An in-depth guide to 3D printing protective face shields – helping to combat the effects of COVID-19.
A lot of 3D printing service bureaus will be seeing a steep decline in new B2B enquiries due to business shutdowns. Should this stop you maximising your printing capabilities? No! Using the files in the link provided we can help combat the effects of COVID-19 to help support, critical essential workers on the front line.
These specific face shields are being created in collaboration with Solid Print 3D in order get get vital PPE to medical professionals across the U.K.
We’re using the Prusa designed face shield, which can be downloaded and rapid prototyped from the link below:
First step is to prepare the file, Prusa in their latest file version (RC3) have included a stack able (4 units) which is perfect for leaving during lights-out operations.
The Creality Ender 3 can fit 8 masks printing at once, however other printers maybe able to handle more or less.
We’re printing all these parts using Filamentive recycled PLA. As the face shield is single-use, this material was the perfect choice due to its cost, ease and environmental impact (biodegradable).
We recommend the following print settings to achieve the best quality out of your PLA filament (may vary dependent on your filament brand):
Print speed – 90mm/s
Outer perimeter – 70mm/s
Nozzle temperature – 190C
Bed temperature – 60C
Infill – 20%
Layer height – 0.2mm
Once the parts are complete, you must remove these as soon as they’re finished to reduce the risk of contamination. Safety should be the main concern and we’ve listed a few tools that should be used when removing parts.

Store the parts immediately in a sealable bag.
It’s of up most importance to inform the end user of your 3D printing environment and the precautions you’re taking as an individual or a business to ensure the parts are being kept as clean as possible.
There is a debate at the moment on how long the bacteria remains on different surfaces, but most sources state 2 – 3 days for plastic. Ideally parts should be held for 2 – 3 days once packaged, this was you’ll greatly reduce the risk of transmission.
Each bag should be marked / labelled with the following information to ensure full traceability:
Each mask is made up of the following:
For the elastic band component, we sourced this from online haberdasheries who sold this as 1″ (25mm) wide elastic material.
