Why Bamboo and 3D Printed Metal are the Same!

When things have a purpose you’ll find they’re designed for that purpose! There’s evidence of design.
Even though, on first glance, bamboo and 3D printed metal seem to be opposites they have a lot in common when we think about them from a design point of view!
Recently I found myself explaining specific projects I’ve designed that used bamboo and a separate one that used 3D printed metal and realized I was explaining them in similar ways…so this video brings that thinking together…enjoy!
About Me:
Hi, I'm Paul Kassabian. I'm a structural engineer and a Principal at SGH in Boston, MA. Being a structural engineer is my fulltime job and I’ve also taught full courses to graduate students at MIT for nine years, Harvard's Graduate School of Design (GSD) for five years and at RISD (Fall 2023). These are videos based on my structural design projects and years of teaching structures to students.
Some legal/professional things:
As of this video, I’m a:
• Licensed Structural/Civil Engineer in 26 US States including my home State of Massachusetts.
• Professional Engineer in British Columbia
• Chartered Structural Engineer in the UK (both ICE and IStructE)
So my full work designations are: Paul E. Kassabian, P.E., P.Eng (BC), C.Eng MICE MIStructE

I work for a big 3D printing company and I wish my clients would understand this concept ! Too many designer think about 3D printing when their concept is finished and they are struggling to produce it, while it should have been taken in account from the begining.

A fancy new KZbin set! I'm excited because I really enjoy your videos and I hope this change of scenery is an indicator that you plan to make more great content soon 🤞 Small, but hopefully constructive critique: From a writing/editing perspective, I think you did a good job explaining bamboo given the prerequisites I learned from some of your other videos (e.g. strength of a column comes from the perimeter), but I'm afraid you gave short shrift to the titanium structure. For example, you said the titanium was hollow but only in passing and didn't quite "show" that as you did with a cross section of the bamboo fibers. That made the "I think we can all agree" feel rushed. Perhaps you could have stuck a skewer or straw into the titanium structure to "show" it was hollow.

I’ve got a lot of bamboo growing in my yard I’ve been dehydrating I should print some brackets to hold them into sheets for vertical supports I hadnt thought about how great its longitudinal strength is

Muchas gracias por tus videos ! Son exelentes

Idunno about that buttercup argument. I feel like one could similarly argue that a waterfall is a mechanism "designed" to get rainwater back towards the Earth's centre-of-mass in the quickest way possible.

[@yaregalmengistie]

Design! I have never seen that way. Thank you!

[@PaulKassabian]

You’re welcome 😊

[@tatianatub]

they are also the same in that they function as metaphorical hammers that some designers with little to no practial experience use to bang on the preverbial nails when a simpler solution woud have suffised.

tip your video editor!

Brilliant! Evolution is such a great designer. Probably because bamboo is such fast growing it can't waste placing any material where it's not needed. It needs to get that structure quickly as it is adding more load and height quickly. What about the cross pieces every so often? Do they add significantly to the strength of the cylinder? Excellent new lighting in your studio.

[@PaulKassabian]

Thanks and, yes, the regular spaced "nodes" provide buckling restraint to the bamboo length (also called the "culm").

[@lawrenceberlinski7643]

I literally look at things differently because of your videos. Thank you.

[@PaulKassabian]

Happy to hear that!

[@seraaron]

"design" is doing a lot of heavy lifting in that buttercup example
