Stereolithography and microtechniques
Microsystem Technologies, 1995The laser stereophotolithography is a process which allows the manufacture of 3D parts by a light-induced space-resolved polymerization. In view to obtain microparts, it is necessary on one hand to reduce the polymerization depth and on the other hand the polymerization width in thex-y plane.

Hypertelorism is a deformity characterized by an increase in interorbital distance. The treatment can be orbital mobilization, or if the malformation goes along with occlusal alterations, the indicated treatment is a facial bipartition with hemifacial rotation.The intention of the present study was to describe a surgical planning technique in locating ...

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2000
This paper analyses the causes of errors in stereolithography with a view to deriving methods to compensate for those errors. Two types of errors are discussed: those due to the process of approximating the part and those arising during the building and finishing of the part.

Additiv gefertigte Funktionsbauteile profitieren von den Möglichkeiten des Multimaterialdrucks, indem die mechanischen, chemischen und optischen Eigenschaften lokal variiert werden. Verfügbare Technologien für Polymerwerkstoffe genügen jedoch nicht den Anforderungen hinsichtlich Druckauflösung, Multimaterialdruck- und Biokompatibilitätsfähigkeit ...

Stereolithography of SiOC Ceramic Microcomponents
Advanced Materials, 2015The first example of the fabrication of complex 3D polymer-derived-ceramic structures is presented with micrometer-scale features by a 3D additive manufacturing (AM) technology, starting with a photosensitive preceramic precursor. Dense and crack-free silicon-oxycarbide-based microparts with features down to 200 μm are obtained after pyrolysis at 1000 °

Stereolithography: application to neurosurgery
Critical Reviews in Neurosurgery, 1998Computer-aided design (CAD) and computer-aided manufacturing (CAM) by stereolithography are already being widely used in industry for the design and manufacture of new parts and have already shown accuracy in reproducing the desired model. The only shortcoming of this technique is that it can only make one model at a time, a "prototype." It cannot be ...
