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 in series, in infinite length, or a mixture of both.

With the One Pro 3D Printer, your printed parts 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.

By choosing the Fused Filament Fabrication (FFF) for our One Pro 3D printer, it offers the widest variety of flexible applications. SMEs now have a cost-effective and fast way to produce elaborate and long items directly for their customers. But the One Pro also offers professional production readiness for durable and reliable serial production in consistent quality of your serial products.

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.

The One Pro 3D belt printer by iFactory3D printing an orthopedic insoles with flexible TPU material. The 45° angles print head provides softer edges, a smooth surface and less material is needed

Big impact. Small footprint.

  • Large print volume in a compact design
  • Supports up to 2.5kg spools with an integrated spool holder
  • Stepper motors on the back for a tidy appearance without disconnected cables
  • Printing of special materials possible through the coming enclosure

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
Hot and cold zone on the conveyor belt print bed f the One Pro 3D printer: Temperature mesured fo cold zone is 25.6°C, for hot zone 58.9°C

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.
