A SmarterEveryDay BBQ Knob Shows 3D Printing Can Compete With Injection Molding

Printing at scale, on camera

Destin from SmarterEveryDay has spent years asking whether 3D printing can replace traditional manufacturing. The latest test case is a BBQ scrubber knob, and the answer is closer than you might think.

Slant 3D, the company behind the new Portals on-demand service, redesigned the knob for mass production. The video shows how a production 3D printing farm can churn out thousands of identical parts. The goal is to prove that additive manufacturing is not just for prototyping anymore.

The numbers behind the claim

The video does not publish exact per-unit costs. That is typical for this kind of demo. But the visual evidence is persuasive. A wall of identical knobs rolls off a 1,000-machine farm while Destin explains the process.

The real comparison is speed and flexibility. Injection molding requires expensive tooling. If the design changes, you need a new mold. With 3D printing, you just update the file. For low-to-mid volume runs, that is a meaningful advantage.

What this means for hobbyists

This is not a story about desktop printers. The Slant 3D farm is industrial scale. But the underlying point applies to everyone who owns a printer: the line between prototype and production is blurring.

For small businesses, that means faster iteration. For designers, it means lower risk when launching a new product. And for consumers, it means more things can be made locally instead of shipped halfway across the world.
