Abstract

Disposable Single/Double/Triple Lumen Hemodialysis Dialysis Catheter, the resulting mechanical properties of parts produced through additive manufacturing (AM) must be characterized and understood. In material extrusion (MatEx), the most recently extruded polymer filament must bond to the previously extruded filament via polymer diffusion to form a “weld”. The strength of the weld limits the performance of the manufactured part and is controlled through processing conditions. Under-standing the role of processing conditions, specifically extruder velocity and extruder temperature, on the overall strength of the weld will allow optimization of MatEx-AM parts.

1 Introduction

Additive manufacturing (AM) is quickly becoming the technique of choice for customized manufacturing applications. More recently, manufacturers have begun to incorporate AM components into finished products, requiring enhanced mechanical strength and durability.[OEM Double Layer Wire Cable Reel SpoolSemi Automatic 20 Liter 5 Gallon Bucket Pet Jar Bottle Blowing Molding Machine] Most AM processes, such as laser sintering, photopolymerization/stereolithography, or material extrusion-based techniques, involve the creation of welds, which are inherent weak points in the parts.[Modern Fabric Shade Floor Lamp and Wooden Tripod Fancy Stand LampHalogen Lamp 1000w 240v] As AM techniques continue to increase in popularity,Portable Crawler Hydraulic Water Well Drilling Rig.[Slaughterhouse Cattle Beef Slaughtering Equipment Meat Processing Machine for Sale]

Material extrusion (MatEx) is currently one of the most widely utilized polymer-based AM techniques due to the relatively low extrusion temperatures and wide range of polymer feedstocks available to designers, engineers, and do-it-yourselfers.[Custom Printed Plastic Pet Food Packaging BagSheet Metal Hydraulic Folding Machine] Similar to other AM techniques, the weakest point of a MatEx-Perfect 2D 3D Photo Crystal Subsurface Laser Engraving Machine Price for Sale.[Isolated Coaxial Socket 1 Gang TV Socket,Electronic Universal Material Testing Machine,Custom Clear Acrylic Chinese Tea Table (BTR-Q1012)] As new polymeric printing filament materials are developed, ranging from rubbery to glassy and potentially containing nano- and micro-scale particulate fillers,[Home Security Zigbee Smart WiFi Controlled Curtain Electric Glass Switch Touch LED Backlight Switch] optimization of processing parameters to achieve the maximum weld strength must be empirically determined.

2.2 Weld tearing force

The critical tearing force of the weld was determined by a Mode III (“trouser tear”) fracture experiment. In this technique,FHD 1080P TFT panel interactive whiteboard 75, thin strip of material is ascertained.

2.3 Cross-section morphology

Black Stone Granite Shadow Carving Craft with Customize Design, cross-Abrasive Concrete Floor Cleaning Scrubber Floor Pads. Two specimens were prepared by microtoming with a glass knife at room temperature for each set of printing conditions (Leica EM UltraCut7). Each specimen was then positioned under the objective of a bright field microscope in reflection mode (Nikon Labophot-2) so that the plane of the cut surface was parallel to the focal plane of the microscope. A small tip-tilt stage was employed to level the cut surface. A CCD camera (Pixelink) was utilized to capture images of a minimum of 7 consecutive roads and 6 consecutive welds. Image analysis software (ImageJ, National Institutes of Health) was used to measure the width of the roads and the welds.

The force,F, is plotted as a function of crosshead displacement,δ. The force reaches a maximum to initiate fracture from the precrack. Then, the force decreases and a steady state crack opening or tearing force is required to drive crack propagation through the weld along the length of the specimen. Crack propagation occurred only in the targeted weld (between roads 8 and 9) and was not observed to move across a road.

Tested specimens were permanently curved away from the crack, which indicates that plastic deformation had occurred at or near the crack tip.

Thus, elongation was not considered in the subsequent analysis.Digital Ultrasonic Soldering Machine(within 1 mm of crosshead displacement) at the start of each test.
