The document outlines the technical specifications for creating a 3D scale miniature model of the Rail Wheel Plant in Bela through 3D printing technology. The model is to be 11x9 feet at a scale of 1:500 and printed in four parts using nylon material. It will include detailed representations of the plant area, buildings, roads, ponds, and more. The model will be painted using non-toxic acrylic paints and have laser lighting effects to identify different areas. It will be placed on a wooden base and acrylic case with a foldable stainless steel display stand.

1. SCOPE 1
Technical parameters/Specifications of the work for preparation and supply of
3-D scale miniature Model for the Rail Wheel Plant Bela through 3-D Printing
technology are given as under:
(1) 3D model creation. 3D CAD version of the whole plant covering all
landscape within its boundary with all the details like various shops in the
plant area, administrative building , roads, ponds, garden, colony,,club etc.
(2) Making of the model (Physical Model) | Technology: 3D Printing (Selective
Laser Sintering), Material: Nylon (PA2200). High precision, detail and
smooth surface finish.
(3) Model Dimensions: 11*9 Feet, scale- 1:500, Height as per the scale of the
model , model should be prepared in four equal parts for ease of assembly
and transportation.
(4) Post processing and painting of the model
(a) Model should be coloured using non-toxic acrylic paints to
actual colour.
(b)Water based paint should be used for appearance of the
colour of the model.
(5) Visual marking and miniature models of structures and architectures within
the plant and colony area.
(6) Laser lighting effects to be effectively used for identification of different
parts of the model.
(7) Wooden/acrylic base of size and transparent/clear acrylic case of suitable
size to accommodate the final model.
(8) The model should also include the model base / wooden table with glass
coverings to accommodate the final model.
(9) Fabrication of foldable stand of non corrosive stainless steel frame (of size
proportionate to actual model size) on which model along with base will be
mounted for display.
(10) Handling , transportation and assembly to model roomof Rail wheel
plant Bela
(11) Final demonstration of model at RWP Bela
