Ref: Masks. Teach deaf ppl has become very difficult because deaf and profoundly hard of hearing ppl read lips. Can these masks be produced using clear material?

@bockenfels this is an interesting issue. While we have been tinkering with the idea of voice modules for ease of speech, and emoji mood screens, mouth visibility hasn't crossed our thoughts. There are "clear" print filaments, but most of them turn our more translucent rather than optical clear. There is more advanced 3D print technology that may give you clarity but it is more of an industrial level of manufacturing. We are very open to innovative ideas, maybe adding a camera and a screen would be a solution for this, but not as passive as a see-thru membrane.

I have no capability or capacity or the intellect to pursue...I am purely an idea guys who thinks of or observes problems and reaches out to doers who may have the solution...I am happy to give you food for thought.

Hi everyone. My name is Carlos. First of all, kudos to the JPL team for this wonderful effort. I am a former product designer at MakerBot so I have a bit of 3D printing experience. Although I don't have access to any printers myself, I will try to see if I can get some prints made through some of my contacts.

@bockenfels: good point about the ability to read lips! Reminded me of a recent article where a college student came up with a low-tech solution. However, as @ericdcontreras pointed out, 'clear' materials are often translucent at best, unless you're dealing with higher-end printers. Nonetheless, I think this is an important edge case, and should be considered.

@bockenfels @graceturing check out some of the neat things that are on the works for the hard of hearing @bockenfels sorry I forgot to tag you on this earlier. We are on the ideas issue section of this forum.

Thought: 3D Print mask that would take some sort of off-the-shelf clear polycarbonate CTGXT AF  coated sheet with anti-fog properties on one side and mar resistance on the other side. I would love to see a viable connection with these communities who have lost a vital piece of their human connection. Thank you all for your skill stacks and the possibilty of success.

Hi Guys,

Jase here from ShieldsUp NZ (https://shieldsup.org.nz/), we recently meet with Glen in New Zealand at our workshop and had a brief Facetime with Tom Soderstrom. Tom was excited and impressed that we had printed your design and requested that we provide some feedback to you. After reading through Git and analysing each of your designs we have printed and tested the Performance model with integrated filler and generally think the design is excellent, both fit and function!! Printed with TPU and PLA using an Ultimaker S5 and everything fits together nicely.

A few thoughts I had while printing and playing around was that the PLA filler parts (Filter_L_Base-800 & Filter_L_Cover-Res) are designed in such away that they are not very printer friendly, requiring what I would consider to be an excessive amount of retraction as well has containing many small elements that are rather brittle once printed. The tolerances and fit of the parts are great but I feel there is room to improve the design for better '3D printability' to produce a stronger more easily printable part that will hold up better to cleaning and reuse over time with out impacting air flow.

A further thought I had which resulted from the success we have had with ShieldsUp (manufactured 18,000 face shields in 7 weeks) is that we used 'stacked' designs, intentionally designing the parts in such a way that they can be printed in a stack of 10 x at a time and separated by hand after the print is complete allowing for maximum up time and limited user interaction. I feel at least the 'filter base' could be designed to be stackable. Just a thought really :)

Keep up the Amazing work!!
