Scientists to test using 3D metal alloys in tissue repair

AM aerospace revenues could reach more than a billion dollars

Researchers from the University of Pittsburgh’s Swanson School of Engineering and McGowan Institute for Regenerative Medicine (MIRM) have begun a project looking at the addi-tive manufacture (AM) of biomedical devices from bio-degradable metallic alloys.

The US$590,000 project was one of 15 selected by America Makes as part of its second call for additive manufacturing (AM) applied research and development projects. It will take 18 months to complete.

“Additive manufacturing combines the best of tech-nologies – the ability to con-struct complex structures via computer imaging utilising a combination of advanced biocompatible and more importantly, biodegradable alloys,” said Dr Prashant

Kumta, principal investigator of the project. “Thanks to computer-aided tomography, or CAT scans, we can directly image a damaged structure like a bone or trachea and construct a biodegradable iron-manganese based scaf-fold to promote natural tis-sue growth during the heal-ing process. This reduces the risk of disease transmission via methods such as bone grafting, and allows for a more precise framework for the body to heal itself by controlling the degradability of the alloy by careful alloy design and engineering.”

AM also makes it possible to use biodegradable alloys that serve as functional scaf-folds for inducing cells to grow, as well as platforms for delivering biological mol-ecules and antibiotics, rather than as artificial implants.

Benefits of metal

“Although we could create a ceramic or plastic part with additive manufactur-ing, this is not as ideal as an iron-manganese alloy which is stronger, more ductile and degrades over time to be replaced by new bone,” added Dr Howard Kuhn, co-principal investigator.

The scaffolds are sintered to provide structural integ-

rity to the bonded particles. During this phase of the research, the scaffolds will be evaluated for biocompat-ibility, bioresorption and mechanical properties.

The researchers plan to produce some of the biomedical devices such as bone fixation plates and screws, as well as tracheal stents in preparation for later clinical studies.

Using AM, it may be possible to build a biodegradable iron-manga-

nese based scaffold for a damaged bone to promote natural tissue

growth during the healing process.

According to a new report, the additive manufacturing (AM) market for aerospace could attain US$805 million in rev-enues by 2019, and go on to reach US$1.2 billion by 2023.

Aerospace is the second largest industry sector served by additive manu-

facturing (AM), after dental/medical AM, and using AM for prototyping has been part of aircraft manufacturing since the 1980s. In future AM could enable aerospace firms to reduce labour costs, mini-mise manual assembly, and reduce the weight of aircraft.

Metal powder bed systems account for most AM applied in aerospace. By 2019, revenues from powder bed equipment alone are expect-ed to be more than US$305 million, growing to US$485 million in 2023.

The report suggests that the use of powder bed equip-ment can further the use of titanium and nickel materials in commercial aircraft, noting that recently developed pow-der bed systems are becom-ing more robust industrial machines that can handle more types of materials and different types of energy source.

The report, published by SmarTech, also emphasises that AM can lead to substan-

tial weight reductions; a priority in the manufacturing of commercial aviation since the gas price hikes of 2004. Case studies have shown that using AM can result in 50-70% weight reduction in select parts, creating a strong incentive for AM to be used in aerospace manufac-turing.

Material demands

It is also estimated that AM manufacturing of some parts in an airplane could reduce aircraft manufacturers mate-rial consumption by 75%. Because of the cost effective-ness of AM, the report sug-gests that AM materials sales to grow to about US$150 million by 2019.

The AM market for aerospace could reach US$805 million in

revenues by 2019, and go on to reach US$1.2 billion by 2023.
