MANDI: Researchers at the Indian Institute of Technology Mandi, in collaboration with international partners, have found that a specific metal 3D printing method, called mFFF/FDMet, is the most cost-effective and superior among various approaches.

This technique, known as extrusion-based metal additive manufacturing, uses fine metal powders to create intricate components layer by layer.

Led by Dr. Prateek Saxena, the team outlined the advantages of mFFF/FDMet in a publication in the journal Composites Part B.

The process stands out for being less hazardous and offering more design freedom compared to popular methods like Powder Bed Fusion (PBF) and Direct Energy Deposition (DED).

The five-step mFFF/FDMet method involves filament fabrication, 3D printing, debinding, sintering, and post-processing.

Despite being a longer process, it proves to be more economical for mass-producing metal parts compared to traditional methods.

The researchers stress the importance of adopting this technology to empower potential producers and break the monopoly held by foreign companies in the metal 3D printing industry.

The global metal 3D printing industry is gaining momentum, and the Indian government is committed to developing indigenous products for various sectors.

This research provides valuable insights for those looking to conduct cost-effective and efficient metal 3D printing based on global studies.
