Development of a 3D printer using scanning projection stereolithography

We have developed a system for the rapid fabrication of low cost 3D devices and systems in the laboratory with micro-scale features yet cm-scale objects. Our system is inspired by maskless lithography, where a digital micromirror device (DMD) is used to project patterns with resolution up to 10 µm onto a layer of photoresist. Large area objects can be fabricated by stitching projected images ov...

Use of a 3D printer to create a bolus for patients undergoing tele-radiotherapy

Background: This study describes the possibility of implementing three-dimensional printing technology to create a precise construction of a planned bolus, based on computed tomography information stored in the Digital Imaging and Communications in Medicine (DICOM) format file. Materials and Methods:  To create the bolus with a 3D printer, we converted data in the DICOM format to the s...

Designing of PLA scaffolds for bone tissue replacement fabricated by ordinary commercial 3D printer

BACKGROUND The primary objective of Tissue engineering is a regeneration or replacement of tissues or organs damaged by disease, injury, or congenital anomalies. At present, Tissue engineering repairs damaged tissues and organs with artificial supporting structures called scaffolds. These are used for attachment and subsequent growth of appropriate cells. During the cell growth gradual biodegra...

Thinking like Archimedes with a 3D printer

We illustrate Archimedes’ method using models produced with 3D printers. This approach allowed us to create physical proofs of results known to Archimedes and to illustrate ideas of a mathematician who is known both for his mechanical inventions as well as his breakthroughs in geometry and calculus. We use technology from the 21st century to trace intellectual achievements from the 3rd century ...

Making 3D Replicas Using a Flatbed Scanner and a 3D Printer

This paper describes a novel approach to making 3D replicas of nearly flat objects using a flatbed scanner and a 3D printer. The surface reconstruction is based on the fact that the light in a flatbed scanner shines under a given constant angle and the CCD sensor records different intensities depending on the angle between a local normal vector of a micro-facet and the vector towards the light ...
