Hellbot Adonis

The Hellbot Adonis is an FDM 3D printer from Hellbot with a 160 x 160 x 160 mm build volume.

Specifications

The Hellbot Adonis is a budget-friendly desktop FDM (Fused Deposition Modeling) 3D printer designed and distributed by the Argentine 3D printing company Hellbot. The printer is aimed at hobbyists, students, and beginners looking for an affordable entry point into additive manufacturing. It features an open frame design with a compact footprint, optimized for printing standard materials under stable ambient conditions.

• Hotend and Extruder: The printer utilizes a single Bowden extruder setup, where the filament feeder motor is mounted on the vertical frame. This configuration reduces the mass of the print head carriage, allowing for smoother carriage translation.

Calibration

The budget-friendly construction of the Hellbot Adonis requires regular manual calibration to compensate for mechanical tolerances.

• X-Axis Gantry Alignment (Single Z-Lead Screw Compensation)

Because the printer uses a single Z-axis lead screw, the right side of the X-axis rail can droop if the roller wheels are not adjusted correctly. Turn the eccentric spacer nuts on the right-side roller carriage until they fit snugly in the slot without wobble.

Common defects

• Hardware defects and mechanical weaknesses
• Bowden Fitting Wear: The pneumatic fittings that secure the PTFE tube to the extruder and hotend can wear out quickly. During retraction, the tube can slide back and forth in the fitting by 1–2 mm. This play ruins retraction settings, leading to severe stringing. Replacing the fittings or installing locking clips is recommended.

What it is used for

Best use-cases:

• Beginner's Introduction to 3D Printing: Well-suited for users looking to learn the basics of calibration, bed leveling, and slicer settings.
• Standard PLA Decorative Prints: Ideal for printing small visual models, toys, and custom containers using PLA filament.
