3D Printing & Prototyping

Turn ideas into testable prototypes with speed and accuracy.

At Mech Flow Designs, our 3D Printing & Prototyping services help you move quickly from concept to reality. Using advanced 3D printing technology, we create physical models that allow for rapid testing, refinement, and validation. Whether for functional parts, proof-of-concept models, or scaled prototypes, our solutions reduce development time and bring designs closer to production with precision and efficiency.

  • Concept Models Early-stage prototypes to visualize ideas and explore design possibilities.
  • Functional Prototypes Working parts that allow testing of fit, form, and performance before full production.
  • Custom Components Specialized 3D printed parts tailored to unique industry or client requirements.

Our Work in Action

RC Speed Boat

A modular RC boat hull was CAD-modeled and split into 3D-printable sections for easy assembly. Print orientation, infill, and wall thickness were optimized to achieve strength while keeping the structure lightweight. PLA+ was used for rigid parts, while TPU provided flexible gaskets and seals for durability and waterproofing. Post-processing steps such as sanding, epoxy coating, and sealing enhanced water resistance and finish. The design featured tool-free maintenance with integrated brackets and screw interfaces, plus a compact internal layout for battery, ESC, and receiver.

ESP32 Robot

A lightweight robot chassis was designed and 3D-printed to integrate ESP32, IMU, and encoder motors. Support-free overhangs, optimized wall thickness, and press-fit tolerances ensured efficient 3D printing. Iterative FDM prototyping refined wheel housings, caster mounts, and electronic enclosures for durability and fit. Built-in cable routing and snap-fit joints reduced post-processing and assembly time. Customized motor brackets and sensor mounts with precise tolerances improved vibration resistance, enabling reliable navigation and performance.

Haptic Hand Keyboard

An ergonomically designed, 3D-printed keyboard tailored for the visually impaired. Built with PETG for durability, it features Braille indicators, finger-fitted grooves, and haptic feedback for clear tactile confirmation. The design ensures comfort, accessibility, and reliable usability over extended periods.

Hexacopter

A custom hexacopter frame was designed and 3D-printed for manual RC flight, successfully tested for 40 hours without GPS. The structure achieved a lightweight build of 890 g through optimized geometry and material selection. Thermal issues in PLA engine mounts were identified, with aluminum replacements recommended for durability. Modular arms and a central hub were created for easy assembly and replacement, while print orientation and layer optimization improved strength-to-weight ratio and ensured reliable fastening through precise hole placements.

Jetson Nano Robot

A custom robot chassis was 3D-printed using FDM with optimized infill (30–40%) for strength and reduced weight. PLA+ was used for prototyping, while PETG/ABS were recommended for final builds to improve heat resistance and impact durability. Components such as camera and sensor housings were designed for support-free printing, minimizing post-processing. The robot integrates encoder-driven DC motors with a differential drive system for precise navigation, and features LiDAR/Camera mounts for real-time mapping, object detection, and computer vision applications.

Behind every line and model lies our passion to create, refine, and deliver excellence.
