Creality 3DPrintMill Belt 3D Printer, Infinite-Z-axis printing
What is an Infinite-Z 3D Printer?
Simply put, the 3DPrintMill(Creality CR-30) is a cross between a traditional 3D printer and a conveyer belt. This means two things:
- Continuous, unattended part printing. Parts are 3D printed, the heated belt advances, and the parts detach themselves and fall into a bin. No more constantly prying pieces off a heated bed and starting the print process again. The 3DPrintMill can turn an entire 1, 5, or 10-kilogram roll of plastic filament into dimensionally accurate plastic parts with no human supervision.
- Extremely long (theoretically “infinite” along the Z-axis) 3D prints. By tilting the bed 45 degrees, the back of the printed object advances out of the 3D printer- while the front is still being printed inside the printer. The longest print out of the 3DPrintMill to date is a 20 foot/6 meter long bar- all one piece, produced by a machine only 66cm long.

Pre-Order now, 1st batch will be shipped out from USA, in the middle of May.
The 3DPrintMill is not a “kit”. The printer comes separated into four main parts for shipping, the base, front, rear, and control panel. It takes less than 30 minutes to attach these parts with the accompanying Allen keys.
On the other hand, if you start with a box of aluminum extrusion, rods, belts, rollers, and other raw parts bought directly from a factory in China and passed onto you untouched yet at a substantial markup, it may feel like a bargain. But in the course of assembling a 3D printer entirely from scratch without the precision alignment surfaces and jigs available in a factory, errors become cumulative. A twist along one axis, combined with skew along another can be nearly impossible to troubleshoot. This is why, if you want good print quality and dimensional accuracy it’s critical to minimize the number of parts a customer will have to assemble.
Simply attaching a gantry to a base is a proven design- but try to assemble the whole gantry from individual pieces without a perfectly flat surface plate as a work surface and you’ll find there are multiple points at which deflection is introduced. Many sound printer designs become unworkable or require elaborate software correction because the precision alignment of parts from a kit to .01mm or better tolerances is unrealistic at the average person’s dinner table or office desk. This is why every 3DPrintMill (Creality CR-30) is first tested at the factory, then comes to you as a nearly finished unit.
