Why 3D Printed Bridges are Better | Additive Manufacturing Podcast

Today, the Additive Manufacturing Podcast team discusses Vertico’s 3D printed concrete bridge, non-plainer 3d printing, and Stratasys 3d printed fashion.

2:40 Vertico, a 3D printing company recently printed a bridge. The cool thing is that their 3D printed bridge used 60% less material than its traditionally manufactured counterpart. Despite using much fewer materials, Vertico says that 3D printing helped to create optimized structures that are able to withstand the same stresses as a traditionally manufactured bridge.

“This bridge showcases the range of possibilities that 3D concrete printing offers,” explained Volker Ruitinga, founder of Vertico. https://3dprintingindustry.com/news/vertico-constructs-optimized-footbridge-using-3d-concrete-printing-161729/

A new approach to fused filament fabrication (FFF) slicing has been proposed by researchers from the University of Hamburg’s Department of Informatics. The work began in 2018 with a Master thesis.

The researcher’s method combines both nonplanar and planar layers to remove the “stair-stepping effect” on 3D printed surfaces. The resulting prints are stronger, of higher quality and provide smoother 3D printed object surfaces.

11:14 To do this, the researchers developed a slicing algorithm that detects which parts should be printed as nonplanar layers. They explain: “With this approach, the printable areas are detected automatically and checked for possible collisions while printing… The modified Slicer then generates a nonplanar toolpath on top of the regular layers.” https://all3dp.com/4/nonplanar-3d-printing-gives-the-smoothest-top-layers/

20:10 As New York Fashion Week (NYFW) 2019 draws to a close, the prestigious clothing event flaunted a number of flamboyant designs and inventive collections. 3D printing has played an increasingly relevant role within recent major fashion events due to the creative freedom it offers designers, and this year’s NYFW was no different. https://3dprintingindustry.com/news/stratasys-3d-prints-directly-onto-clothing-for-threeasfour-collection-at-new-york-fashion-week-161705/
