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
=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)
Visor Frame material PLA (we manufacture this but any PLA would be suitable)
or this Antbacterial material:
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.
The 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.
3d print works PLA
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.
