How To 3-D Print a Steel Bridge

Jun 16, 2015 Agence France-Presse 
(Article from IndustryWeek, June 17, 2015)

'The underlying principle is very simple. We have connected an advanced welding machine to an industrial robot arm.'
A 3-D printer at work.

THE HAGUE, Netherlands – A Dutch startup has unveiled plans to build the world’s first 3-D-printed bridge across an Amsterdam canal, a technique that could become standard on future construction sites.

Using robotic printers “that can ‘draw’ steel structures in 3-D, we will print a (pedestrian) bridge over water in the center of Amsterdam,” engineering startup company MX3D said in a statement, hoping to kick off the project by September.

The plan involves robotic arm printers ‘walking’ across the canal as it slides along the bridge’s edges, essentially printing its own support structure out of thin air as it moves along. 

Specially-designed robotic arms heat the metal to a searing 2,700 degrees Fahrenheit (about 1,500 degrees Celsius) to painstakingly weld the structure drop-by-drop, using a computer program to plot the sophisticated design.

“The underlying principle is very simple. We have connected an advanced welding machine to an industrial robot arm,” said the bridge’s designer, Joris Laarman. “We now use our own intelligent software to operate these machines so they can print very complex metal shapes, which can differ each time.”

So far, the robotic arm has been used to print smaller metal structures, but the bridge will be the first ever large-scale deployment of the technology, MX3D spokeswoman Eva James said. It is hoped that the bridge, which also involves the Heijmans construction company and Autodesk software, will be a first step toward seeing the technique used on construction sites, especially those involving dangerous tasks such as on high buildings, she said.

A company in The Netherlands is planning on building a bridge without human labor by utilizing 3D printing technology.

The technique also removes the need for scaffolding as the robot arms use the very structure they print as support.

The designers are now in talks with the Amsterdam city council to find a site for the project which they hope will be completed by mid-2017.

“I strongly believe in the future of digital manufacturing and local production,” Laarman said. “It’s a new form of craftsmanship. This bridge can show how 3-D printing has finally entered the world of large-scale functional objects and sustainable materials.”

Amsterdam city council spokeswoman Charlene Verweij said the Dutch capital was supporting the project, though “We are still in negotiations as to where, exactly, the bridge will be built.”

In two years, a one-of-a-kind construction project will commence over a canal in Amsterdam. It won’t involve any humans at all, but rather, a six-axis robot that can craft molten metal in mid-air. Two months later, a 24 foot-long steel pedestrian bridge will arc its way across the water.

Apologies in advance for probably coming across too pointed, but--
That nice looking virtual structure doesn't look at all capable of handling the weight of TWO industrial robot arms cantilevered as shown (though I'd love to see the video of them spashing into the canal).  Plus, where's the power coming from? (OK, that could be handled by a noisey generator, off camera.)  But why, except for the novelty, would this be better or cheaper than building the structure in a large shop (with robots if you like), and trucking it over?  I'll bet heavily in three years there will be no bridge over that canal.

This post is primarily intended for Brad Flaherty; however, other Makers may find it useful and/or interesting.

igus GmbH recently developed a low-cost 4-axis articulating robot that uses stepper motors for axis drives.  The base configuration starts at about $1,600€ (~ $1,800).  Of course, this price goes up with any customization (end-effectors, system integration, etc.)

This could be a fairly inexpensive, and versatile, robot for an "entry-level" automation project.  

igus GmbH seems to have targeted the "Maker" audience, by offering light-industrial robot features at an approachable price point.  

Incidentally, igus GmbH has a USA-based operation in Providence, RI.

I've scheduled some new classes at the Hack Factory, including an Introduction to Bow Making, and two sessions of Intro to Laser Cutting.

If you've ever wanted to get into archery, or just want to get in touch with your inner Legolas, this is the class for you.

In this 8 hour class, you'll be making a fully functional red oak american flat bow, suitable for target shooting, hunting, or just to have an awesome fully functional costume accessory.  

Bow making class on Saturday, 25 APR: https://bowyer101apr25.eventbrite.com

Laser cutter class on Wednesday, 15 APR: http://laser101apr15.eventbrite.com

Laser cutter class on Tuesday, 21 APR: http://laser101apr21.eventbrite.com

Tell your friends, and please share this anywhere you think it might be of interest.

I've started teaching laser cutter classes again at The Hack Factory, the maker space run by Twin Cities Maker in the Seward neighborhood.​.

Here's one of my laser cutter projects that I was very happy with.

This is custom designed set of tiles and pieces for the game Carcassone.

I ended up making an acrylic laser cut bux to store it in, came out really slick.

If you'd like to learn how to use our laser cutter to make fun stuff, I still have seats in my April 4th class: https://laser1014mar.eventbrite.com
(I know is sayd 4 mar, ignore that, it really is 4 april)

I also scheduled two additional classes, one on Wednesday, April 8th from 10 am to 3 pm: https://laser101apr8.eventbrite.com

and one on Saturday, April 11th from noon to 5 pm:  https://laser101apr11.eventbrite.com

Sign up, tell your friends, and spread the word!

Here's the chair I'm working on. I was hoping to tweak the shape to get it to sit more upright using sketchchair.

The Greenway Glow is taking place Saturday, tomorrow night, and I need your help with my project. I'm going to be launching glowing water balloons through the night sky.

I need help transporting a giant trebuchet from the Hack Factory, at 3119 26th street east, to a spot right near Freewheel Midtown Bike center, roughly 10th ave south on the greenway. Total trip length: about 2 miles, or 8 minutes of driving.

The trebuchet is pretty good sized, but it breaks down into pieces, and just might fit in a good sized pickup truck.

The event starts at 8 pm, so I need to be loading up from the hack factory by 6 pm or so to get there and get everything set up in time.

I'll be taking apart the trebuchet on Sunday, during the day, so there's a lot of flexibility for the return trip.

I could also use some help assembling and operating the trebuchet, and having someone to hand out fliers to people attending the event.

If you can help in any way, please let me know.

You can see the trebuchet in action at Northern Spark 2014: https://www.youtube.com/watch?v=TgWJvGjnp80

Extremely fast laser etching machine. Local company.
Watch toward the end for the payoff.
Now, I'm no artist, but I know when to be impressed. Above is LasX Industries Inc.'s LasX's "Lightguide v5" laser control software at work. It takes a 100,000 vector CAD file based on a work of art by Andy Gikling, and then fully renders it on a blackboard in under three minutes. Wow. I'm so amazed at this laser beam etching at reportedly 6-meters-per-second that I'll stress this: the video above and GIF below are in real-time. Now that's speed...

I still have 2 seats left in my April 25th bow making class. If you ever wanted to get into archery, and learn how to make a bow of your very own, this is your chance.
Here's a pic I found that another archer took, of me using one of these bows at the archery range south of Lake Calhoun (ack, so chubby back then):

Here's a link to the class:
https://bowyer101apr25.eventbrite.com
I'll be scheduling more classes in the very near future, so keep your eyes open.
I also still have room in my Laser Cutter class on April 21st: https://laser101apr21.eventbrite.com

On Saturday, I taught a class on using the super awesome laser cutter at the Hack Factory, and it was a blast. We now have a new crew of people who are up to speed on how to use this super fun tool to make neat stuff.

I wanted to share one of the projects I made with our laser cutter.

This is a set of coasters I made as a christmas present for my mom:  http://i.imgur.com/6brbcL0.jpg

The coasters were designed by my friend Sarah Bray, and I designed the holder. Sarah was kind enough to let me use her design for this present after I told her how much I loved it.

If you're interested in learning how to use a laser cutter to make cool stuff, I have more classes coming up in the future.

I still have room in this Wednesdays class from 10 am to 3 pm:  https://laser101apr8.eventbrite.com

And, there is room in Saturdays class, from noon to 5 pm: https://laser101apr11.eventbrite.com

I'll be teaching more classes on the laser cutter in the future, so stay posted.

I'm also planning some other classes in the near future, namely:

Woodworking 101: a basic course on how to safely use the major woodworking tools at the Hack Factory

Introduction to Bow Making: build a 6 foot long American Flat Bow for archery

Using Inkscape for Laser Cutting: how to use inkscape to create designs to make with the laser cutter

A little further out:

How to survive the Zombie Apocalypse: a one day workshop full of fun, basic survival skills, and Zombies

If you have any questions about any of these classes, please let me know.

Has anyone been using sketchchair? If so, have you had any luck importing SVG files? I just tried WIN and MAC versions and both crash instantly.
