Machined tooling contributes to the majority of production costs for many small-run jobs. 3D printing can reduce the cost of plastic cores, molds, and tooling, but there are several considerations to ...

Recently [Stefan] of CNC Kitchen took a gander at using his gaggle of 3D printers to try injection molding (IM). Although the IM process generally requires metal molds and specialized machinery, 3D ...

We’ll admit that most of the Hackaday staff wouldn’t get too far on a skateboard, but that doesn’t mean we can’t appreciate the impressive DIY wheels that [Chris McCann] has managed to cast using 3D ...

Having access to tools can greatly expand an engineer’s ability to build. As technology advances, it tends to become more accessible as it drops in price or increases user-friendliness. Once 3D ...

If you'd like to make a few novelty chocolate bars for an event or just because, you can do so without too much trouble by 3D-printing or hand-carving a relief image, making a silicone mold of that ...

Oak Ridge National Laboratory researchers have conducted a comprehensive life cycle, cost and carbon emissions analysis on 3D-printed molds for precast concrete and determined the method is ...

Orthopedic spine surgeon Dr. Rebecca Kuo says she's found an alternative spine surgery technique that will allow her to do more surgeries in settings that don't have the funding, space or patient ...
