Step 6: Laser Cutting

I fed the vector layout to our laser cutter, and let it rip. It took about twenty minutes to get both layouts cut out. For reference, I used 100% power at 18% speed. You can see images of the pieces being cut out and punched out, below.
<p>Hi guys<br>I've cut recently this stand using a blueprint from internet:<br><br><a href="http://vbp.maxnet.ru/laser1/#wavestand" rel="nofollow">http://vbp.maxnet.ru/laser1/#wavestand </a> (traffic!)<br>+ 2 photos below</p><p><br>It required additional processing since I saw traces of combustion. I've sandpapered the details, covered with woodstain and varnished.</p>
<p>Love seeing this, dk2k. Love all those other projects on that site you got it from, too. I didn't see them posting copies of my blueprints, though. Did you find them on that site, or derive them from the vectors on this instructable?</p>
Hi nagutron,<br>I recall that it was some .eps, can't say the origin for sure. The site vbp.maxnet.ru is mine and all the laser and diy stuff as well. I transformed the EPS into DWG. It lacked symmetry of the parts, I had to alter the width of the notches in order to use 6 mm plywood and increased the height of the supports.<br><br>There is one more benefit: air intake of the laptop isn't closed off
as promised here's mine made from 4mm MDF.
<p>Looks amazing, Mindmapper1! Glad to see it working in a different material. Definitely let us know if acrylic works out.</p>
You can check this free software from autodesk ( http://www.123dapp.com/make ) you can easily construct 3d models with 2d pieces, there are various tutorials and i&acute;m not so sure but i think people can share their models. <br> <br>This other software is specialized in chairs made up of 2d pieces, there is an open library of designs and a dummie for making ergonomic and structure tests. ( http://sketchchair.cc/ ). <br> <br>I hope you find them helpful for your future projects!
This is excellent made it out of 4mm MDF and it is very stable, strong and does not flex at all. Next plan to be made of acrylic sheet. thanks for an excellent instructable.
That is *great*. I'd love to see photos -- post some! MDF is a great idea. I can imagine the slots being much more consistent than with the plywood I used.
great idea..........
Did Pokono's node manual get deleted? I'm curious if / how you can make nodes with a laser?
There's a link to it here: http://blog.ponoko.com/2008/11/03/how-to-create-better-nodes/
Very very nice. This would even look nice as an ornament in the living room!
&nbsp;i joined this website just for this one comment:<br /> <br /> Sorry to say this, but i am in disbelief that this is generating as much feedback as it is. check out the work over at www.grasshopper3d.com<br /> this kind of stand can be made by any architecture student in there sleep if they are familiar with rhino and grasshopper. not faulting you, but you have crossed into a realm of parametric modelling where this would not be taken seriously seeing as how it was created with anything adobe. In a scripting sense this form would be extremely basic to create. I think you should invest a couple hours into learning grasshopper (free plugin) for rhino (not free, just crack). You can change density of the grid, extrusion distances, attractions, and material thickness with simple sliders.<br />
&nbsp;you can see examples where students and practicing architects have built there stuff out of grasshopper. i have written a definition where the ribs generated by the surface automatically notch themselves, flatten out into line drawings, number themselves (for large installations), and line up ready to be exported. extremely practical.
Hey, thanks for the link. Yeah, I would definitely have preferred to have designed this in 3d, but like you say it was a simple shape so I used the tools I knew.<br /> <br /> Grasshopper looks pretty easy to use. I code, though, so I'll probably script in Rhino directly when I decide to pick it up. Thanks for the suggestion.<br /> <br /> Of course, if you model this or something like it, we'd all welcome some screenshots here or a whole instructable of your own!<br type="_moz" />
Nice work! I also spend much time for my design in the SVG app Inkscape. There is a (fresh) free Java application doing exactly your type of work in minutes : http://gregsaul.co.nz/SketchChair/
Just an update, but SketchChair is still not yet available.<br><br>It has been fully funded via Kickstarter since May '11, but the software has yet to be released.<br><br>I'm really looking forward to it when they do, though, because it looks slick!
You have to keep in mind, that the people that come to this site are the average person on the street. Not groups of students from some tech school, And if someone takes the time to learn how to do something like this in their spare time, With practically no help, Then they are to be congratulated, Because true invention, Is creating an idea that you yourself didn't know yesterday, Even if it's only a wheel.<br><br>Aside from that, I do love high tech designs.<br><br>I was wondering if it's possible to create a stand that actually conforms to the shape of a human lap, Or even if one can be made that can be used wether your sitting indian style, Or with your legs straight out. Just a thought, cause thats why my laptop sits on my desk all the time.<br><br>But I love the design, Because of the overall amount of airflow promoted in this project.
I'm a Industrial designer, and i do come here a lot, because I am usually amazed with how people get around to do things by themselves. Sometimes, it's true, you think &quot;man, look how much work this took, and you could have done it in a much easier way by doing this and that&quot; but i still come because many times I find very simple and direct ways to do things, that my degree didn't teach me.
But the fact is they haven't, and he did.
B E A U T I F U L <br> <br>Very nice! I would have to build one!
Could this be done with a sheet of plastic thin enough to use a scissors or box cutter on? You know, like the pendant lamps on this site that use plastic pieces? What I mean is, if you don't have a lazer cutter, could this still be done at home?
I don't think so, unfortunately. The slot joints between the pieces need to be fairly strong, and that comes from the material having some thickness.<br><br>Without a laser cutter, you could try foamcore (which will still be quite weak) or using traditional woodworking tools like a scroll saw to cut wood.
I would recommend using thin plywood (3~5mm) and either a band saw or band saw. Your thoughts nagutron?
Wow, this is really neat, I love how it opens up a whole field of interesting craft possibilities ! I've been working on a slightly different take to the whole 2D to 3D concept with <a href="http://cosmic-spacecrafts.net">The Playful Geometer's Cosmic SpaceCrafts</a> for years now and I just entered the Epilog challenge with my <a href="http://www.instructables.com/id/Quasicrystal-Star-Lantern/">Quasicrystal Star Lantern</a>.&nbsp; I would love to be able to build slatted 3D objects like this with a laser cutter...adding some nice etching designs into the wood would make it look even cooler !&nbsp; I bet it would be possible to create a python script in Blender to output 2D discetions of a 3D object at regular intervals... maybe if I win the contest I'll see if I can throw something together.
Nagutron, aloha from the Big Island~ What a beautiful thing! Originally, in the intro picture, I thought that the shape was so that it would fit on your lap with the narrow end being near your knees, but I see now that it is a desktop set-up...Seems that with a little bit more contouring, it could conform to the shape of the thighs and provide a stable, ventilated base for a laptop...on your lap...<br>Thanks for sharing, and how fortunate you are indeed to work at Instructables~ I am envious....heh heh...but maybe when I move to the Bay area I'll apply....
Interesting idea! I hadn't considered that use and can imagine some tweaks to the design that might allow it to work both as a desktop and laptop stand.<br><br>In any case, I moved on from Instructables a long time ago, but still remember my years there fondly. And I still use this stand every day :)
Very rad indeed!! How do you find it for stability?
I'm an ID student at Buenos Aires (UBA) and this shapes are fairly easy to produce just with rhino -and if you like more control- adding grasshopper. My morphology class teachers are incredibly good at this class and I think the gallery link of our models (we have to actually build the models the end of cuatrimester with our hands) would be usefull for inspirational purposes. http://plm.com.ar/academico/general/indgal.html The more complex shapes are in the advanced &quot;Morfologia Especial 2&quot; course. Have fun!
Sos de Buenos Aires? mira vos, yo soy de La Plata, estoy en ingenieria aeronautica, y necesitaba hacer algo parecido para el ala de un avion, no me explicarias como hacerlo, si se puede con inventor? o con CATIA? si no consigo el Rhino y el grasshoper.
Rhino con T-Splines es lo mejor. Todo lo organico que antes no podias hacer con Rhino lo haces enseguida agregandole T-Splines.<br><br>DI Sara (UBA) ;)
gracias por el dato. se puede cortar asi la pieza? es decir para hacer secciones?
Podes hacer el volumen de como queres que quede el ala, y despues tenes una funcion Contour, que te permite generar las curvas como si la cortaras con planos paralelos en el eje que vos le definas con la separacion que vos quieras. A eso despues le dibujas las que apoyan perpendicularmente para armar el armazon.<br>El T-Splines te permite hacer la forma que vos quieras al ala, el Rhino solo es duro para lo organico.<br><br>Sara.
gracias, despues lo voy a probar
I got around to looking at the works produced in your course. Inspiring shapes and methodology! Here's a <a href="http://plm.com.ar/academico/morfo-e1/gal10/pricuat/superf.htm">more-direct link</a> for anyone who's interested.<br> <br> Thanks for this, leugim.
&iquest;como es el proceso para &quot;cortar&quot; las secciones? es decir &iquest;como generaste las secciones que forman la figura en 3d? Porque yo quiero dibujar una pieza en 3d y luego extraer las secciones de esa pieza a ciertos intervalos para despues armar un prototipo de laminas de carton, parecido a lo que hiciste vos. la pieza en un ala semi eliptica, a la cual hay que sacarle secciones a 45&ordm; del eje, para formar las costillas.
wow, great design!
wow nice<br>
Whit this idea you could be a millionaire! Or you are that right now?
An idea seldom makes anyone a millionaire, my friend. Hard work and a good idea and bunch of luck sometimes does. And in this case, I'm not willing to put in any hard work to make any money off this, which is why the plans are free for anyone else to try!
it's incredible!
I just have a common A4-letter printer, so, how is the scaling for getting the pieces in the right proportion?<br><br>Great design!!!

Don't have the time to read your complete post right now, but on the outro I must make the effort to say that one quick glance tells me this is some seriously cool s8it!! I found 'instructables' by mere chance, and it is like my new baby. A good-looking one. Not one of the type that people consider giving up for adoption. Coo-coo...
I work at a machine shop where we use a Haas V4-500 Coherent Laser. I use aluminum pins to support the material I am cutting and function as a heat sink. However, the pins are constantly getting butchered from repeated use and have to be replaced. In your photos above, it looks as if you are using some sort of grate to do the same thing. Is that true? If so, how is it designed and does it work well?&nbsp;<br /> <br /> Thanks in advance!<br />
&nbsp;You must have a much more powerful laser than we do. Ours doesn't affect metal at all, really. When we laser-etch laptops, it's actually burning off the anodized finish, but the base metal is completely unaffected. So, I guess we just don't have your problem. <br /> <br /> A mesh could help you out, though. The profile it presents to the laser is much narrower, and there's more of it distributed around. Perhaps it would last longer than a few pins.&nbsp;
The old stand is classic!&nbsp; <br />
&nbsp;Woo for late 2008 MacBooks!&nbsp;
