        We at the Rapid Prototyping Cell of Indian Institute of
Technology-Bombay are organising a three day workshop on rapid
prototyping, soft tooling and related CAD/CAM technology at the Rapid
Prototytping Cell of the Indian Institute of Technology-Bombay. The
present workshop aims at disseminating the latest developments in this
field to the various sectors of the Indian industry. Please find the

Dear sir/ madam:

    Subject: Workshop on Rapid Prototyping & Tooling (RP&T)

    We are pleased to inform you that we have scheduled a "3 Day
Workshop on Rapid Prototyping & Tooling (RP&T)" at Industrial
Design Centre of IIT Bombay during February 6-8, 1998. The
outline of this workshop is as follows:

- February 6, 1998: Rapid Prototyping
                      Introduction to RP technologies, its
                      impact on time compression of product
                      development, presentations on various RP

- February 7, 1998: CAD/CAM/CAE Software for RP&T
                      Solid modeling software, file formats for
                      RP, RP software for slicing, orientation
                      determination etc., presentation of popular
                      CAD/CAM/CAE packages.

- February 8, 1998: Rapid Tooling
                      Manufacture of tools and patterns rapidly
                      using RP processes, various routes to
                      manufacture of tools rapidly from the
                      conventional Rapid Prototypes such as
                      electro-forming, metal spraying etc.,
                      presentations on popular RT technologies.

    We had conducted two such workshops earlier which had over-
whelming response from the industries across the country. We are
organizing it this time in a grander manner and on a larger scale.

    I have given the details of this workshop below. This is a
special request to you, the ex-IDC'an, from Prof. V.P. Bapat and
and me to see that the intimation of this workshop reaches all
concerned people in your organization so that as many of you and
your colleagues attend it.

    You will find that this technology of RP&T is going to revo-
lutionize the future manufacturing which is characterised by its
agility and its ability to support mass cutomization economically.
Please join and help us in disseminating this knowledge in Indian

    With many thanks and warm regards,

                                         Yours sincerely,

Rapid Prototyping Cell (RPCell) located in the Industrial Design
Centre of IIT Bombay was established in 1995 as part of the
Technology Development Missions on Integrated Design and
Competitive Manufacture, sponsored by the Govt. of India and an
industry consortium. The facility comprises a Stratasys FDM 1650
RP machine, two Silicon Graphics Indy R5000 workstations and
relevant CAD/CAM software for design, analysis and manufacture
of discrete products and the tooling.

The RPCell facilities are currently utilized for technology
demonstrations, industry projects and research. Coupled with the
existing facilities in IDC and the experience of the faculty
members in design consultancy to over 500 companies, RPCell can
now offer complete solutions integrating concept design, stress
analysis, assembly modeling, prototyping, tool design, tool
fabrication and process optimization.

An inter-disciplinary team of faculty members from Industrial
Design, Mechanical Engineering and Metallurgy is currently
engaged in various research and development projects. These
include techniques for producing soft tooling, tool design
software and optimization of RP process. These projects aim to
explore and exploit the RP&T technologies for the benefit of the
Indian industry.


The first Rapid Prototyping (RP) machine was introduced in 1989
as a designer's visualization tool. In less than ten years, RP
technologies have revolutionized the way consumer products are
designed and manufactured. Recent developments in Rapid Tooling
(RT) techniques have demonstrated ways to manufacture die and
mould cavities faster and cheaper justifying the use of casting
and moulding processes even for small lot production. By
realizing the components layer-by-layer, RP techniques enable
the manufacture of complex shapes to be produced directly from
their computer models within a few hours; no part-specific
tooling or machining is required.

Several RP technologies are now available. These include

Stereolithography (SLA),
Fused Deposition Modeling (FDM),
Solid Ground Curing (SGC),
Laminated Object Manufacture (LOM),
Selective Laser Sintering (SLS),
3D Printing (3DP) and

These produce models in a variety of materials. These rapid
prototypes can be used as masters for copy milling; and patterns
for sand casting, epoxy shell moulding, silicon rubber moulding or
investment casting. Other routes to obtain tooling from the rapid
prototypes such as metal spray and electroforming also are

Rapid prototypes are useful for concept verification,
performance testing, stress analysis, wind tunnel testing,
assembly interference checks, artificial limbs, market research
and tender offers. A rapidly growing number of companies
worldwide have dramatically reduced the concept to market lead
time, slashed overall costs and improved the quality assurance
by integrating rapid prototyping and tooling techniques into
their design and manufacturing operation.


The present Workshop on Rapid Prototyping & Tooling is to
disseminate the latest developments in Rapid Ptototyping
&Tooling technologies and demonstrate their applications to
various sectors of Indian industry. It will be conducted by a
team of experts from IITs and executives from leading RP&T
companies. It is designed for senior executives, product
managers, R&D personnel and consultants in the automobile,
consumer, defense, engineering, medical, sports and
entertainment sectors and tooling companies catering to casting,
molding and sheet metal forming processes.

Participants will get a first hand exposure to various RP&T
techniques, different routes to rapid production of tooling and
supporting technologies such as solid modelling. Industry
presentations will provide an appreciation of technology
capabilities, limitations and applications. Course material
will provide all the necessary details and further references.
This Workshop will be held at Industrial Design Centre of IIT
Bombay, Powai, during February 6-8, 1998 from 9:00AM to 5:30PM.
The schedule is as follows:

Feb. 6: Rapid Prototyping Technologies

Feb. 7: CAD/CAM/CAE Software for RP&T

Feb. 8: Rapid Tooling Technologies.

Each day will begin with lectures on state-of-the-arts in the
respective topic by experts followed by a panel discussion and
presentations by the vendors.


Interested participants may register for the workshop by
completing and mailing the form to the Convenor along with a demand draft
of Rs. 5,000 (US$200 in case of international participants) as the
registration fee. The fee covers admission to all lecture sessions and
demos, course material, lunch and tea. If the participants need
accomodation in our Guest House, they must contact early so that we shall
try for the same. However, the availability is not guaranteed. We
shall intimate the participants if Guest House is available; otherwise,
they shall make their own arrangements.

Organizations that sponsor 10 or more participants will be given
20% discount in registration fee. Please send your registration
form along with the fee preferably on or before Jan. 31, 1998.

Advance registration may be made through email as well. However,
if the course fee is not paid in time, the seat may be offered to
