Abstract
Electrophotography - the second wide spread digital printing technology beside ink jet - is on the way to prove its capabilities as a manufacturing technology, at least for applications in biofabrication. On DF2008 we first introduced a novel and highly efficient manufacturing process for biochips (peptide arrays) based on electrophotography. After the major scientific goals were achieved the step towards a series production has been made in the last two years. We now present the biochip printing facility capable for a series production. Additionally, we introduce the application of electrophotography as a rapid prototyping technique for the (potential) production of artificial tissues. Similar to other rapid prototyping techniques 3D-structures are build layer by layer from toner powders. Since different approaches to manufacture scaffolds for tissue engineering have been made until today the comparison of the results is interesting.
