“…Because visible-spectrum DMD-based projectors are now accessible to the mass market, these printers can be made for $1-2 K. However the sourcing of compatible photoinitiators is an added complication to using visual spectrum photon sources. Several scaffold and cell printing studies have been conducted using DMDPP, including biodegradable PPF [44] and PLGA-PEG-HEMA [45] scaffolds, fibronectin-modified PEGDA-MAA scaffolds [46], hybrid PEGDA-AA/PEGDA scaffolds [47], and GelMA scaffolds [48]. Despite DMDPP being a relatively nascent technique within the field of biofabrication, direct printing of cell-laden hydrogels is likely in the near future given its many advantages, low cost, and ease of adoption.…”

“…Conventional stereolithography has been successfully applied for the fabrication of tissue-engineered constructs using several natural and synthetic materials [58,68,115]. However, the fabrication of porous 3D constructs with an interconnected micro-architecture is limited by the resolution of the system [27]. Microstereolithography is a process that evolved from conventional stereolithography, allowing the fabrication of complex 3D constructs with a micro-scale resolution of about 200 nm [27,55,71].…”

Stereolithography is an additive technique that produces three-dimensional (3D) solid objects using a multi-layer procedure through the selective photoinitiated curing reaction of a liquid photosensitive material. Stereolithographic processes have been widely employed in Tissue Engineering for the fabrication of temporary constructs, using natural and synthetic polymers, and polymer-ceramic composites. These processes allow the fabrication of complex structures with a high accuracy and precision at physiological temperatures, incorporating cells and growth factors without significant damage or denaturation. Despite recent advances on the development of novel biomaterials and biocompatible crosslinking agents, the main limitation of these techniques are the lack number of available photocrosslinkable materials, exhibiting appropriate biocompatibility and biodegradability. This chapter gives an overview of the current state-of-art of materials and stereolithographic techniques to produce constructs for tissue regeneration, outlining challenges for future research.

Fabrication and analysis of cylindrical resin AFM microcantilevers

et al. 2011

a b s t r a c tIn this paper a new method of fabricating cylindrical resin microcantilevers using the Direct Digital Manufacturing (DDM) technique of Micro-stereolithography (MSL) is described. The method is rapid and commercially viable, allowing the fabrication of atomic force microscope (AFM) cantilevers which exhibit much larger spring constants than those currently commercial available. This allows for experimentation in a force regime orders of magnitude higher than currently possible using the AFM. This makes these cantilevers ideally suited for AFM-based depth sensing indentation. Due to their geometry, the assumptions used in the standard Euler-Bernoulli beam theory usually used to analyse AFM cantilevers may no longer be valid. Therefore approximate analytical solutions based on Timoshenko beam theory have been derived for the stiffness and resonant frequency of these cantilevers. Prototypes of the cantilevers have been fabricated and tested. Results show good agreement between experiment and theory.
