LaserOrigami is a rapid prototyping system that produces 3D objects using a laser cutter. LaserOrigami is substantially faster than traditional 3D fabrication techniques such as 3D printing and unlike traditional laser cutting the resulting 3D objects require no manual assembly.

LaserOrigami: Using an unfocused laser to heat the acrylic causing it to melt and bend, rather than cut. This is a great idea!
I KNOOO ITS SO SMART
That is just amazing! First time i have ever seen plastic being manipulated like that
Very clever idea. Adds a new functionality to the cutter that I never even considered.
This is a VERY clever 2D fabrication technique!
Very innovative use of a laser cutter, I'm impressed :D
Great question :). We are currently working on an Illustrator plugin that provides the necessary tools for creating bends, suspenders etc. However, this needs more work and we will upload it when we are done.
LaserOrigami is part of my dissertation under the supervision of Prof. Patrick Baudisch at the Human Computer Interaction Lab at Hasso Plattner Institute. We have more awesome projects on our website (link is in the video description). Thanks :).
Love this. Can't wait to try it out. Can think of a good few uses for this.
Absolutely fantastic. So much fun to be had.
i never tought about this you are a genius person
i looked at this and my mind was completly blown
This is amazing. Good job.
Fantastic idea! I think I can run a more rudimentary version on my Epilog as it is now. I might just have to run a few separate jobs with some focus jigs. Truly inspiring!
To those who call this a waste of material, you can use smaller sheets of acrylic to make your items, and you can use the leftovers for other, possibly flatter, things. Would you call it a waste of butter if you had a recipe that calls for 1/4 of a stick? No, you'd keep the rest of the butter and use it for something else.
thanks! great idea with the fixtures. For angles other than 90 degrees we currently either use a motor or a third hand (you probably know this from soldering things) that holds the workpiece at a certain angle.
Awesome idea! Looks like a lot of frustration while figuring out the correct parameters for bending without cutting. Very nice results!
Really good idea. Thank you. It is wonderful
In this video we use 1.5mm acrylic. But the process should also work with acrylic of different thicknesses and other thermoforming materials.
This is a great idea, congratulations ! I'll try that !
Universal Laser cutter machines are great i have use to one myself and its awesome make sure you clean your mirrors and reflecting mirrors or it looses power also got a gravograph 900lx
Nice demo
Nice way to use the unfocused laser as a precise heat source.
Very Clever, love the use of the Servo and 3d printed Servo holder.
Laser cut servo holder......
@Stefanie Mueller Oh okay. Thanks for the reply! Will have to try it once we get our laser.
These are alternatives. You can either use the CAD interface and draw on your computer screen _or_ use the interactive fabrication interface and draw directly on the workpiece. Sorry, we should have made this more clear in the video. Hope my answer helps to clarify this.
Wow.. never seen anything like this before!
Good idea. Thanks for the tip!
Wow this is amazing !
That's what I was thinking, very nice machine you have there!
i work with trotec speedy 300.. but you have superb ideas. Respect :D
Very witty!
I have to try this new technique, haha!
Thanks for sharing.
Amazing lateral thinking!
Amazing... you are a genius!
Stunning idea
That is one of the coolest things I've ever seen.
very amazing laser-cutting machine!
Thanks! Yes, this is a CHI 2013 fullpaper and will be released in May. I will be happy to send you a prerelease version. Just email me (my webpage link is in the video description).
que hermoso tu trabajo
Awesome!
I use 1.5mm translucent acrylic. LaserOrigami is as efficient in terms of material as normal lasercutting. Only for the video I placed the objects in the middle of the plate and used a new plate for every video segment. Of course you can position it differently ;).
actually a very cool idea! How useful or economical? that is a different matter
Amazing!!!!
Great work nicely shot. Thanks for posting that. I realy cannot understand the negative comments. If people want to moan about a waste of materials etc they should go count the yachts in the bay.
Clever I liked home you weakened and heated the edges to create the folds NICE !
Really interesting. I previously used the unfocus effect + multiple pass to achieve rounded edges similar to mould and to "groove" various depth and width but never thought of using this to bend. Even if limited this has good applications for small series of small items like the holders you demonstrated.
I downloaded you paper and your slides. But the slides archive seems to be corrupted.
Are you thinking of going a step further and bringing this to the market?
Are your libraries of examples available ?
Thanks in advance
My same thought. A benefit of 3d printing is that one does not lose materials often.
great video
It's all about heating the acrylic to a point where it gets compliant. If your laser cutter can reach this temperature mainly depends on the power of the laser. I mainly worked with 1.5mm, but also tried 3mm once.
Good work 👍🏼
Nice stuff
so good the machine and the acrylic products creator.
could you please share your settings, i'm interresten in the z defocus you are using
very good performance
excelent!
All materials that get compliant when heated up can be used (in other words: all thermoforming materials) and they need to have a transition temperature low enough so that it can be reached by the power of a regular laser cutter. For acrylic the transition temperature is around 110-130 degree. For glass it's much higher so I don't think it can be reached by a normal laser cutter.
Our focus is on expanding what DIY laser cutters can do today. With DIY I mean the typical machine a FABlab would own. But thanks for the hint, it's definitely interesting to also think into this direction, but in a different context.
True that. My personal belief is that having to "look something up" in 2013 isn't exactly the chore it was a couple decades ago, so there should be no excuse for ignorance anymore.
is it simply heating the plastic and that is what is allowing it to bend with the gravity or it is slicing it thinner until it bends? I'm curious at to how this is achieved because of both have entirely different strength properties at the creases. Really innovative process.
Cool!
It is amazing, greet job.
Awesome stuff. I'm happy that I'm going to study Photonik Technik in Deutschland.
Not sure I get your point. For the video I put the lasercut object in the middle of the acrylic plate so its easier to see and I used a new plate for each video segment. But in general all material that is used goes directly into the final object, so its as efficient in terms of material as normal lasercutting.
Hallo.
Tolle Sachen macht ihr da!
Ist das ein spezielles Acryl Material, dass da verarbeitet wird ?
I haven't seen laser cutters which will change the z depth while cutting which you show in 1 : 40. Amazing work
I should give it a try in school laser cutters
genius !!
Thank you
do you have another video showing raw video speed, curious about cut times in real time, thanks awesome stuff
This is cool. I like that video
Awesome work! Never knew this could be accomplished with a laser cutter!
can any laser cutter with a Z Axis do this?
thank you.
Sorry if it is posted somewhere else, but I did not see what type of laser you are using....could you please let me know and maybe the cost, power, and such?....Thank you.
Found it in the comments....PLS6.150D with a 1.5 lens
Now this... This is creativity. (Inb4 this is Sparta!)
So if you need to have multiple edges bend at the same time, how does the laser handle all of them at once so it doesn't warp? Are you planning on adding lasers for more complex designs? This is pretty awesome
very very good
At 2:30 there was a small machine that rotated the part. I was wondering what the ball barrings in its botton were for. My first thought was weighing it down but then I thought that the machine must but fixed in place if the laser is going to give precise cuts.
Very cool video and Machine. Thumbs way up
I'm currently working on a small tutorial to explain the different steps. In short: Use a lens with a short focal length to make sure it defocuses quickly. I use: 1.5 Lens from ULS, power: 40%, speed: 30%, z: 50mm. But this heavily depends on your laser. For details go to my webpage, click on the LaserOrigami link and scroll all the way down (still work in progress).
I put a 3x in the top left corner when I sped up the video in the full-length examples. The rest is real time. So just multiply the different parts by a factor of three.
Impressive, I never considered using the laser in this way. Have you considered adding a fixture under the acrylic to allow you to generate angles other than 90 degrees?
Awesome!! I have a helix epilog, can I that with it? How do you control the focus on the laser? I'll love to do it. We work with schools and kids from vulnerable populations, they will love it
This is a laser cutter from universal laser systems (PLS6.150D). Prices vary, so I think the best thing is you send them a price request on their webpage. There are also smaller and larger laser cutters available. Also other companies sell them, such as Epilog and Trotec. Our laser cutter techniques should work with any laser cutter model that has a movable motion table (z-axis).
Sehr beeindruckend! Das lässt nicht nur Leuten mit Lasern als Hobby das Herz höher schlagen (weniger Montage!), sondern auch öffnet auch interessante Aspekte im Bereich der Technik.
Heutzutage sind ja selbst hochintegrierte Schaltungen auf Folien und dergleichen möglich, da wäre das "selberbiegen" und "strecken" ein interessanter Schritt für MID. Da könnte man ja quasi Formgebung nach Bestückung machen!
Ein Hoch aufs Rapid Prototyping, DIY und ich wünschte, das gäbe es auch an unserer Uni! (FAU Erlangen-Nürnberg)
Wobei ich mich frage, ob man spezielles Programm oder Equipment braucht, oder das mit Epiloglaser und Visicut auch erreichbar wäre?
Hi,
your job is great and very interesting, I would like to have a small question : why do you have the step 2 : interactive fabrication. I think step 1 is enough since you have the drawing-> you have the coordinate
clever idea to bend the acrylic
What do you do with the excess material left over? Seems to get pricy after a while.
Also are the cuts clean and true enough to bond pieces together?
This is a laser cutter from Universal Laser Systems (PLS6.150D with a 1.5 lens). But every lasercutter that has a platform that can be moved up and down should work.
Impressive
hi it is really nice to see 3d work pls let us know which material u are using for 3d is it acrylic or some other pvc material .
stefanie i have a question for u, is awsome this process but i need to know what is the song tha u used! thanku so much
Hi, I wanted to know if a normal laser cutting and engraving which will adptaron a movable table in the Z axis or a special machine
thanks
live this
Great! What kind of laser do you work with?
There is no wasted material. I only used the big sheets for the demo, so that you can see it better in the video. You only need as much material as the object shape requires (think: using a heatgun). You can position the object freely on the plate.
Begeisterung pur
How is the feedback done that the material is actually bend so that you don't eventually cut through it?
Raymond Doetjes it used a out of focus beam to heat the crease but not cutting through it, then let gravity do the bending job
For the bending portions, does the laser just heat the plastic so it bends, or does it etch away until it is weakened enough to bend?
nice!!!
We think of the LaserOrigami mechanism as a replacement for finger joints. Instead of connecting two edges with finger joints one could also use an automated LaserOrigami bend. Making a perfect tube is not possible to my knowledge, but I guess one could make a rough approximation of it.
This would be excellent for making a custom case for a control panel.
Questions. Can the processes be used with thicker 3mm acrylic? Also any chance of getting those visio files or better yet the DXF?
Artist: Wasaru. Title: Can we speak. It's free for download. Just search for him.
I work in the model shop at my school. I recently discovered this and would love to try it out.
I realized we have a z direction control so id be able to do something like this. Is there somewhere that would show me the setting to do this or was it just trial and error?
Sehr cool! Ich hätte noch eine Frage: Wie groß darf das Verhältnis Kantenlänge/Fläche maximal sein, damit die Schwerkraft ausreicht um es richtig hinzubiegen?
I just wanted to make sure the motor would not fall over. Nothing fancy :).
NOW we're talking advanced laser cutting! Will there be a paper released on this in the near future?
