Sigma Labs, Inc. (SGLB) announced that it has filed a patent application protecting a unique sensor invention that will significantly enhance the ability to improve the quality of additive manufacturing processes especially for critical metal parts used in aerospace, automotive and defense.

Additive manufacturing, for example Selective Laser Sintering uses lasers as its power source to sinter powdered material, binding it together to create a solid structure. But currently, the additive manufacturing process involves a lot of trial and error in order to get the right operating parameters, said Mark Cola, CEO and President of Sigma Labs.

New materials, new shapes, and new parts offer production challenges and companies have to use their best judgment and past experience to get the best printing result.

"To know precisely when the laser is putting in just the right amount of energy into the powder layer - not too much and not too little - so that the layer is completely melted without overheating it is very important." Mr. Cola further explained.

"Our new sensor and data analysis invention helps to accomplish just that - determine optimal coupling between the laser and the powders. As we proceed with development, we expect to offer this sensor to current and future customers of our PrintRite3D systems."


Thanks to Jose for the tip!
