Students at TU Delft Use 4D Printing to Make Products with Origami-Like Characteristics that Change over Time

Students at TU Delft Use 4D Printing to Make Products with Origami-Like Characteristics that Change over Time.A relatively new development in 3D printing is the addition of a fourth dimension: time. Students at TU Delft used this fourth dimension to print a product with origami-like characteristics that changes over time. They did this by using a 3D printer to print a form on a fabric substrate that is held under tension. Along with eight other projects, including a 3D-printed bicycle frame made of rust-resistant steel and 3D models of heart defects that are used to aid doctor-patient consultations, this project is part of the ‘Advanced Prototyping’ exhibition on 27 October at TU Delft.

The ‘4D printer’ is one of the projects that form part of the minor in Advanced Prototyping for third-year students of Industrial Design Engineering at TU Delft. At the exhibition held as part of the minor, students will demonstrate the possibilities and newest developments in the field of advanced prototyping, in collaboration with renowned experts. During the exhibition there will also be a lecture by a special guest: Nadya Peek, a researcher from the Centre of Bits & Atoms at MIT Medialab, who was involved in founding the worldwide FabLab Academy.

Below is an overview of all the projects:

1. Ultimaker XXL
If you turn an Ultimaker 3D printer upside-down and use multiple printers at the same time, you can print large – or extremely large – objects. In the Ultimaker XXL project, this printing method has been used to build a test installation. Particular attention has been paid to the development of new hardware and software solutions to facilitate so-called ‘XXL prints’.

2. Printing cardiac defects for communication and diagnostics
Pictures are often used to help explain a cardiac problem to patients, particularly in the case of congenital heart defects. Patients sometimes have difficulty understanding such explanations. In this project, CT/MRI heart scans were used as a basis for developing and printing ten different physical heart models, so that you can literally hold your heart in your hand. The project paid extra attention to the workflow in medical working environments and to showing defects using colour or transparency, for example.
