One Pro

Infinite. Flexible. Reliable.

The iFactory3D printer One Pro revolutionizes additive manufacturing via 3D belt printing – from the individual small series to endless printing in industrial standards.

3D conveyor belt printer ONE PRO with pyramid-like structure, black frame and silver print bed; black filament spool in the build area, which is located just behind the display and emergency stop button

The 45° angled print head, combined with the conveyor belt as one of the print axes, allows complex objects to be printed either in series, in infinite length, or a mixture of both.

With the One Pro 3D Printer, your parts to be produced can have bionic features, be reinforced with resin, foam and fiber, and have optimized topology. That’s because our innovation-friendly One Pro 3D printer can print infinitely long hollow parts without support structures.

The wide range of filament variations that map a variety of product characteristics expands the range of possible applications with each new development. Thus, additive manufacturing and rapid prototyping have become indispensable as a cost-effective basis for industrial development for production planning.

Perfecting the use of Fused Filament Fabrication (FFF) for our One Pro 3D printer offers many applications. Small-volume, custom-specification, mostly direct-to-consumer, mid-sized companies now have a cost-effective and fast way to produce elaborate and long one-offs. But the One Pro also offers professional production readiness for durable and reliable serial production of a wide variety of products in consistent quality.

The One Pro brings a new generation of professional 3D printers ready for series production to your company, with reliable and low-maintenance innovative technology, for manufactory and industrial production.

Leave your competition behind with unbeatable per-unit manufacturing costs and products you can print flexibly, in high quality and in any quantity with the One Pro.

Excellent print quality

  • CoreXY-System
  • Precise movement without distortion
  • GT2 belts can be individually tensioned for better printing results
  • Hard Y-stop to avoid nozzle crashes and protect the conveyor belt
  • Laser-cut aluminum parts for precision and consistent printing results

Simple change

  • Quick change of the conveyor belt due to removable precision rollers
  • Tool-free, uniform clamping system over the entire conveyor belt
  • Easy calibration with only four screws

Advanced functions

  • Floating build plate with a hot and cold zone to avoid deformation in long parts, covered by a borosilicate glass plate for perfect flatness.
  • A stepper motor with a gear ratio of 27:1 drives the front roller, eliminating the need for a GT2 belt that would sag, skip or need retensioning.
