We’ve got our sights set on Amazon Prime Day, which is running from June 23-26, 2026, and the bargains for some of the best 3D printers are hot! But Amazon is not the only place to snag a great deal. Manufacturers are holding fantastic sales on their own websites, and most are offering free shipping along with can’t-miss filament bundles. Even if you’re not in the market for a new 3D printer, Prime Day brings out the best sales on filament and accessories.
