Most 3D printable parts are designed to limit overhangs to 45 degrees or less. That's because maker-style 3D printers (technically FDM) build each layer from the bottom up, fusing the current layer onto the previous, and if there's nothing below a layer, the plastic will sag (or worse yet, form a glob and potentially ruin your part).
We started this design series taking a look at iterative design with bikes, and now we're ready to shift gears (hah!) to tackle an increasingly popular and more radical form of transportation: the skateboard. There's a long history of 3D printed skateboards online, from the daredevils at Braille Skateboarding who will skate absolutely anything to the early board designs on Thingiverse, but it wasn't until we joined Frog's skateboard challenge that I committed to designing a functional 3D printed
3D printing materials and manufacturing processes go together hand-with-hand: often choosing a material, also dictates what 3D printing processes are available to use. But with such a vast selection of 3D printing material options, how can a designer make an informed decision?
One of the most challenging tasks facing designers and engineers new to 3D printing is having to navigate through the vast number of 3D printing processes and materials to find the solution that is best for their application.
Selecting the right manufacturing technology for a particular application can be hard, even to the most experienced designers. With rapid developments in digital manufacturing technologies, like 3D printing, the potential benefits for designers can easily be overlooked without sufficient knowledge of the subject. The purpose of this article is to
As far as mass production methods go, sand casting is one of the oldest. 3D printing is one of the newest. Dutch design and engineering consultancy Arup has figured out how to combine the two, allowing one to enjoy both the low cost of the former and the physical complexity
If you're making something for yourself and casting it in resin, you can probably live with the inevitable air bubbles that appear in the object. But if you're an industrial designer prototyping something a client's going to see, bubbles are a no-no. That's why professional prototypers like Eric Strebel use
