3D printing demands uniform heating.

Warping remains one of the biggest issues with filament 3D printing. A well-heated build plate improves print adhesion and quality. We designed the Calidum for fast and consistent heating from the beginning. Print big with many materials. The Calidum is UL-recognized up to 120 °C, providing the heat you need for your hardest jobs. Our heat bed easily installs into all 3D printers. Remove the adhesive backing and attach to your favorite build surface.

Made in the USA sticker

Made in the United States

We make our heat beds in the beautiful state of South Carolina. Free shipping is available for all of the lower 48 states.

UL recognized for your safety

Heated beds can carry a lot of power, which is dangerous without the right safety precautions. Our heat bed is a UL-recognized component, because your safety is our number one priority.

Other features

Stick to your favorite surface.

The Calidum uses a 3M® adhesive surface and can stick to glass, copper, aluminum, PEI and more printing surfaces. Peel away the adhesive protective coating, place your build surface and stick it to the Calidum.

The Calidum is perfectly flat and has a thickness of only 0.033 inches (0.84 mm), making it an easy drop-in upgrade for most printers. Our heat bed uses much less space than silicone heating pads. No messy glues required for installation.

We know that all 3D printers are different, and everybody mounts their build plate in a unique way. The Calidum features four through-holes and four cut-away corners to support many mounting situations.

For three point leveling systems

Three point leveling systems are compatible with the four included through-holes.

For four point leveling systems

The cut-away corners give access to leveling screws on 3D printers with four point leveling systems.

Thousands of hours of testing by our customers and us.

We don't just make 3D printing heat beds. We use them too. All PrintIt 3D printers use a Calidum. We firmly believe in our product, its reliability and its performance.

Since its inception, all of our customers have warmly welcomed the Calidum. Before announcing our heat bed, we put it through our most rigorous tests and used it daily for prototyping our 3D printers. This testing leaves us confident the Calidum will meet your 3D printing needs.
