Belt 3D Printers: 6 Best Options

Belt 3D printers have changed additive manufacturing by allowing the creation of objects that can be extremely long, almost endless. This new development allows for continuous, automated production of longer items without any human involvement. Here are some popular belt 3D printers, along with their technical information, features, and benefits to help you make an informed decision.

1. Creality CR-30 3DPrintMill

Key features:

• Print Technology: Fused Filament Fabrication (FFF), Marketed as Fused Deposition Modeling (FDM)
• Layer Resolution: 0.001 micron / 0.1 mm
• Supported Extruder Nozzle Diameter: 0.4 mm
• Extruder Nozzle Temperature: 464°F / 240°C
• Filament Compatibility 1.75 mm Diameter: PETG, PLA, TPU

Pioneering belt 3D printer with great demand in the additive manufacturing scene, Creality CR-30 is sometimes referred to as the 3D Print Mill. Its unusual design, with a conveyor belt and a print head placed at a 45-degree angle, lets it print continuously and produce an infinite range of objects. Supported by an isosceles right-triangle frame, the printer's robust CoreXY design helps it run smoothly and reduces shaking during printing. 

Strong nylon makes up the conveyor belt, which is robust and helps hold completed prints for easy removal. Great for printing various materials, the heated bed can reach up to 100°C. The CR-30 allows the nozzle to be heated to 240°C, thereby enabling the use of additional filament types, including TPU and PETG. Because of its very quiet foundation, which allows for tranquil printing, the printer is fit for both home and office use.
