Investigations for Mechanical Properties of Nylon6-SiC-Al2O3 based Feed Stock Filament for Fused Deposition Modelling (FDM)
Introduction
• To develop feed stock filament for FDM with Al 2 O 3 reinforcement as single particle size (SPS), double particle size (DPS), triple particle size (TPS) in Nylon6 matrix
• To investigate the effect of particle size ie, SPS, DPS , TPS on mechanical properties of developed feed stock filament material
• Optimization of process parameters for feed stock filament of FDM, namely : Tensile Strength, Dimensional Accuracy, Young's Modulus, Yield strength, %age elongation
• To develop feed stock filament with hybrid reinforcement (SiC and Al2O3) in Nylon matrix
• To investigate the effect of hybrid solute on properties of developed feed stock filament material (like: tensile strength, percentage elongation, Young modulus etc.)

Achievements
As an outcome of this research project, an alternative feed stock filaments with Al2O3 reinforcements as SPS, DPS
and TPS in Nylon6 matrix have been successfully developed. The empirical relations for mechanical properties
have been successfully developed and counter verified. Finally it is concluded that in-house prepared FDM
feed stock filament with tailor made properties can be successfully used (based upon industrial applications).
Along with this an alternative feed stock filament with hybrid reinforcements as SiC and Al2O3 in Nylon6 matrix has been successfully developed. The MFI of feed stock filaments prepared with SiC and Al2O3 were
comparable to the ABS filament used conventionally in FDM. The mechanical properties (like: Percentage
elongation, Young’s Modulus, Yield strength) have been optimized to increase the application domain FDM.
The empirical relations for mechanical properties have been successfully developed and counter verified. Finally
it is concluded that in-house prepared FDM feed stock filament with tailor made properties can be successfully
used (based upon industrial applications). The outcomes for the present work show feasibility of development
of FDM wire from alternative material. As ABS wire is having limited wear properties so alternative material
can be used to have tailor made properties. This project is in line with the Government of India initiatives of
Make in India as alternative feed stock filament with tailor made mechanical and wear properties have been
developed indigenously (in house) and that too at very low cost. The expected beneficiaries of the project
are FDM consumers specially field engineers/persons involved in development of functional/ non functional
prototypes who have to pay high cost of consumable (in form of spool of wire) to manufacturer (as because the
commercial wire spool is a patented material and it is available at high cost around Rs 24,000/- per spool in
India). The alternative wire spool developed is of around Rs 250-300/- per spool which is much cheaper and can
be used for unlimited rapid tooling applications. This work is major breakthrough in enhancing the application
domain of the FDM process.
