XYZprinting da Vinci Jr. Pro X+

The XYZprinting da Vinci Jr. Pro X+ is an FDM 3D printer from XYZprinting with a 175 x 175 x 175 mm build volume.

Specifications

The XYZprinting da Vinci Jr. Pro X+ represents a pivotal transition in the consumer-level desktop 3D printer ecosystem. Historically, XYZprinting was known for its closed, proprietary hardware ecosystems that heavily relied on chipped filament cartridges, restricting users to proprietary materials. With the introduction of the "Pro" series, and specifically the da Vinci Jr. Pro X+, the manufacturer shifted toward an open-filament paradigm, offering more advanced controls, improved thermal management, and compatibility with third-party slicers.

Calibration

Achieving dimensional accuracy and flawless surface finishes on the da Vinci Jr. Pro X+ requires precise tuning. Follow these 8 detailed calibration steps:

• Chemical Degreasing of the Build Plate

Ensure the glass print surface is thoroughly cleaned before every print. Apply a generous amount of 99% Isopropyl Alcohol (IPA) to the cold bed and wipe it down with a lint-free microfiber cloth.

Common defects

• Hardware defects and mechanical weaknesses
• Bowden Tube PTFE Degeneration: The internal PTFE liner inside the quick-release hotend degrades over time when printing near the 240°C limit. As the PTFE decomposes, it shrinks and forms a gap between the tube and the nozzle, resulting in a "plug" of semi-molten filament that causes severe under-extrusion.
• Symptom: Inconsistent extrusion, clicking feeder, and eventual printing failure.

What it is used for

Optimal Scenarios

• Classrooms and STEM Labs: The fully enclosed chassis, lack of exposed high-temperature components, and low operating noise make this machine highly suitable for educational environments where student safety is essential.
• Concept Prototyping with PLA: The printer delivers highly detailed, dimensionally accurate PLA prints.
