Stereolithography (SL) is an additive manufacturing (AM) process that uses photopolymers for creating a 3D structure that has excellent surface roughness and allows precision fabrication. Nevertheless, the photopolymer used in this process is generally costly, in particular for medical-grade materials, and a relatively large amount of a photopolyme...

This paper describes an efficient method of fabricating high-performance ceramic (HPC) parts by using solvent-based slurry stereolithography (3S) and sintering. In this study, zirconia was used as the structural material, methyl alcohol was used as the solvent, a waterborne inorganic pigment was used as the dispersant, and a visible-light-curing re...

In recent years, the development of 3D printing in flow analysis has allowed the creation of new systems with various applications. Up to now, 3D printing was mainly used for the manufacture of small units such as flow detection cells, preconcentration units or mixing systems. In the present study, a new 3D printed lab-on-valve system was developed...

We present a novel stereolithographic three-dimensional (3D) printing process that uses Lissajous trajectories. By using Lissajous trajectories, this 3D printing process allows two laser-scanning mirrors to operate at similar high-speed frequencies simultaneously, and the printing speed can be faster than that of raster scanning used in conventiona...
Les phosphates de calcium tels que le β-TCP sont utilisés depuis des décennies comme substitut osseux synthétique. Leurs bonnes propriétés chimiques et leur comportement analogue au tissu osseux in vivo et in vitro peuvent être améliorés par la technique de mise en forme employée. Il est aujourd'hui largement admis qu'une architecture poreuse optim...

IntroductionSagittal synostosis affects 1 in 1000 live births and may result in increased intracranial pressure, hindrance of normal neural development, and cosmetic deformity due to scaphocephaly. Historically, several approaches have been utilized for surgical correction and recently, computed tomography (CT)-guided reconstruction procedures are ...

Three-dimensional printing has evolved dramatically in recent years and is now available for clinical use. Technical operations of 2 of the most common rapid prototyping processes (stereolithography and fused deposition modeling) and the steps involved in the creation of a prototype are discussed. Current applications in human neurosurgery includin...
