Engineers Find New Method For Developing Stronger, Lighter 3D-Printed Parts

Engineers at the University of Maine are developing a new method to more accurately predict the strength of lightweight 3D-printed objects. This research, conducted at the university’s advanced structures and composites center (ASC), will enable designers to create more robust and reliable components by contract virtually any plastic component.

The research team was made up of Philip Bean, Research Engineer at the ASC, and Senthil Vel, Professor of Mechanical Engineering, AlongSide Roberto Lopez-ANIDO, Professor of Civil Engineering.

Their study, published in Progressive additive manufacturingIntegrates Advanced Computer Modeling with Physical Experiences to Provide a more comprehensive undersrstanding of how these parts will perform the under stress.

They focused on gyroid infill, an intricate, reepeting internal structure commonly employed in 3D printing to minimize weight white preserving structural integrity. By utilizing computer simulations to analyze the gyroid’s response to various forces, the team validated these predictions through experiences through experiences on 3D-printed protypes.

The Findings Offer Insights Into How this Complex Internal Pattern Contributes to a Part’s Overall Performance; A Factor often Not Possible With Conventional Analytical Methods.

“This Work Allows Us to Design 3D-Printed Parts With Greater Confidence and Efficiency,” Said Bean, One of the Lead Researchers. “By undersrstanding the precise strength of these gyroid-informed structures, we can reduce material use and improve performance across industrys.”

This method is anticipated to significantly Benefit Sector Demanding Strong, Lightweight Materials, Including Aerospace, Automotive and Medical Device Manufactory.
