Utility:
The Rapid Prototyping laboratory at NIT Warangal is to provide the students with an active learning environment for fabricating three dimensional (3D) models directly from the computer aided design (CAD) data.  Students use the laboratory to model and fabricate complex shaped objected that are used in the engineering and medical applications.

Lab Coverage:
Modelling and converting CAD models into STL files, Simulation of process parameters using Catalyst software, Fabrication of CAD models using Fused Deposition Modelling (FDM) rapid prototyping (RP) machine, Converting CT/MRI scan data using MIMICS 14.1 Software for Medical application, Fabrication of Bio-models.

Rapid Prototyping Machine

Fused Deposition Modeling (FDM) is a free-form fabrication technology developed by Stratasys®, USA. A plastic filament is unwound from a coil and supplies material to an extrusion nozzle. The nozzle is heated to melt the plastic and has a mechanism which allows the flow of the melted plastic to be turned on and off. The nozzle is mounted to a mechanical stage which can be moved in both horizontal and vertical directions.

Utility:

  • Generating STL files from CAD data
  • Working with STL file errors and correction
  • Simulation of Process parameters
  • Fabrication of Physical models from CAD data
  • Post processing of models

MIMICS 14.1 Software

Mimics is software specially developed by Materialise for medical image processing. Use Mimics for the segmentation of 3D medical images (coming from CT, MRI, microCT, CBCT, Ultrasound, Confocal Microscopy) and the result will be highly accurate 3D models of your patient’s anatomy. Use these patient-specific models for a variety of engineering applications directly in Mimics, or export the 3D models and anatomical landmark points to 3rd party software, like statistical, CAD, or FEA packages.

Utility:

  • Create accurate 3D models from imaging data
  • Accurately measure in 2D and 3D
  • Export 3D models in STL format for additive manufacturing

 

Modules:

  1. Base Module
  2. Import Module
  3. STL+ Module
