A Direct Metal Laser Sintering (DMLS) Root Analogue Implant Placed in the Anterior Maxilla: Case Report

A large residual cyst in the left anterior region of maxilla: A case report

Abstract   Background and Objectives: residual cyst is an odontogenic cyst that develops after a tooth with a radicular cyst is extracted so that all or part of the cyst remain in place.  These cysts are known as asymptomatic inflammatory odontogenic cysts and form approximately 10% of odontogenic cysts.   Case Report: a 30 years old man patient, referred to the department of oral medicine of...

Thermal Stresses in Direct Metal Laser Sintering

In Direct Metal Laser Sintering objects are created by sequential sintering loose metal powder particles by means of laser technology. When the laser sintering process involves temperature gradients, thermal stresses develop. Corresponding residual stresses induce warping of the densified structure leading to unacceptable tolerance losses. This paper examines the role of laser beam scan pattern...

Materials for Direct Metal Laser-sintering

Comparison of Mechanical, Metallurgical Properties of 17-4PH Stainless Steel between Direct Metal Laser Sintering (DMLS) and Traditional Manufacturing Methods

The purpose of this research was to analyze and compare the mechanical properties of parts made using both Direct Metal Laser Sintering (DMLS) and traditional manufacturing methods like casting or forging. Previous research in DMLS was conducted using various materials, but there has been very little done for 17-4PH stainless steel. All the samples used for testing were conducted using the EOSI...

Practical Issues in the Application of Direct Metal Laser Sintering

Direct Metal Laser Sintering (DMLS) was introduced to meet the objective of producing metal parts directly from CAD data. CRDM has accumulated six years of experience in applying this technique, mostly to prototyping parts for evaluation. For some applications, such as blow moulds, porosity generated in DMLS has proved to be beneficial, but for others a concession on tolerances or finish are ne...
