3D printing makes on-demand and on-site manufacturing possible, shortening the production chain and lowering the amount of waste produced. It is a practical manufacturing method for small objects, additions, moulds, complicated or tailored complex geometries and light structures. The main advantage of the 3D-printing is the possibility for direct manufacturing from the CAD data. Currently the method is mostly being used for metals, plastics, ceramics and food.  Novel applications include custom-made consumer goods, bioprinting or tissue engineering and medical devices.

Cellulosic materials offer a sustainable and biodegradable alternative to the currently used 3D-printing materials, which under processing might generate harmful emissions and even allergenic compounds. Cellulose is non-allergic, tolerating high temperatures, and is an excellent electric insulator material, which can be processed with many 3D-printing methods. The wide modification potential of cellulose further spreads the application field of 3D-printed cellulosic materials.

This webinar discusses the basic properties for successful 3D-printing of cellulosic materials and selected case studies will be covered. Since native cellulose is not thermoplastic, it cannot be processed similarly with 3D-printers as plastics. Cellulosic materials include wood powders, fibres, fibrils, and polymeric cellulose. These materials have varying properties, enabling a wide range of different type 3D-printed applications. In this presentation, we summarize basic concepts to process cellulosic materials through 3D-printing.

Panu Lahtinen, Senior Scientist
Mr. Panu Lahtinen is a Senior Scientist and a project manager at VTT Technical Research Centre of Finland. He has been working for VTT since 2002 in projects related to nanocellulose (CNF), 3D printing, digital printing, fibre-based packaging, mouldable fibre web, and biomaterials. He specialises in the fibre and biomass processing and has an extensive knowledge in CNF production and characterisation. Since 2008 he has been managing the production, quality control and assurance of cellulose nanomaterials at VTT. Current activities relate mainly to CNF and the refining of different food and agro biomass by-products. He is a graduate engineer from Aalto University and he holds a Master’s degree in Paper Technology. He has also completed studies in the field of Industrial Management.
