Summseed integrates Meltio's metal 3D printing into the steel industry

Published on May 01, 2026 | Translated from Spanish

Summseed has decided to incorporate Meltio's metal additive manufacturing technology to modernize its steelmaking processes. The company aims to optimize the production of metal components through laser wire deposition, a technique that reduces material waste and enables complex geometries. This commitment could mark a turning point in traditional steel manufacturing.

Description (80-120 characters):
Summseed applies Meltio metal 3D printing: robot with laser head deposits wire on steel part in industrial workshop.

Laser wire deposition: precision without a mold 🛠️

Meltio's system uses a laser head that melts metal wire layer by layer, without the need for molds or subsequent machining. This allows for the creation of large parts with specific alloys, minimizing scrap. Summseed plans to integrate this technology into its production chain to manufacture structural components and heavy machinery. The key lies in efficiency: fewer steps, less waste, and more control over the properties of the final material.

From ingot to filament: steelmaking goes modern 🤖

A steelmaking company switching to 3D printing is like seeing your grandpa using TikTok: surprising but promising. Summseed has decided to swap the pneumatic hammer for the laser pointer, and instead of melting tons of steel only to discard half, it will now print only what is necessary. Hopefully, the engineers won't forget to pause the program when they go to the bathroom, because a 500-kilo part can't be stopped with just any emergency button.
