theatre for the musical Grace in Amsterdam. His only son “Casper” was born in 2001. This year was marked by the events of 9/11 which threw back the interest in 3D technology by years. The economic situation forced him to accept a position in a furniture company for three years. In 2004 he moved to Jezet-Seating where he designed and produced theater seats as a consultant. In the same year he was invited to an international conference in London, he presented his invention to use several computer programs in combination to calculate his complex artistic forms. This innovative application of technology has been well received by architects such as Sir Norman Foster and Zaha Hadid and is still revolutionary today. He was one of the first to use “polygonal modelling” in combination with Rhino and designed and realized (2008) for the Blackpools Grand Theater the 1’110 theatre seats in traditional design combined with New World technology. The” C-Stone” and the “C-Bench” by Peter Donders, are machine-made from a single string of carbon that has been guided around a temporary mandrel. The result is an airy but strong structure, described by Rob Cassy (The Garden Design Journal) as ‘calligraphy in 3D’. firstname.lastname@example.org The chair “Batoidea”, designed for the design competition and produced in 3D-printed sand casting, was presented at the Moscow Design Week 2011 in the same year and subsequently presented at various exhibitions in Europe. Many other revolutionary designs in various shapes and materials followed, especially for furniture and jewellery. Since 2013 he has been teaching 3D print product design at the SYNTRA school in Belgium. In 2015 the Ti-join chair was part of the MAKING A DIFFERENCE / A DIFFERENCE IN MAKING Exhibition.25 years 3D Printing by Materialise, Belgium. 2017 Peter was invited by the Hong Kong Council to a reading about his 3D print designs Shelly” can be described as the next major milestone as a chair made of 3D die-cast bronze. The 37kg bronze chair with its open structure, based on the Art Nouveau style, combines the latest technology with lines drawn from nature. Today Peter Donders lives together with his son and works in Bree, Belgium.
