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

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.

-From anatomical modeling to surgical planning, precision prosthetics and active and wearable devices silicones AM will enable and accelerate patient specific solution.
-From creating new alternatives in Prototyping to low volume/small manufacturing as well as the possibility to achieve highly complicated or customized designs AM combined with the properties of silicones will allow to respond to unmet needs.

In such 3D-print conference, will give examples of changing the value chain.
Indeed, AM can simplify inventory management of existing silicone objects, since it involves almost exclusively keeping silicone formulation in reserve or proximity accessible to 3D-silicone printers. As each object is produced on demand and in small volumes, a significant part of the costs associated with storage is saved, both for incoming materials and for outgoing parts. One can imagine also replacing broken or defective silicone parts immediately by on site 3D printing according manufacturer standardized AM process. In such a way to manage the local production of 3D printed silicone objects, we have also to consider a supply-chain closer to the end-user.

Interview

What drives you?
AM of elastomers and more specifically silicone elastomers.

Why should the delegate attend your presentation?
AM of silicone elastomers is relatively new and it is key to understand the different technologies available with advantages and drawbacks . It is also the opportunity to explain why and how AM of silicones pulls innovation.

What emerging technologies/trends do you see as having the greatest potential in the short and long run?
Today / True elastomers can be obtained with Liquid deposition modeling AM
Tomorrow / UV elastomers will allow to make huge number of objects in a short time with high speed AM processing and low energy consumption.

What kind of impact do you expect them to have?
Will Reduce stocks and shorten manufacturing time by production near to customers.

What are the barriers that might stand in the way?
Accuracy and Standards for qualification of each set of production.
