Engineers from RMIT University have used inexpensive, readily available materials to develop a new type of 3D-printed titanium approximately 1/3 cheaper than commonly used titanium alloys. In a study published in Nature Communications, the research team outlines a time- and cost-saving method to select elements for alloying to take advantage of emerging 3D-printing technology.

The researchers found their alloy prints more evenly than many other commonly 3D-printed alloys, which are prone to column-shaped microstructures leading to uneven mechanical properties. Testing also demonstrated improved strength and performance compared to standard 3D-printed titanium alloys – in addition to being 29% cheaper.

RMIT has filed a provisional patent and is seeking partners from across medical and aerospace supply chains to collaborate with its Centre for Additive Manufacturing (RCAM) on the next steps of development and commercialization.

3D-printed monolithic solution

3D Systems announced full commercial release of its NextDent Jetted Denture Solution for the U.S. market. The company’s solution for jetted, monolithic (one-piece) dentures uses multiple materials in a single 3D printing process, resulting in a faster, more cost-effective, and highly scalable alternative to traditional denture fabrication.

The solution is based on 3D Systems’ NextDent 300 MultiJet 3D printer enabling rapid production of patient-specific dentures that are fully cured and safe to handle without the need for additional post-curing steps. It’s accompanied by the FDA-cleared dental-specific materials NextDent Jet Teeth and NextDent Jet Base, which deliver tooth rigidity and gum support along with durability and aesthetic quality.

Beta testing of the NextDent Jetted Denture Solution demonstrated a 50% reduction in manual labor and capability of producing a final product in a single day compared to the five-day turnaround required by traditional one-piece denture production methods.
