Binder Jet 3D Printing
Conventional subtractive metalworking processes generate a lot of waste and are time-consuming.
These process routes are also very restrictive on product design freedom. On the other hand, Binder-Jet 3D printing process is a form of the additive manufacturing process that involves the deposition of metal powders layer by layer, followed by the application of a liquid binding agent. This process is repeated until the desired object is fully formed.
Key features:
- Minimum feature size: 0.7 mm
- Tolerance Achievable: ±2% of Nominal
- % Theoretical Density: 99%
- Surface finish along X & Y Axis: 3-5 µm (Ra)
- Surface finish along Z Axis: 5-7 µm (Ra)
Laser powder bed fusion is a metal 3D printing process wherein a high-powered laser selectively melts and fuses metal powders together layer by layer. The laser is precisely controlled by a computer-based system, ensuring accuracy and intricate detailing. This technique allows for the fabrication of complex parts, consolidating multiple components into a single piece, thus reducing assembly time and improving overall performance. It is utilized for producing components like turbine blades, medical implants, customized automotive parts, and high-performance tools.
Key features:
- Minimum feature size: 0.5 mm
- Tolerance Achievable: ±2% of Nominal
- Surface finish along X & Y Axis: 5-7 µm (Ra)
- Surface finish along Z Axis: 8-10 µm (Ra)

Lithography-based Metal Manufacturing
Lithography‐based Metal Manufacturing (LMM) technique is one of the modern day 3D printing technology, LMM uses photopolymerization to build parts in a layer by layer process via exposure by using light. In comparison to conventional stereolithography processes, the raw material (feedstock) consists of metal particles which are dispersed in an organic binder phase. INDO-MIM feedstocks exhibit unique properties instrumental for the LMM process.
Key features:
- Tolerance capability: ± 2 % of Nominal
- Minimum Feature Size: 0.1 mm
- % Theoretical Density: 98%
- Surface finish along X & Y Axis: 2 µm (Ra)
- Surface finish along Z Axis: 2.5 µm (Ra
Benefits of Metal 3D Printing:
- Accuracy: One of the most observed aspects of metal 3D printing is its high accuracy. It enables manufacturers to produce parts with very complex designs with high accuracy.
- Lead Time: 3D printing process requires less lead time to manufacture parts irrespective of complex design and without machining.
- Design Flexibility: Comparing the conventional method in which tooling and a mold are required, in metal 3D printing there is no requirement for tools and a mold, so the designer will have much opportunity to find innovative and customized solutions that were not possible in the conventional method.
- Rapid Prototyping: Metal 3D printing will decrease the time to do a prototype compared to the conventional method. This will help the engineers to produce functional parts and test or refine them, which will reduce the time from concept to final product.
- Material Efficiency: Compared to the subtractive method, here the material is used only where required. This makes the metal 3D printing material efficient.
