Mechanical Properties of Austenitic Stainless Steel Made by Additive Manufacturing
Using uniaxial tensile and hardness testing, we evaluated the variability and anisotropy of the mechanical properties of an austenitic stainless steel, UNS S17400, manufactured by an additive process, selective laser melting. Like wrought materials, the mechanical properties depend on the orientation introduced by the processing. The recommended stress-relief heat treatment increases the tensil...
متن کاملPossibilities of Preoperative Medical Models Made by 3D Printing or Additive Manufacturing
Most of the 3D printing applications of preoperative models have been focused on dental and craniomaxillofacial area. The purpose of this paper is to demonstrate the possibilities in other application areas and give examples of the current possibilities. The approach was to communicate with the surgeons with different fields about their needs related preoperative models and try to produce preop...
متن کاملFabrication of Hollow Custom Made Silicone Finger Prosthesis : a Clinical Report
83 ABSTRACT Amputation of a finger can lead to functional, psychological and social problems. Since decades, many treatment modalities have been tried for the rehabilitation of varying degrees of defect which range from self or adhesive retained acrylic or silicone prosthesis to osseointegrated implant retained finger prosthesis. Unfortunately, none of the treatment options has gained much acce...
متن کاملImage-guided Fluid-structure Interaction Simulations of Heart Valve Prosthesis
INTRODUCTION In spite of significant recent advances in imaging modalities for studying cardiac hemodynamics, present day in vivo measurement techniques can only resolve large scale blood flow features. Understanding flow patterns in the heart at physiological conditions and scales sufficiently fine for establishing quantitatively links between disease and patientspecific hemodynamics continues...
متن کاملA mechanical analysis of the closed Hancock heart valve prosthesis.
In order to obtain mechanical specifications for the design of an artificial leaflet valve prosthesis, a geometrically non-linear numerical model is developed of a closed Hancock leaflet valve prosthesis. In this model, the fibre reinforcement of the leaflet and the viscoelastic properties of frame and leaflets are incorporated. The calculations are primarily restricted to 1/6 part of the valve...
