Through reduced 3-D printer cost, increased usability, and greater material selection, additive manufacturing has transitioned from business manufacturing to the average prosumer. This study serves as a representative model for the potential future of 3-D printing in the average American household by employing a printer operator who was relatively unfamiliar with 3-D printing and the 3-D design...

the aims of this study were to determine hippuric acid and toluene in urine samples, airborne toluene levels, health effects, and to describe any correlation between specimen samples. seventy-five printing workers exposed to toluene at work (exposed group), and 60 nonexposed people (control group) were studied. study participants were selected from same factories in the different positions. uri...

We present a printer that builds functional three-dimensional structures by reversible assembly of a discrete set of components, “digital materials”. This approach uses the components rather than a control system to impose the spatial and functional constraints. Printing can be performed as a parallel rather than a linear process. The printing process is reversible for re-use of the pieces or f...

Objective(s): Tissue engineering aims to achieve a tissue, which has highly interconnected porous microstructure concurrent with appropriate mechanical and biological properties. Materials and Methods: Therefore, the microstructure scaffolds are of great importance in this field. In the present study, an electroconductive poly-lactic acid (EC-PLA) filament used to fabricate a porous bone ...

Three-dimensional (3D) printing is a transformative technology with a potentially wide range of applications in the field of orthopaedic spine surgery. This article aims to review the current applications, limitations, and future developments of 3D printing technology in orthopaedic spine surgery.

A ‘button-shaped’ three-dimensional (3D) radio-frequency identification (RFID) tag combining 3D printing and inkjet printing technologies in fabrication for the first time is proposed. The button shape facilitates the tag’s integration with clothes for the purposes of identification and access control. The proposed tag features a compact size (radius 15 mm, height 7.5 mm) and a good performance...

BACKGROUND & OBJECTIVES With improvement in the early diagnosis of breast cancer, breast conserving therapy (BCT) is being increasingly used. Precise preoperative evaluation of the incision margin is, therefore, very important. Utilizing three dimentional (3D) images in a preoperative evaluation for breast conserving surgery has considerable significance, but the currently 3D CT scan reconstruc...

Three-dimensional (3D) printing, also referred to as additive manufacturing, is a technology that allows for customized fabrication through computer-aided design. 3D printing has many advantages in the fabrication of tissue engineering scaffolds, including fast fabrication, high precision, and customized production. Suitable scaffolds can be designed and custom-made based on medical images such...
