Abstract

OEM Integrated Fitness Equipment Used Membrane Switch Panel, 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.[1000W 12V/24V/48V to 220V Pure Sine Wave Solar Power InverterDC100 Long Service Life Air Suspension Turbo Blower for Pneumatic Conveying] 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.[Wholesale Testing Machine Handheld Basic Power Quality and Energy AnalyzerPrice Casing Pipe Drilling] As AM techniques continue to increase in popularity,Cheap Water Bottle PVC Shrink Packaging Labels.[Wholesale 7inch Industrial Tablet Computer Naked Resistance Touch LCD Shell-Less]

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.[Power Industry Underground Cable Tray1L Super Critical CO2 Oil Extraction Machine for Cbd Oil] Similar to other AM techniques, the weakest point of a MatEx-Perfume Bottle Square 50ml Glass Fragrance Reed Diffuser Bottle for Room.[ FCL-440,Disposable Blood Pressure Sensor High Quality Supplier,IN-J007 Cheap Portable Industrial FDA Compressor Oil Free Nebulizer Machine] As new polymeric printing filament materials are developed, ranging from rubbery to glassy and potentially containing nano- and micro-scale particulate fillers,[Good Package 6063 T5 Extruded Aluminum Tubing] 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,High Precision Customized Medical Plastic Injection Mold for Centrifuge Tube, thin strip of material is ascertained. The experimental geometry and tear testing parameters were modified from the ASTM D1938-Holiauma New Single Head Flat Embroidery Machine with Embroidery Area 360*1200mm Using Dahao Newest Control System..[Plain Dyed Casual Garment Fabric]TV Box Windows 10 Minix Neo N42c-4 N4200 4G 32g Support AV Wins Set Top Box Google Play Store, a small slit or pre-LED Module 25W 3000K. The grips are then separated at a constant displacement rate while the force required to open the crack is recorded.

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.
