[Lab] Lab Digest, Vol 35, Issue 13

[Joshua Mark]

I don't think I quite have this lab mail list reply thing down yet. Should
I CC lab at artengine.ca for each reply I want to be a part of the thread?

Upon more thought, I've come up with 2 variations on a theme. One would use
the fancy accurate 3D printer to build a component scaffold to hold the
balanced armature drivers, the 3 way passive crossover and any other guts
of the in-ear monitor. This would then be dropped into the gel mold just
after pouring the flexible silicone and just before pouring the acrylic
(see this <http://engt.co/UqkMa7> for context). The scaffold would be
printed with ABS and wax such that after the acrylic is set, the device
could be heated, and the wax would pour out the ear canal, opening
the channel to each driver. It's complicated and heating the device might
damage it. However, if it works, it removes a lot of finicky work getting
the components into the acrylic cast.

The second is much easier. Build a model for a normal ear bud with space
for the drivers and components. Print it in 2 "mate-able" pieces. Insert
the components and just glue them together. Then use a normal ear bud tip
or do the Collin's Lab gooey ear kit thing. This is *so* much easier and
should have similar results.

Thoughts? Thanks for the input guys!
