GE USES Its Metal 3D Printing System To Prototype Jet Engines Within 12 Weeks
Feb 02, 2018

GE engineer team, said they were able to 3D printing and testing 30 football the archetype of the size of the jet engine components, and in just 12 weeks using change spray gun technology to achieve the final version of the rules of the game.The company says it will take years to use the traditional foundry process.

Ge first about its incredibly rapid metal 3D printing system of thinking is in December 2017, the company launched its new H1 3D printers, a prototype of the first photo.The prototype system took just 47 days to build, inspired by the successful use of jet engine parts in the jet engine.


Adhesive jet printing technology USES adhesive materials to basically bond metal powder particles into specific shapes and structures.This process is obviously different from laser sintering process. Laser sintering process USES laser beam to melt metal powder and fusion layer until a shape is formed.Adhesive spray technology in and of itself will be specific (and proprietary) adhesive material deposition to the flat bed of metal powder, which makes metal particle anywhere in the applying glue stick together.This is a layer of repetition until the desired structure (determined by a three-dimensional model) is completed.

Obviously, the deposition of the binder takes less time than the laser sintered metal powder, just as GE claims that its binder is capable of printing "at least 10 times faster" than the laser system.And it can also produce larger parts.

Another key advantage of the new machine - it is reported that it will take 47 days to make - is less than a 3D printer using a laser printer."We're not putting high-power lasers on a metal powder bed, we're putting adhesive on paper," explains Arunkumar Natarajan, a senior scientist at GE Global Research and head of the technology for the injection project.

"We emerged from the deep material and chemistry expertise of GE research LABS to develop a special adhesive that is at the heart of the process's success.We are very excited about the concept of activated 


The GE Additive team has a 3D printed LEAP engine process component.

Ge's recent achievements in adhesive injection technology involve a variety of (more than 30) prototypes of 3D printed CFM international company LEAP jet engine components.The new 3D printing technology has been designed, iterated and tested many times in just three months, given that it takes years of engineers to design and verify the original engine parts.

Ray Martell, GE aviation's chief engineer, said: "due to strict alloy requirements and complex geometry, this flow component is a manufacturing problem."The combined agent jet can meet these challenges with the significant cost advantage of traditional technology."

The 3D printing jet engine project is led by Martell and Ken Salas, the head of the additive manufacturing platform of GE global research.The results, they say, are promising because they think it is easy to expand mass production.Ge has even claimed that jet technology could save LEAP tens of millions of dollars.
