Covid-19 Face Mask · 模型 199252
Easy to 3D Print Face Mask. The model I have uploaded is not the one shown in the headline picture, but the simpler version of the mask. If you would like to try the 3-filter version, please ask and I will upload. There is also a version that includes for the fitting of a vent pipe, supplying positive pressure air into the mask. These are simple models but if anyone wishes for a production standard design that could be easily moulded, then I could provide if requested. Is an adaptation of previously submitted models used for ventilators but with a change to the inlet, allowing replacement cotton/paper/tissue filters to be fitted using the Cap to secure filter sheets around the periphery of the Mask extension. Filters are placed against the lip with the filters cut +10 to +20mm diameter to that of the outer diameter of the Mask extension. Cap is pushed into position, wiping outer diameter of filters over the lip and along outer diameter of the Mask extension. This secures the filters accordingly and the interference fit helps secure and seal the Cap. Both the Mask and Cap are very easy to print (no support structures needed). Am currently printing in Polypropylene so that the mask incorporates some flexibility around the face and can be used for medical applications. Due to material, steam can be used to sterilise the face mask. So far, print looks very good and stable. Printing using Ultimaker 2+ with white PP, bed temp 100 degrees Celsius and head temp at 220 degrees Celcius. Print speed at 80mm per second with 100% fill. Will upload some pictures when done. Currently testing different "easy to get" filter materials and will be providing details on that too. Clearance between inner diameter of Cap and outer diameter of mask protrusion is 2.5mm, allowing multiple sheets of kitchen towel, fine cloth, dense filter sheets etc. to be fitted. As with all filters, they need changing regularly (every 2 to 4 hours). Wear gloves when changing filters. Disinfect/Steam Face Mask and Cap each time when changing filters. Large intake cap allows larger filter surface area/volume and denser materials. It is important to reduce air flow by introducing larger surface area/volume/density of filter. You do not want small diameter filters as this concentrates collection of moisture, germs and virus, reducing efficiency of filter. Smaller intake sizes also requires more porous filter materials to be used, no good for containing bugs.
