Práctica 5

thingiverse

Welcome to the second module of practice! If you're reading this, it's assumed that you're familiar with concepts like layer height, bottom/top thickness, fil density and print speed. If not, we recommend taking a look at the previous module where these concepts were explained in detail and how to work with them. Practice 5: Layer Fan File to Print: Bridge torture test Cura Parameters: Layer Height: 0.20mm Bottom/Top Thickness (mm): 0.8mm Fil Density: 40% Print Speed (mm/s): 40mm/s Extruder Temperature: 190°C PLA / 210°C ABS (temperature is indicative, follow manufacturer's filament instructions) Bed Hotend Temperature: 60°C PLA / 100°C ABS (previously spray a small amount of laca on the print surface for better results) Support: No Support Type: None Platform Adhesion Type: None Filament: 1.75mm or 3mm, depending on your printer's filament diameter. Flow: 100% Layer Fan: To enable the layer fan, we'll go to the Advanced section, and locate the enable cooling fan parameter. Here we need to activate the square and confirm with the symbol. It is **IMPORTANT** that our 3D printer has a fan, otherwise move directly to the next practice or think about adding this accessory. What it allows us is to prevent layer drops, in other words, when printing structures without support, the plastic does not cool down quickly enough, falls, and creates small scratches, causing the piece to lose quality and aesthetic. The exercise consists of printing the bridge piece with and without fan activated and appreciate the differences. Once we have the two pieces, make a third print lowering a little the temperature and print again. If everything goes as it should be, the parts will improve in quality.
