Dear All:

We are doing a prospective study about the employment and the
developments taking place in the use of RP Technologies in Medicine,
medical devices, and in general in biomaterials. If any of you is
WORKING in this subjects (or doing RESEARCH for new RP related
developments in medicine and biomat) we would like to include your
reference in the study. We cannot offer you a copy of the report (it is
paid by the Sanitary local institution, so they are the owners), but we
will post in this forum the compiled responses received.

Mr. Perez Perez Miguel Angel,
I am very much happy after watching such type of mail in the list
please include my name in this reference "Manak Lal Jain" I am doing my
P.hD. at IIT Kanpur (India) and my area of working is RP application to
Biomedical engineering and presently I am in a process of completing the
cource work for the needful.
I am also requesting to you that please mail me a copy of all such
related mail after collecting it which will be helpful for me .
Thanking you=20

Dear MR Perez,

We here at SIRIM Rapid Prototyping Services have just started this year
venturing into the field of medical Model building using our SLA
We have todate produce 2 skulls for maxilio facial surgery and 1 full
for the local medical univeristy as a demo set.

We are hoping to see this industry grow.

We hope we could be of help and share common information.

Thank you

Dear Miguel,
We are involved in RP for medicine. I will finish my PhD thesis very
soon (in fact I have to finish it for the end of this month). It
concerns new biodegradable implants for lumbar fusion. We have made some
=AB weight -bearing =BB macroporous scaffold with controlled porosity in =
using an inkjet method. These implants are made out of hydroxyapatite
cement. We published a paper on these cements (fabrication protocol and
characterization methodology that can be used with anisotropic
3D-controlled scaffold) ( !!! not the well-known non-degradable
hydroxyapatite sintered ceramic) :=20

Dear Mr. Perez,=20
you also should check Invisalign's process of building teeth braces
(<http://www.invisalign.com/>: SLA moulds and vacuum casted appliances)
and Materialise's process of builin drilling guides via SLA for dental
implants (<http://www.materialise.be/>, look for SurgiCase). Beside
that, several dental companies use similar processes (scanning, modeling
and automated, custom-made manufacturing) by finally CNC milling
ceramics. You might check Sirona, 3M/ESPE, Nobel Biocare, Degussa, or
DCS Dental.=20
I would be very interested in the outcome of your research.=20

Dear Miguel,
We have been working commercially and conducting internationally
research into the application of Rapid Prototyping in medicine for the
three years. We can be contacted at the address below.
We would welcome approaches for commercial or research collaboration
across Europe.

Dear Miguel Angel P=E9rez,

to get a good overview about the application of RPT in Medicine I=20
can strongly recommend you come to the PHIDIAS Global=20
Workshop which is held in conjunction with CAS 2001 (computer=20
assited surgery and rapid prototyping in medicine) in Nuremberg=20

This workshop will give you up to the minute information on RPT in=20
medicne including latest developments. Details can be found at=20

One more thing I should mention is that the workshop will start=20
this thursday, so you need to hurry.

Looking forward to see you in Nuremberg
