Flexible additive production processes for the manufacture of customised bio-based packaging 

Bio-based compostable individual package

Due to political and social circumstances, the packaging industry is subject to strong change and pressure to innovate. Packaging that is in line with environmental and climate goals is being sought. From an ecological point of view, these should be bio-based and also either biodegradable or recyclable. Energy recovery or landfill recycling should be avoided as far as possible.

Packaging is a very price-critical product, which makes the introduction of new materials, technologies and process chains per se difficult from an economic perspective. These problems are to be overcome by rapid additive manufacturing in combination with bio-based material systems. Bio-based polymers and renewable raw materials with residual material character, which have not been used in additive manufacturing processes so far, but which offer enormous application potential through upcycling, serve this purpose.

By using 3D printing technologies with particularly high throughput and intelligent, material-saving design, these can be manufactured in an economically competitive cost segment. In this context, individual packaging of low to medium quantities and thus currently high unit costs are to be considered.

„Process development for paper fibres in binder jetting for packaging“

Paper fibre packagingBinder jetting (also 3D printing, 3DP) is one of the fastest additive manufacturing processes, which convinces with an enormous material variety of possible powders. Especially the use of a matrix and binder powder in combination with a water-based printing fluid have an enormous potential for new matrix materials. In this way, residual materials can also be used to make better use of our resources as well as to achieve further material recycling and the associated upcycling. In addition, suitable binder powders must also be found to make targeted applications possible.


In this project, paper fibres from the packaging industry are to be used to produce new interior fittings as packaging inserts.
