Rapid Manufacturing TechonologiesFrans Burghoorn,
We have a hard rubber (HR100) SL material with an 80A shore hardness and
100% elongation. This material is clear with a slight amber color. The
material is "weatherable", no signs of degradation in lab tests, and is a
urethane acrylite resin. Our customers are currently using this material
and our OC100 polypropylene type material in production environments.

We are currently working on a Mid rubber (MR100) SL material in our
SLA250\30. This material might be more of what you are looking for. It is
clear, has great flexibility and the shore hardness is 50-60A. If you want
more information, I can be contacted by e-mail at jharrison@3de.net or phone
at 954-582-0582.

Dear RP specialists,

In Holland, earpieces for hearing instruments are produced by hand. This
is a labour intensive job, involving casting and hand milling. Now I'm
investigating the possibility of rapid manufacturing these earpieces, and
I'm asking you specialists to bring up some suggestions.

As you may have heard, Siemens Hearing Systems produces shell-type
earpieces for hearing instruments. 3D system's SLS technology is being used.
These earpieces have surface roughness, aren't the best accoustically and do
not look the way the Dutch customer prefers.

I'm looking for a technology to produce nice solid earpieces for
behind-the-ear hearing instruments (mainly sold in Northern Europe). The
earpieces should preferably be transparant and smooth. Currently these
products are made of PMMA, being casted and hand milled.

I have found some information of jetting, SLA and FDM methods. Can you
supply me with information about the (im)possibilities and cost
effectiveness of these or other methods? All of your ideas / producs are
very welcome.

Thanks in advance,
