Engineering Challenge Video: Will It Tumble?

Watch our latest engineering challenge to see whether certain design features printed in different processes and materials will survive repeated crashing and falling in a cement mixer.

Will it tumble gif

In our latest challenge, Greg Paulsen, Director of Application Engineering, tests fourteen 3D printed materials made using six industrial additive processes. The parts endure continuous small drops in a cement mixer to gauge their durability. These samples were designed with thin walls, overhangs, ribs, lattices, and more to see which features would meet their match. Which ones do you think will survive?

Watch now to find out.

What Else You Need to Know About the Test

  • Each 3D printed part is a half-sphere measuring 4” diameter
  • Full spheres were assembled from two halves, which allowed even exposure of features during the test
  • All the parts contained the same feature sets
  • Fourteen materials and six processes were used—see the table below.
  • Once a half-sphere was highly damaged, it was removed from the test and the remaining sphere was combined with another low-to-medium damage part

They call me the Director of Application Engineering at Xometry. This means I not only get to produce great design-for-manufacturing content but also consult on various custom manufacturing projects using CNC machining, additive manufacturing, sheet metal, urethane casting, and injection molding. If you have a question, I'm your guy.
