Evaluation and prediction of the tensile properties of continuous fiber-reinforced 3D printed structures composite structuresDownload
Three dimensional (3D) printing is a technique conventionally used to manufacture prototypes. Commercial desktop 3D printers have become available which produce functional 3D printed parts. The MarkOne by Mark Forged manufactures printed structures reinforced with continuous Carbon, Fiberglass or...
Tubular braided composites consist of woven fibers imbedded in a resin matrix. Braided composites are manufactured using a device known as a Maypole braider. Braiding machines can be configured to produce several braiding patterns including: Diamond (1/1), Regular (2/2), Hercules (3/3) and...
Purpose – This paper aims to evaluate the material properties and dimensional accuracy of a MakerBot Replicator 2 desktop 3D printer. Design/methodology/approach – A design of experiments (DOE) test protocol was applied to determine the effect of the following variables on the material properties...
Background The primary objective of this study was to develop a computer-controlled three-dimensional friction measuring system, the orthodontic friction simulator (OFS). A clinically-based in vitro experiment considering wet and dry friction for conventionally and self-ligated brackets is...
The effect of short fiber reinforcements on the mechanical properties of cement has been examined using a splitting tensile – digital image correlation (DIC) measurement method. Three short fiber reinforcement materials have been used in this study: fiberglass, nylon, and polypropylene. The...
Two dimensional (2D) tubular braided composites consist of textile fibers imbedded in a resin matrix. Braid geometry and void content will affect the mechanical behavior of the tubular braided composite samples. In this study, tubular braid samples were assessed using micro X-ray computed...
Investigation into the effects of stainless steel ligature ties on the mechanical characteristics of conventional and self-ligated brackets subjected to torqueDownload
Objective: Torque is applied to orthodontic brackets in order to alter the buccal-lingual angulation of a tooth. One factor that can affect torque is the ligation mode used to retain the archwire in the bracket slot. The objective of this study was to investigate the effects of stainless steel...
The Effect on Elastic Modulus of Rigid-Matrix Tubular Composite Braid Radius and Braid Angle Change Under Tensile LoadingDownload
The objective of this paper is to assess changes in braid radius and braid angle of braided composite tubes under tensile loading using stereomicroscope digital image correlation (DIC) based optical measurement techniques. Using this approach, displacement fields were calculated and three...
The design and testing of an orthodontic torque simulator that reproduces the effect of archwire rotation on orthodontic brackets is described. This unique device is capable of simultaneously measuring the deformation and loads applied to an orthodontic bracket due to archwire rotation. Archwire...
Purpose: This paper evaluates the material properties and dimensional accuracy of a MakerBot Replicator II desktop 3D printer. Design Methodology: A design of experiments (DOE) test protocol was applied to determine the effect of the following variables on the material properties of 3D printed...
