Rapid development in 3D printing technologies promises a cheap and simple yet reliable way for producing various components and structures for research in numerous science fields. This work is dedicated to investigate the possibility to use fused filament fabrication based 3D printing to fabricate microchannels for microfluidical applications as well as diverse 3D scaffolds for biomedical applications. We also examine the possibility to further improve fabricated structures by employing an ultrafast laser, namely by laser light filamentation and using direct laser writing. Results of this study are discussed in detail and outlook for further work in this field is given.

SUMMARY Three-dimensional (3D) printing is a rapidly developing technology that has gained widespread acceptance in dentistry. Compared to conventional (lost-wax technique) and subtractive computer numeric controlled methods, 3D printing offers process engineering advantages. Materials such as plastics, metals, and ceramics can be manufactured using various techniques. 3D printing was introduced over three decades ago. Today, it is experiencing rapid development due to the expiration of many patents and is often described as the key technology of the next industrial revolution. The transition to its clinical application in dentistry is highly dependent on the available materials, which must not only provide the required accuracy but also the necessary biological and physical properties. The aim of this work is to provide an up-to-date overview of the different printing techniques: stereolithography, digital light processing, photopolymer jetting, material jetting, binder jetting, selective laser sintering, selective laser melting, and fused filament fabrication. Additionally, particular attention is paid to the materials used in dentistry and their clinical application.

First Time

In this study, acrylated epoxidized soybean oil (AESO) and mixtures of AESO and vanillin dimethacrylate (VDM) or vanillin diacrylate (VDA) were investigated as photosensitive resins for optical 3D printing without any photoinitiator and solvent. The study of photocross-linking kinetics by real-time photorheometry revealed the higher rate of photocross-linking of pure AESO than that of AESO with VDM or VDA. Through the higher yield of the insoluble fraction, better thermal and mechanical properties were obtained for the pure AESO polymer. Here, for the first time, we validate that pure AESO and mixtures of AESO and VDM can be used for 3D microstructuring by employing direct laser writing lithography technique. The smallest achieved spatial features are 1 µm with a throughput in 6900 voxels per second is obtained. The plant-derived resins were laser polymerized using ultrashort pulses by multiphoton absorption and avalanche induced cross-linking without the usage of any photoinitiator. This advances the light-based additive manufacturing towards the 3D processing of pure cross-linkable renewable materials.

In this work we present current progress on employing direct laser writing (DLW) for creation of 3D microstructures for biomedical applications. Both subtractive and additive variations of DLW allow fabricating structures for in vitro bioanalysis and in vivo tissue engineering. Furthermore, we show that efficiency of 3D microstructure manufacturing can be enhanced by combining femtosecond laser material processing with commercial 3D printers.
