Three-dimensional printing of external airway splints for tracheomalacia

External bioresorbable airway rigidification to treat refractory localized tracheomalacia.

OBJECTIVES/HYPOTHESIS Our study evaluates the efficacy of extraluminal bioresorbable plates to treat refractory localized airway malacia in patients undergoing corrective surgery for complex multilevel laryngotracheal stenosis. STUDY DESIGN Retrospective case series. METHODS Secondary malacic airway segments were characterized (severity, site, type) by a dynamic transnasal flexible laryngot...

A novel three-dimensional printing of electroconductive scaffolds for bone cancer therapy application

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 ...

Robotic positioning device for three-dimensional printing

Additive manufacturing brings a variety of new possibilities to the construction industry, extending the capabilities of existing fabrication methods whilst also creating new possibilities. Currently three-dimensional printing is used to produce small-scale objects; largescale three-dimensional printing is difficult due to the size of positioning devices and machine elements. Presently fixed Co...

In-lab three-dimensional printing

The development of the microscope in 1590 by Zacharias Janssenby and Hans Lippershey gave the world a new way of visualizing details of morphogenesis and development. More recent improvements in this technology including confocal microscopy, scanning electron microscopy (SEM) and optical projection tomography (OPT) have enhanced the quality of the resultant image. These technologies also allow ...
