Objective: To describe the surgical technique of complex distal femoral deformity correction with the aid of stereolithography apparatus (SLA) biomodels, stabilized with locking plate fixation. Methods: Full-size replica epoxy bone biomodels of the affected femurs (4 dogs/ 5 limbs) were used as templates for surgical planning. A rehearsal procedure was performed on the biomodels aided by a guid...

Because patient bone defects are usually varied and complicated in geometry, it would be preferred to fabricate custom-made artificial bone grafts that are anatomically specific to individual patient defects. Using a rabbit femoral segment as a bone reconstruction model, we successfully produced customized ceramic scaffolds by stereolithography, which not only had an anatomically correct extern...

The surface finish is critical for applications such as optics, micro-fluid flow and mechanical assembly, in which optical lenses, fluidic channels and rotating components are all required to be smooth. However, the stair-stepping effect is well known in the layer-based additive manufacturing processes, in which a three-dimensional model is approximated by a set of two-dimensional layers. Conse...

OBJECTIVES This study investigated the feasibility, accuracy and clinical potential of creating polymer hard copies of echocardiographic data using stereolithography. BACKGROUND Three-dimensional (3D) echocardiography has so far been limited by the need to display reconstructed 3D objects on a two-dimensional screen. Thus, tangible stereolithographic polymer models created from echocardiograp...

The trade-off between process speed and resolution in microstereolithog-raphy (µSL) roots on the diffusion-limited kinetics of photopolymerization. Using a numerical model, we have investigated the influence of diffusion dominant effect under high photon flux. Radical depletion turned out to limit the smallest feature achievable to the order of 10 µm under high process speed. A solution of puls...

Solid Freeform Fabrication methods based on photopolymerization (e.g. stereolithography SLA, digital light processing DLP, two photon absorption TPA) offer the possibility to shape complex structures with high feature resolution and excellent surface quality. If these methods are to be used for applications in regenerative medicine, new photopolymers with defined functional and mechanical prope...

Ceramic and glass materials exhibit desirable properties for various applications. A glass-ceramic composite material could be utilized as an alternative to pure ceramic materials, with a reduced energy requirement processing recycling. In this work, customized photosensitive pastes containing zirconia particles were created processed by stereolithography. Complex 2- dimensional 3-dimensional H...

Stereolithography is an additive manufacturing process, which makes it possible to fabricate useful complex 3D ceramic parts with a high dimensional resolution, good surface roughness and properties close those obtained by classical routes. Previous work concerning LTCC components, demonstrates that possible, coupling the stereolithography robocasting processes, obtain multi-material components...

Stereolithography is a lithography-based additive manufacturing technology, in which liquid photoreactive resins are solidified by ultraviolet or visible light layer-wise approach. Additive technologies used personalized medicine, for example, the production of otoplastics, dentistry, prosthetics but also tissue engineering. Here, biocompatibility produced parts mandatory. In this work chemistr...
