Universal Acoustic Digital Light Processing 3D Printing

Project description

Surpassing the material limits of 3D printing

While 3D printing has changed manufacturing, it has hit a ceiling. Most systems are limited to a single, uniform material, and fall short when it comes to high-performance composites or bio-integrated structures. The main challenge is spatial control (getting tiny fibres or living cells to sit exactly where they need to be within a resin). The ERC-funded UniADLP project aims to solve this problem. Specifically, it will use ultrasonic fields to orient these particles during the build. By manipulating the internal structure of a part in real-time, this technology enables the production of materials with customised mechanical properties and complex biological functions. It will bridge the gap between simple prototyping and advanced bioengineering.

Objective

3D printing, or additive manufacturing, has the potential to drastically transform fields such as architecture, aviation, sportswear, robotics, biomedical devices, implants, and tissue engineering. There is an increasing demand for 3D printing of reinforced composites and biological architectures. The 3D printing of composites is technically challenging due to the need to controllably orient and print microparticles. Commonly used 3D printing technologies achieve customizable prototypes using only a single material, and to date, few printers permit the incorporation of microparticles and living cells. Consequently, current methods allow only limited customization of the mechanical properties of printed objects. Acoustics permit microparticles to be manipulated noninvasively. In this proposal, UniADLP, we will develop a novel acoustic-based 3D printer with which microparticles can be aligned and selectively polymerized to develop a user-defined 3D printed object. We will assimilate homogeneous and heterogeneous microparticles while dynamically orienting them during the printing. This proposal will open up a new and exciting area in the field of additive manufacturing, using ultrasound to print reinforced architectures.
