1. IdeaFormer-3D IR3 V1 Belt 3D Printer
The IdeaFormer-3D IR3 V1 Belt 3D Printer is probably the best 3D printer of its kind that you can get from Amazon.
Though there are many, below are some of its best properties such as:
- High Adhesion Conveyor Belt
- Double Gear Extruder
- Silent Motherboard
- Core-XY Structure for Industrial Use
- Filament Run-Out Detection
- Open Source Firmware
The infinite Z-axis with the independently developed hotend makes it ideal to print multiple miniatures or extra-long models, smoothly and continuously.
Though the maximum printing temperature is 250°C which can print PLA and PETG, you can install an external hotend that can print at higher temperatures. The Core-XY structure and the stainless steel linear guide rail under the belt ensure high precision, low noise, and minimum wear.
The dual gear metal extruder, hotend with a Teflon tube, and 45° inclined nozzle ensure smooth feeding of the filament. It also reduces issues of the model not sticking or scraping the nozzle.
The rough conveyor belt surface offers better adhesion, and the two fixtures are there on each side to keep the belt leveled and flat.
Check out the video for a complete review from assembly to printing multiple test prints.
One user said that he was able to go from unpacking the printer to starting printing within an hour.
Another user considers this printer a strong and reliable machine for lengthy and fast printing because of its large build area, MOSFET safety features, and all-metal structure.
One user recommended fully inserting the Bowden tube, or it will not work properly. Leveling the belt or using the LCD GUI is challenging, so it may not suit beginners.
Though due to the 45° angle, flat surface models may not look as smooth and perfect as a regular 3D printer, one user said that the printer is great overall and is priced well for what it offers.

2. Creality CR-30/Naomi Wu’s 3DPrintMill Belt 3D Printer
Another great option is the Creality CR-30/3DPrintMill Belt 3D Printer, widely regarded as one of the best belt 3D printers.
Here are some of the features:
- Creality Belt Slicer (Modified Version of Cura)
- Wear-Resistant Metal Body
- Factory Leveled
- Broadband Power Supply
- Filament Run-out Detection
- Minimum to No Noise
The CR-30/3D PrintMill with its 200 x 170 x ∞mm build volume is good for mass printing or extra large models in one piece. It prints with top-notch accuracy and quality with smooth extrusion and strong adhesion.
It can handle heavy loads and can run for 200 hours in a single run. The power supply switches automatically between AC100-120V/200-240V to prevent any disturbance during long prints.
The rough surface and high-quality material used for manufacturing conveyor belts hold the model firmly during printing and allow it to automatically fall off the belt once completed.
Take a look at the video for a brief review and things you need to know before buying.
One user bought this printer to print replacement door sills for his antique car and it worked great. The side of the model facing the belt usually has an irregular finish however you can make it perfect with post-processing.
Another user said that he faced some issues with setting up the printer and getting the prints to adhere. However, after the first try, it was an easy thing to do. The user recommended using the Creality Belt Slicer as it includes specific profiles that make belt leveling and printing easy.
Though the printer is great for its intended purpose, one user feels it should only be your first 3D printer if you are open to a big learning curve.
Check out the video tutorials covering topics like assembly, printer setup, belt leveling, and replacement along with a G-Code file for tuning your CR-30.
You can buy a Creality CR-30 3DPrintMill Belt 3D Printer at a fair price from Amazon.
3. SainSmart INFI-20 Belt 3D Printer
The next 3D printer you can consider is the SainSmart INFL-20 3D Printer from Amazon. It does have mixed reviews, with some people praising it, then others saying they had issues.
Here are some of its features:
- Textured Nylon Conveyor Belt
- One Click Layer Test
- Well-Positioned Integrated Control Board
- Wi-Fi Printing
- Silent Operation
- Filament Break Sensor
The SainSmart offers a platform to print models of any length and quantity with its easy-to-set-up INFL-20 belt printer. The one-click layer test feature makes leveling the belt, adjusting the nozzle height, and other settings suitable for your filament (PLA, PETG, TPU, or more), much easier.
The nylon belt offers a stable surface with good filament adhesion. It has an easy-to-understand UI and the dedicated SainSmart Slicer enhances this experience to the next level.
The single-axis motion system reduces vibrations and ensures accurate printing. With the triangular design, the printer has better heat ventilation and emits no noise because of the high-quality pulley wheel and silent motherboard.
Thanks to the filament runout sensor, resume printing feature, and stable 350W power supply, you can print hours of models without any interruptions.
Here’s a video on the SainSmart INFI-20 review with a brief comparison with Creality CR-30.
One user recommended leveling the belt with A4 paper pieces because the stock feeler gauge is too thick to give accurate layer height.
Another user got good prints using the Wi-Fi feature on the first try. The user said that there is a lot to learn but once you figure everything out, it prints nice models. Their customer support is amazing as they provide resources and detailed answers.
Some users complained about the bad condition of the out-of-the-box 3D printer. However, they got replacements in most cases.
Check out the resources that can assist you in all aspects of using INFL-20 from assembling to firmware updates and all.

4. MALYAN MA20 V2/MA21 Belt 3D Printer
Both 3D printers are almost the same except for minor differences, such as the MA20 V2 only supports Micro SD and Type C connectivity while the M21 has Wi-Fi feature as well.
- Touch Display Screen
- Silent Motherboard
- Supports Wi-Fi Printing
- Specifically Designed Slicer Software
- Filament Breakage Detector
- High-Quality Stable Power Supply
- Resume Printing Feature
The 3D printer comes with a touchscreen interface and updated firmware to make it a bit friendly for beginners. The softer and wear-resistant belt offers strong adhesion, a smooth surface, and easy removal while reducing belt leveling issues.
In case of filament breakage, the filament runout sensor pauses the printing and automatically resumes once things are right again. This combined with a stable power supply makes it ideal for printing lengthy projects.
You can install an external removable extension roller bracket set to prevent long models from tilting or falling off the belt while it’s printing.
If results are not satisfactory even after increasing the temperature or leveling the belt, simply send pictures/videos to the support team and they will quickly help you.
Here is a short review of the printer from assembly to a cube test print.
One user said that the touchscreen is much better than a spinning knob. However, you should have the experience to use a belt 3D printer efficiently.
Another user liked the design, build quality, and quiet operation. The bed adhesion requires some effort but once set, it is capable of printing some great and long models.
One user stated that the first print came out good but then it started malfunctioning. The user then noticed that the motors were damaged. Though this was the fault of the shipper, the manufacturer should take care of this factor.
Though the printer is easy to assemble and has responsive customer support, one user considers it not a good option for a beginner. The belt leveling is tricky and can lead to disappointments if not done perfectly.
