3DP IDEA | 3D-printed Wrench from Desktop Metal

November 10, 2025 Applications 8559

These wrenches from Desktop Metal feature a 3D-printed gyroid infill, reducing weight by 30% while maintaining strength, showcasing the company's fast, high-density metal printing technology rather than being a consumer product.

Look at these wrenches and you’ll almost instantly notice something different about them. Unlike the die-cast wrenches you see with solid metal bodies, these unique tools from Desktop Metal come with a textured inner surface, featuring multiple holes and cavities.

Why is it noteworthy?

The inner surface of these wrenches uses a gyroid-style in-fill, commonly seen in 3D printing to fill up inner spaces with support material while conserving plastic. The gyroid inner mass gives these metal wrenches their strength while simultaneously cutting down on material and weight. The result is the same, functional tool but with nearly 30% less mass and weight.

What we like

The parts have a much higher and more uniform density (up to 99%) than other metal 3D printing methods while being much faster too

What we dislike

The prototype wrench is less of an actual product and more of a showcase of Desktop Metal’s capabilities
