iFactory Factory One Belt 3D Printer Review

5.7/10

The iFactory Factory One Belt is not your standard 3D printer. It takes a bold approach with its conveyor design, allowing for continuous printing and angled layer deposition that you won’t find on most machines. If you’ve ever felt limited by traditional print beds, this model is designed to break those boundaries and open up new possibilities.

The iFactory Factory One Belt first appeared in 2020 as one of the earliest consumer-focused conveyor 3D printers, offering capabilities that were once limited to industrial systems. At a time when continuous printing and angled layer deposition felt experimental and out of reach, the Factory One Belt made these features accessible to hobbyists and small businesses. Makers who had struggled with splitting long parts or juggling endless print cycles suddenly had an affordable tool that could tackle projects in a single run. 

Early feedback from the 3D printing community was enthusiastic. Forums and social media posts quickly showcased endless belt-printed props, cosplay weapons, and production runs of parts lined up and ready to roll off the machine. Guides, slicer profiles, and modification tips circulated rapidly, helping new users get started. The Factory One Belt became a go-to option for anyone curious about conveyor printing, blending stability, innovation, and approachability into one package. 

An overview of iFactory conveyor belt concept

iFactory3D’s approach centers on making continuous belt printing user-friendly and practical. The angled print head and rolling belt allow prints of virtually unlimited length, batch production without operator intervention, and creative new applications. While traditional FDM printers limit you to the size of the print bed, this design scales beyond those boundaries. For makers aiming to produce long props, small-batch products, or experimental designs, the Factory One Belt represents a leap into fresh territory. 

Despite the unique mechanics, it isn’t overwhelming to learn. The guided setup, touchscreen interface, and solid frame give beginners confidence while letting experienced users push the system further. It’s a printer that takes a once industrial-only feature and puts it within reach of everyday creators. 

Unboxing and setup

Setting up the Factory One Belt feels a little different compared to a conventional FDM printer. The packaging is secure, and parts are well-organized, so you don’t spend hours sorting screws and wires. Major components arrive preassembled, which speeds things up. The manual guides you through the steps clearly, and within about an hour, you can move from unboxing to the first calibration run.

Our initial impressions

The Factory One Belt immediately gives off an innovative feel from the first unboxing. The frame feels solid and reassuring, and the conveyor system looks more professional than many users expect from a consumer machine. The touchscreen interface responds quickly and is easy to navigate, which adds to the positive first impression. Once assembled, the printer has a commanding presence. Its angled head and long belt strongly suggest it’s capable of projects no ordinary FDM printer can handle.

Many users have highlighted how reliable the belt movement feels during long jobs, and for us, that smooth motion inspires confidence for multi-day runs. Noise levels are noticeable but manageable, on par with other open‑frame machines of similar size.

Design and specifications

The Factory One Belt stands out for its angled print head combined with a moving conveyor platform, which sets it apart from standard printers. This design allows prints of virtually unlimited length and enables continuous production of batch parts. Its reinforced metal frame gives the machine stability during long jobs, while the belt itself is durable and resistant to warping under heat.

Technical specifications at a glance:

  • Build volume: 180 mm wide × theoretically unlimited length
  • Nozzle: 0.4 mm (interchangeable)
  • Layer height: 0.1 – 0.4 mm
  • Filament types: PLA, PETG, TPU, ABS, and more
  • Bed leveling: Assisted belt leveling via touchscreen prompts
  • Heated belt: Durable surface for strong adhesion
  • Extruder: Direct drive for flexible materials
  • Connectivity: USB, SD card
  • Display: Responsive touchscreen interface

The Factory One Belt really shines in print quality. Standard models have clean surfaces and consistent layers. The angled deposition benefits overhangs and bridges, reducing the need for excessive supports. Thanks to the conveyor, printing long parts, such as props, rails, or batch runs of functional pieces, is seamless.

For small, detailed models, the angled layers can sometimes make surfaces look slightly different compared to flat-bed printers. With some tuning in your slicer software profiles, you can minimize this effect and achieve results that rival traditional machines. The belt’s grip is strong, so adhesion is reliable from the first layer to the final pass.

Test print results of Factory One 3D printer

To see how it performs, we ran several test prints: accuracy cubes, long prop segments, and a continuous run of small parts. The accuracy cubes came out very close to CAD dimensions, with only minor adjustments needed in slicer settings. Long props were printed in one go, smooth and stable, without the need for joining multiple pieces. The batch run of small parts demonstrated how convenient the conveyor is, you can set it to print overnight and wake up to a collection of parts neatly rolled off.

The iFactory Factory One Belt is an exciting machine, but like any advanced tool, it comes with a few quirks you should be ready for. You’ll notice them mostly in the way the conveyor-belt system moves, how the angled deposition works, and the demands of multi-day prints.

Print adhesion that’s too strong

One of the first things you may notice is how firmly prints can stick to the belt. While solid adhesion is generally a good thing, it can make part removal difficult and sometimes damage delicate models.

To ease removal, many users lightly sand the belt surface to create a finer texture, or apply a thin layer of glue stick, hairspray, or PTFE-based spray before printing. These create a barrier that ensures your prints stick just enough without fusing too strongly.

Belt alignment drift

Because the conveyor system is constantly in motion, the belt can gradually drift out of alignment if not monitored. This usually shows up as parts being skewed or layers not stacking properly.

Re-tensioning the belt using the adjustment knobs typically solves the issue. It’s a good habit to check belt tracking every few prints, much like you would with a 3D printer’s belts or pulleys.

Stringing on long prints

Continuous printing introduces more opportunities for stringing, especially on long or tall models. This occurs when the filament oozes slightly during travel moves.

The best way to minimize it is by fine-tuning retraction distance and speed in your slicer. Lowering the nozzle temperature by 5–10°C can also reduce oozing. Some users report that enabling coasting and wiping settings in the slicer further helps keep surfaces clean.

Comparisons with Competitors

While there are pricier or more industrial conveyor printers available, the iFactory Factory One Belt is praised for balancing print width, continuous output, and approachability. It costs more than an entry-level FDM machine, but you’re paying for a stable frame, polished design, and a feature set that puts continuous printing within reach of hobbyists and small businesses. If you prioritize industrial-grade speed or very wide builds, other models might suit you better, but for dependable conveyor printing in an accessible package, the Factory One Belt holds its ground.

Our final verdict

Looking at the Factory One Belt in 2025, the question is whether its unique conveyor style matches what you want from a printer. Its strengths remain clear: the ability to print parts of unlimited length, produce continuous batches without interruption, and handle flexible materials with a direct drive system. These features still make it stand out, and if your projects often involve oversized models or repeated production, this machine feels like a natural fit.

On the flip side, you’ll need to stay mindful of its quirks. Belt alignment needs routine checks, strong adhesion can make part removal tricky, and the price tag sits higher than most entry‑level printers. If you’re after a small, quiet printer that just works out of the box, you might prefer something simpler. But if what excites you is the creative potential and efficiency of conveyor printing, the Factory One Belt still holds its place as a worthwhile choice in 2025.
