[Benjamin Klemencic]

3D printing is awesome and it started  at the Metalab Vienna (to become affordable resp DIY) as far as I know but what about 4D?

I'd love to read your comments!


Here are some impressive examples of 3D I've duckduckgoed (googled) for recently. Please feel free to link to other examples!

☞ 3D printing metals 
(using laser sintering as a difference to Fused Deposition Modeling FDM used in RepRap, Makerbot and other DIY 3D printers. Filament is most often the bioplastic *) PLA (Polylactid with properties like Polyethylen high-density HDPE or the thermoplast ABS (Acrylonitrile Butadiene Styrene which is based on petroleum (*bad bad bad*)))
