Large & Small LED Lamps

cults3d

These two LED lamps employ identical fundamental geometry, yet exhibit subtle differences. I initially designed the larger one and had to make compromises with its geometry due to difficulties in accurately integrating a hemispherical top with twisted slabs forming the side columns. To minimize noticeable discrepancies, I enlarged the lamp. Upon commencing printing, I discovered an efficient method to substantially reduce the mismatch between the top and columns. This approach was applied to the smaller lamp, resulting in a more complex polygonal rail sweep shape replacing the simple hemisphere. The inspiration behind this geometry stems from a Rhino3d Grasshopper forum post where a question was posed about creating a building with twisted slab sides. A user provided a method for designing twisted slabs, which I adapted for these designs. This blog page details how I integrate architectural design principles into my 3D printing projects: http://birkbinnard.com/blog/from-architecture-to-3d-printing/. The large lamp is substantial; it printed in 48.5 hours with standard print parameters of 100 mm/sec and 0.200 mm layer height. If you have a printer capable of producing this size, I recommend starting with a full reel of filament. The smaller lamp, on the other hand, printed in 12.5 hours under identical conditions. Both lamps accommodate either battery-powered or wall-powered "puck" LED lights.

Battery-powered puck lights can be sourced at large home improvement stores or by searching online for "LED puck light".
