This Visor was designed in consultation with our local Hospital Clinicians. The advantages of this design over what they are using at present are: (Materials & Print settings are at the end)=uses Antibacterial filament https://3d-print-works.com/products/antibacterial-abs-3d-printing-filament?ls=en-GB&variant=32134137348176=More robust=Re usable if sterilised using chemicals see data sheet.=Unique clinch and pin design holds face shield secure to frame=Clean design reduces snagging on clinicians hats and other articles of equipment worn on the head=quick to produce in 3D printers=Uses standard 140 - 200 micron A4 clear PVC stationary binder sheets for the shield,=Binder sheets inexpensive and bought from any stationary store or Amazon=standard 4 or 2 stationary hole punches can be used to make holes in the PVC sheets see drawing for spacing= Shield easily attached to frame by push on design no clips are protruding parts=Two sizes available to print but larger one will fit all with use of a rubber band at the back (holes included for attachment) MaterialsVisor Frame material PLA (we manufacture this but any PLA would be suitable) https://3d-print-works.com/products/pla-1-75mm-elefilament-3d-printer-filament?ls=en-GB&variant=38427680777or this Antbacterial material:https://3d-print-works.com/products/antibacterial-abs-3d-printing-filament?ls=en-GB&variant=32134137348176 Visor shield is A4 clear PVC stationary binders from any stationary shop or Amazon requires 4 holes see drawing these can be made with a standard stationary 2 or 4 hope punch. Machine settingsThe machines we used were Creality 10 mechanics with modified control circuit- 32 bit boards running marlin 2 and V6 Volcano heads, 0.4 nozzle 90mm/s but I think any printer could make it.230 C hotend temp 0% infill 3 shells no supports, run time approx 1 hr30, approx 35gram print also See enclosed factory settings for Mk7 for simplify. Also I have included files which will run at 32 mins but using a 0.8 nozzle and vase mode see factory setting from simplify. NB the Mk8 files are to help people with smaller printers I have split the the model up for you.Print SettingsRafts: NoSupports: NoResolution: 0.2Infill: 0%Filament brand: 3d print works PLAFilament material: PLANotes: I have enclosed factory files from simplify that will give you the setting for different nozzle sizes 0.4 and 0.8 if you use the 0.8 then its vase mode this give a quick print approx 30 mins versus over an hour with a 0.4 nozzle. The small pins that hold the shield in place do not print out as well with a 0.8 nozzle but they still work even if they look a bit rough.
