I think we are coming to incredible levels in additive manufacturing technologies. One of the latest examples of this is Meltio and the technologies it has developed.

I've already included their comprehensive article at the end of the post, but to summarize, it looks really cool to be able to make parts using two different alloys together in additive manufacturing. Manufacturing is based on melting and precise deposition of additional alloy wires with laser technology.

🎬 You can get an idea by looking at this short 40-second video.

In the related article, it is discussed how a screw compressor is produced with the use of 3D printing technology..

A female steel screw compressor, used in industries like mining and petrochemicals, features two interlocking screws (one female, one male) that rotate to compress air or gas. Traditionally, these compressors are made through cutting, forming, welding, and CNC machining, which are labor-intensive, costly, and generate material waste. However, using Meltio technology for manufacturing improves efficiency by enabling the production of complex, customizable designs with less waste, faster production, and high-quality results. This method also supports limited-edition models without compromising the compressor’s mechanical properties.

Using dual-wire Meltio technology offers several key advantages:

  1. Material Versatility: High-cost alloys like cobalt and nickel can be integrated to enhance mechanical properties, such as improved corrosion and wear resistance. Meltio’s system allows easy switching between materials, customization of parameters, and the use of various materials to suit different applications.
  2. Enhanced Functionality: Dual-material parts can combine strengths, such as adding hard-facing or anti-corrosion coatings, while avoiding cross-contamination. This selective use of materials optimizes the functionality of specific sections, like high-strength components or areas needing better thermal conductivity.
  3. Efficient Support Structures: Temporary supports and rafts can be printed with lower-cost materials, reducing waste and preventing deformation during the process, further improving production efficiency and quality.

🫡 I will continue to follow this technology with curiosity and keep you informed.
