At present laser printing has not been drawn many attention as a manufacturing technique. But it offers an interesting alternative to inkjet printing for many digital manufacturing applications. We first give a short comparison of both printing techniques before presenting an efficient production method for highly complex biochips – peptide arrays – based on laser printing. Peptide arrays are powerful tools for developing new medical substances as well as for diagnosis and therapy techniques. The new production method will enable the potential of peptide arrays to be effectively utilized for the first time.
