Aegis 2 - Face Shield

thingiverse

This is a detailed guide for creating face shields using 3D printing, specifically designed to help medical front liners during the COVID-19 pandemic. The guide provides information on various designs, materials, and printing settings that can be used to create comfortable and durable face shields. Here are the key points from the guide: **Designs:** * **aegis-max**: full-length temples that can be used without elastics * **aegis-fold**: foldable temples that can print without supports and have a small footprint in the print bed * **aegis-flex**: uses printable clip-on temples along with a hook, providing flexibility and comfort **Materials:** * Acetate sheet (A4) or any rigid plastic material (100-300 microns tested) **Printing Tips:** * Print on PLA for flexibility and to avoid warping * Use ABS for durability, but address bed adhesion issues * Calibrate your printer before printing * Share settings using Simplify 3D or Cura for optimal print time **Important Settings:** * Layers: * Layer height: 0.30 mm * Top solid layer: 3 * Bottom solid layer: 2 * Outline/Perimeter shells: 1 * Speed: * Default printing speed: 70 mm/s * X/Y axis movement speed: 80 mm/s * Outline underspeed: 60% * Infill underspeed: 80% * Extruder: * Nozzle diameter: 0.40 mm * Extrusion multiplier (Simplify3D): 1.30 * Top/Bottom extrusion multiplier (Cura): 130% * Extrusion width: 0.80 mm (IMPORTANT) **Objectives:** * Comfortable for extended wear * Non-reliant on elastics * Low cost * Fast printing * Printable on small 3D printer beds * Easy assembly and no post-processing needed Overall, this guide provides a comprehensive approach to creating face shields using 3D printing, focusing on comfort, durability, and ease of use.
