Design of a 3D Printer based on Fused Deposition Modeling
As my senior design project, my team (of 4) and I designed and fabricated a Cartesian X-Y frame 3D printer based on Fused Deposition Modeling Principle. This project received an award in the form of sponsorship worth INR 50000 from the department of Mechanical Engineering. The success of this project also gave an impetus to additive manufacturing projects and rising interest in the domain among students at Sardar Patel College of Engineering.
CONCEPT:
Concept model was developed in CATIA v5 after careful consideration of scope and requirements from the printer.

DETAILED DESIGN:
Strength of the parts were calculated using MS Excel and engineering principles. Major load bearing members such as travel shafts and fixtures were analyzed using FEA in ANSYS Workbench.
CONTROL SYSTEM:
Arduino Mega based control board - RAMPS was used to integrate all the electronics and control from a central processing unit. Repetier host, an open source 3D printing firmware was utilized to implement the necessary printer motions.

JARVIS 3D PRINTER:
The 3D printer was fabricated using using various manufacturing techniques such as Lathe turning, milling, grinding and polishing. Entire was built under total expense of INR 35000. The printer was named JARVIS inspired by Marvel's Iron Man AI assistant.
