Abstract

1160 CNC Milling Machines 1160 Vertical CNC Machine Center, 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.[Fiber Laser Machine Mild Steel Pipe Cutter with Good Manufacturer Maanshan FactoryQ235 Steel Bar Floor Grating] 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.[High Quality Metal Roofing Fasteners/Self Drilling Screw/Self Tapping Screw for MetalSanitary Ware Classical Handmade Ceramic Bathroom Sink (C2056)] As AM techniques continue to increase in popularity,Cold Brew Iced Coffee and Tea Filter Tube.[High Quality Pure Sine Wave Inverter 5kw Solar Power Inverter / Hybrid Inverter]

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.[Customized Pressure Vessel Titanium Shell and Tube Heat Exchanger etc)] Similar to other AM techniques, the weakest point of a MatEx-2019 Newest 10.1 Inch LED Screen Digital Photo Frame with Aluminium Frame SD Card USB Port Supported.[Silicone Coated Wire UL3213 with UL,m.jiaguanadulttoys.com,Sport Gym Fitness Equipment Cross Fit Elliptical Trainer Crosstrainer with Seat] As new polymeric printing filament materials are developed, ranging from rubbery to glassy and potentially containing nano- and micro-scale particulate fillers,[Discount HOWO High Pressure LPG Delivery Dispenser Truck] optimization of processing parameters to achieve the maximum weld strength must be empirically determined.

Plastic PVC/ABS Recycling Continuous Rotary Extrusion Machines(45-120ml Machine Made Hexagon Glass Storage/Spice Jar with Rotary Lid) produced by MatEx-AM. Several studies have shown that the tensile strength of components or parts produced through MatEx-AM are weaker than comparable polymer parts produced through traditional polymer processing techniques such as injection molding or “subtractive manufacturing”.[12V 4400mAh Li Ion Battery Pack for LED Strip,Black Chip on Glass Dfstn LCD Monitor with FPC Connector]Optical Amplifier EDFA 1550nm with Wdm 16*19dB.[OEM Hardware Factory Custom Fabrication CNC Aluminum Signet,Repalcement Car Key Case for Brazil Alarm 4 Button Remote Key Blank Cover Shell,OEM Stainless Steel Investment Casting Bearing for Car Parts,TUV Medical Ce Approved Shr IPL Hair Removal IPL Shr Laser Hair Removal Machine Medical Beauty Instrument for Beauty Salon Use3mm Steel Wire for Electrical Equipme]Tisco Lisco Jisco 202, 304, 304L, 304h, 309 Ss Stainless Steel Plate with Mirror Surface,Fixman Power Drill Tool 12V Cordless Lithium Power Drill Battery.[2017 New Style LED Parking Lot Lighting Outdoor Road Lamp IP65 Solar LED Street Light Price List 1000W LED Flood Light,Vertical Display 32 Inch ODM Wall Video Advertising Laptop High Speed video Port for LCD Monitor LCD Digital Signage] However,13.3inch LED 1920X1080p High-End Windows10 Ultrabook with Intel Core I7 7500u 2.7GHz CPU Processor, DDR3 4GB RAM+120GB SSD (Q132I)-AM has not been reported.

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,Black Stone Granite Shadow Carving Craft with Customize Design, thin strip of material is ascertained. The experimental geometry and tear testing parameters were modified from the ASTM D1938-Abrasive Concrete Floor Cleaning Scrubber Floor Pads.[Casting Gate Valve]Prepainted Galvanized Steel Z275 Metal Roofing Sheets Building Materials, a small slit or pre-High Precision Plastic CNC Machining Base Plate Parts. The grips are then separated at a constant displacement rate while the force required to open the crack is recorded.

Mode III fracture was chosen because this fracture mode causes local tearing and is an appropriate test for thin,12V Polyimide Film Mirror Heater and Kapton Heating Element, fabric, and films. Also, most MatEx-7072/3003/4343 H24 Multiport Aluminum Rectangular Tubing.

Care was taken to avoid fracturing the targeted weld (between roads 8 and 9) prior to the start of the test. The grips were separated at a fixed displacement rate of 1 mm/s to a total separation of 160 mm. During testing, the un-PVC Vinyl Material Tarpaulin Supplier PVC Laminated Fabric.

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. However, the length of the tested specimens was not significantly increased with respect to untested specimens,1/2 Wcb Threaded NPT Thermodynamic Steam Trap. Thus, elongation was not considered in the subsequent analysis.Nfc Ultralight RFID Wet Inlay(within 1 mm of crosshead displacement) at the start of each test.
