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).

Why is looking at the complete 3D Printing Value Chain much more important than looking at a 3D Printer alone?

value chain

So far, the emphasis of the 3D Printing / Additive Manufacturing industry has been predominantly on the 3D Printer technology and not on the Value Chain. 3D Printers should be faster, smaller, etc. However, the design phase, the materials and post-processing are equally or even more important. And if one wants to grow towards manufacturing, the integration of 3D Printing / Additive Manufacturing in the ‘traditional’ factory is essential as well.

Roughness reduction and functional coating deposition on additive manufactured substrates with ultrasonic spray coating

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.

The Disruptive Effects of 3D printing on Supply Chains & Business Models

Robert Martens

by Robert Martens, 3D Strategies

By using 3D printing, items can be designed optimally, removing limitations required by traditional manufacturing techniques. With this disruptive technology, objects can be created in small lots or even single and unique pieces without incurring the substantial extra cost that standard production processes would require.

Because local production in short times is possible, reduced spare parts stocks or special tools are needed, and waiting on long-lead items can be substantially shortened. Uncoupling design and production enables local production leading to the rise of advanced business models and supply chains.

ISO/TC 261 the technical committee of standardization in the field of additive manufacturing works together with ASTM F42 Committee. The work here created is followed and the standards are adopted by CEN TC438. Currently this committee has published 14 standards, have 23 standards under development in the 7 active work groups.

The standards are developed under the topics concerning AM processes (hard- and software), terms and definitions, test procedures, quality parameters, supply agreements and all kind of fundamentals.

Laser polishing of 3D Printed Plastic Components

by Karsten Braun, Scientist, Fraunhofer Institute for laser technology ILT

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.

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.

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.
