AI Article Synopsis

  • Additive manufacturing, commonly known as 3D printing, allows for the rapid production of devices made from various materials like polymer, metal, ceramic, and composites, which traditional methods struggle to create.
  • A key focus is on developing multi-material devices, where there have been successful commercial applications in some 3D printing techniques, but limited progress in stereolithography.
  • This study offers an in-depth strategy encompassing construction, material innovations, software management, and multi-material printing aimed at creating intricate structural details at the micrometer scale, concluding with a review of the findings and potential advancements.

Article Abstract

Additive manufacturing, or nowadays more popularly entitled as 3D printing, enables a fast realization of polymer, metal, ceramic or composite devices, which often cannot be fabricated with conventional methods. One critical issue for a continuation of this success story is the generation of multi-material devices. Whilst in fused filament fabrication or 3D InkJet printing, commercial solutions have been realized, in stereolithography only very few attempts have been seen. In this work, a comprehensive approach, covering the construction, material development, software control and multi-material printing is presented for the fabrication of structural details in the micrometer range. The work concludes with a critical evaluation and possible improvements.
