What Makes it Special

The 3DPrintMill (Creality CR-30) is a cross between a traditional 3D printer and a conveyer belt. With its conveyor-belt style print bed and 45° printing angle, this innovative belt printer allows you to print continuously, which makes printing long props in one-piece and batch printing possible. In addition, you can also print perfect unsupported overhangs with the printer. If you are running a 3D Print Farm to do mass production or if you are a cosplay enthusiast looking for a printer to print the costumes, the CR-30/3D PrintMill is definitely worth trying.


Key Features

200mm×170mm×∞mm Build Volume

With a build volume measuring 7.87in×6.69in×∞mm(200mm×170mm×∞mm), the infinite Z-axis build volume on the CR-30/3DPrintMill allows you to print an endless batch of prints or one very long print in one piece.

Conveyor Belt

Made of wear-resistant material, the conveyor belt on the CR-30/3DPrintMill features excellent print adhesion and balanced conveyance. To smooth out your workflow, the CR-30 is factory leveled, and prints will fall right off when the belt reaches to the end, no removal is needed.

Stable Core-XY Structure

The stable and sturdy Core-XY precision structure with isosceles right triangle support gives you an extraordinary printing experience.

Additional Features

Dual Gear Metal Extruder

More precise filament extrusion and better filament grips and heat resistance can be achieved with this dual gear metal extruder, uplifting the printing performance to a new level.

Broadband Power Supply

The power supply unit on the CR-30 will auto-switch between AC100-120V/ 200-240V, and provides safe and stable performance during your long hours of printing.

Filament Run-out Detection

Your print will pause and wait for you to load filament before continuing. No need for restarting the project from scratch.

Ultra Silent Board

Upgraded silent board reduces the noise level of the CR-30/3DPrintMill.

Exclusive Slicer

Creality Belt, a modified version of Cura specifically designed for the CR-30, provides you an easy start to this innovative belt printer, you can do batch printing with this slicer with ease and tune the print settings to unleash the full potential of the CR-30.
