The model consists of five main components, each serving a crucial role in the assembly process. These parts include the TPU tip and wire cover, the ABS fan and exhaust tube, and the PETG tube. Due to printer limitations, the chosen material is PLA, reflected in the .gcode file settings.Assembly Steps:Attach the Exhaust:Connect the exhaust to the longer end of the tube.    2. Fan Placement:Insert the fan into the short end of the tube, placing the axle end first.     3. Cap Sealing:Place the tip onto the short side to seal the cap.    4. Motor Connection:Connect the fan's axle to a motor.     5. Wire Cover Installation:Position the wire cover over any wires that control the main tube's guiding motors.Functional Overview: The assembled model serves as a controllable tube capable of pumping blood from the left ventricle into the aorta, facilitating circulation throughout the body. The surgical procedure is efficient, with effects lasting up to 72 hours. This simplified and printable version draws inspiration from the impella design.Print Details:Print Size: Approximately 66 mm x 40 mm x 23 mm.Final Product Size: Around 80 mm x 7.5 mm x 8 mm.Print Time: Approximately 40 minutes, dependent on print speed.Support Removal: 2-5 minutes.Assembly Time: 2-3 minutes.Printing Specifications:Printer Used: Creality Ender 3.Infill: 15% with a fill pattern of triangles for optimal support and faster printing.Brim: Not used; supports employed for stability.Material Cost: Less than 2 grams of plastic, costing around $0.30 (prices vary based on material).Software Used:Design: TinkerCAD.Slicing: PrusaSlicer 2.6.1.Conclusion: This innovative and cost-effective model is a testament to the potential of 3D printing in the medical field. The combination of efficient printing, low material usage, and affordability makes it a practical solution for temporary cardiac support, extending life for up to 72 hours.THANKS FOR READING!Contact Name: Mohammad NdioubnaneSchool: Crescent View AcademyBestHub: Rocky Mountain BEST (Denver)
