Area of Science:

  • Additive Manufacturing
  • Mechanical Engineering
  • Materials Science

Background:

  • Heavy powder-laying arms in metal 3D printers risk damaging critical components like servomotors and belts.
  • The need for lighter, more durable components is crucial for enhancing the longevity and performance of metal additive manufacturing systems.

Purpose of the Study:

  • To design and validate a lightweight powder-laying arm for metal 3D printers.
  • To reduce the mass of the powder-laying arm without compromising its structural integrity or functionality.
  • To investigate the effectiveness of topology optimization in achieving mass reduction for 3D printing components.

Main Methods:

  • Reconstruction of the original powder-laying arm using Rhino 3D modeling software.
  • Topology optimization design applied to the reconstructed arm using Altair Inspire software with a 25% mass objective.
  • Manufacturing and assembly verification of the optimized arm using an Aurora Elva 3D printer.

Main Results:

  • Original arm exhibited maximum displacement of 4.319 × 10-5 mm and maximum stress of 3.843 × 10-2 MPa.
  • Topology optimization resulted in a significant mass reduction while preserving connection integrity.
  • The 3D-printed optimized arm demonstrated excellent surface finish, low roughness, and accurate assembly without defects.

Conclusions:

  • Topology optimization is an effective method for significantly reducing the mass of metal 3D printer components.
  • The lightweight, 3D-printed powder-laying arm ensures structural integrity and seamless assembly, suitable for mass production.
  • This optimized design enhances the reliability and performance of high-performance metal 3D printers.
