Hello All,

I have been approached by a Doctor at the Royal Children's Hospital for help in producing personal protective equipment using 3D printers. 

This is through 3D One.

The process involves: 

1. Filling out this form re: your type of printer/s, materials & amount available 


2. 3D One then send you what to print (ie what is most urgently required from your particular printer/s such as Face Shield parts or Ventilator parts). The Face Shield is TGA approved, SLS & MJF are good for the Face Shields and these are the most urgent print file that hospitals are requesting, which is suitable for FDM: https://www.thingiverse.com/thing:4251480

3. We then mail the printed items to 3D One (they are in the process of establishing assembly locations in each State).

4. 3D One then do their quality-assessment (they take full legal responsibility for all items) --> assembly (ie the Face Shield head part is what we print, and they then assemble it to the face shield) --> sterilise --> distribution

Ps in terms of the reimbursement, 3D One are invoicing the hospitals $5 per unit assembled, sterilised and packaged, and passing 3x material cost ($1.50 for the Face Shield) per unit back to all 3D printer operators to cover materials, print costs and postage.

Hi All

I have been thinking on designing a face shield and believe that a laser cutter alone may be a better solution due to the greatly increased speed of production.

I know that ABS is a not suitable for laser cutting due to the fumes produced. Is there a flexible 1.6mm approx firm but flexible plastic sheet available that would be a good substitute? The clear face shield plastic also needs to be sourced. One way to cut this would be using a waterjet. cutter. Using a waterjet you can stack parts say 50mm high that's about 60 sheets of 0.8mm plastic at a time the cost per part will be low. There is normally a sacrificial sheet top and bottom as well.

Any thoughts welcome

Hello hello,

I saw a post somewhere somehow by a Melbourne manufacturer that usually make fish finder visors that they switched to producing face shields ( https://www.berleypro.com/product/face-shield/ ) 
They have been producing visors from a thick piece of foam and the plastic sheet (foam instead of 3d printed plastic).
I wonder what the pros and cons of using adhesive foam would be versus printed PLA (because it sure seems like it would be much quicker)

Waterjets dont work with stacked products, as the extreme pressure gets between the layers and disburbs the stack. A better solution maybe to stamp out with a press, cheaper and faster. The major problem I keep hearing from those making Covid stuff is sourcing the material. Most seems to come from China!
For what is it worth from a toolmaking background.

I beg to differ, See the search link below.

Cutting thin plastic may require a sacrificial sheet top and bottom. Maybe Chipboard? Anyway it can be done.

Hey all,

I am starting to run low on isopropyl alcohol to clean my printer bed, was wondering if anyone knew where to source some. Have done bunnings, big W and office works but to no avail.

Any info would very helpful.

I've bought from these guys before however it's become over 3 times the price I paid for my 5L bottle of 100% IPA.

Others might know other sources. btw, There are 1L bottles for $55, but honestly you're better off getting the 5L bottle.

Kind regards,

Rockby has 1L technical grade isopropyl alcohol for about $23 if still in stock. Not sure of percentage.
