The current practice is however far from reaching the desired productivity and quality that are translated to large scrap rate in current production. This presentation will highlight examples for opportunities, based on industrial projects conducted by Flanders Make, to improve the AM process and machines leading to reduce lead time, increase productivity and reduce the scrap rate.

Automated Surface Finishing for 3D-printed metal parts as enabler for serial production – Presented by Wolfgang Hansal, Hirtenberger Engineered Surfaces

Wolfgang Hansal, Hirtenberger Engineered Surfaces will speak at 3D Printing Post-Processing Conference on April 17, 2019, during 3D Printing Event in The Netherlands.

With the evolution of 3D-printing of metals from the prototyping scale towards a serial production the different steps in the production chain must be fully understood and adjusted to the each other in order to guarantee a constant and reproducible quality of the final products. Among the different process steps, the post-processing of AM metal parts is crucial but nevertheless still an open issue at industrial scale.
