along with machine.

5 The machine capability to process the following materials

6 Stainless Steels as per DIN

7 Titanium based Alloy Ti-6Al-4V As per MP-150m

8 Cobalt-based alloy CoCr etc.

9 Aluminum alloy AlSi10Mg As per MP-150m

10 Machine will be able to handle metal powders mentioned from 3rd party metal powder

manufacturers as well. 11 MATERIAL TEST REPORTS specify the qualied materials and its material

properties by attaching material technical data sheets. Software material build parameters.

12 Laser Safety : The machine will meet the requirements of laser safety as per EU

13 Operating Gas :The machine will be able to operate both in Nitrogen and Argon modes.

With regard to safety against oxygen, system able to process with 0.1% oxygen.

Build Parameters :

1 Achievable part accuracy +/- 50 micron As per ISO 2768-1/ DIN or Similar

2 Layer Thickness range cover 20 microns to 60 microns or wider

3 Editable parameters provided to vary scan speed, laser power, spot size, trace

spacing, oset to original contour along with the supply.

4 Volume build rate in the range of 15 cm3 / hr. to 20cm3/hr. demonstrated on asked .

5 Capability to Build Parts

6 Capability of manufacturing wall thickness of 0.15 mm

7 Capable of printing minimum diameter of 0.1 mm

8 Ultrasonic Sieving systems which can operate in reactive and non-reactive material

in inert environment. Sieve sizes applicable to materials as referred in

Clauses 3.5.1 to 3.5.5 included in the supply.

9 The machine will be all the necessary modules / containers for sieving , extraction

of the materials handled.

Technology:

1 The build area temperature will be controlled to ensure repeatability of parameters

on the machine, especially when a large /continuous production is resorted to. Along with

Ergonomic Handling systems with following features,

a) Suitable safe system for removing and transporting building platforms.

b) Cleaning - Since during building a lot of condensates is sucked from the build area into

the lter, the system automated lter cleaning. Suitable vacuum cleaner.

Notes:

I. In case of build and support material are dierent, separate bays for the materials.

II. For reducing residual stresses, provision made for pre-heating of build material

Software (AI Inbuilt):

1 Compatible software with user interface routines will be Provided . It cover the building

process and include repair, cutting or scaling of 3D structures. If the part is to be separated from

the building platform, e.g. typically in Direct Part applications, a support structure will be Provided

2 The CAD data are normally converted into the STL format in which the part geometry is

approximated by a network of triangles. However, various software packages permitted /

formats such as STL,3MF,OBJ,PLY etc..

3 STL verication for correction of ipped normal and overlap incidences

4 Automatic generation of support structures

5 Scaling (linear and non-linear) and resizing

6 Automatic build time estimation

7 Interface for visualizing layer data.

8 Software will be able to generate a G-Code and the System needs to be able to read &

process the Code.

9 The machine software inbuilt tool & capability for third-party material parameter

development. All software licenses to be perpetual.

10 The Software will be additional 20 users lic. for oine Training to student / professionals .

All software licenses to be perpetual.

11 Software will be integrated with Smart and automated generation of design of experiments

DoEs models for the most critical process parameters.

12 Software give Automatic part density calculation using microscopic images and smart

image processing for development of new alloys parameters.

13 Computer with Core - i7 (7th generation or latest) of HP / Dell Make
