Mask 3D NanoHack Improved (MassProductionVersion)

thingiverse

Hello everyone. I made an improvement to this mask: http://copper3d.com/hackthepandemic/ (mainly for fast production) Improvements so far: 1. No text on the mask (faster to print) 2. A helper for screwing in 3. More airflow with a grid 4. Thinner construction (faster to print) I printed it using: Temperature: 200 Deg C° Layer height: 0.3mm Speed: 60mm/s I recommend this new mask: https://cults3d.com/en/3d-model/gadget/mask-3d-nanohack-2-0 (it's a new improved version) ---------------------------------------------------------------------------------------- The following text is recommended: http://copper3d.com/hackthepandemic/ (you can find the original here) NanoHack NanoHack Mask is designed to offer protection from airborne particles and prevent spreading liquid contaminating the airways. Published data has shown that the filtration materials used by NanoHack achieve a filtration efficiency of 96.4% for microorganisms of 1 micron and 89.5% for microorganisms of 0.02 microns. According to the U.S. Food and Drug Administration, surgical masks do not provide complete protection from germs and other contaminants due to their loose fit. Surgical masks are single-use devices that must be safely disposed of. The Centers for Disease Control and Prevention recommends placing these items in a plastic bag and putting them in the trash, then washing your hands after handling the used mask. Previous research has indicated that high viral loads remaining in surgical masks and respirators can be a source of viral transmission to both the person wearing the mask or respirator and others. This may happen when healthcare workers touch their mask and fail to wash their hands properly or when they dispose of the mask without proper safe disposal precautions. NanoHack Mask uses a recyclable and biocompatible polymer containing a copper nanocomposite that has shown antimicrobial properties and can deactivate viruses. 3D Printing Specifications: Our printing specifications will result in fused layers, stopping even water molecules that are 0.000282 µm. We recommend a minimum wall thickness of 1.7 mm, which will result in three extrusions side by side producing a double seal. We also recommend adjusting the slicer settings to decrease print speed and increase extrusion multiplier. The specific settings for the slicer software are as follows: • Layers: Layer height 0.2mm, First layer height: 0.25mm, Perimeters: 2, Avoid crossing perimeters: X, Eternal Perimeters first: X, Start end overlap: 140%, Merge overlapping lines: X, Expand thin walls: X, Top solid layers: 9, Bottom solid layers: 9, Infill Fill density: 100%, Infill type: lines starting angle: 0, Infill overlap: 0.9mm, Fill thin gaps: X, Speed infill: 20mm/s, Top solid infill: 20mm/s, raft: 100%, inside perimeters: 20mm/s, outside perimeters: 20mm/s, Support material: 20mm/s, bridges: 25mm/s, Travel: 130mm/s, First layer speed: 20mm/s • Filament: PLACTIVETM: 1.75mm • Temperatures: Extruder temperature: 233 Deg C°, Extruder wipe temperature: 0 Deg C° • Retraction: Speed: 70mm/s • Extrusion: Extrusion multiplier: 1.5, First layer: 160%, Outside perimeters: 160% • Printer: Any desktop 3D printer that allows these settings Copper3D Inc.
