Strømg Lump Leaks is a ceiling lamp designed by Lamp Lumps (LL).

The used technique is self supporting interlocking of pieces (without gluing, screwing or nailing) of 547 different pieces of polypropylene routed with a three-axis CNC.

The conception and materialization is mixed by using digital and analogue means.

The first name Strømg is the junction of the English term strong with the Danish surname Strøm. Strong, because it is a robust three-dimensional puzzle witch form is the result of small variations in each of the pieces. Strøm, because this work is an homage to Holger Strøm and his IQ Lamp.

The Lump Leaks surnames suggest, for instance, the leaking drops of water or the leaking of information. The abstraction of the concept results, morphologically, in a piece that is the materialisation of the metaball modeling technique that was widely used by pioneers of digital media in architecture in the 90’s.


I grant you this design information as long as you:

1 - create unique variations in the objects you produce based on this design;
2 - never sell any of the produced objects based on this design;
3 - never sell this design or designs based on this design;
4 - keep the objects you make to yourself or give them at no cost whatsoever;
5 - use these conditions in designs based on this design;
6 - share your variations in Thingiverse;

Material: 0.6mm Polypropylene sheets
Router Tip radius: 0.5mm

1 - Use the dxf files to create your g-code files for your machine;
2 - Cut, order and mount the pieces;
3 - Note: use a CD marker to write numbers if you do not want them routed in pieces\\\\' surface.

Hope you enjoy it.

Lumper. Can you tell me a little about the software used in the creation of this piece. Specifically what software was used to break down the overall shape into it's separate pieces with connecting tabs. VERY COOL!!

Thanks! I used Blender, Rhino and Grasshopper. I made the shape in Blender and passed it to Rhino. Then I made a custom definition in Grasshopper. You can check on their website. There is a large community and you can find all the information there.

Thanks for the information. I've been looking at Grasshopper. I really appreciate the work you've put into this design and it's very generous for you to share it with the rest of us. I have a CNC router and was thinking of making a larger version of your lamp in a floor model. Perhaps a 1/16" thick PP. Do you think the design can withstand the weight of itself on the bottom disk? Also can you give me a rough idea as to the size of your lamp so I can adjust the scale appropriately.

Cool! Yes, shure I can. Maybe it is better to contact me by email?

Ya that sounds like a good idea. What address can you be reached at?

Register in thingiverse 8-)

Another neat thing is that 'str
øm' also means electricity in Danish :)

(What a nice lamp!)

I wonder if I could make it out of onyx on my 3 axis stone cnc. Thickness is an issue. Can't get interesting onyx in slabs any thinner than 2cm. Could probably use tiles at 1cm thickness. hmmm

Thickness and rigidity of onyx are an issue as the lamp design needs the flexibility and "plastic" stiffness to keep its form. Also, I believe that with stone one would have to scale the object a considerable amount and then weight would be an issue. It looks an interesting challenge to rethink the design for stone and bigger scales: that is why I venture on making these designs.

A Nice Design. I think i'll try to make one.

Is there a reason you used a cnc machine instead of a laser cutter? Also do the parts just assemble in the order they are numbered, or is there more complexity to the layout?

Thanks! Look forward to see your version. Please do follow the conditions.

I used a cnc because I own one and also because polypropylene in a laser cutter produces very toxic fumes and no shop would cut it for me. I can't remember of other kind of material that is translucent and that can go to the laser cuter.
The parts just assemble in the order they are numbered. Complete a first ring and when it is closed pass to the next one above in the next case (hope i did explain it well).

Thanks! I'll probably be using some other material, so we'll see how that affects the outcome. I see from your profile your an architect, its nice to see someone else with a design background.

I am curious to see your outcome. Keep in touch.

That looks pretty cool, Luimper.

Yet another reason we need a conveyer belt on makerbots..

Thanks DaveD. A conveyer belt would handy in a makerbot!

And with the lamp having 547 pieces, it would definitely be needed if somebody wanted to try printing this on a makerbot/reprap!

It would be interesting if somebody would try it on a makerbot/reprap...
