Results of some practical experiments by the surface treatment industry – Presented by Arjan de Bruin, Vereniging ION

Arjan de Bruin, Vereniging ION, will speak at 3D Printing Post-Processing Conference on April 17, 2019, during 3D Printing Event in The Netherlands.

The attention of the industry involved in additive manufacturing for surface treatment seems very small. People are mainly still busy with construction rules, powder compositions and laser technology. The “surface technology” process block is left blank in many presentations. Incorrectly in the opinion of Vereniging ION. After all, if a product is made according to the additive manufacturing method, a state-of-the-art surface treatment is necessary for proper preservation, improvement of material properties or from an aesthetic point of view.

Because the attention for surface treatment in additive manufacturing is still small, it seems that there is hardly any progress from the 3D Metal Printing Working Group of Vereniging ION. However, this is not too bad. Because a lot of research and development work is involved, it is not possible to immediately indicate one solution direction. That is why various tracks are taken.

This technology is important for the surface treatment industry, because in the long term it is expected that around 10% of all metal products will be “printed”. And all these products will also have to be provided with a surface treatment.

The important factors for applying 3D (metal) printing are weight reduction and components with a high complexity. In weight reduction, the aerospace industry and the highly dynamic machine industry are the most important drivers. In the meantime, there are various examples where by applying the new construction rules, weight savings of up to 50% can be achieved. Where the manufacturability of complex products is concerned, this involves a much larger group of companies. Consider, for example, the integration of parts (previously 8 parts becomes 1 part) and components that could not be made at all. Because the production speed is not yet high and the cost price is also relatively high, completely new business models are being looked at.

Although it is not going fast, important steps are also being taken in the area of ​​surface technology.

During this lecture an update:

A basic specification has now been drawn up with a number of large OEMs. Important facets include porosity, particle solidity and surface roughness.
Ways of post-processing and dimensional stability.
In addition to tests with electrochemical and metallic processes, there are now also tests with organic coatings.
The big challenge is still the hollow spaces and the finite (dead end) channels.
Vereniging ION deals with all substrates that are “printed”, but for metal the processes that are looked at are laser cladding, selective laser melting and digital light processing.
In addition to single materials, multiple materials (metal / plastic) and multiple metals are also considered.


What drives you?

New opportunities in a sustainable world through smart collaboration

Why should the delegate attend your presentation?

Innovation in a disrupted technology world: adequate surface treatment often delivers more than you think

What emerging technologies/trends do you see as having the greatest potential in the short and long run?

Innovation through collaboration: smart & cross sectoral production

What kind of impact do you expect them to have?

Make life easier: limit the negative and use the good

What are the barriers that might stand in the way?

Traditional thinking with too limited an eye for mutual interest
