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.

Presentation / interview with César Stüpp, Brightlands Materials Center / TNO.

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%, which results in stronger parts.

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.

Avio Aero 3Dprints parts for the Catalyst engine for the Cessna Denali

Up to ten GE Catalyst components will be produced in this area. The engine’s first flight is scheduled for the end of 2019. It is the first turboprop engine in the world with almost 30% of its internal metal parts 3D printed. In Brindisi, work has already begun on three of these ten additive components. This number will continue to grow as the number of GE Additive-Concept Laser machines DMLM (Direct Metal Laser Melting) does.

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.

Embedding Unique Functionalities in composites by continuous fiber printing – Presented by Andrea Gasperini, Brightlands Materials Center

Andrea Gasperini, Brightlands Materials Center, will hold his talk at 3D Printing Materials Conference on April 16, during the 3D Printing Event at Brightlands Chemelot Campus in The Netherlands.

The presentation will provide initially an overview over the range of possible sensors (pressure, elongation, flexural) that have been embedded in composites by exploiting the freedom in fiber positioning by FDM. The response of continuous carbon fibers as a function of flexural load will be presented in a more comprehensive fashion.
