XYZprinting da Vinci Jr. WiFi Pro

The XYZprinting da Vinci Jr. WiFi Pro is an FDM 3D printer from XYZprinting with a 150 x 150 x 150 mm build volume.

Specifications

The XYZprinting da Vinci Jr. WiFi Pro is an enclosed, desktop FDM (Fused Deposition Modeling) 3D printer tailored primarily for educational institutions, beginner enthusiasts, and low-volume prototyping applications. A critical evolution in XYZprinting's product strategy, the "Pro" designation reflects the integration of an Open Filament System, which permits the use of third-party consumables, alongside standard Wi-Fi connectivity and G-code execution capabilities. This machine packages simplified, user-friendly mechanics within a safe, self-contained shell.

Calibration

Achieving clean prints and dimensional accuracy on the da Vinci Jr. WiFi Pro requires careful calibration of the mechanical and extrusion settings. Follow these 8 detailed steps:

• Chemical Cleaning of the Build Surface

Clean the glass build plate thoroughly before starting a print. Spray a generous amount of 99% Isopropyl Alcohol (IPA) on the cold bed and wipe it down with a lint-free microfiber cloth.

Common defects

• Hardware defects and mechanical weaknesses
• Feeder Tension Arm Failure: The plastic tension arm on the Bowden extruder assembly is prone to developing hairline cracks under constant spring pressure.
• Symptom: Filament slippage, motor clicking, and severe under-extrusion.
• Solution: Replace the plastic extruder assembly with an all-metal dual-gear extruder upgrade.

What it is used for

Optimal Scenarios

• Schools and Educational Labs: The fully enclosed chamber, mechanical safety switches, and quiet operation (<48 dB) make it ideal for classroom environments where student safety is essential.
• Detailed PLA Prototyping: Ideal for printing architectural models, toy prototypes, and visual maquettes with clean surface finishes.
