3D printed Face Shield by An Duong - Let's fight Covid-19 together!
What is this?
This is a 3D printed Face Shield I designed as part of my ‘Fight Covid-19 with An Duong‘ package
* I designed this face shield based on a design that I saw on GradCAD – LINK
To help fight Covid-19 in the UK, I’ve been producing and donating 3D printed face shields and ears savers to the frontline NHS staff in the UK
Since I shared some videos with me 3D printing Face Shields on LinkedIn, many people have reached out and asked if they could print this design in stack on their single-extrusion printers. The answer is YES. If you want to print this stackable design on your printer to maximise productivity, please download the STLs via: LINK. I already stacked them in batches of 3, 5, 10, 15 … up to 40 – so, simply pick what your printer can handle, load the relevant STL in your slicer, get your own g-code, and start printing!
Recommended printing settings
– No support (please do NOT use any support – that’s because there is a 0.2mm gap between each part)
– No infill
– 0.2mm layer height
– 2 walls (I use a 0.4mm nozzle – hence, the wall thickness is 0.8mm)
– 3 layers top & bottom (if the parts get damaged when you separate them afterwards then increase this to 4 or 5)
– Brim on the first part to ensure good adhesion to build plate (Optional)
– Print speed: 70mm/s
After printing is done, you should be able to separate the parts easily (either by hand or a plier) and no post-processing should be required (since there is no support material to remove). I suggest you start with a small batch of 3 (or 5) first to see if this method works well on your printer, if it does, then you can max out the Z.
To make this Face Shield, apart from the 3D printed headset, you’ll need to purchase some standard stuff:
1, A standard 2-hole punch: there are lots of these on Amazon (e.g. LINK). I got mine from Wilko for just £2.5
The 2-hole punch will be used to punch 4 holes on the A4 acetate sheet.
You’ll need to set to A6 on the punch, load the sheet, punch 2 holes on one side, then flip the sheet and punch another 2 holes on the other side. You should now have 4 holes that are aligned to the 4 pegs on the 3D printed headset.
2, A4 clear sheets: You can purchase any A4 acetate sheets or binding covers on Amazon. Make sure that you purchase the ‘clear‘ one, not ‘frost‘. Any thickness between 200 micron to 500 micron is fine. The one I normally use is: LINK
3, Elastic band: You can easily purchase these on-line or at any shops. The one I normally use can be purchased from Wilko (LINK) but any other type of elastic band should be fine.
This face shield was designed for use during the COVID-19 outbreak. It is a development product and therefore does not comply with EU PPE Regulations and does not have a CE mark. The designer of this face shield is not experienced or expert in producing equipment of this type and is therefore unable to give any assurances as to its quality or efficacy.
